We hired Addition Building & Design to renovate our kitchen. We're delighted and excited at the finish product. Mike, the owner of Addition Building & Design went above and beyond to surpass our expectations. His team which included a fantastic designer, experienced cabinet makers, tile setters, Raul-painter, diligent electricians, and plumber worked collaboratively to build our family a custom kitchen. Raul was fantastic and a man with many talents. The craftsmanship is evident in the final product. Cost was reasonable and competitive. Time frame was reasonable and consistent with building a large custom kitchen. We are incredibly happy with our elegant & custom kitchen. Additionally, on the opposing wall-we changed it to sliding glass door. Mike is incredibly responsive and compassionate. Our family will enjoy this kitchen for many years to come. I highly recommend Mike. read more

We did a complete gut remodel on a 1928 house, and trusted Mike & Addition Building and Design with the project. They knocked it out of the park. Mike is a no-nonsense contractor - he was quick to come by for an estimate, and gave us very competitive pricing. We appreciated Mike's transparency as well. Unlike a lot of companies that ask you to pay $2-3k for them to draw up some plans before even giving you quotes for a scope of work, Mike had a detailed breakdown of costs in our hands for every element of the project, within a week of his visit to the property. About the job itself - Mike's core crew of builders are incredibly professional and do great work. And all the subs he uses for tile, flooring, cabinetry, countertops, plumbing and electric are top of class. We had lots of people from different trades coming and going from the property during renovations, and people from other trades would comment on the quality of the drywall work, the plaster, the tile, etc. I can't stress enough the craftsmanship these people brought to the job, and they did a gorgeous job incorporating the historical details and architecture of our house with the new modern elements. Finally, every time we had questions about any part of the process, Mike was available by phone or text to guide us through any concerns, from design to construction to permitting, and he stopped by the property at least once a week to check on the work and review progress with us. His years of experience are evident. Finally: Mike's team got this job done in record time, and when he promised us three months to completion, he came through. The project did go a little longer than initially quoted, but that's because we added a few extras onto the project after seeing what a nice job his team was doing. We wouldn't hesitate to use Addition Building & Design again - and would wholeheartedly recommend hiring them for your job. You'll be in good hands. read more

Mike Ross is my go-to guy for any and all things relating to my house. He's incredibly nice, even though all of the jobs he's done for us have been on the small side. (I really, really wish I could have him come and re-do the whole house!) I can tell you he puts an enormous dedication to quality into everything he does. He's put in a number of windows, all of which have improved our old house's livability; he's put in a door and installed an exhaust vent in my kitchen and a utility shelf in my laundry room. I realize these sound like mundane tasks, but I live in a old house that probably doesn't have a plumb line in it. Working on this house is not easy. Anyway, I wish I could give more stars. read more

I was introduced to Mike by a business associate of mine. He had recently redone several parts of his house (kitchen, hallway, master bed/bath) and was extremely satisfied with the results. The main goal was to redesign my garage, but also to change the layout of my backyard. I have a lot of junk and the garage became a place I disregarded for quite some time. (I couldn't even park my car inside the garage anymore!) Mike was able to come up with a design that allowed me to keep everything organized, with a lot of space, in a very sleek new look. Mike was a straight shooter from start to finish, clearly telling me what to expect in terms of time, cost, and his opinion about the best way to go about getting me the results I wanted. He definitely did not disappoint and finished the project on time and for not a penny more than what was originally quoted. read more

I have worked with Mike and his team for years now. The quality of homes that they work on is amazing. It is wonderful as an Interior Designer to see the build and remodel projects go from client's dreams to beautiful home. read more

Relationship: Client Project Date: March 2016 Project Price: more than $100,000 Addition Building & Design, Inc recently completed a very large addition/remodel to our home.

Mike was recommended by friends, who also had a project completed by Addition Building & Design, and my family can't thank them enough! We will hire Mike and his team again for our next project and continue to recommend Addition Building & Design for new construction & additions. read more

I've known and done business with Addition Building & Design for over 15 years. As a Business Manager for Celebrities and high net worth individuals, one of the services I provide to my clients is highly personal financial concierge and consulting. I've referred several clients to Mike Ross and his team of experts. Mike is a leader in this industry. Addition Building & Design will renovate your existing space, add square footage, improvements, upgrades, or, a complete tear down and build your dream home to your exact specifications. In addition to our significant and frequent interactions where I represented clients, Mike has also done extensive work to my home. My personal needs have been upgrades and improvements. I'm also interested in energy efficiency, green building, and always desirous to add resale value. With these in mind, Mike has incorporated my desires in every aspect of his work, energy star appliances, sustainable materials, and for me, (as a financial expert and efficiency guru), Mike is ALWAYS meticulously conscious of my budget. So, I can confidently declare that Mike Ross is MUCH MORE than just a "General Contractor"...... he expertly guides his clients through every minute detail! It is for this reason that I not only recommend him highly.....he has received the "DARLING" seal of approval! (And I'm a VERY picky customer!) Just last week, I called Mike and asked him to do some minor electrical work in my home. He replied immediately, and sent one of his subcontractors other to the house. They replaced a few wall outlets....and a couple other minor wiring issues, and in the middle of the job.....made a couple amazing suggestions that I had not considered.... this was regarding receptacles. They were able to replace my existing items with receptacles that had USB charging ports built in! This was WAS AWESOME! And that tiny detail has made things so much more convenient! Also....adds to resale value..... and eliminated need to carry charging cables and adapters all over the house. The electrician also identified a couple other things that I was not aware of.....that I might want to keep an eye on, and made 3 VERY valuable suggestions, that would not only save electricity.....but VALUE, and convenience as well. Mike Ross gets to KNOW his clients....what's important to them, and literally custom tailors his services, and the products he uses..... our homes are our castles, right? Mike and I have a decades long business relationship. His loyalty, honesty, integrity, and reputation, has been the single most important thing....to ME.....over my 20 years of owning my home. I still have a couple more "major" improvements to make.....and Mike is already on top of things! He knows my budget....and I know that I can always count on Mike! For ANY job.....no matter how big, or small. As I contemplate my retirement plan....(in 6-8 years)...... I need to figure out a way that I can bring Mike to Costa Rica....where I am planning on building my dream home (today, it's all an idea in my head.....).... but I know that Mike will ALWAYS be there for me! Addition Building & Design absolutely has a CLIENT FOR LIFE here at Darling Gardens. read more

Mike came highly recommended by his colleague. I trusted his colleague, so I trusted Mike without much thinking and contracted with him to do a complete remodeling and expansion of existing home. But I had to stop him from further carrying out our contract after a week of contracting with him. I was refused of my financial losses even after many attempts. So I had to take legal actions. After spending many hours of filing paperwork and making calls, and 7 months after, I was able to get some of my losses back, but not all. I believe there are better contractors out there that you will not have to take risks with your hard earned money. read more

Addition Building and Design renovated three bathrooms and a kitchen in our home. We are very happy with the results. Mike and his team were efficient, diligent and hardworking. The project was completed timely and within budget. They gave attention to each and every detail and it showed. The quality of their work is first rate. They did everything possible to make sure that the final product met our expectations, which it did. We would definitely use Addition Building and Design again and would recommend them without reservation. read more

It really a 2.5 out of 5. The company is okay, I signed a contract with them for an ADU and canceled within the 3 days rights to cancel. I spoken with Christine initially then it was to Mike Ross. Christine was nice and acted like she knew a lot about building an ADU. However; she did say if she didn't know the answer she would find out. Mike was all business and seem very busy when we met him. I asked a few questions about separate electric meter and gas meter but they didn't really give me an accurate answer. I then called LADWP and the GAS company and they gave me an answer and I conveyed the answer back to Christine and Mike. I decided we weren't a good fit and canceled my contract. They kept my deposit stating they went to the city to see how large an ADU I can build. I spoke to my lawyer and she said I should get the deposit back but I guess they needed it more than I did. My house was a corner lot and the rules for a corner lot is different with the certain set backs for LA city. They initially said I can build it with no problem with the setbacks. This is just my experience. read more

I first discovered Mike when my daughter hired him to completely remodel her newly purchased Bel Air home. It was perfection and could have been in architecture digest. Then her in-laws used him to completely makeover their new Beverly Hills condo. Another triumph! Around that time I wanted to change my kitchen in my main house and Mike accomplished that perfectly with reconfiguring and adding cabinets and a much needed Miele refrigerator to help with the pandemic hoarding. I was beyond happy with my kitchen and still am. So it was a no brainer when I decided to make my Guest house a legal ADU. Mike attained all the necessary permits and now we are in the process of the renovation. It is all going ahead of schedule and after a few short weeks I am already picking out paint colors!!Addition Building and Design is a family business with Mike at its helm steering beautifully! I would heartily recommend Mike for any renovation from one or two rooms to an entire estate. No matter how large or small your project is, he's your guy. I am so happy with his entire staff, from his office to his workers and Mike oversees all. He will make your dreams happen. Run don't walk and hire Mike for your next renovations. I know you will be as happily satisfied as I am! read more

Mike and his team of amazing professionals recently completed an addition on our home. Not only is the work exemplary and of the highest quality, but the courteousness and consideration shown to our family during construction was unmatched. With a new baby on the way, we had a limited time frame to get the second story addition done, and Mike met our (very challenging) timeline and had the work done on time despite the extra cost and difficulty it presented to him. Every person who came through our house was extremely considerate of my pregnancy and our three year old son. They were neat and unobtrusive and kind. In terms of the work itself, Mike worked hard to realize our vision and address all of our concerns. The space we had to work within to fit the new rooms was not an easy configuration and Mike made everything fit like a glove- and seamlessly! ...it fit in with our house so well that the flooring team who came in couldn't even believe it was new construction. I would highly recommend Mike and Addition Building Design for any construction needs and we are looking forward to using them for future projects. read more

My family was looking for a reliable contractor. We got referred to Mike Ross and his company. He was very easy to communicate with during the process , always answering the phone and explaining in details what's going on. We were relocating from San Diego and needed a reliable contractor on the field. The job was done in a timely manner and looked better than what we imagined. I was very picky with the details and Mike had the patience to take the time with the finishing touches. So glad we worked with Mike Ross! read more

I had the pleasure to work on my new property with Mike Ross. He was happy to guide me through the process and give a free evaluation which property to buy. Contractors have a reputation for being slow and always coming up with extra costs, however working with Mike was stressfree- I had access to an app that guided me/showed me progress/changes daily. I could see what was happening at my property while at work. I am happy to refer Mike to all my friends/network and know he would do the job perfectly without being overcharged. He's been in business for a very long time and his expertise and portfolio prove it! Highly recommended! read more

Mike Ross and his team did a beautiful job in our home in Sherman Oaks; it was a full remodel emphasizing the kitchen and master suite and it came out better than we imagined.

I hired Mike after vetting 10 Contractors for my master bed room with bathroom and kitchen remodeling. I knew he was going to be great because he brought design boards. The biggest thing I loved was the 3 D renderings he brought for the Kitchen and Bedroom custom for my house. Once Ok'ed he got to work with in a few days. The work is almost done and the whole process has been good. I am very anxious see it completed! read more

We had an old bathroom that needed upgrading . It also had a number of repairs that needed to be addressed. My son was pleased with the work that ABD IMAP on his home remodel so I decided to use them as well. We are pleased with the outcome. The craftsmen that worked on our project were not only professional but their workmanship was meticulous. They thought through measurements and complex designs to deliver a quality product. Jose, the foreman kept me informed throughout the process of what was completed and what needed to be done. They let me know when they would be at my home so that I could plan my schedule accordingly. Finally, they cleaned up their areas daily leaving minimal disruption. We installed a hanging toilet and a hanging vanity to maximize space a facilitate cleanup. The shower used subway tile with a mirror niche. I wanted a clean, streamlined look so I chose white for tiles and walls. Colors would be provided by towels, rugs and accessories. As a matter of fact, we want to open up our living room area and we will be hiring Mike for phase 2. read more

We hired Addition Building & Design , Inc to completely remodel our house in the Palisades and build a new addition to convert our house to a more open flow design. This addition was complex and Mike, the owner, and his team 'nailed' it. Never any issues with any of the inspectors due to Mike's attention to detail and ability to execute professionally. Mike was committed and present at the site all the time to ensure a timely completion and quality project. The new kitchen is beautiful and functional ---we love it!. My wife and I would hire Mike again for our next project! read more

We had Addition Building & Design remodel our master bedroom and bath last year. Not only did the master bedroom need a serious facelift, but it was consistently hot in the summer and cold in the winter. Mike figured out our issues with the ac and his ac subcontractor balanced the ac vents and upgraded our 20 year old ac system. The project was supposed to take 3 weeks, but took more like 4 weeks due to the tile I picked out that was out of stock. All in all, Mike and his team did such a fantastic job on that remodel for us, that we have hired him again to remodel our kitchen and children's bathroom. We couldn't be happier with the Addition Building team and Mike's communication and professionalism. We will definitely hire the ABD team on our next project which will be our backyard... our dream pool and outdoor kitchen! read more

Having purchased our first house in Valley Glen, North Hollywood, we were aware it was in need of serious remodeling. A 1950s Ranch-style home, it came complete with peeling wallpaper, musty carpeting, and even some dilapidated walls. As first-time homeowners we were prepared to spend more money to improve it, but weary when we began meeting contractors. Buyer's remorse already set in when we interviewed several contractors who were either aloof or unscrupulous. Then we were fortunate enough to find Mike Ross. He immediately allayed our stress with his professional and forthright demeanor and his integrity was as rock solid from the day we met him through the several months it took to complete our large renovation. While we had some specific things we wanted in our house, Mike and his team took our wish list and far exceeded our expectations to help truly realize the vision of our dream. Originally a three-bedroom, fourteen-hundred square foot home, our remodel brought an addition of a thousand square feet as well as an overhaul of the landscape; this prospect was particularly daunting for uninitiated owners such as us, but Mike's consummate professionalism shone through and made the task exponentially less stressful for us. As well as a new 850 sq.ft Master Bedroom, including a fireplace, and a steam unit in the bath, we added a cozy home theater room, laundry room, and the once forgotten backyard brought a new deck and patio with a trellis. Furthermore, because we went green and made it a smart home, we're already more energy efficient. In several rooms, as well as the main hallway, for example, Mike installed solar tubes and the amount of natural light that bathes the house is amazing. Even my mom, when she came to visit, was always looking for a light-switch. As our contractor, Mike Ross took the reigns to steer the project and keep it on course and he did so exceptionally. Mike and his team were as attentive to the quality of every nook and corner and he always sought our approval and happiness. Consistently communicative, he always kept us in the loop about progress and was always there to answer any questions and concerns. When an unforeseen contingency did arise, Mike assuaged our concerns by taking action ASAP to rectify the problem. Mike's team, too, all take pleasure in their efforts. An eclectic group of skilled artisans and craftsmen, they are all polite, punctual, and proud of their work. Thank you, Mike Ross, for your outstanding leadership, your impeccable standards, and your commitment to our happiness. read more

I love referring Mike Ross, as he always makes me and my team look so good! My clients love him for his knowledge, professionalism, timeliness, and the list goes on and on! It's a real pleasure to work with a contractor that makes it look so easy! Thanks Mike! read more

I would put zero stars if possible. Mike is the hardest person to communicate with. If you work with him and try to communicate via email get ready for a frustrating experience. Not the type of service you would expect. Seems like he is checked out or just not passionate about his job - which might be the last thing you want from an expensive contractor. Very disappointed in him and his team. Since my original post Mike has tried to pass the blame onto his architects and anyone else except for himself. Only after he read my post did he send me an email longer than a sentence long and finally called me! So if you want him to contact you I suggest reaching out to him on here. It is very frustrating in general when a person doesn't own up to their faults. I originally gave him the address to my place and a description of the work that needed to be done... So he had the ability to check it out before. He either did not do his due diligence on the job or just wanted to waste my time because yesterday was the first time he told me he didn't do this type of work. Make sure that you document everything with this company. He did try to "compensate" me for lost time... Which sounded like he was trying to pay to get this post off his review. If he did this with me he could've taken the same approach with other posts. read more

We ALMOST went with Addition on our bathroom remodel... but I did some last-minute investigating and changed my mind. Here's what happened: Mike told us that Burbank city code required a bathroom door be 36" wide, so he would have to widen our current door frame and install a new door. That was going to be an additional $1000. Since no other contractor had mentioned this to us before, I called the Burbank building division to check this out for myself. And, guess what - Mike was wrong. The 36" requirement is for front doors only. Either Mike didn't know what he was talking about... or he wanted to make an extra $1000. Both possibilities scared us. The search continues for a licensed contractor with workers compensation insurance. read more

I love-love-love my new wood floors and I loved hiring Addition. Mike's crew did exactly as promised, completing the work within a weekend (does that ever happen?!) .. I have the new wood floors in the whole first level of the house, new paint on all the walls, tile in the guest bath, a new ceiling to replace outdated 'popcorn,' and gorgeous, sexy recess lighting. The price was phenom and he worked with a very tight budget. Most importantly, a mistake was made when one of our glass pieces was damaged and Mike's foreman corrected the damage on the spot. I know it's scary to bring people into your home, and you hear horror stories, but I can wholeheartedly recommend this company. Feel free to contact me personally if you would like more details. read more

I want to say thank you Mike.Ross and his team.. I had my home completely remodeled and it looks amazing. They were neat and courteous and always on time.. If you are looking for a trustworthy contractor Mike Ross is your guy. I have my friend remodeling her home now because of how amazing mine came out. read more

We had had some bad experiences with other contractors- lazy workers that took forever to get anything done. Mike and his posse remodeled our kitchen quickly and efficiently. They were nice guys that minded their own and got the job done. read more

We hired Mike Ross & Co. to completely overhaul 3 bathrooms and our family room in our 1920's Hancock Park/Larchmont Spanish Revival. The previous owners had "updated" it into a 90's mess. Bad wallpaper, failed walls, horrible home depot bathrooms... Mike was there at 8am with his crew the day after we closed escrow. All of his workers were polite, clean and very respectful. They got to work immediately and never skipped a beat. He was fair on every single aspect of the job. Of course change orders came up (lovely to tear down wallpaper and have a wall fall down!) that we did not anticipate or budget for but we were able to come up creative ways to stretch our funds. Anything that I wasn't happy with he immediately addressed and made right. I plan on using Mike for future work and can't wait to recommend him to all our friends. Honest, reliable and top notch on all levels. read more

At a Sherman Oaks Chamber of Commerce meeting, I had the pleasure of meeting Mike Ross and hearing him present on behalf of his business, Addition Building and Design. I decided to hire him to do a sunroom for my school's check-in and waiting area. So far, his crew has been very professional. They show up on time. The work is excellent, and they clean up meticulously at the end of each day. Mike knew my financial situation and helped me afford this much needed addition to my studio. I trust and recommend him. He's a great family guy and an ethical businessman, too. read more

I was very glad to get a referral to Mike at Addition Building & Design for my recent master bathroom remodel. I've had past experiences with contractors that finished late and cost more than my original estimate. Mike did what he said, at the price he quoted, and actually finished almost a week ahead of schedule. They also provided a bunch of very good solutions to my big ideas. Not only was he a construction professional, but he realized the importance of communication. He let me know everything that was going on so I was able to plan my family/home life around the work schedule so that the remodel was ACTUALLY easy. I would recommend this company to anyone that I know professionally or personally. 5 STARS! Not sure why Yelp is filtering my review for Mike since I think it would really help others know his integrity and my satisfaction read more

My family and I were on a tight budget and even tighter time crunch. Mike did an amazing job working with our needs and kept an open line of communication every step of the way. I honestly felt that Addition Building & Design really put our wants and needs at the forefront. Everything was as promised and looks great! Thanks again. read more

We hired Mike on to do a major remodeling of a new house, and we are very happy with the results. The job included kitchen, bathroom, new floors throughout the house, converting a crawlspace into a storage area, and just about everything else you could think of from plumbing to electrical. Mike cares about the results of his projects, and was at our house every day (we were not living there yet) to check on the progress and met with us weekly. He used the BuilderTrend app to post photos of the progress. If something wasn't to his standard, he would have the workers do it again. All of the workers and subcontractors I interacted with were very friendly and helpful. I never felt nickel and dimed, and there were a number of issues that popped up during the remodel that Mike solved for us without extra charge. I never had a hard time reaching him or his office. Remodeling is stressful under any circumstances, but it helps a lot to have a contractor who you trust to listen to your needs and get everything done. read more

We worked with Mike at Addition Building & Design to remodel our master suite which included moving some walls, relocating the laundry room and the master closet and a full master bath remodel. I can't say that everything went smoothly as things will inevitably come up with any major remodel on an old house but everything was definitely handled professionally with all the issues addressed in a timely manner and with full transparency on timing and costs. We're extremely happy with the final result... Mike was very accommodating, and the project manager Jose was professional and sympathetic to any concerns that came up. They were able to accomplish all our design goals and keep the integrity of our historic spanish style house intact matching the rest of the house. I would definitely consider using Mike again on the next big project and would highly recommend this company to anyone looking to do any sort of remodel on their home. read more
