The team worked efficiently, stayed on schedule, and delivered beautiful results at a very competitive price.

David Mulligan is as good as it gets when it comes to a general contractor in the Marin area. If he…read morehas availability to do your project you must hire him. PROJECT DESCRIPTION: This was my first remodeling project and I chose David and Builders of Marin after interviewing ~4 different contractors. The project was a to-the-studs renovation and expansion of a ~1,500sqft, 2 bed, 2 bath ranch home into a ~3,500sqft 4 bed, 4.5 bath contemporary home. Complicating the build was (1) that the house was on a steeply sloped, small lot, (2) needed an entirely new foundation, and (3) was on a narrow street with no parking. WORKING WITH DAVID AND BOM: Working with David on this project was a pleasure. I hear friends describe their interactions with contractors and consider myself very lucky that I was able to work with David and his team on my project. If I ever do any remodel I will only do it if I can get David to do the work, and if I ever buy another house I will get David to visit the property with me. In fact, I would probably hire David first and then shop around for an architect. David is highly responsive, detail oriented, and does what he says he will do every time. From a work-style perspective, David is the ultimate high-integrity professional -- which is difficult to find in the construction industry at times. HOW DAVID AND BOM ARE BETTER THAN OTHER CONTRACTORS: David and BOM are better than other contractors based on three very important qualities: estimate accuracy, follow-through and execution, and crew / construction quality. ESTIMATE ACCURACY: One of the most difficult things about a high-end residential construction project is getting anyone to tell you how much anything costs. David will do the work to come up with an accurate quote, and will give you a reasonable, sober estimate as to how much different scope changes will change the budget. He brought our project in on-time (incredibly rare) and on budget (when adjusted for us changing the project scope and adding ~700sqft midway through). He does not over-promise or under quote (as many GCs do), and also doesn't mark-up everything by 30% (as many GCs do). Furthermore, if he finds cost savings midway through the project he will help you realize those. FOLLOW-THROUGH: As mentioned above David is accurate at estimating project costs and timelines. He is able to BE accurate because he has the crews and sub-contractor relationships to get the work done on time. Unlike many GCs who over-extend themselves during good construction markets, David has a number of quality crews with incredible site foremen (Kim was ours -- the best!) and is able to realistically budget their time to avoid delays. Furthermore, David believes in doing what he says he will do and will make the construction personnel be there to get the work done. CREW / CONSTRUCTION QUALITY: David believes in retaining the best people and has been working with many members of his crews for 20+ years. Many of his master carpenters started out as unskilled labor with him decades ago, and he has taught and mentored them up himself. What this has allowed David to build is a team obsessed with construction quality that knows how to do things the right way, and can get things done quickly. Furthermore, he has a deep bench of talent that he can put to work on projects to get them done on time, the right way. The commitment to finish quality from David and his whole crew is maniacal, and they are able to pull-off flawless contemporary designs that require high build quality. I would like to call out Kim, Omar, Jesus and the whole BOM team who worked on my house -- they are all incredible craftsmen and wonderful people to be around. For all of these reasons and many more, I wholeheartedly recommend David and Builders of Marin for your next project. I would also recommend you get on his docket early -- he gets booked up fast!

We decided to buy an old house on a large piece of land where we could build our forever home. We…read moreknew the house was old, but we did not realize how bad it was. Little did we know at the time, what a massive undertaking this project would be. After talking to several contractors and on the recommendation of our Architect, we selected Builders of Marin to build our home. We picked David because there was something honest about him. What you see is what you get. Having experienced other contractors in the past, that is a huge positive to us and not something we normally encountered. The original plan was to expand onto the existing house but we realized that everything was rotten after decades of neglect by the previous owner and ended up tearing everything down back to dirt and started over. This turned out to be bigger than we ever planned or budgeted for. Along the way, David was able to guide us though all of it. He stepped in and problem solved a range of issues, including many interior design issues that was not even his responsibility. From the mundane of relocating an outlet, to the life changing "holy sh*t, we are having twins", David we need an extra bedroom, David and his experienced crew, handled it all to made our dream on paper become a reality.

We have been working on a 2nd floor addition to a 100 yr old house. As one can imagine, there are…read moremany significant structural issues that may arise unexpectedly when opening up walls and seeing how people build things 100 yrs ago. David and Ray have been incredible since the beginning of the process, helping us navigate through all the structural concerns and always trying to find a value engineering approach - whether it was optimizing depth of foundation work, or finding ways to reinforce old windows, coming up with ways to get headers into locations where there isn't the space, and/or proposing alternative shear wall options when there isn't room to fit things. Ray, our project engineer, has been the best communicating and responding to all our questions and worries. He carefully reviews the problem at hand that arise and often will provide 2 or 3 possible options that our builder can work on. With our current project, Ray is always super prompt to resolve any issues via call or email, or video conference and if necessary an onsite visit to inspect the construction phase. He was just crawling in our crawlspace the other day and notified our builder if some items that needed to be addressed to maintain a positive continuous connection from 2nd floor down to 1st floor and to crawlspace foundation. We are now adding the 2nd floor framing and almost done the most stressful part of the project. We have done 3 major remodels in the past with other firms where it was difficult to get in touch with anybody. With Ray and David at Simplengi Engineering, it has been a very refreshing experience to have experts that promptly responds to all our concerns. Value engineering, great timely communication, attention to detail, common sense, simple and smart engineering. We highly recommend Ray and David and Simplengi Engineering for any structural work. Simply great engineering. We don't plan to do another remodel for 100+ years but if we did, we would hire Simplengi 100% for sure.
