Brian V. came over to check out our house and to see if our expectations were realistic. He was very calm and organized. We found him very knowledgeable, especially about the San Mateo County permit & planning department. We interviewed a couple of other architeture firms, but found Brian at The Kastrop Group to be the best. Once we hired Kastrop, Brian quickly set up a time to come measure the entire house. Our 80 year old cottage had no central air/heat, so Brian referred us to an engineering firm that would help work out all the  computations that the permit department would need to approve this addition. As we moved through the architectural design process, Brian came up with solutions that would give us what we needed, along with a few suggestions that would provide more storage near our new second bathroom. We found Brian and Kastrop to be very accomodating with no drama. We like it when there is no drama. Once the architectural drawings were approved, we wanted to know if we had budgeted enough for the renovation. So, Kastrop had a General Contractor look at the plans and visit our house to give us some preliminary numbers. This was a big help for us and we were so thankful for this extra step. The Kastrop Group is an outstanding architecture firm that took us through the entire architecture design process with a gentle hand and no drama. We were grateful for their professionalism and their recommendations. If you are considering renovating your house, your first stop should be The Kastrop Group for impressive architectural expertise and being a great partner to navigate the county permit process.

Luis and his team spent about 30 minutes understanding my requirements and provided detailed and honest feedback. They explained that since my existing patio is built with Alumawood, enclosing it with a regular wood frame would not be appropriate. The proper options would be either to remove the existing structure and rebuild it from scratch or use a specialized Alumawood sunroom system. Even though iBuilders Design and Build could not take on my project, I truly appreciate Luis and his team for their transparency, professionalism, and willingness to provide honest guidance upfront. Their responsiveness and helpful advice made the process much clearer for me.

We had the pleasure of working with Jill Finn of TANGERINEdesign LLC when our longtime designer was…read moreunavailable -- so she walked into a situation where we were already feeling a bit off balance. But from day one, Jill exceeded our expectations. The project involved tearing down an old, dilapidated screened-in porch that had never really worked for us -- too cold in the winter, too hot in the summer -- and transforming it into a usable interior room. We wanted to keep the light and airy feel of a porch while gaining insulation, comfort, and year-round usability. We also wanted ideas for built-ins: maybe a window seat, maybe bookshelves -- we weren't quite sure. Other contractors over the years had taken one look at the porch and declined to get involved due to its age and condition. Not Jill. She had ideas right away. Jill brings so much energy, creativity, and practical knowledge to the table. Even while juggling big personal commitments (like her son's graduation across the country), she delivered several strong design ideas within a few weeks -- and they were fresh, inspiring, and budget-conscious. She collaborated easily with our civil engineer, adjusting her drawings quickly to meet his needs. She also understands our local codes and regulations really well, and met directly with our contractors to make sure her designs were realistic and executable before we got too far into the process. On top of all that, Jill has a fantastic personality. She made the experience fun and engaging, and she brought a sense of momentum and confidence that really helped us move forward. I can't recommend Jill highly enough -- her creativity, responsiveness, and enthusiasm make her a true gem. If you're considering working with TANGERINEdesign LLC, you're in excellent hands.

The pace of the job was very smooth right off the bat and only picked up once the work started. During the design phase the team including Liane were very pleasant to work with. Liane was extremely patient and helpful while she met us at two design stores to assist us in choosing colors and layouts. Once the work started, we were very impressed with the site prep as Eli delivered on keeping as much dust out of the the rest of the house. He made sure crew setup plastic sheeting throughout the whole bottom floor with zipper doors included so we could still access the living room and upstairs. From here, we were very pleased with the pace of things. Eli and his team are very eager to work and do not make you wait. The demo happened very quickly and before we knew it we were moving very quickly through rough electrical and plumbing. The rest of the job went very smoothly and ended up being ahead of schedule. At any time if something was not right, Eli was very open to our suggestions and critiques and always made sure his crew fixed the issue. Once the work was done Eli was very responsive and always made sure any minor issues/details were address and fixed.

We worked with EDR to completely remodel a duplex into a single family home that hadn't been…read moretouched in 60 years. Eddie and Sarmad did a fantastic job in delivering the project. From the start of the design project, they used high quality sub contractors for design, engineering, and all the trades in the house. Fernando, our project manager was incredible. He approached the project with a keen eye for details and took total ownership over the sub contractors. He would stop by almost every night to ensure that the subs were performing their work and not leaving or damaging any other contractors' work. Sarmad is a problem solver. He sees an issue and thinks through how to solve it, then presents clear options to choose from. Throughout the process, we were not surprised by unanticipated expenses - all changes were clearly explained and we had the option to make changes via clear change orders. EDR uses Buildertrend for all program management and billing, which made payments, change approvals, and scheduling tracking seamless. While this sounds like a basic requirement in 2026, not all contractors use these services which just adds friction to the process. We couldn't recommend EDR more for the quality of work on our house, the schedule execution, care for detail, and just taking care of our project. Along the way, we never felt nickel & dimed, and the value of their services definitely exceeded our expectations.

We liked Sarmad's communication style - methodical and efficient, no extra words. Sarmad was incredibly efficient at managing our project. He made sure to schedule inspections right as we reached each checkpoint in the construction, so every day was optimized. As a result, our project from demolition to completion took just about 4 months. One aspect of our project that we worked closely with Sarmad on was to customize a computer server closet. Specifically, we wanted the closet to be soundproofed and have its own temperature control. Sarmad was very accommodating in our requests to install soundproofing insulation, and even suggested QuietRock drywall to enhance soundproofing. We also worked with the team to install conduits throughout the extension for future cable runs. Throughout the process, Sarmad was responsive to our questions and our requests.
