Platt Builders is one of my absolute go-to builders in the luxury design industry. Their thoughtful, organized construction process and exceptional craftsmanship make them an outstanding partner on every renovation project. Clients feel supported and informed from concept to completion; transforming what can be a daunting construction journey into a an enjoyable experience. As an interior designer, I especially value their in-house custom cabinetry — a dream for anyone who appreciates beautiful, detail-rich millwork executed with precision.

They consistently bring my design concepts to life with enthusiasm, creativity, and the skill needed to execute at a high level. When they say they can build anything, they truly mean it — I have seen them bring many complex ideas to life time and time again. Whether you’re a homeowner planning a renovation or a designer or architect seeking a trusted building partner, Platt Builders is a highly skilled team that you’ll be grateful to be working with. Together, we've created multiple award-winning spaces and I look forward to many more collaborations ahead.

We’ve had the pleasure of working with Platt Builders on a recent high-end residential project, and we couldn’t be more pleased with the experience. As an interior and landscape design+build firm, we rely on trusted partners to help bring our vision to life—and Platt Builders delivered with exceptional craftsmanship and attention to detail.
Their custom carpentry work was beautiful, precise, and executed with a deep respect for our design intent. Every piece they created enhanced the overall aesthetic and quality of the space. They were collaborative, professional, and a true asset to the project.
We highly recommend Platt Builders to anyone seeking finely crafted custom woodwork and a team that takes pride in their work.

We hired Platt Builders to build our home. From the very beginning we have been impressed with the professionalism and guidance that they have provided. The entire team is extremely experienced, and thoughtful. I came to this after a career spent selling building materials. I consider myself an expert in that field. What I needed was someone who was willing to collaborate with an expert to provide the home that I wanted. I didn't want or need someone to tell me how to build a home. I needed someone to work with me to implement my vision. Platt Builders expertly filled in the gaps and assembled a team of craftspeople and tradesmen to make it happen.

Platt Builders has done two projects for us over the past five years. We replaced siding, trim and windows. The process they went through from estimation to completion was predictable, thorough and professional. We have had other contractors do work in our home before. Never again. Platt’s attention to detail and craftsmanship is incredible. They walked us through the process and answered any questions we had. The project manager checked in with us on a regular basis to be sure we knew what to expect next. We couldn’t be happier with their work and plan to call on them again in the future.

We completed our 4th project with Platt Builders this Fall. We have enjoyed the professionalism from Platt Builders - their employees and their subs are responsive, friendly and knowledgable. We redesigned our master bathroom, added a closet and linen cabinets. The process for the master bathroom and closet was fantastic. When we started our master bathroom project we knew we wanted natural wood and Steve was so helpful guiding our selection of color and cabinet style. We choose teak and could not be more THRILLED with the result- the wood grain matching is impeccable- the bathroom now feels like a Scandinavian spa. Platt Builders also suggested an efficient way to re-work my closet so I feel like I have more space. We have also been fortunate to have Platt Builders replace our siding and windows, but what started it all was our kitchen renovation and porch addition 5 years ago. This company is our go-to contractor.

We hired Platt to complete a major home remodel - they built a staircase, replaced all doors, flooring, exterior siding work, and a roof. The experience was one of the worst we have had with a contractor, and this is our third home and third major renovation.

From the start of the project we had concerns. The project manager made clear to us that he was unhappy at Platt and it showed. He was often late and failed to respond in a timely way. We later learned that he was applying to other jobs and left Platt right after our job was complete.

The workers sent by Platt to our home seemed unskilled. Nearly ever part of the work had to be redone - both minor (floors with large gaps, poor carpentry, painting issues), and major (roofing, water issues).

We found significant safety issues with some of the work completed. Platt installed a metal cap on our clay lined chimney resulting in significant water leakage and potential carbon monoxide blockage and mold. When we raised this issue with Platt, instead of fixing it, they hired a law firm. It seems they have a pattern of failing to fix issues and instead using lawyers instead. Eventually they paid for some repairs to the chimney but only after we started to take legal action.

We still have ongoing disputes with Platt about water leaking in another room, which we believe is due to how they applied the roofing materials, and poorly painted balusters. Instead of working with us, Platt again hired a law firm (curiously, they now have a new law firm).

It's clear to us that Platt has become too big in recent years, and can't keep up the good work they might have done in the past. We've since used other contractors in the area who are excellent.
