We recently completed our new home with Westlake Development, and the experience was nothing short of excellent. From the very beginning, the team established trust and delivered on it consistently throughout the entire process. In an industry where transparency and dependability aren’t always easy to find, Westlake stood out as a partner we could rely on. We always felt like they had our best interests at heart, and that gave us a huge sense of confidence as we moved through such a major life project.

The quality of construction is evident in every corner of our home. The attention to detail, the craftsmanship, and the thoughtful execution really set their work apart. Everything feels solid and well-built, and it’s clear they don’t cut corners. Knowing that the house isn’t just beautiful, but also structurally sound and built to last, has given us real peace of mind.

Another standout was their strong relationships with vendors and subcontractors. Everyone who came on site reflected the same professionalism and standards we saw from Westlake themselves. The process was smooth because they’ve built a network of people who care about doing things right, and that made the entire project more efficient and stress-free for us.

Finally, their eye for design was invaluable. They didn’t just build to plan—they offered thoughtful suggestions along the way that made our home both more functional and more beautiful. Small design tweaks and recommendations added a level of polish that we might not have thought of on our own. It’s clear they understand not just how to build a house, but how to create a home. We couldn’t be happier with the finished product, and we wholeheartedly recommend Westlake Development.

I've had the opportunity to see Westlake Development Group's homes as both a photographer and a real estate agent. Without reservation, I can say Gerald Rowlett and his team build some of the finest homes in the NW. The marriage of form, function, and aesthetics is consistently of the highest caliber, and their work has been featured in the NY Times and other national and international publications. One home in particular stands out, which won a national architectural design award. Spanning almost 14,000 square feet, it was built nearly 15 years ago, and yet when my colleague and I sold it, it still almost looked brand new. The sliding glass panels could be moved with the touch of a finger, a testament to not only the quality of materials, but also the meticulous construction process. One point of emphasis I've seen in his work is the ability to maximize any available view. Colorful sunsets and sunrises have undoubtedly provided homeowners with many fond memories. Westlake Development Group builds homes that last and stand the test of time.

We had an incredible experience working with Gerald and his team at Westlake Development Group to build our custom dream home. From our very first meeting, Gerald brought a level of professionalism, transparency, and genuine care that immediately set them apart. He spent the time to find us the perfect location and held our hand every step of the way!

They listened closely to our vision and made it even better with his creative ideas (he’s a wealth of knowledge!!) and thoughtful guidance. Throughout the entire process from design to completion, the team’s communication was consistent and clear. Every step felt collaborative, and we always knew what to expect.

Gerald’s craftsmanship standards and attention to detail are truly exceptional and unmatched in this industry. Our home not only reflects our style and needs but also shows the quality and pride Westlake puts into their work. We’re beyond thrilled with the final result and couldn’t imagine trusting anyone else for making our dream home a reality!

Kevin Mahaffy on Westlake Development Group

Working with Gerald Rowlett and his team is such a pleasure. He's truly a visionary, and his passion for building with innovative design and high quality products can be seen on every project. The Westlake team is committed to covering every last detail!

Working with Westlake Development Group has been a positive experience. Gerald Rowlett and the Westlake team have been amazing throughout the entire process: from selecting a location to designing the home, building it, and resolving issues after we moved in. Gerald kept the project moving forward and finished on time. His attention to detail was impressive and we ended up with top quality results. The only area for improvement was budgeting, our project went over budget and we didn’t have visibility into this until after construction was well underway. Building a completely unique and custom home, we encountered several unforeseen issues. Gerald and the Westlake team were quick to help us resolve or correct all of these issues. We are truly enjoying our new home. If we have the opportunity to build another house, we would be delighted to work with Westlake Development Group again.
