Voted Portland's Best Custom Home Builder | Best of Houzz 2015-2021!
With over 30 years experience building custom homes and specializing in steep slope construction throughout the Pacific Northwest, Gerald Rowlett, the owner of the award winning Westlake Development Group, is an Oregon native who takes pride in his team’s ability to create a rewarding and successful design and build experience for all homebuyers. Inside every house we’ve ever built lives a family calling it home. And for us, no other feeling of satisfaction and accomplishment could possibly compare. It motivates us to offer great service and acts as our catalyst for creating beautiful homes—both inside and out. If you’re not excited about pulling into your driveway at the end of each day, we haven’t done our job. We want your home to be an impeccable source of never-ending comfort… an exhibit of your exquisite sense of style and a definitive representation of the unique person in you. We’ll draw on nearly 3 decades of industry expertise and insight to make sure it’s everything you ever dreamed of and more.
