Joshua and Gary had so much enthusiasm for our project and we really enjoyed working with them. We had very definite ideas of what we wanted and they incorporated everything we asked for and more. They were very good about taking notes and sending us confirmation of topics discussed. We wanted to take advantage of the water view and natural light and their design skill accomplished the open concept we wanted to achieve. We love the columns, the arches, the arbors, the round windows and the casual yet elegant feel. > The General Contractor also enjoyed working with Joshua. His professional architectural design made his job so much easier and Joshua was always there for support throughout the project. Joshua and Gary made the entire project a very positive experience. **★★★★★ — epalaveeva, May 2011** > We engaged with Masterson Studio for a small basement remodel. We had never worked with an architect before, and Joshua was professional and extremely helpful, using his expertise to scope out our project and outline the steps we needed to take to make it a success. **★★★★★ — Moo Designs, May 2011** > I employed the services of Masterson Studio for documentation of as-built conditions and construction details for a large residential project in Seattle. > Joshua Masterson was such a professional. His drawings were very detailed and he always produced more than what I asked for. The new construction details for proposed work were suburb. He has great mastery of construction methods as well as excellent design aesthetics. > I referred other clients to him and they were all very pleased with him and his work. I wouldn’t hesitate to recommend Masterson Studio in the future. ## Selected projects - [Issaquah Remodel](https://www.houzz.com/hznb/projects/issaquah-remodel-pj-vj~1239) - Location: Not specified - Photos: 8 - [Decatur Cabin](https://www.houzz.com/hznb/projects/decatur-cabin-pj-vj~1240) - Location: Not specified - Photos: 14 - Description: This addition consists of a new master suite for a custom built cabin on Decatur Island.
