Our “Builds” Team:

Robert Capen, Lead Carpenter & Job Site Supervisor Robert comes to CTA with 30+ years of experience in framing and carpentry. Starting at just seven years old, he built everything for himself from skateboards to treehouses with work always underway – and it still is! His past projects have ranged from single-family homes and remodels to multifamily homes, commercial buildings, and even house boats. His love of wood stems from its highly modifiable nature, and especially its feel and unique smells, all of which keeps him enthralled in his work.

Damon Harris, Lead Carpenter Bio coming soon!



Eduardo Aguirre, Carpenter Eduardo began framing at fourteen years old before joining in his brother’s cabinet shop and working with him for many years; he now has over 35 years of experience in the construction field with skills in all areas of expertise. He is also our house salsa dancer, having danced semi-professionally since he was young!

Sam Parke-Fagerness, Carpenter Sam brings to the table a wide range of experiences in architecture and construction from his background working as a Carpenters Apprentice in the family business. Since graduating from the University of Washington with a Bachelor of Arts in Architecture he is now working to bridge the gap between design and realization. On the weekends Sam likes to stay active and get outdoors in the local mountains.

Lea Howlett, Cabinet Maker Extraordinaire Lea has been our go-to cabinet maker for the past couple of years and does stunning work in our new homes and remodels. He is always on site when we need him and he feels like one of the crew!
