Sean Conta - Owner

With a background in engineering and construction, Sean has been working in green building and energy efficiency for the past 8 years. He is formerly a certified passive house (PHIUS) rater, HERS rater, Built Green verifier, and has extensive experience with sustainability and high performance homes in the Seattle area.


The world of "green building" is evolving rapidly and there is an enormous amount of information out there to sort through. Through training and involvement in hundreds of projects with many of the top builders in the region, plus his own projects, Sean has developed a large functional knowledge base to cut through the confusion and opinion and offer clear direction for your project. In fact, if he wasn't working in the industry, Sean would be "geeking out" on construction and building science in his spare time anyway!

Sean is also an avid skier, drummer, "car guy", husband, and father of two.

Matt Kull - Site Supervisor, CPHB

Matt’s background is in ecology, he grew up in a house his father built, and began his journey to carpentry and building science working on his own home. He finds a deep sense of satisfaction and gratification working with his hands - whether carpentry, cooking, or gardening. Drawing on this background, building high-performance homes is a natural extension of his interest and expertise. 


Matt approaches carpentry as a study in best practices and continuous learning. He is deeply committed to learning and instituting current building science and best practices to build sound, efficient homes that last. Craftsmanship continuously informs Matt’s approach to carpentry - bringing artistry to execute details and produce beautiful, durable homes. Matt is also a PHIUS Certified Passive House Builder. 


When he’s not on site Matt can be found exploring Puget Sound with his wife and daughter, cooking with his immersion circulator or smoker, working on his own house, and tending his vegetable garden. He is also passionately fond of structural screws and believes the finest tool you can use is a freshly sharpened block plane.
