Founded in 2013 on the core values of economic, environmental, and equitable sustainability, STEMACH Design + Architecture is dedicated to implementing a passion for thoughtful, innovative designs.

Our Firm

At Stemach Design + Architecture we make the process of planning, designing, and permitting your project as easy as possible by using the latest three-dimensional modeling techniques to clearly convey appearance, operation, and viability to you, your contractor, and all public parties involved.

And we're passionate about what we do…

We know that people live, work, and play in the spaces we design. With emphasis on our prime goals of economic, environmental, and equitable sustainability, we deliver a thoroughly holistic design-approach that results in successful buildings with a design sensitivity toward both aesthetics and efficiency.
Through these goals we hope to contribute toward a sustainable future.
