About Us

At Studio G+S Architects, we’ve helped our clients exceed their architectural goals and expectations since our founding in 2004. Our specialty is residential architecture. Our style often integrates both modern elements and traditional detail together to create inviting, comfortable, rich spaces.

The firm started with an emphasis on residential renovations. That work made real the transformative power of design. Buildings which just didn’t work or “feel right” became light-filled, warm, and functional for people.

Our portfolio has expanded to include new buildings and commercial work. We maintain our passion to transform our environment in the broader context, and to never be wasteful!

We, at G+S, place our clients’ needs first. We design a unique strategy around each project – taking into account the specifics of scope, site, budget and timeline. We are great listeners and we pay attention to the details. Our expertise allows us to shepherd a project through the complex world of planning approvals, permitting, bidding and construction.
