Turnbull Griffin Haesloop is an award-winning architecture firm in Berkeley, CA, led by Eric Haesloop FAIA.  We focus on sustainable, site sensitive designs of residential homes and consult on larger scale projects.

We continue William Turnbull’s commitment to creating buildings of enduring architectural value.  We believe architecture is primarily concerned with establishing a ‘sense of place’, inspired by the uniqueness of each site and each client.  We carefully listen to the aspirations and requirements of our clients and seek design solutions that layer site and program to build memorable places.

Since the concept for each of our buildings is rooted in its environment, we are particularly attentive to topography, microclimate, solar orientation, vegetation, water resources, and fire resilience.  Green building principles guide us, and we choose building materials that compliment and celebrate the setting.
