Questions
What architectural styles do you specialize in?
We focus on modern, site-responsive designs that emerge organically from environmental context rather than applying predefined styles. Our work emphasizes spatial flow, natural material integration, and functional innovation.
Do you handle both design and construction phases?
We provide full-service architectural design including construction documentation. While we don't build projects directly, we maintain close coordination with contractors throughout the building process to ensure design integrity.
How do you incorporate sustainability into projects?
Sustainability guides our material selection, spatial planning, and systems integration. We prioritize passive solar design, energy-efficient building envelopes, and locally sourced materials to minimize environmental impact while optimizing long-term performance.
What areas do you primarily work in?
Our practice focuses on California's Bay Area including Los Gatos, Palo Alto, Monte Sereno, and surrounding communities where we've completed numerous residential transformations and new constructions.
Can you work with existing home designs?
Yes, we specialize in remodel-additions that modernize traditional homes while respecting original structures. Our approach transforms spatial limitations into opportunities for improved functionality and contemporary aesthetics.
How do you handle project budget constraints?
We work collaboratively with clients to establish realistic budgets early in design. Our process explores cost-effective material applications and construction methods that maintain design quality while meeting financial parameters.
