ARCHITECTURE
for the future of california

Designing a home is an incredible opportunity, let's ensure the results are extraordinary!  You want your home to be visually stunning, but will its performance match its appearance? If it’s designed and constructed to conventional standards, you’ll be disappointed. Compared to what’s now readily achievable, it will be prone to stale air, drafty, noisy, and only marginally comfortable despite high energy use. What’s more, if you follow the typical architectural approach, you risk cost and time overruns and ending up with a home that causes regret. You deserve more than mediocrity.

Great design is high-performance design. Your home should perform as well as it looks. With advanced architecture and conscientious construction, your home can be a sanctuary in the modern world – secure, comfortable, quiet, and rejuvenating. It will look great, feel great, and be an inspiring and healthy place for your family and our planet. We optimize our flagship projects to Passive House (Passivhaus), the world’s highest health, comfort, quiet, and efficiency standards. You could see 70-80% energy savings and never pay another power bill, even with car charging. Why settle for less?

State-of-the-art home performance isn’t an “add-on” or an afterthought, it’s woven in from the start. Your architect must be skilled, insightful, and experienced to achieve optimal performance in a cost-effective manner. Your builder must be at the top of their game too, and the entire team must be integrated and collaborative - excellent buildings are not accidental!

We’ve been at the forefront of high-performance architecture in California since 2008 – a quest to develop the world’s best homes. We’re passionate about exceptional design, coupled with rigorous attention to detail and unmatched technical expertise. In our practice, we “focus forward,” seeking what’s feasibly possible vs. merely adequate. Is this the standard of excellence you pursue in your own life? Let’s work together to handily achieve what conventional thinking regards as impossible.

Our approach is as innovative as our architecture - methodical, collaborative, and devised to maximize the joy and value of your home at an optimal budget. From the first meeting until your home is move-in ready, our responsive process fosters creativity, saves time, and minimizes uncertainty, stress, and cost overruns. We aim beyond custom design, to personalized design, for a home that’s uniquely yours. We take pride in creating homes that not only thrill but also amaze our clients.
