Design Philosophy


We see architecture as an art form, a way to bring more richness to our lives. A space is the medium through which we bring natural light, views of the outside world, balanced spaces, proportionate details and pleasing colors into an environment.


The best designs are the ones that don’t require the builders to do extra work or the homeowners to alter their lives. Nearly all projects have this kind of latent design solution and we see it as our job to find it.


With creative use of low-cost, durable materials and the preservation of existing infrastructures, BOA will help you make the most of your investment.


Quality design and construction meant to endure constitute a valuable aspect of sustainable design. By combining beauty, function and durability in a project or remodel, BOA strives to exceed the California Energy Code.
