Our Services

We specialize in helping you create expanded living space, whether that's a second story addition, an Accessory Dwelling Unit (ADU), or backyard cottage. We're dedicated to delivering exceptional craftsmanship, beautiful, and livable spaces that meet your needs and exceed your expectations. Our team is committed to getting your project done on time and within your budget, always communicating effectively with you throughout the process.

Second Story Additions

Many Bay Area homeowners want to "trade up" to a bigger space, but realize that building a second story can be a cost-effective and creative solution. We've helped dozens of homeowners grow their homes as their families grow. We partner with you, your architect, and other team members to help you realize your vision for the space where you'll create countless memories.

ADUs - Accessory Dwelling Units

Also known as granny units, in-laws, or backyard cottages, ADUs can enhance your property value and enhance your lifestyle. Whether you want a space for your aging family member, an office, a guest cottage, art studio, or a separate rental unit, we can help you navigate the process from start to finish. Our team will coordinate the right experts for your project, from architects with ADU experience to lenders and engineers.

We're proud of our portfolio of projects, which showcase our commitment to excellence and attention to detail. From second story additions to ADU construction, our team has delivered stunning results that exceed our clients' expectations.
