Every plan here can be adjusted, and we design and build fully custom ADUs across Santa Barbara and Ventura County. Start with a model you like, then we tailor the layout to your lot, your needs, and your budget.
SITE-BUILT, NOT PREFAB
Your ADU is poured, framed, and finished right on your property, on its own foundation, the same way a house is built. The result is a permanent structure that matches your home and holds its value.
Constructed like a traditional house, because it is one.
LONG TERM VALUE
A site-built one-bedroom ADU is a permanent addition to your property, not a temporary structure. It expands your square footage, adapts as your needs change, and adds lasting value to real estate you already own, in two of California’s strongest markets.
An investment that lives on your lot.
SANTA BARBARA + VENTURA COUNTY
The smaller plans fit where space is tight; the larger ones add room without going to two bedrooms. Every plan is fit to your lot rather than forced onto it.
One contract covers design, engineering, permitting, site work, and construction through final inspection. Real pricing, no hidden allowances.
A guest house, multigenerational living, a home office, or space for parents or adult children, each with its own kitchen, bath, and entrance.
