Start With the Lot

Before design, we look at what the parcel actually allows: zoning and FAR, height limits, setbacks, hillside ordinance, fire-severity zone, soils, and whether utilities are at the street. It's cheaper to find out now than after plans are drawn.

Zoning, FAR and height analysis
Soils and geotechnical reports
Hillside ordinance and grading review
Utility availability and connection costs
SB9 eligibility for lot splits

How We Keep It Predictable

Design-build means the people who drew it are accountable for building it on budget, with no finger-pointing between an outside architect and the builder when something doesn't fit. You get a fixed-price proposal with specifications and a milestone schedule you can track in your portal.
