Built for real people

Broad strokes when you're dreaming it up. Fine-tuned controls when you need them.

For homeowners

Building for family — with a guide, not guesswork.

Multigenerational housing, aging in place, space for your parents or kids. It shouldn't take a $300K leap of faith. Strata helps you plan with real numbers before you commit.

For first-time builders

Your first big build shouldn't start with guesswork.

In-law suite, rental income, first investment property — whatever's driving your ADU, you deserve real cost data and a clear plan, not a contractor's ballpark.

For ADU builders

You've built dozens. Now build smarter.

You know the work. Strata gives you AI-powered estimating, scheduling, and scope planning that scales with your pipeline — grounded in real project data.

Proprietary data points

Who built this

Strata was built by engineers who've worked on aerospace programs, billion-dollar construction projects, and enterprise software systems. We brought that rigor to residential construction because homeowners and builders deserve the same quality of planning tools.

Every estimate, every answer, every recommendation traces back to what real people actually paid and built — not benchmarks, not guesses.

“I built Strata for my mom. She wanted an ADU but didn't want to become a project manager. Deep expertise underneath, simplicity on top.”
