The CRS Difference.
We're not just builders — we're your single point of contact from first sketch to final walkthrough.
Design + Build
One team handles everything. No middlemen, no finger-pointing, no miscommunication. Your architect and builder work side-by-side.
No-Surprise Pricing
Transparent, fixed-price contracts. You know exactly what you'll pay before we break ground — no hidden fees, no cost creep.
Radical Communication
Weekly updates, a dedicated project manager, and a client portal to track every milestone. You'll never wonder "what's happening?"
Premium Materials
We use the same finishes and materials found in multi-million dollar custom homes — quartz counters, luxury vinyl plank, designer fixtures.

Choose from 10 architect-designed ADU plans — from cozy 400 SF studios to spacious 1,200 SF family suites.

Ready to Build Your Vision?
We start every project with a quick, no-pressure video call, not a high-pressure in-home sales appointment. Just a real conversation about your goals, your property, and what's possible.
How It Works
15-minute video call • No commitment • Expert advice
Pick a time that works for you using the calendar. We'll send you a video call invite and talk through your project goals, timeline, and budget from the comfort of your couch.
