How it works — from discovery to keys in hand.
A transparent, milestone-driven workflow. Every step is documented, every cost is visible, every decision is yours. Here's the exact blueprint we follow for every client.
A milestone for every decision.
No vague 'we'll see' phases. Each step has a defined duration, an owner, deliverables, and a gate you sign off on before we move.
Discovery call
A 45-minute conversation. Goals, lifestyle, budget envelope, timing. We leave with a one-page brief — or politely tell you we're not the right fit.
- Client brief
- Fit assessment
- Indicative budget range
Site & feasibility
We walk the lot (or shortlist 3–5 lots), pull zoning, FEMA flood, soil, and utility data, then model what's actually buildable and what it will cost.
- Site report
- Zoning & setback analysis
- Cost-to-build model
Design & selections
Architecture, interiors, and landscape developed in parallel. You see 3D walk-throughs every 2 weeks and approve a locked selections binder before we break ground.
- Schematic + DD drawings
- 3D walk-through
- Selections binder
Permits & contracts
We handle municipal submittals, HOA approvals, and lender coordination. You sign a fixed-fee construction contract with a transparent schedule of values.
- Building permits
- Construction contract
- Insurance binders
Construction
Weekly site reports with photos, schedule variance, and budget burn-down. Owner portal shows every invoice, every RFI, every change in real time.
- Weekly progress report
- Live owner portal
- Quality inspections
Punch & handover
Independent third-party inspection, full punch list, systems orientation, and warranty walk-through. You get the keys, the manuals, and a 12-month service plan.
- Third-party inspection
- Punch closeout
- Owner manual
Ongoing stewardship
Optional concierge: rental program enrollment, maintenance, insurance reviews, and resale strategy. Most owners stay with us long after move-in.
