Architect collaboration
Bring your architect or use one of ours. We review drawings for constructibility, code compliance, and cost optimization before final design is locked.
Custom Home Builders Miami
A custom home, built without the chaos.
We work with your architect or bring one to the table — then handle program, permitting, construction, and close-out under one roof.
Why JMK for a custom home
Custom homes succeed or fail in pre-construction.
The horror stories homeowners tell about custom homes — runaway budgets, missed timelines, change orders that double the contract — almost always trace back to the same root cause: the project was priced before it was engineered.
JMK does it the other way. Before we sign a contract, we run a full structural and trade review of your architect's drawings. We coordinate with MEP engineers, surveyors, and the AHJ to surface every hidden cost. Only then do we deliver a quote you can trust — because you can't have predictability without engineered pre-construction.

Investment
What does a custom home cost in Miami?
Custom home pricing in Miami-Dade and Broward varies widely with lot conditions, finish level, and structural complexity. Honest ballpark ranges for ground-up new construction (excluding land):
- Builder-grade, conventional construction: $300–$400 per sq ft
- Custom design, mid-tier finishes: $450–$650 per sq ft
- Luxury custom, premium finishes, coastal conditions: $700–$1,200+ per sq ft
Waterfront lots, hurricane requirements, and high-end finishes drive the upper end. We give honest pre-construction estimates before contract — so you decide if and how to proceed.
