How it works
A build you can follow week by week
Clear phases, a schedule you can see and a project manager who answers the phone.
01
Discovery & feasibility
We visit the lot or the house, talk through your wish list and confirm zoning, budget and timeline.
02
Design & fixed price
Plans, engineering and selections are developed together, then priced into one fixed contract.
03
Construction
Our own project manager runs the build, with weekly photo reports and a schedule you can check any time.
04
Walkthrough & warranty
A detailed final walkthrough, a clean handover binder and a warranty team that keeps answering.
Design-build, in-houseAbout Northhaven
A builder that draws first, so nothing is guessed on site
Northhaven grew out of a frustration with the usual way homes get built: an architect here, a contractor there and the owner caught in between. We put design and construction in one office and one contract.
Every project has a fixed price, a written schedule and a named project manager. That is not a slogan — it is how the paperwork is structured.
- Florida-certified building contractor, fully insured
- Fixed-price contracts with written allowances
- Weekly progress reports with site photos
Good to know
Questions, answered
How long does a custom home take?
Design and permitting typically take four to six months; construction eight to twelve months depending on size and site. You receive a schedule before signing.
Can you work with plans we already have?
Yes. We review them for buildability and cost, price them, and can adjust details with the original designer or in-house.
Do you offer fixed pricing?
Every contract is fixed-price with written allowances for selections, so you know the number before the first shovel.
Which areas do you serve?
Tampa Bay and Central Florida — Hillsborough, Pinellas, Pasco, Polk and neighbouring counties.
