Custom Home Building for St. Johns property owners

Good custom home building in St. Johns begins with an afternoon on the property. CR-210 and the Durbin Creek corridor both sit inside the area we cover in St. Johns. The properties we work on in St. Johns are mainly new subdivision homes, semi-custom builds and outdoor living additions.

Recently converted timber land, flat, with fill pads and engineered drainage on nearly every new plat. Durbin Creek and its wetland fingers cut through the area, setting conservation buffers that shape lot layout. Those two facts explain most of the difference between a St. Johns estimate and one from an hour inland.

What St. Johns homeowners run into

Building in St. Johns means building inside somebody else's plan. Recently converted timber land, flat, with fill pads and engineered drainage on nearly every new plat, and altering that grade for a custom footprint has consequences for the shared stormwater system. County permitting with wetland buffer and impervious-coverage limits enforced parcel by parcel — which in practice means the architectural committee sees your elevations before the county does, and their material and color requirements are frequently narrower than code.

There's a second thing worth knowing about building in St. Johns: some of the newest housing stock in the region, so the demand is additions, pools, lanais and shops rather than renovation. So what fits St. Johns is not automatically what fits the next community over.

The issuing office is St. Johns County Building Services. That gets checked on the first visit, not after plans are paid for.

Put together, that's why we won't quote custom home building in St. Johns from a phone call. The variables that decide the number are all on the property.

What actually drives the cost

We won't quote a number sight unseen. These are the factors that move it, so you can see where your project is likely to land before we ever walk the property.

Utility distance
Power, water and sewer runs are priced by the foot. A homesite four hundred feet off the road carries costs a road-frontage lot does not.
Specification level, not square footage
Cost per square foot is a useless planning number on custom work. The same footprint varies enormously by window package, roof material, ceiling detail and cabinetry.

On the ground in St. Johns.

We build custom and semi-custom homes on St. Johns lots where setbacks, impervious-coverage limits and design guidelines define the envelope. New subdivision homes, semi-custom builds and outdoor living additions surround most sites. The work is fitting genuine custom quality inside a framework that was written to keep everything looking similar.

Because we're based in Keystone Heights, St. Johns and its neighbors get worked together: Fruit Cove, Switzerland, Julington Creek and Nocatee are all on the same rounds.

Custom Home Building questions in St. Johns

Will my HOA in St. Johns approve a custom design?

Usually, within limits. County permitting with wetland buffer and impervious-coverage limits enforced parcel by parcel. We look at the specific covenants before design, because finding out at review that your roof material or window profile isn't on the approved list costs weeks. In St. Johns the committee approval is the real gate, not the building permit.

Why won't you quote custom home building in St. Johns without seeing the property?

Cost here tracks the conditions rather than a rate card. Durbin Creek and its wetland fingers cut through the area, setting conservation buffers that shape lot layout — which is exactly the kind of thing that decides scope in St. Johns. The site visit and the estimate are both free.

What's the permitting process for custom home building in St. Johns?

Yes for anything structural or involving systems. Permits come from St. Johns County Building Services, and there's a local wrinkle worth knowing: county permitting with wetland buffer and impervious-coverage limits enforced parcel by parcel. We handle the whole submittal.

When could you get out to look at a St. Johns property?

Quickly for the walkthrough — St. Johns is close enough to Keystone Heights that scheduling isn't the constraint. Permitting is, and we'll be straight with you about how long St. Johns County Building Services actually takes.

Do you actually travel to St. Johns?

Yes, regularly. We're based in Keystone Heights and St. Johns County is core territory for us; Fruit Cove, Switzerland and Julington Creek are all on the same routes. (352) 478-6112 gets you a site visit.

Are you licensed and insured?

Yes — Florida Certified Building Contractor CBC1265492, with general liability and workers' compensation coverage. We'll provide certificates on request.

What kind of warranty comes with the house?

A one-year workmanship warranty, with manufacturer warranties on materials and equipment passed through to you documented at closeout.
