Ground-Up Home Addition

Residential Construction · West Jordan, UT · 2026 · 43 photos

A new living space built from the slab up beside an existing home — foundation, framing, roof, mechanical systems, drywall, flooring, a full bathroom, and a wood-cabinet kitchen. Follow the build stage by stage.

1. Foundation & floor system

The build starts on a poured concrete foundation, anchored with metal straps and topped with a subfloor deck — the flat, square base every later stage depends on.

2. Framing

Walls, window and door openings, and floor joists go up, with wall sheathing starting to close in the structure.

3. Sheathing & roof

The roof structure and wall sheathing turn the frame into a weather-tight shell, with the roofline and porch defined.

4. Mechanical, electrical & plumbing rough-in

Before any wall is closed, electrical wiring, HVAC ductwork and plumbing are run through the framing and trusses — the part of the job nobody sees later, and the part that determines how well the home works.

5. Weather barrier & exterior

Windows are set and the structure is wrapped in a weather-resistive barrier, keeping moisture out while the interior work continues.

6. Insulation & drywall

Insulation is installed and drywall hung to turn open framing into finished rooms, including the shower alcove.

7. Finishes: floors, paint, kitchen & bath

Wood-look flooring, paint, trim, interior doors, a wood-cabinet kitchen with an island, laundry hookups, and a tiled walk-in shower with a glass door. Then the yard goes back in.
