Considered homes,
built as drawn.
SPX is a design·build firm for residential work that deserves restraint — new residences, whole-home renovations, and additions carried by one team from the first sketch to the final walk-through.
Most projects lose their design between the drawing and the jobsite. We removed the distance — the people who design the work stand next to the people who build it.
Six disciplines. One hand.
Design · Build Delivery
One team from first sketch to final walk-through — design, engineering, budget, and build under a single roof.
New Custom Residences
Ground-up homes built the way they were drawn — quietly, precisely, on schedule.
Whole-Home Renovations
Structural reconfigurations that make an existing house live like it was designed this decade.
Additions & Second Stories
Expansions that read like original construction — from footings to matched rooflines.
Lower Levels & Walkouts
Daylight lower levels — theaters, wine rooms, guest suites, and engineered walkout entrances.
Garages, Structures & Site
Detached garages, pavilions, and structural site work — slab to roofline, drawn and delivered.
The scopes other firms decline.
Opening a foundation for a daylight walkout. Carrying a second story over an occupied home. Removing the wall every other bid tiptoed around. Structural work is where design either survives or surrenders — so we kept it in-house, engineered, and self-performed.
Lower levels & walkouts- Engineered
- Stamped structural engineering on every cut, beam, and load path — drawn before demolition, not after.
- Self-performed
- Concrete, framing, and finish carpentry by our own crews; trade partners work to our schedule and standard.
- Documented
- Permitted, inspected, photographed — a record of what lives inside the walls, delivered at close-out.
SPX is the residential design·build practice of a Utah construction family with two decades on the Wasatch Front — a Spravek company, alongside Alpine Fence & Deck and Harlow Landscapes.
We take on a deliberate number of projects at a time. Each carries a principal’s attention, an engineer’s stamp, and a schedule that is kept quietly, without drama.
