The Investor Triplex
Three doors on one foundation — the fastest house-hack in Utah.
The Investor Triplex is three self-contained units totaling 2,205 square feet. Live in one and rent two, or run all three as rentals. One build, one loan, three rent checks — the classic house-hack, engineered to Arena's fixed price.
Every plan ships with the full Arena Standard
Cold-formed steel frame, waterproof MgO floors, a continuous-insulation envelope with high-performance windows, pocket doors throughout, a rooftop deck, instant hot water at every bath, all-ductless heat pumps, and in-house solar + battery. See the full Arena Standard →
Inside every Arena home
The floorplan changes; the craft doesn't. Every Arena home is finished with the same engineered interior — designed once, perfectly, and built the same way every time.
The one-day kitchen
A chef's kitchen engineered to the inch and set in a single day — a quartz run with all-drawer storage, an induction island with a hood that clears to the outside, a built-in wall oven and a floor-to-ceiling pantry. All-electric, all built-in, no gimmicks.
Hotel-grade, spa-simple baths
Large-format tile and seamless stone shower panels that wipe clean in seconds — no grout lines to scrub — with matte-black fixtures on an engineered wet wall that's built faster and leaks less.
Bedrooms that store like a yacht
A built-in bed with storage underneath, a full-wall closet, and shelving on both sides — the smartest small-space design on earth, so a calm, compact room holds more than a bloated one ever will.
A steel stair you can move a couch up
A steel stair over 42 inches wide — one vertical spine connecting the garage, every floor, and the rooftop — with engineered storage tucked into the space underneath instead of wasted on air.
A rooftop deck, standard
A warm, protected roof built as 700+ square feet of outdoor living: a solar canopy overhead, room for an outdoor kitchen or a garden, and provisions for a hot tub and dry sauna.

How long does the build take?
Arena homes are panelized cold-formed steel — cut in the factory, assembled on site in weeks, not the year-plus a stick build takes.
Is it really steel-framed?
Yes. Every Arena home uses CAD-cut cold-formed steel framing with waterproof MgO board floors — non-combustible, and immune to rot, mold, warp, and termites.
