The lowest-cost way to put a complete, permitted second home on your lot.
At 735 square feet, The Compact lives far bigger than its footprint: an open kitchen-living core, two real bedrooms, and a bath and a half — with zero hallway waste. It is the plan most owners choose for a first long-term rental or a parents' cottage.

Cold-formed steel frame, waterproof mineral-board shell, continuous insulation with triple-pane windows, instant hot water at every bath, room-by-room heat pumps, and solar-canopy + battery readiness. See how we build →
The Compact is $128,625, turn-key, at Arena's fixed $175 per square foot — design, permits, site work, and the full Arena Standard included. The price you see is the price you sign.
Wasatch Front comparables put The Compact around $1,400 per month as a long-term rental. Your Arena advisor prices your exact lot and neighborhood before you commit.
Arena homes are panelized cold-formed steel — cut in the factory, assembled on site in weeks, not the year-plus a stick build takes.
Yes. Every Arena home uses CAD-cut cold-formed steel framing with mineral-board (MgO) sheathing — non-combustible, and immune to rot, mold, warp, and termites.
