Steel Structures America built this 14′ × 20′ post-frame garage in Spokane, WA for a couple who moved from Texas two years prior. The house was great — the garage was not. “Once we got settled in, decided to build a usable garage,” the owner said.
The project came with a real constraint. The lot sits in an older part of Spokane with limited space, and the original garage footprint was grandfathered in with a reduced setback. “In order to get it permitted, we had to put it on the same footprint as the original garage,” the owner explained. “That’s how we ended up with this design.”
A traditional contractor actually pointed them toward post-frame. “He said, if we do that type of footing, we are going to have to go with the 5-foot inset. He said, ‘I recommend you go with a pole building type structure.’ So that’s how we ended up with Steel Structures America.” It also came in under budget. “It was less expensive. So that was great.”
The main building measures 14′ × 20′ with a 10′ eave height and a 4/12 gable roof pitch. SSA attached a 22′ × 22′ single-slope lean-to to the main structure, adding covered space for equipment, vehicles, or flexible use. The layout balances utility with a compact footprint — well-suited for a residential lot with tight clearances.
SSA finished the exterior with 29-gauge steel siding and added 2′ enclosed soffits for ventilation. The team poured a smooth 4″ concrete slab, reinforced with fibermesh, and cut control joints for long-term durability. Inside, they finished the south and east walls with drywall and installed 2½″ fiberglass insulation in the roof and walls. The foundation uses Perma-Columns® to keep all wood above grade. “The construction process went smooth, great crew. They were very respectful,” the owner said.
