#14135 – 14x20x10 Urban Garage with Attached Lean-To in Spokane, WA

Steel Structures America built this 14′ × 20′ residential pole building in Spokane, WA. Compact yet highly functional, this project was designed to serve as a small garage or storage shop while maintaining a clean residential appearance.

Design & Layout

The main building measures 14′ × 20′ with a 10′ eave height and a 4/12 gable roof pitch. The crew attached a 22′ × 22′ single-slope lean-to to the main structure, adding extra covered space for equipment, vehicles, or flexible use. The overall layout balances utility with compact dimensions, making it well-suited for a residential setting.

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 it with fibermesh, and cut control joints for long-term durability.

The building includes:

• (1) 18′ × 8′ insulated overhead door
• (1) 12′ × 8′ insulated overhead door
• (1) 3′ × 6′8″ ArmorGuard walk-in door
• (1) 4′ × 3′ vinyl window for light and airflow

The overhead doors feature a contemporary raised-panel design with plain lite windows. SSA installed them in a contrasting color to create visual interest against the siding and roof.

The crew installed 2 ½″ fiberglass insulation in the roof and walls to regulate indoor temperatures. On the interior, they finished the south and east walls with drywall. The foundation includes Perma-Columns®, which keep all wood above grade for long-term strength.
