Plan HG-1230 (616 Sq Ft (22x28) 2 Bed 1 Bath Garage with Loft / Apartment Above Floor Plan with Apartment Above) is an IRC R304/R310-vetted garage with loft / apartment above blueprint engineered around a 28'-0" × 22'-0" structural grid (616 sq ft base footprint, 0.79:1 Square-Bay Proportion). Configured on the Side-Vestibule Garage + Balcony Apartment topology, this layout delivers 814 sq ft of conditioned residential living area paired with a 418 sq ft fire-separated workshop/garage bay and 66 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 9 distinct architectural zones: 1-BAY GARAGE (19'-0" × 22'-0", 418 sq ft), UTILITY & GEAR (9'-0" × 10'-0", 90 sq ft), FOYER & STAIRS (9'-0" × 12'-0", 108 sq ft), PRIMARY SUITE (10'-6" × 10'-0", 105 sq ft), BEDROOM 2 (9'-0" × 10'-0", 90 sq ft), FULL BATH (8'-6" × 10'-0", 85 sq ft). Plumbing rough-ins are consolidated across UTILITY & GEAR, FULL BATH, KITCHEN & ISLAND to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY SUITE at 105 sq ft; BEDROOM 2 at 90 sq ft) are acoustically buffered from the primary living core and positioned on exterior elevations for code-compliant egress glazing.

From a builder takeoff standpoint, the 28' clear-span width utilizes 2x6 lower walls + 14" engineered wood i-joist floor system bearing on 100 linear feet of 6" exterior wall framing (~153 framing studs/posts) and 146 linear feet of interior partitions. The 8:12 dormered gable or gambrel roof (8:12 / 4:12 shed dormers) requires approximately 829 sq ft of roofing material (9 roofing squares), while the 6" reinforced garage slab w/ perimeter footings & apron pours at an estimated 16 cubic yards of 4,000-PSI concrete.

Use the interactive Regional Cost Multiplier on this page to adjust for your local labor market and owner-builder sweat equity.

What are the exact room dimensions inside this 814 sq ft 2-bedroom layout?

Plan HG-1230 features 9 architecturally solved spaces inside its 28' × 22' footprint: 1-BAY GARAGE (19'-0" × 22'-0", 418 sq ft), UTILITY & GEAR (9'-0" × 10'-0", 90 sq ft), FOYER & STAIRS (9'-0" × 12'-0", 108 sq ft), PRIMARY SUITE (10'-6" × 10'-0", 105 sq ft), BEDROOM 2 (9'-0" × 10'-0", 90 sq ft), FULL BATH (8'-6" × 10'-0", 85 sq ft), LIVING & DINING (11'-0" × 12'-0", 132 sq ft), KITCHEN & ISLAND (8'-0" × 12'-0", 96 sq ft), STAIR LANDING (9'-0" × 12'-0", 108 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 28' × 22' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 28'-0" × 22'-0" structural grid (100 LF perimeter) with clear-span 8:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for 2x6 Lower Walls + 14" Engineered Wood I-Joist Floor System, conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
