Plan HG-2122 (1,280 Sq Ft (32x40) 2 Bed 2 Bath Garage with Loft / Apartment Above Floor Plan with Apartment Above (Drive-Through Carriage Loft + Primary Suite)) is an IRC R304/R310-vetted garage with loft / apartment above blueprint engineered around a 40'-0" × 32'-0" structural grid (1,280 sq ft base footprint, 0.8:1 Square-Bay Proportion). Configured on the Drive-Through Carriage Loft + Primary Suite topology, this layout delivers 1,600 sq ft of conditioned residential living area paired with a 960 sq ft fire-separated workshop/garage bay and 105 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 9 distinct architectural zones: 1-BAY GARAGE (30'-0" × 32'-0", 960 sq ft), UTILITY & GEAR (10'-0" × 14'-6", 145 sq ft), FOYER & STAIRS (10'-0" × 17'-6", 175 sq ft), PRIMARY SUITE (16'-0" × 14'-6", 232 sq ft), BEDROOM 2 (14'-0" × 14'-6", 203 sq ft), FULL BATH (10'-0" × 14'-6", 145 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 232 sq ft; BEDROOM 2 at 203 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 40' clear-span width utilizes 2x6 lower walls + 14" engineered wood i-joist floor system bearing on 144 linear feet of 6" exterior wall framing (~190 framing studs/posts) and 209 linear feet of interior partitions. The 8:12 dormered gable or gambrel roof (8:12 / 4:12 shed dormers) requires approximately 1,723 sq ft of roofing material (17 roofing squares), while the 6" reinforced garage slab w/ perimeter footings & apron pours at an estimated 30 cubic yards of 4,000-PSI concrete.

What are the exact room dimensions inside this 1,600 sq ft 2-bedroom layout?

Plan HG-2122 features 9 architecturally solved spaces inside its 40' × 32' footprint: 1-BAY GARAGE (30'-0" × 32'-0", 960 sq ft), UTILITY & GEAR (10'-0" × 14'-6", 145 sq ft), FOYER & STAIRS (10'-0" × 17'-6", 175 sq ft), PRIMARY SUITE (16'-0" × 14'-6", 232 sq ft), BEDROOM 2 (14'-0" × 14'-6", 203 sq ft), FULL BATH (10'-0" × 14'-6", 145 sq ft), LIVING & DINING (17'-6" × 17'-6", 306 sq ft), KITCHEN & ISLAND (12'-6" × 17'-6", 219 sq ft), STAIR LANDING (10'-0" × 17'-6", 175 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 40' × 32' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 40'-0" × 32'-0" structural grid (144 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).
