Plan HG-1974 (1,500 Sq Ft (30x50) 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 50'-0" × 30'-0" structural grid (1,500 sq ft base footprint, 0.6:1 Square-Bay Proportion). Configured on the Drive-Through Carriage Loft + Primary Suite topology, this layout delivers 1,875 sq ft of conditioned residential living area paired with a 1,125 sq ft fire-separated workshop/garage bay and 132 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 9 distinct architectural zones: 1-BAY GARAGE (37'-6" × 30'-0", 1125 sq ft), UTILITY & GEAR (12'-6" × 13'-6", 169 sq ft), FOYER & STAIRS (12'-6" × 16'-6", 206 sq ft), PRIMARY SUITE (20'-6" × 14'-0", 287 sq ft), BEDROOM 2 (17'-0" × 14'-0", 238 sq ft), FULL BATH (12'-6" × 14'-0", 175 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 287 sq ft; BEDROOM 2 at 238 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 50' clear-span width utilizes 2x6 lower walls + 14" engineered wood i-joist floor system bearing on 160 linear feet of 6" exterior wall framing (~208 framing studs/posts) and 225 linear feet of interior partitions. The 8:12 dormered gable or gambrel roof (8:12 / 4:12 shed dormers) requires approximately 2,019 sq ft of roofing material (20 roofing squares), while the 6" reinforced garage slab w/ perimeter footings & apron pours at an estimated 35 cubic yards of 4,000-PSI concrete.

What are the exact room dimensions inside this 1,875 sq ft 2-bedroom layout?

Plan HG-1974 features 9 architecturally solved spaces inside its 50' × 30' footprint: 1-BAY GARAGE (37'-6" × 30'-0", 1125 sq ft), UTILITY & GEAR (12'-6" × 13'-6", 169 sq ft), FOYER & STAIRS (12'-6" × 16'-6", 206 sq ft), PRIMARY SUITE (20'-6" × 14'-0", 287 sq ft), BEDROOM 2 (17'-0" × 14'-0", 238 sq ft), FULL BATH (12'-6" × 14'-0", 175 sq ft), LIVING & DINING (22'-0" × 16'-0", 352 sq ft), KITCHEN & ISLAND (15'-6" × 16'-0", 248 sq ft), STAIR LANDING (12'-6" × 16'-0", 200 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 50' × 30' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 50'-0" × 30'-0" structural grid (160 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).
