Plan HG-1328 (721 Sq Ft (24x30) 1 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 30'-0" × 24'-0" structural grid (720 sq ft base footprint, 0.8:1 Square-Bay Proportion). Configured on the Side-Vestibule Garage + Balcony Apartment topology, this layout delivers 937 sq ft of conditioned residential living area paired with a 504 sq ft fire-separated workshop/garage bay and 72 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 9 distinct architectural zones: 1-BAY GARAGE (21'-0" × 24'-0", 504 sq ft), UTILITY & GEAR (9'-0" × 11'-0", 99 sq ft), FOYER & STAIRS (9'-0" × 13'-0", 117 sq ft), PRIMARY SUITE (15'-6" × 11'-0", 171 sq ft), WALK-IN CLOSET (6'-0" × 11'-0", 66 sq ft), FULL BATH (8'-6" × 11'-0", 94 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 171 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 30' clear-span width utilizes 2x6 lower walls + 14" engineered wood i-joist floor system bearing on 108 linear feet of 6" exterior wall framing (~156 framing studs/posts) and 158 linear feet of interior partitions. The 8:12 dormered gable or gambrel roof (8:12 / 4:12 shed dormers) requires approximately 969 sq ft of roofing material (10 roofing squares), while the 6" reinforced garage slab w/ perimeter footings & apron pours at an estimated 18 cubic yards of 4,000-PSI concrete.

What are the exact room dimensions inside this 937 sq ft 1-bedroom layout?

Plan HG-1328 features 9 architecturally solved spaces inside its 30' × 24' footprint: 1-BAY GARAGE (21'-0" × 24'-0", 504 sq ft), UTILITY & GEAR (9'-0" × 11'-0", 99 sq ft), FOYER & STAIRS (9'-0" × 13'-0", 117 sq ft), PRIMARY SUITE (15'-6" × 11'-0", 171 sq ft), WALK-IN CLOSET (6'-0" × 11'-0", 66 sq ft), FULL BATH (8'-6" × 11'-0", 94 sq ft), LIVING & DINING (12'-0" × 13'-0", 156 sq ft), KITCHEN & ISLAND (9'-0" × 13'-0", 117 sq ft), STAIR LANDING (9'-0" × 13'-0", 117 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 30' × 24' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 30'-0" × 24'-0" structural grid (108 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).
