Plan HG-1741 (1,345 Sq Ft (28x48) 3 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 48'-0" × 28'-0" structural grid (1,344 sq ft base footprint, 0.58:1 Square-Bay Proportion). Configured on the Drive-Through Carriage Loft + Primary Suite topology, this layout delivers 1,681 sq ft of conditioned residential living area paired with a 1,008 sq ft fire-separated workshop/garage bay and 126 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 9 distinct architectural zones: 1-BAY GARAGE (36'-0" × 28'-0", 1008 sq ft), UTILITY & GEAR (12'-0" × 12'-6", 150 sq ft), FOYER & STAIRS (12'-0" × 15'-6", 186 sq ft), PRIMARY SUITE (19'-6" × 13'-0", 254 sq ft), BEDROOM 2 (16'-6" × 13'-0", 215 sq ft), FULL BATH (12'-0" × 13'-0", 156 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 254 sq ft; BEDROOM 2 at 215 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 48' clear-span width utilizes 2x6 lower walls + 14" engineered wood i-joist floor system bearing on 152 linear feet of 6" exterior wall framing (~201 framing studs/posts) and 213 linear feet of interior partitions. The 8:12 dormered gable or gambrel roof (8:12 / 4:12 shed dormers) requires approximately 1,809 sq ft of roofing material (18 roofing squares), while the 6" reinforced garage slab w/ perimeter footings & apron pours at an estimated 32 cubic yards of 4,000-PSI concrete.

What are the exact room dimensions inside this 1,681 sq ft 3-bedroom layout?

Plan HG-1741 features 9 architecturally solved spaces inside its 48' × 28' footprint: 1-BAY GARAGE (36'-0" × 28'-0", 1008 sq ft), UTILITY & GEAR (12'-0" × 12'-6", 150 sq ft), FOYER & STAIRS (12'-0" × 15'-6", 186 sq ft), PRIMARY SUITE (19'-6" × 13'-0", 254 sq ft), BEDROOM 2 (16'-6" × 13'-0", 215 sq ft), FULL BATH (12'-0" × 13'-0", 156 sq ft), LIVING & DINING (21'-0" × 15'-0", 315 sq ft), KITCHEN & ISLAND (15'-0" × 15'-0", 225 sq ft), STAIR LANDING (12'-0" × 15'-0", 180 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 48' × 28' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 48'-0" × 28'-0" structural grid (152 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).
