Plan HG-2147 (1,408 Sq Ft (32x44) 3 Bed 2 Bath Duplex / Multi-Gen Floor Plan) is an IRC R304/R310-vetted duplex / multi-gen blueprint engineered around a 44'-0" × 32'-0" structural grid (1,408 sq ft base footprint, 0.73:1 Square-Bay Proportion). Configured on the STC-60 Mirrored Acoustic Party-Wall Duplex topology, this layout delivers 1,408 sq ft of conditioned residential living area and 264 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 8 distinct architectural zones: UNIT A SUITE (13'-6" × 14'-6", 196 sq ft), UNIT A BATH (8'-6" × 14'-6", 123 sq ft), UNIT A LIVING (13'-6" × 17'-6", 236 sq ft), UNIT A KITCHEN (8'-6" × 17'-6", 149 sq ft), UNIT B BATH (8'-6" × 14'-6", 123 sq ft), UNIT B SUITE (13'-6" × 14'-6", 196 sq ft). Plumbing rough-ins are consolidated across UNIT A BATH, UNIT A KITCHEN, UNIT B BATH, UNIT B KITCHEN to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (UNIT A SUITE at 196 sq ft; UNIT B SUITE at 196 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 44' clear-span width utilizes 2x6 exterior + double-stud insulated acoustic party wall bearing on 152 linear feet of 6" exterior wall framing (~169 framing studs/posts) and 156 linear feet of interior partitions. The 5:12 architectural shingle or standing seam metal hip/gable requires approximately 1,708 sq ft of roofing material (20 roofing squares), while the monolithic concrete slab w/ dual sewer/water stub-outs pours at an estimated 26 cubic yards of 4,000-PSI concrete.

A complete turnkey build—including the 26-yard concrete foundation, 156 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 1,408 sq ft of heated space—ranges from $210,000 to $256,000. 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 1,408 sq ft 3-bedroom layout?

Plan HG-2147 features 8 architecturally solved spaces inside its 44' × 32' footprint: UNIT A SUITE (13'-6" × 14'-6", 196 sq ft), UNIT A BATH (8'-6" × 14'-6", 123 sq ft), UNIT A LIVING (13'-6" × 17'-6", 236 sq ft), UNIT A KITCHEN (8'-6" × 17'-6", 149 sq ft), UNIT B BATH (8'-6" × 14'-6", 123 sq ft), UNIT B SUITE (13'-6" × 14'-6", 196 sq ft), UNIT B KITCHEN (8'-6" × 17'-6", 149 sq ft), UNIT B LIVING (13'-6" × 17'-6", 236 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 44' × 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 44'-0" × 32'-0" structural grid (152 LF perimeter) with clear-span 5:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for 2x6 Exterior + Double-Stud Insulated Acoustic Party Wall, conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
