Plan HG-1473 (832 Sq Ft (26x32) 2 Bed 2 Bath Backyard ADU / Granny Flat Floor Plan (Split-Bedroom Privacy Wing + Center Great Room)) is an IRC R304/R310-vetted backyard adu / granny flat blueprint engineered around a 32'-0" × 26'-0" structural grid (832 sq ft base footprint, 0.81:1 Square-Bay Proportion). Configured on the Split-Bedroom Privacy Wing + Center Great Room topology, this layout delivers 832 sq ft of conditioned residential living area and 95 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: PRIMARY SUITE (9'-6" × 15'-6", 147 sq ft), EN-SUITE BATH (9'-6" × 10'-6", 100 sq ft), KITCHEN & ISLAND (13'-6" × 11'-6", 155 sq ft), GREAT ROOM (13'-6" × 14'-6", 196 sq ft), BEDROOM 2 (9'-0" × 15'-0", 135 sq ft), HALL BATH (9'-0" × 11'-0", 99 sq ft). Plumbing rough-ins are consolidated across EN-SUITE BATH, KITCHEN & ISLAND, HALL BATH to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY SUITE at 147 sq ft; BEDROOM 2 at 135 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 32' clear-span width utilizes 2x6 dimensional lumber framing / panelized sip option bearing on 116 linear feet of 6" exterior wall framing (~135 framing studs/posts) and 102 linear feet of interior partitions. The 3:12 architectural standing-seam shed / low-slope gable requires approximately 961 sq ft of roofing material (11 roofing squares), while the stem wall or monolithic concrete slab-on-grade pours at an estimated 17 cubic yards of 4,000-PSI concrete.

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 832 sq ft 2-bedroom layout?

Plan HG-1473 features 6 architecturally solved spaces inside its 32' × 26' footprint: PRIMARY SUITE (9'-6" × 15'-6", 147 sq ft), EN-SUITE BATH (9'-6" × 10'-6", 100 sq ft), KITCHEN & ISLAND (13'-6" × 11'-6", 155 sq ft), GREAT ROOM (13'-6" × 14'-6", 196 sq ft), BEDROOM 2 (9'-0" × 15'-0", 135 sq ft), HALL BATH (9'-0" × 11'-0", 99 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 32' × 26' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 32'-0" × 26'-0" structural grid (116 LF perimeter) with clear-span 3:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for 2x6 Dimensional Lumber Framing / Panelized SIP Option, conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
