1,152 Sq Ft (32x36) 3 Bed 2 Bath Backyard ADU / Granny Flat Floor Plan (Split-Bedroom Privacy Wing + Center Great Room)

Plan HG-2072 (1,152 Sq Ft (32x36) 3 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 36'-0" × 32'-0" structural grid (1,152 sq ft base footprint, 0.89:1 Square-Bay Proportion). Configured on the Split-Bedroom Privacy Wing + Center Great Room topology, this layout delivers 1,152 sq ft of conditioned residential living area and 105 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: PRIMARY SUITE (11'-0" × 19'-0", 209 sq ft), EN-SUITE BATH (11'-0" × 13'-0", 143 sq ft), KITCHEN & ISLAND (15'-0" × 14'-0", 210 sq ft), GREAT ROOM (15'-0" × 18'-0", 270 sq ft), BEDROOM 2 (10'-0" × 18'-6", 185 sq ft), HALL BATH (10'-0" × 13'-6", 135 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 209 sq ft; BEDROOM 2 at 185 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 36' clear-span width utilizes 2x6 dimensional lumber framing / panelized sip option bearing on 136 linear feet of 6" exterior wall framing (~152 framing studs/posts) and 121 linear feet of interior partitions. The 3:12 architectural standing-seam shed / low-slope gable requires approximately 1,330 sq ft of roofing material (15 roofing squares), while the stem wall or monolithic concrete slab-on-grade pours at an estimated 22 cubic yards of 4,000-PSI concrete.
