Plan HG-2520 (1,601 Sq Ft (40x40) 3 Bed 2 Bath Single-Story Ranch Floor Plan (Split-Bedroom Privacy Wing + Center Great Room)) is an IRC R304/R310-vetted single-story ranch blueprint engineered around a 40'-0" × 40'-0" structural grid (1,600 sq ft base footprint, 1:1 Square-Bay Proportion). Configured on the Split-Bedroom Privacy Wing + Center Great Room topology, this layout delivers 1,601 sq ft of conditioned residential living area and 119 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: PRIMARY SUITE (12'-0" × 24'-0", 288 sq ft), EN-SUITE BATH (12'-0" × 16'-0", 192 sq ft), KITCHEN & ISLAND (17'-0" × 17'-6", 298 sq ft), GREAT ROOM (17'-0" × 22'-6", 383 sq ft), BEDROOM 2 (11'-0" × 23'-0", 253 sq ft), HALL BATH (11'-0" × 17'-0", 187 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 288 sq ft; BEDROOM 2 at 253 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 40' clear-span width utilizes 2x6 conventional stick frame w/ prefabricated roof trusses bearing on 160 linear feet of 6" exterior wall framing (~172 framing studs/posts) and 144 linear feet of interior partitions. The 6:12 gable roof w/ covered front porch requires approximately 2,004 sq ft of roofing material (21 roofing squares), while the slab-on-grade, crawlspace, or full basement option pours at an estimated 29 cubic yards of 4,000-PSI concrete.

What are the exact room dimensions inside this 1,601 sq ft 3-bedroom layout?

Plan HG-2520 features 6 architecturally solved spaces inside its 40' × 40' footprint: PRIMARY SUITE (12'-0" × 24'-0", 288 sq ft), EN-SUITE BATH (12'-0" × 16'-0", 192 sq ft), KITCHEN & ISLAND (17'-0" × 17'-6", 298 sq ft), GREAT ROOM (17'-0" × 22'-6", 383 sq ft), BEDROOM 2 (11'-0" × 23'-0", 253 sq ft), HALL BATH (11'-0" × 17'-0", 187 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 40' × 40' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 40'-0" × 40'-0" structural grid (160 LF perimeter) with clear-span 6:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for 2x6 Conventional Stick Frame w/ Prefabricated Roof Trusses, conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
