Plan HG-2660 (2,801 Sq Ft (40x70) 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 70'-0" × 40'-0" structural grid (2,800 sq ft base footprint, 0.57:1 Square-Bay Proportion). Configured on the Split-Bedroom Privacy Wing + Center Great Room topology, this layout delivers 2,801 sq ft of conditioned residential living area and 207 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: PRIMARY SUITE (21'-0" × 24'-0", 504 sq ft), EN-SUITE BATH (21'-0" × 16'-0", 336 sq ft), KITCHEN & ISLAND (29'-6" × 17'-6", 516 sq ft), GREAT ROOM (29'-6" × 22'-6", 664 sq ft), BEDROOM 2 (19'-6" × 23'-0", 449 sq ft), HALL BATH (19'-6" × 17'-0", 332 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 504 sq ft; BEDROOM 2 at 449 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 70' clear-span width utilizes 2x6 conventional stick frame w/ prefabricated roof trusses bearing on 220 linear feet of 6" exterior wall framing (~223 framing studs/posts) and 187 linear feet of interior partitions. The 6:12 gable roof w/ covered front porch requires approximately 3,506 sq ft of roofing material (36 roofing squares), while the slab-on-grade, crawlspace, or full basement option pours at an estimated 47 cubic yards of 4,000-PSI concrete.

What are the exact room dimensions inside this 2,801 sq ft 3-bedroom layout?

Plan HG-2660 features 6 architecturally solved spaces inside its 70' × 40' footprint: PRIMARY SUITE (21'-0" × 24'-0", 504 sq ft), EN-SUITE BATH (21'-0" × 16'-0", 336 sq ft), KITCHEN & ISLAND (29'-6" × 17'-6", 516 sq ft), GREAT ROOM (29'-6" × 22'-6", 664 sq ft), BEDROOM 2 (19'-6" × 23'-0", 449 sq ft), HALL BATH (19'-6" × 17'-0", 332 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 70' × 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 70'-0" × 40'-0" structural grid (220 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).
