Plan HG-1556 (840 Sq Ft (28x30) 1 Bed 1 Bath Single-Story Ranch Floor Plan) is an IRC R304/R310-vetted single-story ranch blueprint engineered around a 30'-0" × 28'-0" structural grid (840 sq ft base footprint, 0.93:1 Square-Bay Proportion). Configured on the Consolidated Wet-Wall + Open Great Room topology, this layout delivers 840 sq ft of conditioned residential living area and 111 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 4 distinct architectural zones: PRIMARY BEDROOM (18'-6" × 12'-6", 231 sq ft), BATH & LAUNDRY (11'-6" × 12'-6", 144 sq ft), GREAT ROOM & DINING (18'-6" × 15'-6", 287 sq ft), KITCHEN & ISLAND (11'-6" × 15'-6", 178 sq ft). Plumbing rough-ins are consolidated across BATH & LAUNDRY, KITCHEN & ISLAND to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY BEDROOM at 231 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 30' clear-span width utilizes 2x6 conventional stick frame w/ prefabricated roof trusses bearing on 116 linear feet of 6" exterior wall framing (~135 framing studs/posts) and 84 linear feet of interior partitions. The 6:12 gable roof w/ covered front porch requires approximately 1,052 sq ft of roofing material (12 roofing squares), while the slab-on-grade, crawlspace, or full basement option pours at an estimated 17 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-1556

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 30x28 840 Sq Ft (28x30) 1 Bed 1 Bath Single-Story Ranch Floor Plan (HG-1556)?

Based on current national residential construction data for single-story ranch structures, the dried-in structural shell for Plan HG-1556 (840 sq ft base footprint) ranges from $34,000 to $43,500 ($42/sq ft baseline). A complete turnkey build—including the 17-yard concrete foundation, 84 linear feet of interior framing, MEP rough-ins for 1 bath(s), and interior finishes across 840 sq ft of heated space—ranges from $129,000 to $157,000. 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 840 sq ft 1-bedroom layout?

Plan HG-1556 features 4 architecturally solved spaces inside its 30' × 28' footprint: PRIMARY BEDROOM (18'-6" × 12'-6", 231 sq ft), BATH & LAUNDRY (11'-6" × 12'-6", 144 sq ft), GREAT ROOM & DINING (18'-6" × 15'-6", 287 sq ft), KITCHEN & ISLAND (11'-6" × 15'-6", 178 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 30' × 28' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 30'-0" × 28'-0" structural grid (116 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).
