Plan HG-1933 (1,441 Sq Ft (30x48) 2 Bed 2 Bath Modular / Prefab Cottage Floor Plan) is an IRC R304/R310-vetted modular / prefab cottage blueprint engineered around a 48'-0" × 30'-0" structural grid (1,440 sq ft base footprint, 0.63:1 Square-Bay Proportion). Configured on the Consolidated Wet-Wall + Open Great Room topology, this layout delivers 1,441 sq ft of conditioned residential living area and 180 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 5 distinct architectural zones: PRIMARY SUITE (25'-0" × 13'-6", 338 sq ft), BEDROOM 2 (23'-0" × 13'-6", 311 sq ft), GREAT ROOM & DINING (30'-0" × 16'-6", 495 sq ft), BATH & LAUNDRY (18'-0" × 7'-6", 135 sq ft), KITCHEN & ISLAND (18'-0" × 9'-0", 162 sq ft). Plumbing rough-ins are consolidated across BATH & LAUNDRY, KITCHEN & ISLAND to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY SUITE at 338 sq ft; BEDROOM 2 at 311 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 48' clear-span width utilizes factory-engineered 2x6 modular box system w/ marriage wall bearing on 156 linear feet of 6" exterior wall framing (~169 framing studs/posts) and 125 linear feet of interior partitions. The 5:12 hinged 5:12 architectural shingle or metal gable roof requires approximately 1,747 sq ft of roofing material (20 roofing squares), while the stem wall crawlspace or full perimeter foundation pours at an estimated 27 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-1933

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 48x30 1,441 Sq Ft (30x48) 2 Bed 2 Bath Modular / Prefab Cottage Floor Plan (HG-1933)?

Based on current national residential construction data for modular / prefab cottage structures, the dried-in structural shell for Plan HG-1933 (1,440 sq ft base footprint) ranges from $60,500 to $77,500 ($44/sq ft baseline). A complete turnkey build—including the 27-yard concrete foundation, 125 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 1,441 sq ft of heated space—ranges from $216,000 to $263,000. 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 1,441 sq ft 2-bedroom layout?

Plan HG-1933 features 5 architecturally solved spaces inside its 48' × 30' footprint: PRIMARY SUITE (25'-0" × 13'-6", 338 sq ft), BEDROOM 2 (23'-0" × 13'-6", 311 sq ft), GREAT ROOM & DINING (30'-0" × 16'-6", 495 sq ft), BATH & LAUNDRY (18'-0" × 7'-6", 135 sq ft), KITCHEN & ISLAND (18'-0" × 9'-0", 162 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 48' × 30' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 48'-0" × 30'-0" structural grid (156 LF perimeter) with clear-span 5:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for Factory-Engineered 2x6 Modular Box System w/ Marriage Wall, conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
