Plan HG-1590 (896 Sq Ft (28x32) 2 Bed 2 Bath Modular / Prefab Cottage Floor Plan) is an IRC R304/R310-vetted modular / prefab cottage blueprint engineered around a 32'-0" × 28'-0" structural grid (896 sq ft base footprint, 0.88:1 Square-Bay Proportion). Configured on the Consolidated Wet-Wall + Open Great Room topology, this layout delivers 896 sq ft of conditioned residential living area and 120 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 5 distinct architectural zones: PRIMARY SUITE (16'-6" × 12'-6", 206 sq ft), BEDROOM 2 (15'-6" × 12'-6", 194 sq ft), GREAT ROOM & DINING (20'-0" × 15'-6", 310 sq ft), BATH & LAUNDRY (12'-0" × 7'-0", 84 sq ft), KITCHEN & ISLAND (12'-0" × 8'-6", 102 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 206 sq ft; BEDROOM 2 at 194 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 32' clear-span width utilizes factory-engineered 2x6 modular box system w/ marriage wall bearing on 120 linear feet of 6" exterior wall framing (~138 framing studs/posts) and 95 linear feet of interior partitions. The 5:12 hinged 5:12 architectural shingle or metal gable roof requires approximately 1,087 sq ft of roofing material (12 roofing squares), while the stem wall crawlspace or full perimeter foundation pours at an estimated 18 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-1590

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 32x28 896 Sq Ft (28x32) 2 Bed 2 Bath Modular / Prefab Cottage Floor Plan (HG-1590)?

Based on current national residential construction data for modular / prefab cottage structures, the dried-in structural shell for Plan HG-1590 (896 sq ft base footprint) ranges from $38,000 to $48,500 ($44/sq ft baseline). A complete turnkey build—including the 18-yard concrete foundation, 95 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 896 sq ft of heated space—ranges from $134,000 to $164,000. 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 896 sq ft 2-bedroom layout?

Plan HG-1590 features 5 architecturally solved spaces inside its 32' × 28' footprint: PRIMARY SUITE (16'-6" × 12'-6", 206 sq ft), BEDROOM 2 (15'-6" × 12'-6", 194 sq ft), GREAT ROOM & DINING (20'-0" × 15'-6", 310 sq ft), BATH & LAUNDRY (12'-0" × 7'-0", 84 sq ft), KITCHEN & ISLAND (12'-0" × 8'-6", 102 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 32' × 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 32'-0" × 28'-0" structural grid (120 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).
