Floor Plans Walk-Through

Main Level

Bonus Room Over Garage

Basement Option with Main-Floor Stairs

Basement Level

Half Bath Option

3-Car Side Garage Option

2-Car Front Garage Option

The main level is engineered for efficient circulation and defined zoning. The split-bedroom layout keeps the primary suite on one wing and two secondary bedrooms on the other with a shared Jack-and-Jill bath between them: privacy, and also an acoustic separation from the great room. The central core combines great room, kitchen, and dining under 10-foot ceilings with a kitchen island that seats three. The mudroom-laundry service run from the garage is the strongest argument for this plan. You come in from the car, drop gear in lockers, laundry is immediately to your left, and the primary walk-in closet sits just on the other side of the laundry wall, entered from the primary bath. The optional bonus over the garage adds a full bath and up to 518 sq ft (the figure the plan gives with the 3-car garage option); useful as a fourth bedroom, guest suite, or away-room for older kids.

Exterior and Porch Character

The exterior is a well-balanced modern farmhouse composition with prominent gables. In the plan's rendering, white board-and-batten siding wraps the whole house, from the front-facing gable to the dormer above the porch, and square white posts carry a deep front porch that spans most of the elevation; the matching rear porch extends the great room outdoors in fair weather. Standing seam metal roofs over the porch, the bay window and the dormer contrast with the architectural asphalt shingles of the main roof. Black window sashes and a black front door run throughout, a small choice that does a lot of work to sharpen the white house against the surrounding pines.

Where Plan 51762HZ Works Well

The service circulation is laid out the right way. The mudroom-to-laundry run goes garage, lockers, laundry, kitchen without crossing the living room, which keeps wet coats, sports bags and grocery traffic out of the spaces where the family sits. The primary closet backs onto the laundry wall, so the walk from the closet to the washer is short, though it runs through the bedroom and the entry rather than through a direct door. The split-bedroom separation is genuine as well: the great room sits between the two bedroom wings, giving the primary suite real acoustic privacy instead of the thin-wall version common in this price range.

Volume and outdoor space are well judged for the footprint. The 10-ft great room ceilings read as generous at this size, and a tray or vaulted option would push the room further without tipping into McMansion territory. The front and rear covered porches (32-0 x 6-0 and 28-4 x 10-0) add roughly 475 sq ft of three-season usable space, which matters in any Southern climate. Above the garage, the bonus room is real square footage, up to 518 sq ft with the 3-car garage option, with its own full bath that converts usefully into a fourth bedroom, an in-law suite or a remote-work floor.

The plan also adapts to the lot without extra drafting. It comes with four foundation options (crawl, basement, basement with main-floor stair relocation, and slab), so most sites work without a custom redraw. Two garage orientations ship with the plan, a 2-car front-load option and a 3-car side-load that keeps the same width but pushes the depth of the house to 69 feet 6 inches, which saves a revision round with the architect.

Bonus Room and Code Details to Check

The first few items are about how the house lives. The Jack-and-Jill bath for the secondary bedrooms works well for siblings of similar age and is less popular with mixed teenagers or in rental scenarios, so add indicator privacy locks on both doors at a minimum. The open dining area has no formal separation; if a future buyer wants a walled dining room, the only options are a partial ceiling beam or a glazed partition, since a full wall would cut off the great-room light. The bonus room stair starts in the mudroom entry beside the garage door, so it stays indoors and conditioned, but guests heading up pass through the busiest service zone of the house. For a true guest suite, give that entry finishes and lighting that suit a front-of-house route.

The bonus room also raises mechanical and code questions. Mechanical zoning there is a second HVAC decision: a room over a garage gains and loses heat differently from the main house, so it needs its own thermostat or a mini-split sized per ACCA Manual J/S/D. Remind your builder that IRC R302.6 garage-to-dwelling fire separation calls for 5/8-inch Type X gypsum on the garage ceiling whenever living space sits above; it is not optional, and it still gets forgotten. Because the bonus is finished as habitable space, IRC R310 requires a compliant 5.7 sq ft egress window for any room used as a bedroom, and those windows should be specified at framing, not at finish.

Two more checks belong at permit stage. The primary bath is a five-piece layout but tight on aisle clearance: NKBA Planning Guidelines 5 and 6 call for 30-in clearance at the tub and 36-in at the vanity, so verify the plan dimensions at permit submittal. And the envelope specification matters more than the style specification. Whether you comply with IECC R402 prescriptively or by the Performance Path will dominate the cost variance between a budget build and a high-performance version of this plan, because insulation, blower-door target and window SHGC are where the money actually goes.

Proposed Facade Variations

The six facades below are styling concepts from our desk for Plan 51762HZ, not options sold by Architectural Designs. Each one keeps the plan's gables, porch and dormer exactly as drawn and changes only cladding, roofing and planting, so read them as starting points for a conversation with a builder.

Tudor Revival Influence

Smooth light stucco (Sto Cirritex in Cream) with dark decorative half-timbering in Benjamin Moore Soot 2129-20 on the gables and the dormer, carried down into dark timber porch posts with curved brackets. Roof in DaVinci Bellaforté Slate composite, with leaded-glass diamond-pattern sashes in every front window. Landscape reads formal: manicured Buxus sempervirens 'Green Velvet' hedges flanking a herringbone path of reclaimed Charleston brick, with 'Iceberg' white roses in beds. Suited to homeowners who appreciate European manor-house character and accept the extra upkeep that half-timbered exteriors demand.

Modern Monochromatic Scandinavian

A single-tone dark facade: James Hardie vertical panel and batten painted BM Soot 2129-20, Drexel Metals standing seam in Matte Black on the porch roof, the bay awning and the dormer above a dark shingle main roof, and Marvin Modern black-clad windows. Landscape is severely reduced: 3/8-in Black Mexican beach pebble ground cover, large 24x36 cast concrete pavers in an offset grid, and one big blue Agave americana beside a row of three narrow-leaved spiky accents as the only softening. Targets homeowners who want contemporary sculptural presence with low maintenance.

Mediterranean / Spanish Colonial

Warm smooth stucco in BM Shaker Beige HC-45 under a terracotta barrel-tile roof from Ludowici in Sienna Blend, with dark bronze standing seam awnings over the porch, the bay window and the dormer. The stucco carries through to the porch columns, while the dark-stained double front door and copper lanterns supply the wood and metal accents; copper gutters and downspouts would patina to a natural verde. The walk is 3/8-in decomposed granite in Sonoran Gold with brick steps, bordered by Lavandula 'Munstead' and rosemary 'Tuscan Blue'. Two 36-in terracotta planters from Campania Terra Lite hold Olea europaea 'Arbequina' at the front of the walk. Reads as southern European villa; best in drier climates.

Rustic Cedar Craftsman

Natural western red cedar shake, untreated so its fresh honey tone silvers with time, as primary cladding, with Montana Rockworks Chief Cliff ledgestone on the porch column bases. Roof is DaVinci Multi-Width Slate composite with Drexel standing seam accents in dark bronze over the porch, the bay window and the dormer. The landscape is lush and naturalistic: Pennsylvania flagstone path, dense mass planting of Polystichum acrostichoides Christmas fern, Hakonechloa macra 'Aureola', and Hydrangea paniculata 'Limelight'. Right choice for wooded lots.

Industrial Concrete & Metal

Equitone Tectiva fiber-cement panel in Natura Grey as primary cladding on the main gable block, with black board-and-batten on the porch wing and a Drexel standing seam roof in Dark Bronze over everything. The rendering paints the porch columns charcoal to match the siding; Cor-Ten columns (rated per ASCE 7 wind loads) on powder-coated steel bases are the rustier alternative. WAC InvisiLED integrated warm-white LED traces the gable roofline. Walkway is 24x48 cast concrete pavers in an offset grid over 3/8-in charcoal basalt gravel, planted with agaves, ornamental grasses and a few upright spiky accents. A true architectural-statement option for urban infill.

Coastal Cottage

Maibec pre-finished cedar shake in Seaglass Grey with crisp white trim in BM White Dove OC-17 on all casings, fascia, and columns. Drexel copper standing seam on the porch, bay and dormer awnings, left to patina to verde over 6–8 years. Path in crushed white oyster shell (Lowcountry-appropriate and locally sourced) bordered by 'Green Velvet' boxwood and massed white hydrangeas; blue Hydrangea macrophylla 'Endless Summer' in acidified soil is the alternative for anyone who wants blue flowers. A natural fit for Charleston, Savannah, and any Atlantic coastal lot.

Regional Cost and Fit

Each regional figure below rolls typical site work, the full build, basic landscaping and the plan purchase into one estimate for this house. The numbers are derived from 2025 RSMeans residential cost data with regional multipliers applied, and Charleston serves as the 1.00x reference because the facade concepts above were drawn for a Lowcountry lot.

Charleston, SC sets the baseline at 1.00x: about $540,000 at the standard tier and $720,000 at the premium tier. Close to the water, salt-air specifications add 4–6% to exterior finishes, a cost that lands hardest on the copper and cedar of the Coastal Cottage concept. Savannah, GA runs slightly cheaper at 0.94x, or $507,600 standard and $676,800 premium, with a similar climate and somewhat lower labor rates.

Atlanta, GA comes in at 0.95x ($513,000 standard, $684,000 premium). Its winters bring more freeze-thaw cycles than the coast, so upsize the roof underlayment, particularly where the shingle roof meets the metal porch and dormer roofs. Nashville, TN is good value at 0.91x, with allowances of $491,400 and $655,200, but it sits in IECC Zone 4, so check the plan's insulation R-values against that zone before ordering construction drawings.

Austin, TX is the costliest market on the list at 1.06x, or $572,400 standard and $763,200 premium, and TCEQ drought rules push the planting toward xeriscape, which favours the gravel-and-agave yards of the Scandinavian and Industrial concepts over the hydrangea borders of the Coastal Cottage. Asheville, NC lands at 0.97x ($523,800 and $698,400); sloped lots are common there and retaining walls add 6–10%, though the same slope is what makes the plan's basement foundation option worth pricing.

Raleigh-Durham, NC offers the best value of the seven markets at 0.89x, with a standard allowance of $480,600 and a premium allowance of $640,800, helped by a mild climate and a deep pool of building labor.

Frequently Asked Questions

Is 2,077 sq ft enough for a family of four?

In this plan, yes. The split layout, the full mudroom, and the generous great room read as larger than the footprint. If you add the bonus room (up to 518 sq ft with the 3-car garage) as a fourth bedroom or office, the home lives like a 2,600 sq ft plan without feeling oversized.

What does the optional bonus room add to the build cost?

Based on typical 2025 cost estimates, finishing the bonus (up to 518 sq ft) with a full bath adds $68,000–$92,000 on top of a shell cost. The variable is mostly mechanical: running a second HVAC zone or installing a mini-split, plus the full bath plumbing rough-in.

Is the Jack-and-Jill bath a resale concern?

Less than it used to be. Buyers with young children actively prefer it; buyers with teenagers often don't. It remains a common and accepted layout in family-oriented markets. Specify proper indicator privacy locks and it's a non-issue.

Can the plan drop the bonus room entirely?

Yes. The bonus is optional on the Architectural Designs plan set. Removing it saves the stair framing, the second zone of HVAC, and the full bath plumbing, typically $35,000–$55,000 off the build.

Which foundation option is best?

Depends on lot. In Charleston most builds are slab; Asheville and Nashville often walk-out basement; Atlanta and Austin are slab country. The plan ships with four options so you don't have to pay an architect for a custom redraw.

How does the primary suite compare to similar plans?

The short walk from the primary suite to the laundry is the differentiator. Among 2,000–2,200 sq ft farmhouse plans, this detail is far from standard, and it is one of the first details worth checking when comparing plans in this size band.

Which facade variation holds value best?

In Southeastern markets, the Coastal Cottage and Rustic Cedar Craftsman options are the safest choices because they match regional vernacular. The Industrial Concrete and Modern Monochromatic Scandinavian options work best in Austin and urban infill; they can be a harder resale in traditional farmhouse neighborhoods.

What should you ask the builder before bidding?

Three things: their IECC R402 compliance pathway (prescriptive vs. performance, blower-door target), whether they're including IRC R302.6 Type X gypsum at the bonus-over-garage, and whether they'll include ACCA Manual J, S, and D in the HVAC design scope. If those three answers come back clear, you've found the right builder.

Who Plan 51762HZ Suits

Plan 51762HZ is the kind of plan we would keep on a short list for anyone asking for "a sensible farmhouse that doesn't fight us." The split-bedroom layout, the mudroom-laundry service run, the laundry tucked behind the primary suite, and the two-orientation garage all read as carefully considered decisions. The Jack-and-Jill bath, the open dining, and the bonus stair rising out of the mudroom entry are genuine compromises. None of them are deal-breakers, and all of them are worth talking through with a builder before you frame.

If this plan is in the running for you, it's worth comparing to the single-story modern farmhouse review at a similar footprint, to the 2,085 sq ft split-bedroom blueprint for a direct size peer, to the smaller 1,677 sq ft vaulted-great-room plan if you're scaling down, and to the 2,866 sq ft split-bedroom analysis if you're scaling up.
