Floor Plan Walkthrough

The plan reads like a textbook exercise in efficient single-level zoning. Walk in through the covered front porch and you land in a short entry vestibule that opens sight-lines straight through the great room to the rear-facing sunroom position, a move that makes 1,504 sq ft feel materially larger than it is. The great room carries a cathedral ceiling, which should go to 14 feet at the ridge with a structural ridge beam rather than a collar-tie assembly, so the volume reads clean. Kitchen sits to the left at 12'0" x 9'0" with a working island, a pantry closet just off the drop zone, and a 12'0" x 10'2" dining room against the rear wall. The split-bedroom move is the real headline: the owner's suite takes the rear right corner while Br.2 sits at the front right, with the stair, the pocket office and the hall bath between them. Primary bath has dual vanities and a proper walk-in closet, with no compromises there. Secondary bedroom sits opposite, with its full bath and, critically, a small pocket office tucked off the hallway. That office is what pushes this plan past a “standard small ranch” into something genuinely livable for a remote-working couple. The mudroom off the 2-car garage handles laundry, boots, and coat storage in one footprint, which is the efficient way to handle it. The optional sunroom on the rear elevation is where the money is best spent: it converts the great room's visual depth into usable four-season square footage for about $28,000–$42,000 extra depending on glazing spec.

Exterior Read

The stock elevation does quite a bit of work for a modest footprint. Horizontal lap siding covers the main volume, board-and-batten fills the front gable under a small attic window and roof brackets, cultured stone wraps the short piers either side of the garage door, and a pergola with brackets shades the garage opening. The roof is drawn in shingles: a side-gable main roof at 6/12 with a steeper 10/12 front gable over the porch. It is plain craftsman vocabulary, used without fuss. The front porch is generous, roughly 20 feet wide with a 7-foot depth, framed by square columns standing on the porch deck. The front-loading garage sits to the left of the porch, so the porch, columns and gable have to carry the curb appeal at this scale. For a Charleston coastal lot, specify 8-inch James Hardie panel with battens to meet the HZ10 coastal exposure spec per James Hardie's regional engineering bulletin, and verify the roof pitch meets local wind uplift per ASCE 7-22. Everything else here translates cleanly.

What Plan 42733DB Does Well

The plan manages a lot within 1,504 sq ft. Split-bedroom zoning puts the owner's suite at the rear and Br.2 at the front of the right side, with the stair, the pocket office and the hall bath buffering sound between them. The cathedral-ceiling great room gives the central living zone a volume a footprint this size usually cannot afford. And the dedicated pocket office is the feature that turns this from a retirement cottage into a legitimate dual-income remote-work plan.

The daily-use spaces are efficient without being cramped. The front-loading 2-car garage sits to one side, so the covered porch still gives the elevation a residential read, and the mudroom-plus-laundry drop zone handles household traffic without crossing the living core. The kitchen island and pantry closet are efficient space planning at this square footage, not inflation, and the primary bath delivers the dual vanities and walk-in closet buyers expect.

Two outdoor features add real value. The covered front porch is roughly 7 feet deep, enough for a pair of rocking chairs and a small side table rather than a decorative sliver. The optional rear sunroom adds 180 sq ft of flex space without re-engineering the core slab, a rare upgrade that is genuinely optional.

Where 1,504 Sq Ft Gets Tight

The compromises of a small footprint show up in the shared rooms. The dining area is tight: comfortable for a 4-top round and strained past six seated, so for holiday entertaining plan to use the great room perimeter for buffet overflow. There is no secondary powder room either. Both bathrooms sit next to private suites, so guests share the hall bath in the secondary bedroom wing. Laundry lives inside the mudroom drop zone instead of a dedicated utility room, which works but is noisier than a closed-door laundry.

The office and the site impose their own limits. The pocket office is exactly that, roughly 8×7 feet of working space, and two simultaneous video calls will not work in it. The front-loading garage needs only a straight driveway, so the plan does not ask for the extra lot width a side-entry approach would. Finally, the cathedral-ceiling great room raises HVAC load in ACCA Manual J calculations, so size the system to the volume, not the square footage.

Facade Variations: Design Proposals

The six exteriors below are our editorial concept renderings of how the 1,504 sq ft shell could be re-clad for different regions and tastes; Architectural Designs does not sell any of them as elevation options. The plan set ships with only the stock craftsman front shown above, with its shingle roof, board-and-batten gable and garage pergola, so bring these to a builder or designer as a starting point for that conversation, not as drawings.

Stone & Shake Craftsman With Dry-Climate Planting

This is the closest of the six to the spirit of the stock elevation, suited to a Summerville or Kiawah buyer who wants the plan to sit quietly in a pine-and-live-oak setting. Tan Eldorado stone veneer wraps the whole front wall, garage included, cedar shake (real 18-inch Western red cedar, hand-split and R&R-graded, not the budget hybrid) fills the gable field, and the standing-seam roof is dark bronze to read warm against the stone. The porch columns stay simple: white PVC-wrapped 8×8 square posts standing on the porch deck, and the full-view garage door carries frosted glass in a bronze frame. The landscape goes drought-tolerant, with a decomposed-granite yard, softleaf yucca, agave parryi and Spanish lavender, plus two concrete planters flanking the driveway. Honest, unfussy, and it ages well: the shake silvers, the stone patinas, and the bronze roof is still the same color in thirty years.

Craftsman With Shed Dormer Accent

Same core palette as direction 1 but with a shed dormer set into the front roof plane over the garage. The dormer doesn't add interior space on this single-story plan, since it sits above the garage ceiling, but it breaks up the long roof and gives the front elevation more architectural incident. Size the dormer to roughly 14 feet wide; the brief calls for a pair of 4-over-1 craftsman windows, though the rendering simplifies them to plain divided casements, and the dormer cheeks are clad in the same shake as the gable. The porch posts change to dark bronze to match the roof. Landscaping stays dry-climate: blue fescue, yucca, agave and low succulents along the drive, with stepping pavers to the side yard. Best for neighborhoods where the base cottage would read as too quiet next to larger traditional two-story homes; the dormer gives it enough visual weight to hold its own on a mixed streetscape.

Modern Minimalist Stucco (Phoenix / Austin Hill Country)

Here the craftsman detailing comes off entirely and the shell gets re-skinned as a modern cottage. Romabio Classico Limewash over three-coat cement stucco per ASTM C926/C1063 in a soft warm white (think their “Avorio White” tone) covers the main body, dark gray vertical Hardie panel with 1/4-inch reveals fills the gable field, the roof is light-gray flat concrete tile, and the garage door is a flat-panel aluminum door painted white to disappear into the stucco under a slim black steel canopy. The front door flips to a dark vertical-grain walnut slab with a long black pull. The landscape is austere and deliberate: a concrete paver walkway, a single shallow reflecting pool at grade, three mature Agave americana specimens, and a backdrop of Mexican feather grass. This direction fits neatly into Austin Hill Country, Phoenix Arcadia, and Southern California canyon settings where modern minimalism is the dominant regional grammar.

White Modern Farmhouse

The high-volume direction for Nashville, Franklin, Greenville, and most of the Charlotte metro. White vertical board-and-batten (James Hardie HZ10 if coastal, smooth cementitious if inland) wraps the house, with black Marvin double-hung windows with 2-wide mullion grids in the upper sash, a black standing-seam metal roof, a black carriage-style garage door with four upper glass lites, and a dark stained timber pergola over the garage opening. The porch columns become dark-stained 8×8 square timber posts set on a brick porch and steps, with matching brackets in the gable. The landscape goes traditional and neat: clipped boxwood hedges, limelight hydrangeas at the porch corners, and a running-bond brick walkway in old Charleston red. Of the six, this is the most conservative choice for resale in these markets.

Contemporary Wood & Concrete

Warmer and more material-rich than the minimalist direction. The main body is warm-gray three-coat stucco (finished rough sand float), the gable field gets 1×4 vertical-grain Western red cedar laid horizontally and finished with a clear penetrating oil, the roof is a dark graphite slate-look shingle, and the garage door is a full-view aluminum unit with four rows of frosted glass lites. The porch railing swaps the traditional wood balustrade for a structural glass panel system in a dark frame, and the column bases get Eldorado ledgestone veneer, repeated on the piers beside the garage. The landscape is tiered and structural: low metal and concrete planters stepping down beside the lit porch stairs, Japanese forest grass spilling over the edges, a scatter of horsetail reed, and Ipe pavers on a 1/4-inch reveal. This one suits the Pacific Northwest, Asheville's creative-class neighborhoods, and select Atlanta infill where a craftsman that reads “contemporary but not cold” fits the street.

Eco-Rustic With Sedum Green Roof

Buyers who care specifically about sustainability, typically in Asheville, Boulder, Portland OR, or Burlington VT, are the audience for the sixth direction. Siding is full-thickness reclaimed Eastern white pine (real barn-board, not the printed panel product) laid vertically, oiled once with raw tung oil and left to silver. The main roof over the garage is dark-graphite standing seam carrying a photovoltaic array, which only makes sense if that slope faces south on your lot. The options are Tesla Solar Roof and standard Enphase-paired crystalline panels clamped to Englert seam; the clamped panels generally come out ahead on $/watt. The roof plane of the forward gable becomes an extensive sedum green roof assembly per the FLL Green Roof Guideline using the LiveRoof modular system, with a 4-inch growing medium and a drought-tolerant mix (Sedum album, S. kamtschaticum, Delosperma cooperi). The front door with its sidelites and the plank garage door both shift to vertical-grain cedar. The landscape is fully naturalistic: grass-filled permeable grid pavers for the drive and walk, native switchgrass, little bluestem, iris, echinacea, and black-eyed susan. Executing it correctly costs more than any other direction here, roughly $45,000 over the stock elevation for green-roof structural reinforcement, membrane, and plant establishment, so treat it as a values decision rather than a payback calculation.

Regional Fit Across Five Markets

How this plan translates across five markets: Charleston, Savannah, Nashville, Asheville, and the Texas Hill Country. Regional envelope, code modifications, and buyer appetite vary more than most plan shoppers realize.

In Charleston, Mount Pleasant and Kiawah, SC, the cottage scale and covered porch read as genuinely local, though infill lots in older neighborhoods such as Old Village may sit under design review, so check before you buy the plan. The coastal upgrades are specific: replace any shake with Hardie panel, verify wind-borne debris impact glazing in FEMA WZ mapped zones, raise the finish floor 12–18 inches above grade for NFIP compliance, and route crawlspace ventilation according to coastal best practice. Savannah, GA has strict historic district overlays, but outside the district the plan fits the midtown and Habersham streetscape cleanly. Deepen the front porch to 8 feet if the lot allows, and add a secondary screened porch at the rear for the evening mosquito season.

The inland and Texas markets push the style in different directions. In Nashville and Franklin, TN, buyers at this square footage tend to favor the white modern farmhouse look (facade variation 4), and a basement-level conditioning allowance makes sense because sloping Nashville lots can turn a walk-out basement into inexpensive square footage. In Asheville, NC, the eco-rustic direction (facade variation 6) and the contemporary wood & concrete direction (variation 5) both work; verify snow load per IRC Table R301.2(1), typically 30 psf in the Asheville basin and higher above 3,500 feet. In Austin, San Antonio and the Hill Country, TX, the modern minimalist stucco direction (variation 3) is the market fit, and the cathedral-ceiling glazing should face north where possible, because west-facing glass on an open Texas lot drives the cooling load up sharply.

2026 Build Cost Breakdown

The figures below price the stock craftsman elevation of Plan 42733DB in seven markets. They are our Q1 2026 editorial estimates built from typical subcontractor pricing rather than a construction-cost index, and each one covers the house turnkey from foundation to final punch list, leaving out land, bringing utilities to the site, and any landscaping beyond builder standard.

Median Turnkey Build Cost: Plan 42733DB (1,504 Sq Ft) $342,000 to $438,000 Regional spread, Q1 2026, stock craftsman elevation, excludes land and site work.

Charleston, SC (Mount Pleasant / West Ashley) comes in at $228 per square foot, which puts the turnkey build near $343,000 and a premium-tier finish near $412,000. Savannah, GA runs a little lower at $215 per square foot, or about $323,000 turnkey and $388,000 at the premium tier.

In Nashville, TN (Williamson Co.), the build rate per square foot is $252, the turnkey build allowance is $379,000, and the premium-tier allowance is $456,000. For Asheville, NC, the build rate per square foot is $244, the turnkey build allowance is $367,000, and the premium-tier allowance is $441,000.

In Austin, TX, the build rate per square foot is $241, the turnkey build allowance is $362,000, and the premium-tier allowance is $435,000. For Raleigh / Durham, NC, the build rate per square foot is $225, the turnkey build allowance is $338,000, and the premium-tier allowance is $407,000.

In Atlanta metro (inside Interstate 285), the build rate per square foot is $232, the turnkey build allowance is $349,000, and the premium-tier allowance is $418,000.

Line-item allocation at the $365,000 median.

The interior finishes and framing are the largest lines. Flooring, cabinets, trim, paint and tile run $48,000–$72,000, and the framing package of engineered lumber, a cathedral ridge beam and sheathing comes to $46,000–$58,000. The exterior skin of Hardie lap, board-and-batten, cultured stone piers, trim and paint adds $38,000–$52,000, and the foundation, either a monolithic slab or a crawlspace with vapor barrier and ventilation, costs $28,000–$38,000. Windows and doors in a Marvin Essential or Milgard Tuscany package run $24,000–$34,000, and the roof assembly, priced here as an Englert 24ga standing seam upgrade over the stock shingle roof with 30-lb underlayment and ice-and-water membrane, is $22,000–$31,000.

Systems are modest for a house this size. Plumbing rough and finish for 2 baths, the kitchen and laundry runs $22,000–$30,000; electrical, with 200-amp service per NEC 2023 Art. 230 and whole-house surge protection, $18,000–$26,000; and HVAC, a 15 SEER heat pump sized per Manual J to the cathedral volume, $14,000–$19,000. Insulation and air sealing to R-21 walls and R-49 cathedral per IECC 2021 R402 cost $9,000–$13,000, and appliances from builder-grade to mid-tier $8,000–$16,000.

Two options sit outside the base budget. The rear sunroom add-on costs an additional $28,000–$42,000, and the green-roof package from facade variation 6 adds $38,000–$48,000 over the stock roof.

Frequently Asked Questions

Is Plan 42733DB a good fit for empty-nesters planning to age in place?

Yes, with modifications. The single-level footprint, zero-step front porch entry potential, and primary suite with walk-in closet are already strong aging-in-place bones. For full aging-in-place readiness, specify: 36-inch clear door openings throughout, a curbless shower in the primary bath with a fold-down bench and grab bars roughed into the wall backing per ADA standard 4.26.3, lever-handle hardware site-wide, LED 2700K lighting at 30–40 footcandles in work zones, and a 36-inch-clear hallway at the primary-suite side. Budget roughly $14,000–$22,000 in upgrades over the stock specification to hit a true universal-design standard.

Will the cathedral ceiling in the great room drive energy costs up significantly?

It increases the conditioned volume by roughly 35–40% over a flat 9-foot ceiling across that same footprint, which translates to a modest HVAC oversize and a real increase in heating load. The fix is proper Manual J sizing per ACCA's standard, continuous R-49 insulation in the cathedral rafter bays (typically requires engineered wood joist or 2x12 framing with proper ventilation baffles per IRC R806), and high-performance windows. Done that way, the higher operating cost of a cathedral-ceiling great room in the Charleston climate is noticeable but not punishing.

Can the pocket office be converted into a small third bedroom?

Not and meet IRC 2021 R310 emergency escape and rescue opening requirements without modification. The pocket office as drawn is roughly 8×7 feet and has no code-compliant egress window. To legally call it a bedroom for appraisal and resale, you'd need to widen one wall to accept a 20-inch clear width × 24-inch clear height × 5.7 sq ft minimum egress opening with sill height no higher than 44 inches above finished floor. That's a possible modification but it will cost $6,000–$9,000 in framing/window/siding rework. As a bona-fide home office, guest room with a daybed, nursery for the early years, or remote-work studio it works as-drawn.

How does the optional sunroom tie into the main structure, and is it worth the money?

The sunroom is drawn as a rear-facing conditioned addition off the great room, adding 180 sq ft, with three glazed walls and a shed or low-slope roof tying under the main roof eave. Structurally it requires its own foundation (either extended slab or a matched crawlspace), its own HVAC zone or ductwork tap, and code-compliant door separation from the primary conditioned space per IECC 2021 R402. At $28,000–$42,000 extra it's the best flex-space dollar you can spend on this plan: it becomes a reading room, a sewing/hobby studio, a second office, or a plant room depending on the season. It is worth adding for most people who build this plan.

What's a realistic build timeline from foundation to certificate of occupancy?

At 1,504 sq ft, leaving out the basement the plan's stair leads down to and building on a standard crawlspace or slab foundation, budget 6.5 to 8.5 months from foundation pour to final CO. That assumes a stable permit turnaround, no weather delays beyond seasonal norms, a general contractor with a clean subcontractor book, and no custom finish callouts that add lead time (imported tile, specialty window orders, etc.). The single-story framing phase typically wraps in 4–5 weeks on this square footage.

Should this plan sit on a slab or a crawlspace foundation?

Regional. Texas, Arizona, and most of Florida: slab-on-grade with proper vapor barrier per IRC R506. Coastal Carolina, Georgia, and most of the Southeast where humidity and termite pressure are both high: conditioned crawlspace with a closed-cell spray foam underside of the subfloor and a sealed vapor-barrier ground cover per IRC R408. Appalachian and mid-Atlantic clay-soil regions with frost lines 24–36 inches deep: conditioned crawlspace is again the answer. Slab vs. crawl is a $6,000–$14,000 decision on this plan's footprint.

Does this plan work on a narrow city infill lot?

More easily than most ranches. The plan already draws a front-loading 2-car garage on a narrow footprint, so it needs no side driveway approach; check the overall width in the plan set against your lot's side setbacks before you buy.

How does the primary suite compare to plans at similar square footage?

Competitive. At 1,504 sq ft total, giving the primary suite a bedroom of 12'8"×13'0", a dual-vanity bath, and a proper walk-in closet is an efficient allocation. Many plans at this footprint downsize to a single-vanity primary bath and a reach-in closet to preserve other square footage. 42733DB doesn't make that compromise, which is part of why the secondary bedroom ends up being on the smaller side. The tradeoff reads reasonably for the target buyer.

A Cottage Ranch That Punches Above Its Size

Plan 42733DB is a quietly excellent small-footprint plan. Not flashy, not architecturally ambitious, but genuinely well-zoned for the empty-nester or dual-income-with-one-remote-worker buyer who's done with the four-bedroom colonial and ready to right-size without compromising the daily quality of the home. The split-bedroom separation, the pocket office, the cathedral-ceiling great room, and the optional sunroom together amount to a plan that punches above its 1,504 sq ft, which is exactly what a good cottage ranch should do.

To compare this against other single-story plans in the same square-footage bracket, our review of the 2,030 sq ft single-story craftsman plan is the closest sibling on the site: same architectural DNA, 526 sq ft more breathing room. For compact living specifically, our review of the efficient cottage duplex plan walks through another high-function-per-square-foot option. Readers drawn here by the home office should look at the expanded modern farmhouse plan with home office and flexible bonus space, the next size up, whose dedicated workspace is larger than the 8×7 pocket office in this plan. And for the split-bedroom idea at a larger scale, our functional analysis of the 2,866 sq ft split-bedroom modern farmhouse plan shows the same zoning move at nearly double the footprint.
