This is one of the more flexible 1,715-square-foot single-story plans we have reviewed this season. As designed, the main level is a complete one-bedroom home with a vaulted great room, a generous kitchen island, a private primary suite, and a three-car garage. The interesting part is what the publisher built into the structure: an optional bonus room above the garage, plus a fully framed basement option that can finish out as a recreation space, wet bar, two extra bedrooms, and two full baths. That gives you a clean path from one bedroom to four without ever changing footprint, which is rare for plans in this size band, and exactly the kind of layered flexibility that suits buyers who want to start small and grow into the house.

Main Level

Upper Bonus Level

Optional Basement Stairs

Optionally Finished Basement

The main level is built around a vaulted great room (10 feet rising to 15'-3") that opens directly into the kitchen and dining zone, which sit under flat 9'-1" ceilings: one continuous gathering space where the ceiling change marks the zones without blocking the sightline. The 15'-4" by 12'-0" kitchen lands a large quarter-round island with the sink and dishwasher, which suits households that actually cook for company (the island doubles as buffet runway), though storage beyond the cabinets is limited to a small closet by the refrigerator. The primary suite tucks into the right wing with its own vaulted ceiling, a well-laid-out bath, and a walk-in closet that's properly sized rather than token. On the opposite side, a compact study sits near the entry. It is small, but workable for a single-monitor home office or library nook. Practical zones are handled with a real 9'-2" by 8'-9" laundry room right at the garage entry, which doubles as the drop zone, worth looking for in single-story plans this size. The 32'-10" covered front porch and the 15'-0" by 10'-0" rear covered deck (flanked by uncovered deck wings) give you the kind of indoor-outdoor flow that works year-round across Southern coastal markets. The flexibility move is structural: the publisher built the framing for an optional staircase that goes either up to a bonus room over the garage or down to a basement, and the basement can be finished into a recreation room, wet bar, two more bedrooms, and two full baths, which together with the bonus room pushes the home from one bedroom all the way to four.
Exterior Elevations

The exterior reads as textbook contemporary modern farmhouse: white board-and-batten as the primary skin, a dark shingle main roof, standing-seam metal over the front porch and the small awnings above the garage and the right-hand window, and timber posts with knee braces at the porch that warm up the otherwise crisp white envelope. Three small gabled dormers break the long roof expanse, which matters on a single-story footprint this wide; without them the elevation would feel low and stretched. The three-car garage is a dominant front mass, and the design balances it with the tall gable over the double bay and the gabled wing at the opposite end. The rear elevation keeps the clean front lines but pushes more glazing, with large windows across the great room and primary suite walls to make the most of light and views toward the back lot. From a styling perspective, this is a starting palette that can be layered in any direction (eight of them are covered further down).








Pros & Cons
Pros
The strongest argument for this plan is its real expansion path from 1 to 4 bedrooms without ever changing the footprint, which is rare in this size class. It also delivers true main-level living, with the primary suite, laundry, kitchen and great room all on one floor, the arrangement that makes long-term aging-in-place practical.
Height does a lot of the work. Vaulted ceilings over both the great room and the primary suite make the 1,715 sf feel bigger than its number, and the covered porch along the front and the covered deck at the back add outdoor rooms for the morning and the evening.
Two less obvious strengths round it out. The three-car garage with the laundry at its entry door is over-built for a 1,715 sf plan in the best way, since storage is the thing most often retrofitted later and this plan handles it from day one. And the primary suite sits apart from the study and the garage entrance, which gives it the acoustic privacy most one-story plans miss.
Where This Plan Asks for Compromise
The biggest compromise is in the headline itself. As built, without finishing the basement or bonus room, the plan offers only one bedroom, which is not workable for buyers who need extra bedrooms on day one. The bonus room and basement options also add substantial budget on top of the heated-sf build cost, so the "1 to 4 bedroom flexibility" only delivers if you are prepared to fund the finish-out.
The study is compact and sits close to the front entry and the garage flow. It works as a library or a one-monitor desk, but it is tight for a real video-call home office. There is also no formal dining room broken out from the kitchen; that is intentional in an open-concept plan, but buyers who entertain formally should know it going in.
Finally, check the land before the plan. The single-story footprint plus a three-car garage demands a wider lot than typical infill parcels, so verify lot width before committing.
Who This Plan Is For
The most natural fit is empty-nesters or pre-retirees who want a true main-level home, with the basement or bonus room reserved for visiting family. Close to them are aging-in-place planners looking for vaulted-ceiling daily living without stairs, who can keep the basement option open for caregiver quarters down the line.
The plan also suits young couples planning to grow into the house, starting with one bedroom and finishing the basement when kids arrive. Beyond household stage, it fits homeowners on wide rural or suburban lots in the Southern coastal markets, where single-story farmhouses sit naturally on the land, and buyers who want a three-car garage without committing to a 3,000+ sf primary residence.
Regional Fit & 2026 Build-Cost Context
This single-story modern farmhouse footprint sits naturally across the Southern coastal belt this site covers: the wider lots, the indoor-outdoor porch culture, and the demand for main-level primary suites all line up. Below is how the plan reads market by market: the facade direction (from the eight further down the page) we would actually specify in each, the realistic 2026 turnkey build cost for this 1,715 sq ft heated footprint with the three-car garage, and the climate or code overlays a builder will need to engineer around.
In Charleston, SC we would build the Coastal Cottage Farmhouse (#2), with a turnkey allowance of $475,000–$830,000. The code baseline is IRC 2021 with ASCE 7-22 wind design at 130 mph, and flood-zone parcels add a raised first-floor elevation set by the local FIRM panels, which works against the step-free living that is this plan's main appeal. Savannah, GA points to the Classic Farmhouse with Copper Accents (#4) at $455,000–$795,000; the same IRC 2021 and ASCE 7-22 rules apply, and coastal A and V zone elevation requirements push foundation costs up on lots near the marshes.
Around Nashville, TN (Franklin / Brentwood) the darker Moody Modern Farmhouse (#1) suits the market, at $480,000–$840,000 turnkey. Climate zone 4A under IRC 2021 and the IECC calls for a heavier insulation envelope, and the vaulted great room should get a proper Manual J load calculation so the HVAC is not sized by rule of thumb. The Atlanta, GA (exurbs) range is $445,000–$780,000 with the Classic Farmhouse with Copper Accents (#4); climate zone 3A applies under IRC 2021 and the IECC, and this is the market where the basement option tends to cost less than finishing the bonus room over the garage.
Buyers around Charlotte, NC (Lake Norman / Waxhaw) get the Classic Farmhouse with Copper Accents (#4) as well, at $455,000–$790,000; the code picture is IRC 2021 with IECC climate zone 4A, and the wider suburban lots there take the three-car garage without setback variances. Naples / Ft. Myers, FL is the costliest and most demanding market for this plan at $545,000–$945,000, with the Coastal Cottage Farmhouse (#2) as the natural facade. The FBC 7th Edition and ASCE 7-22 place it in a 170+ mph wind zone, so impact-rated glazing is required throughout and the foundation is raised according to Florida elevation tables.
The Washington DC metro lands at $510,000–$890,000, with the Moody Modern Farmhouse (#1) as our facade pick. Climate zone 4A under IRC 2021 and the IECC governs the envelope, and for the aging-in-place buyers this one-level plan attracts, building to ICC A117.1 accessibility details from the start costs far less than retrofitting them later.
Methodology: Ranges cover the 1,715 sq ft heated envelope built to mid-builder-grade through low-architectural finish, plus the 3-car garage, basic site work, and standard permitting. Land, well/septic, custom landscaping, impact fees, slope-driven foundation upgrades, basement finish-out, bonus-room finish-out, and high-end specification packages (panel-front appliances, full slab counters, custom millwork) push above the upper bound. Ranges are synthesized from the NAHB 2024 Construction Cost Survey and the RSMeans 2026 City Cost Indexes, with pricing reviewed between Q4 2025 and Q1 2026. Always verify with two local builders before locking a budget; markets shifted noticeably between Q3 2025 and early 2026.
Other Facade Directions for This Plan
A note on the eight directions below: they are our own concept renderings of this floor plan under different exterior palettes, not options sold by the plan publisher, which ships the plan as the white board-and-batten elevation shown above. Building any of them means specifying the materials with your builder and an exterior designer.

1. Moody Modern Farmhouse
This is the contemporary direction for anyone who wants the modern farmhouse silhouette without the white-and-bright reading. Dark gray board-and-batten siding paired with a black shingle roof, warmed up with rich-toned wood garage doors, a wood front door, and timber porch columns. Landscaping carries the modern thread: manicured lawn, a concrete pathway lined with low bollard lights, and dark mulch around low-growing shrubs. This palette photographs especially well in late afternoon and reads sophisticated rather than stark.

2. Coastal Cottage Farmhouse
Charleston, Naples and other coastal lots are where this palette belongs. The siding is a soft robin's egg blue with crisp white trim, the whole roof is cool grey standing-seam metal, and the garage doors are whitewashed wood. A band of white gravel follows the driveway past lavender, ornamental grasses and river stones, so the yard reads like dune planting rather than lawn. It suits a beach-adjacent buyer who still wants the farmhouse silhouette.

3. Dramatic Black Farmhouse
Black siding and a black roof, warmed by wood garage doors, a wood front door and timber porch posts, make this the highest-contrast direction of the eight. The white window frames and white gable trim matter more than they first seem, because once the envelope goes fully dark they are what keep the windows and rooflines legible from the street. The landscaping is deliberately formal: dark geometric pavers set in grass, with clipped boxwood rows on beds of white gravel. A buyer with a modernist eye will see a statement facade here.

4. Classic Farmhouse with Copper Accents
The most traditional reading of the eight swaps the board-and-batten for cream horizontal lap siding and puts aged copper standing-seam roofing over the whole house, porch and window awnings included, with green patina already streaking through. Dark stained wood garage doors and timber porch posts keep it grounded. The driveway is edged in herringbone brick, and the beds on either side are full of lavender, roses and other flowering perennials. It is the right choice for someone who wants one premium material doing the talking rather than a bold color move.

5. Scandi-Industrial Farmhouse
Minimalist and Nordic-influenced: light gray vertical siding, a complete standing-seam metal roof in matching gray, and pale natural wood garage and front doors. The landscaping pulls it together: large concrete pavers set in dark river stone, with birch tree groupings and ornamental grasses for the Scandinavian texture. This is for the buyer who wants the farmhouse footprint stripped of its traditional ornament.

6. Rustic Craftsman Farmhouse
This blends farmhouse form with Craftsman material choices. Horizontal siding in a muted khaki with only a hint of olive covers the main body, natural cedar shakes fill the gables, and dark bronze metal roofing caps the porch under a slate-dark shingle main roof. The landscaping reads naturalistic and meadow-like: a grass-set permeable paver driveway, mixed wildflowers and grasses, and olive trees at both corners. We would suggest this for a countryside lot or for anyone drawn to natural materials and lower-maintenance plantings.

7. Mountain Craftsman Farmhouse
Anchored by a substantial stone veneer base, this version reads rugged and mountain-grounded: deep brown-gray board-and-batten siding, dark timber accents, and a black metal porch roof. The landscaping carries the woodland mood: exposed aggregate driveway edged with stone, plus ferns, hydrangeas, and ornamental grasses that thrive in dappled shade. This is our recommendation for mountain, lake, or wooded lots in Asheville, the Blue Ridge corridor, or the Smokies.

8. Midnight Modern Farmhouse
Shown at twilight, this one is black from the roof to the trim, and the only color comes from warm light glowing behind the multi-pane windows, the garage door lites and the front entry. Even the planting stays dark: heuchera and mondo grass flank a dark flagstone path picked out by low ground lights. Of the eight proposals it is the most editorial, best suited to someone who wants the whole facade to read as a single confident statement.
Frequently Asked Questions
Can this 1,715 sq ft plan really work as a long-term family home?
Yes, but only if you finish the basement option. As designed, the main level offers a single bedroom, which is sufficient for couples, retirees, or work-from-home professionals. To house a growing family, plan to finish the basement, which adds two bedrooms, two full baths, and a recreation room. Total finished space then approaches 3,200 sq ft, which is solidly family-sized.
How much does the basement finish add to the build cost?
In 2026 Southern markets, expect $60–$110 per finished square foot for a basement build-out that includes two bedrooms, a wet bar, two full baths, and a recreation room. For a roughly 1,500 sq ft basement footprint, that's $90,000–$165,000 on top of the heated main-level build cost. Markets with rocky or high-water-table sites push the higher end.
Will the three-car garage fit on a standard suburban lot?
The plan's footprint plus the three-car garage typically requires a lot at least 80 feet wide once you account for setbacks and driveway turning radius. That's wider than most infill suburban lots in established neighborhoods. New-construction subdivisions in the Charleston, Charlotte, and Nashville suburbs commonly offer lots in the 90–120 foot range that accommodate this plan comfortably.
Is this plan a good candidate for aging in place?
Strong fit. Everything you need for daily living is on the main level: primary suite, laundry, kitchen, great room. The 8'-6" by 14'-8" primary bath has the floor area to retrofit a curb-less shower and grab bars without a major remodel. The covered porches give safe outdoor access, and the basement option preserves space for caregiver or visiting-family quarters down the line. Ask your builder to specify 36-inch interior doors and a no-step front entry from day one.
Which facade direction holds resale value best in the Southern markets?
For mainstream resale, the Coastal Cottage Farmhouse and Classic Farmhouse with Copper Accents are the safest. They read as broadly attractive across most buyer profiles. The Moody Modern Farmhouse and Midnight Modern Farmhouse are stronger statements that perform well in markets with a younger design-forward buyer pool (Charleston, Nashville, Asheville) but may narrow your buyer audience in more traditional suburbs.

Who This Expandable Plan Suits
This is one of the better one-story modern farmhouse plans we have reviewed for the start-small-and-grow buyer. The 1,715 sq ft main level lives genuinely larger than its number, the structural framing for the bonus and basement options is the smart move that turns a one-bedroom plan into a four-bedroom home without renovation, and the exterior palette layers cleanly in any of the eight directions sketched above. If you're comparing single-story modern farmhouse plans in this size band, our review of the 1,988 sq ft flexible-bonus-space plan covers the next size up with similar bonus-room logic, and the 1,677 sq ft vaulted-great-room plan is the closest sibling on a tighter footprint. For a comparison against a similar single-story footprint in a different vernacular, our 2,030 sq ft Craftsman single-story review walks through the same daily-living priorities with a different exterior palette. Whichever direction you pick, this plan's headline feature is its growth path; if that flexibility matters to you, it's worth a serious look.
