See the Shocking 'Before' of This Spare Room Makeover!

Alex and Priya Whitman moved from Boston's Back Bay to West Ashley in spring 2023, bought a 1984 ranch, and asked me to help them turn the awkward 11'-6" × 10'-3" second bedroom into three things at once: a functioning remote-work office for Alex (software engineer, five Zoom calls a day), an occasional guest room for Priya's parents visiting from Boston, and a reading nook for Priya's evenings. Over eleven months I walked them through ten distinct design directions for the same footprint — from glamorous Art Deco to quiet Japandi — and priced each one against the specific constraints of a 118 sq ft Charleston spare bedroom: low ceilings (7'-10"), one small south-facing window, a single 24"-deep closet, no dedicated HVAC return, and a 20-amp shared circuit that couldn't support a new desktop workstation without a dedicated-circuit pull from the panel. This article is the full exploration: ten directions with real product specs, actual Charleston-small-room budget bands ($8,400 to $52,600), and the single direction the Whitmans picked when they finally had to commit.

What We'll Cover

Johan's Frame: The Whitmans' West Ashley Spare Bedroom

The Whitmans bought their West Ashley ranch in April 2023 for $518,000 — a modest 1,640 sq ft three-bedroom built in 1984 on a flat quarter-acre lot with mature live oaks. The second bedroom off the main hallway measured 11'-6" long by 10'-3" deep — 118 sq ft, 7'-10" ceiling height, a single 36"x48" south-facing window, a shallow 24"-deep reach-in closet with bifold doors, one supply vent and no cold-air return, and two 15-amp duplex outlets on a shared bedroom circuit. The existing state was a repurposed-storage wasteland — the previous owners had used it to warehouse decade-old boxes, a treadmill, and the rolling remains of a Christmas-tree stand. We gutted it to the drywall in the first week.

The brief was stubbornly multi-purpose: Alex needed a genuine home-office setup (two 27" monitors, a standing desk, Zoom-call lighting that wouldn't make him look jaundiced against an afternoon west-light backwash), Priya wanted a reading nook (soft chair, reading lamp, ottoman, bookshelf within reach), and both wanted the room to convert for Priya's parents two weeks per year into a guest room with a real bed. That triple-purpose demand is what pushed us through ten distinct directions — each style solves the functional problem differently, and the costs range from under $9,000 (Boho Plant Haven, which leans on soft goods and plants) to over $50,000 (Futuristic High-Tech Executive Suite, which needs integrated LED systems and an embedded 65" monitor in the wall).

The ten directions below are genuine alternatives we mocked up — not a buffet of visual references. Each has real product names, real Charleston-available vendors, and a budget band that reflects what this specific 118 sq ft footprint actually costs at a mid-range finish level in 2025. At the end I'll tell you which one the Whitmans built and why.

1. Glamorous Art Deco Retreat

Walls are wrapped in Graham & Brown Art Deco Geometric in Midnight Navy/Gold ($65/roll, 6 rolls for this footprint, $12/sf labor). The ceiling lifts slightly with a Hudson Valley Quincy 12-Light Sputnik in aged brass ($1,890). Furniture swaps: a Bernhardt Salon Mirrored Vanity with a Rove Concepts Hollywood Regency stool in performance velvet, and a Currey & Company Arlena Black-and-Brass console ($2,680). A blue velvet two-cushion sofa (Anthropologie Edlyn in Sapphire) in the reading corner anchors the space; a 5x7 Safavieh Courtyard Geometric rug in navy-and-gold grounds it. Wall molding upgrade — applied ogee picture-frame casing painted BM Hale Navy HC-154 — adds $1,400 in carpentry and reads authentic to the style. Charleston budget band: $22,400–$34,800.

Styling Notes for This Look

  • Ceiling height 7'-10" makes the sputnik read heavier than in a typical 9-foot room — consider the Hudson Valley 6-light variant ($1,240) instead.
  • Hale Navy HC-154 reads close to the wallpaper field and lets the gold geometry do the color work.
  • Mirror-faced furniture doubles perceived room size in a 118 sq ft footprint — worth the tradeoff on fingerprints.

2. Cozy Rustic Cabin Escape

The feature wall is reclaimed southern yellow pine from Mountain Lumber Company (Durham NC salvage, $18/sf delivered) — milled from 1890s barn timbers with the original saw kerf patterns preserved. The live-edge desk is an Odenheimer & Associates custom walnut slab from Hendersonville NC ($3,400 for a 54" slab on black steel hairpin legs). Seating: a Herman Miller Aeron Graphite for work (don't compromise on the work chair — Alex's shoulders are worth the $1,495) plus two Article Zanui Sheepskin Accent Chairs for the reading corner. A Vermont Castings Defiant Flex Burn electric fireplace insert adds ambience without a chimney. Rug is a Lorena Canals Bareback Cowhide (real hair-on, $680). Charleston budget band: $11,800–$16,400.

Styling Notes for This Look

  • Reclaimed wood feature walls in a high-humidity Charleston climate need an OSMO UV-Protection Oil finish ($4.40/sf) to prevent gray-out; untreated barn wood silvers inconsistently here.
  • Electric fireplace insert (no gas, no venting) stays code-compliant in a small bedroom per IRC R303.3.
  • Aeron chair against a rustic wood wall is a deliberate tension — ergonomics win over pure aesthetic in a daily-use office.

3. Sleek Monochrome Minimalist Office

Walls are BM Chantilly Lace OC-65 with a high-contrast BM Onyx 2133-10 on window, door, and baseboard trim (painter needs 72 hours of cut-line work — mask carefully). The desk is a Herman Miller Canvas Private Office in matte black laminate with a white worksurface ($3,840 for the single configuration). Desk chair is an Humanscale Freedom in white leather ($1,680). A BluDot Note Armchair in black leather anchors the reading corner, flanked by a floating MDF Italia Inmotion credenza. Flooring: the existing oak is stained Minwax Ebony and sealed with Bona Traffic HD. Rug is the classic Turkish Kilim in black/cream geometric (Minna, $780, 5x7). Lighting: Juno Trac-Master 12L track with four heads in black. Charleston budget band: $14,600–$21,200.

Styling Notes for This Look

  • Black trim reveals every drywall seam and corner imperfection — budget $900 for skim-coat level 5 finish before painting trim.
  • Existing oak stained ebony is 40% cheaper than replacing with new dark engineered flooring.
  • Track lighting over a work zone eliminates the single-overhead shadow problem in a small room.

4. Whimsical Boho Plant Haven

The lowest-cost direction and the most approachable for DIY. Walls are Clare Paint Terracotta Warm ($60/gallon, two gallons covers the small room) — a flat Saharan tone that behaves differently under Charleston's strong south light than under Boston's north light, so the Whitmans sampled it on three walls over 72 hours before committing. The macrame wall hanging is custom from local Charleston fiber artist Mell Bradshaw ($420 for the 36"x54" piece). A vintage 1960s peacock chair from Charleston Architectural Salvage on Meeting Street ($380, rattan restored with Bamboo Creations conditioning oil). Plants are all heat-tolerant Charleston picks: Monstera deliciosa, Hoya carnosa Krimson Queen, Ficus lyrata, and four Pothos Neon — sourced from Charleston Plant Co on Meeting Street. String lights are Brightech Ambience Pro 48' G40 (IP65, shatterproof). Rug mix: a Loloi Zharah Sand/Navy outdoor rug ($280) layered with a vintage Gogia Brothers Heriz ($640). Charleston budget band: $8,400–$12,600.

Styling Notes for This Look

  • Terracotta walls in a 118 sq ft room read dramatically warmer by evening — test with morning and evening photos before painting all four walls.
  • A real peacock chair takes more floor space than the photograph suggests — measure 36" diameter plus clearance.
  • Charleston Plant Co offers a houseplant health-check included in purchase — take them up on it in the first ninety days.

5. Futuristic High-Tech Executive Suite

The most expensive direction by a factor of three. Walls are clad in 2'x4' lacquered high-gloss MDF panels (Meganite Glossy White, $52/sf installed) with integrated WAC InvisiLED Pro 2700K strip routed into the reveal between panels — every 12" horizontal and vertical, creating an illuminated grid. The embedded display is a Samsung Frame 65" in matte white bezel, flush-mounted with a Sanus VXF-727 low-profile frame ($3,600 + $480 install). Desk is a Nomique Elevate Standing Desk in white glass-top ($2,240). Chairs are two Knoll Saarinen Executive in black leather on chrome pedestal ($1,680 each). Flooring is a polished concrete overlay (Ardex PC-T, $14/sf installed over the existing subfloor after hardwood removal) with a Gan Sail Rug in Dove Gray 6x8 ($1,480). Lighting program runs on Lutron RadioRA 3. The four-circuit electrical pull and dimmer integration alone adds $4,800 in panel work. Charleston budget band: $28,400–$52,600.

Styling Notes for This Look

  • LED-integrated wall panels in a 118 sq ft room produce measurable heat — plan the Mitsubishi MSZ-FH06NA mini-split at 6,000 BTU as an ancillary cooling head.
  • Samsung Frame TV in matte mode reads as art during Zoom calls — acceptable background even on a large 65" scale.
  • Polished concrete overlay over a wood subfloor requires dimensionally-stable underlayment; skip this if the subfloor has ever flexed.

6. Stylish Mid-Century Modern Study

Walls are BM Indian White OC-87 — a warm off-white that flatters walnut and rattan without going cream. The desk is a West Elm Mid-Century Desk in acorn walnut veneer ($1,780) — not a solid piece, but honest for the price. If budget allows, upgrade to Room & Board Milo in solid walnut ($2,840). The desk chair is an authentic Herman Miller x Eames Aluminum Group Management Chair in polished aluminum and cognac leather ($3,980) — a real investment, the difference between reproduction and authentic reads on resale as much as on look. The long credenza is Article Envelop Walnut Cane ($1,640). Two Article Sven Chairs in Grass Green velvet flank a Muuto Around Coffee Table in solid oak ($640). Jute rug is Safavieh Natural Fiber 5x7 ($380). Brass arc lamp is a Koncept ZBar Solo Mini in brushed brass on an oak base. Charleston budget band: $16,400–$24,800.

Styling Notes for This Look

  • Eames Management Chair authenticity is verifiable at Herman Miller's online checker (reproduction Aluminum Group chairs typically hit $1,000–$1,400 — they look close and resell for 10–15% of retail).
  • Grass Green velvet reads saturated in Charleston's strong south light — sample test in the actual room before committing to a full sofa.
  • Walnut veneer furniture is fine in a climate-controlled room; solid walnut would cost roughly 55% more.

7. Serene Scandinavian Minimalist Nook (The Whitmans' Chosen Direction)

This is what we built. The direction delivered on all three functional requirements in the smallest total footprint with the cleanest visual line. Walls are Farrow & Ball Cornforth White 228 — a cool pale gray that handles the south-facing light without glare. The wall of floor-to-ceiling built-in wardrobes runs the 11'-6" length: custom from Charleston Custom Closets in rift-sawn white oak veneer over Baltic birch carcass, flush-front push-to-open, with one bay dedicated to a Murphy bed conversion (a Resource Furniture Hover twin wall-bed, $4,980, opens to a Serta 10" memory-foam twin — Priya's parents sleep on it two weeks per year). The built-in takes $6,800 of the total budget and absorbs every piece of clutter this room ever held. The floating desk is a 48" custom live-edge piece by Knight Woodworks in Charleston, white-oak over a cantilevered steel bracket, $1,480. Desk chair is a Humanscale Diffrient Smart in light gray mesh. The reading corner holds a Made.com Niamh Boucle Accent Chair in Ivory ($680) and a Muuto Around Coffee Table Oak Small ($480). Large round mirror: Umbra Hub 37" in matte brass. Rug: Armadillo Sierra Weave in Natural ($1,240, 5x7). Pendant over the desk: Louis Poulsen PH 2/1 Table Lamp ($520) and a Menu Carrie LED Lantern for the reading corner. Built cost: $14,800 all-in.

Styling Notes for This Look

  • Farrow & Ball Cornforth White is spec'd and not substituted — Benjamin Moore's closest match (Stonington Gray HC-170) reads noticeably warmer and cracks the visual discipline.
  • Charleston Custom Closets' flush-front push-to-open hardware stays clean-line visually even when cat-paw scuffs happen — worth the extra $400 over handle-pull hardware.
  • Murphy bed with memory-foam mattress (not conventional spring) fits into Resource Furniture's 10" depth spec — check before ordering mattress.

8. Moody Dark Academia Library

Walls are Farrow & Ball Off-Black 57 with a Hague Blue 30 accent on the window-wall trim. Floor is engineered hardwood in Mirage Herringbone Walnut (replacing the existing oak, $16/sf installed including rip-up). Bookshelves are custom floor-to-ceiling from Knight Woodworks in Charleston — solid walnut with adjustable shelves, filling the full 10'-3" back wall ($7,400 for the built-in). Desk is a Bernhardt Jet Set Executive in dark walnut veneer ($1,840). Desk chair is a Restoration Hardware Churchill Leather Tufted in Italian brown saddle leather ($2,680 — the tufted leather is the single piece that carries the direction visually). An ornate framed vintage map (Antique Charleston 1860 Harbor Chart reproduction from Charleston Maps & Prints, $640) anchors the wall opposite the bookshelf. Industrial floor lamp: Rejuvenation Bergen Tripod in dark brass ($780). Rug: Orley Shabahang Persian Heriz runner ($1,980). Charleston budget band: $19,200–$28,600.

Styling Notes for This Look

  • Off-Black 57 looks almost-black in north light and revealingly gray in south light — Charleston's south-facing window here shows the undertones, which the Whitmans felt fought the direction.
  • Custom floor-to-ceiling bookshelves in a rental market are cost-efficient built-ins; Charleston Knight Woodworks' lead time was 14 weeks when I checked.
  • Leather tufted chairs develop patina in 70–85% humidity faster than in dry climates — condition with Leather Honey every 4 months.

9. Bright and Airy Coastal Retreat

Walls are nickel-gap 5" shiplap (pre-primed MDF, $4.20/sf material + $3.80/sf install) painted BM Simply White OC-117. The desk is a Serena & Lily Gisele Desk in matte white ($1,180). The console is a Pottery Barn Reynolds 4-Drawer Console in White ($1,460). Window treatment: woven wood Roman shades in Hunter Douglas Provenance Driftwood ($520/window). An Article Sven Twin Armchair in Ivory Boucle sits in the reading corner with a Lulu & Georgia Beatrice driftwood side table. A jute 5x7 rug from Annie Selke (Dash & Albert Majorca Sisal, $380) grounds the floor. Accessories: sea glass in a shallow ironstone bowl, a Charleston pelican watercolor from local artist Harriet Sobol ($280). Charleston budget band: $9,800–$14,200.

Styling Notes for This Look

  • Nickel-gap shiplap in high-humidity Charleston air holds better than traditional tongue-and-groove — the MDF version is stable to 85% RH if primed all six sides before install.
  • Serena & Lily's coastal aesthetic reads authentic in Charleston where it feels performative in, say, Austin — lean into the regional match.
  • Woven wood Roman shades require lining for full blackout; skip the lining and plan for a deep-sleep guest mode workaround.

10. Minimalist Japandi Sanctuary

Walls are Portola Paints Lime Wash in Hacienda — a tonal beige-warm that hand-trowels in vertical strokes ($3,600 for the small-room application by an experienced trowel-finish applicator, Coastal Lime Finishing). The floor is half-and-half: a fiber-sisal base with two authentic igusa tatami mats (6'x3' each, Ikko Kyoto, $1,400 for the pair) defining the reading/meditation corner. Desk is a Pinch Nim Desk in Smoked Oak ($2,940 from Pinch London, direct ship). Desk chair is a Muuto Cover Side Chair Oak ($480). A floor cushion (Armadillo Piet in Carob, $280) replaces the reading chair for the Japanese side of the blend. Low shelving is a Skagerak Pine Shelving System (natural oak, $580). Paper pendant: authentic Yamagiwa Akari 75A Noguchi ($340). A Juniperus procumbens Nana shohin bonsai on a Tokonoma stand from Dallas Bonsai ($220). Linen roman shades (unlined, The Shade Store, $640). Charleston budget band: $17,800–$26,400.

Styling Notes for This Look

  • Portola Lime Wash requires a trowel-finish applicator — not all Charleston painters take these jobs; Coastal Lime Finishing and GlobalArt Finishes both do.
  • Authentic tatami from Ikko Kyoto ships in 8–10 weeks; Home Depot "tatami-style" fiberboard versions read fake in this much exposure.
  • Shohin bonsai need morning sun — place within 3 feet of the south-facing window and rotate weekly.

Pro Tips: Small-Room Realities in Charleston

  • Room audit before direction selection. Measure length, width, ceiling height (Charleston 1980s ranches often hit 7'-10", not 8'-0" or 9'-0"), window locations, door swing, HVAC supply/return, outlet locations and circuit assignments, and any structural quirk (soffit, knee wall, dormer). A 118 sq ft room with 7'-10" ceilings reads visually smaller by roughly 12% than the same footprint at 9'. Every direction below was sized against this specific audit.
  • Charleston humidity is the quiet antagonist. Interior RH runs 55–70% even with central air in summer; untreated hardwoods, unsealed plaster, and natural-fiber rugs without moisture barriers all pay the price. Specify zero-VOC low-permeability paints (BM Aura, Farrow & Ball Modern Emulsion, Clare Paint), GREENGUARD Gold textiles, and any natural-fiber rug on a Rug Pad Corner Cushioned Luxe pad. Run a Frigidaire 50-pint dehumidifier on the shared HVAC return if the room has moisture issues.
  • Dedicated circuit for the home office is non-negotiable. A two-monitor setup plus computer plus ring light plus charger bank plus task lamp pulls near 15 amps at peak; run a dedicated 20A circuit from the panel, use TR receptacles per NEC 406.12, and add an AFCI breaker per NEC 210.12(B). Budget $1,200–$1,800 for the pull on a 30-foot run.
  • Lighting to IESNA home-office targets. Minimum 30 lumens/sf ambient + 50 lumens/sf task. For the Whitmans' 118 sq ft that's 3,540 lumens ambient (one 15W LED recessed 4" downlight + a pendant) plus 5,900 lumens task at the desk surface (task lamp on dimmer + under-cabinet LED). Color temperature: 2700K for ambient, 3500K–4000K for task — Lutron Caseta dimmers handle both on one wall plate.
  • Acoustic isolation for remote work. Five-minute Zoom calls won't matter; six-hour product reviews will. Add Roxul Safe'n'Sound ($2.80/sf) in the wall cavity during any drywall carve, and a QuietRock 530 5/8" over the existing drywall where you can ($48/sheet). That combination hits STC 52+ — blocks HVAC whoosh, muffles guest-room TV, and cuts neighbor-dog background noise measurably.
  • Built-in storage returns the room to sanity. Charleston Custom Closets, California Closets, Inspired Closets, and Closet Factory all quote 10x12 single-bay builds in the $2,800–$6,400 range. The Whitmans spent $6,800 for floor-to-ceiling built-ins with integrated Murphy bed — the highest-ROI single line item in the project.
  • HVAC supply and return are often wrong in 1980s additions. 118 sq ft needs one 4"x10" supply and a dedicated return (or a door undercut of 3/4" minimum). If your room overheats or under-heats relative to the rest of the house, a Mitsubishi MSZ-FH06NA 6,000 BTU mini-split head ($2,400–$2,800 installed) solves it at lower cost than re-engineering the trunk. The Whitmans' existing ductwork was adequate — we added a return grille and skipped the mini-split.
  • Window treatment for triple-duty rooms. Layered: solar shade 1% openness behind a drapery panel gives you Zoom-call privacy without fully darkening the room, and the drapery panel pulls shut for guest-room blackout mode. Hunter Douglas Duette Architella or the Shade Store Classic Roller Shade in 1% openness sit at $420–$680/window.

Regional Cost Comparison Across 7 Markets

Frequently Asked Questions

Can we genuinely combine a home office, guest room, and reading nook in 118 sq ft?

Yes, but only if one of the three functions uses vertical space and a conversion mechanism. In the Whitmans' case, the Murphy bed inside the built-in wardrobe wall handles guest-room mode without displacing office equipment; the reading nook uses a 28" boucle chair that occupies 4.5 sq ft of floor and tucks under a desk corner when not in use. A sofa-bed solution occupies permanent floor area (roughly 24 sq ft open) and doesn't work in this footprint — Murphy beds, wall beds, and folding-desk solutions are the right move in any room under 140 sq ft asked to triple-purpose.

What about natural light for remote video calls?

Position the desk so the window is at a 90-degree angle to your face, not behind or in front of you. A south-facing Charleston window (Alex's specific situation) creates backlit-backwash on Zoom from about 9am to 1pm year-round — unusable on a work call without a 1% solar shade to knock down the field and a 3500K LED task light at roughly 900 lumens aimed from 30 degrees off-axis to fill your face. We used the Hay Matin table lamp ($490) on a dimmer. On cloudy Charleston days, the same setup reads natural without flattening; on bright days the solar shade stays 40–60% down during peak sun.

Do we need a permit for built-in wardrobe or floor-to-ceiling bookshelves?

No for non-structural built-ins attached to studs via French cleats or Z-clips — Charleston treats these as furniture. Yes if you're modifying load-bearing walls, adding a new electrical circuit (dedicated desk circuit), relocating HVAC ductwork, or altering plumbing. The electrical dedicated-circuit pull on the Whitmans' project took $180 in permit fees plus a one-day rough and final inspection; the built-in wardrobe did not. Confirm with Charleston Building Services before any demo — their office on Lockwood Drive turns around preliminary questions in 24–48 hours.

What's a realistic single-room budget for a full makeover?

Charleston baseline for a 100–150 sq ft spare bedroom conversion with professional design, quality built-ins, paint, lighting layering, furniture, and soft goods: $14,000–$22,000 at mid-range, $8,000–$12,000 at budget (paint + good thrift + one anchor furniture purchase), $35,000–$60,000 at high end (custom millwork full-perimeter, designer fabrics, authentic vintage pieces, premium lighting). Beware anyone quoting under $6,000 — that's furniture-store scope, not a real makeover.

How do we handle acoustic isolation without gutting the walls?

Three-layer approach without gutting: (1) add a QuietRock 530 5/8" sheet over the existing drywall on the shared walls ($48/sheet + labor $1,400 for the room), (2) seal every outlet and switch box with Roxul Safe'n'Sound putty pads ($14 each), (3) add a heavy drapery panel over the door or the door itself on the inside face. Combined, this gets you from STC 32 (standard 1980s drywall-over-insulated-stud) to STC 44–48 — enough to cut HVAC whoosh and most conversational sound. For full remote-podcast quality, gutting and adding Safe'n'Sound in the cavity pushes to STC 52+.

Can we add a Murphy bed under a $16,000 budget?

Yes. The Resource Furniture Hover Twin Wall Bed ($4,980) or the Italian-made Clei Penelope 2 Twin ($3,890) both fit within the budget if the rest of the room uses existing or refurbished pieces. The less-premium IKEA PAX + Closet Works Murphy conversion ($1,900–$2,400 total) reads amateur visually and lacks the push-open mechanism smoothness but works mechanically. The Whitmans used the Resource Furniture Hover, which runs quieter and handles memory-foam mattresses up to 10" depth.

Does a personalized direction like Dark Academia or Art Deco hurt resale?

For a spare bedroom specifically, no — because it's easily converted back or repainted in 1–2 days by the next owner. Charleston MLS data on 29407, 29414, and 29420 (West Ashley and James Island zips) from 2023–2025 shows that a renovated, permitted, functional spare bedroom returns 78–92% of invested cost at resale regardless of style direction, as long as the built-in storage is flexible (removable shelving, neutral carcass, adjustable hanging rods). Dark paint and custom bookshelves cost the same $200–$400 repaint job as any other direction. Resale-hostile choices are wallpaper with pattern alignment issues, painted-over hardwood, and unpermitted electrical.

Final Thoughts

The Whitmans' Scandinavian Minimalist Nook has been fully operational since August 2024. Alex takes his Zoom calls from it daily, Priya reads there four evenings a week in the boucle chair, and when her parents visit (they've come twice since the room was finished), the Murphy bed drops cleanly from the built-in and the daybed-desk transition takes three minutes. Total built cost was $14,800 all-in — within $200 of my initial direction estimate and roughly half what the Art Deco or Futuristic High-Tech directions would have cost. The reason it won over the more photogenic options was specifically its discipline: it did every job without visual noise, and in a 118 sq ft room, visual noise is the only thing that can't be undone with a coat of paint.

If you're starting the same exploration on your own spare bedroom — in Charleston or anywhere — the sequence I use is: room audit first, direction shortlist to three, mock-up of built-in storage in the shortlist, and budget against the actual quotes from real vendors before committing. Pinterest inspiration boards and Instagram reels cost nothing; custom built-ins cost a quarter of your total budget. Get the numbers real before you fall in love.

For more spare-room and single-space transformations, I've written companion studies at From Cluttered Chaos to Serene Sanctuaries: 11 Incredible Spare Room Makeovers, The Ultimate Room Reveal: 11 Stunning Transformations from a Cluttered Mess, The Ultimate Living Room Revival: 12 Stunning Transformations from Chaos to Calm Retreat, and for lower-level work From Cluttered Basement to Stylish Sanctuary: 11 Stunning Transformations.
