Last updated: April 2026

I've spent the last three years translating Korean interior design content for English-speaking renters and homeowners trying to copy the look. Two neighborhoods come up over and over: Hannam-dong and Seongsu-dong. They're the two poles Korean interior design has been orbiting since 2022, and in 2026 the gap between them has actually widened — not narrowed. According to a January 2026 report from 오늘의집 (Ohouse), Korea's largest interior platform with 30 million users, "Hannam-style" project saves grew 41% year-over-year while "Seongsu-style" saves grew 67% — the two fastest-growing aesthetic tags on the platform (Ohouse Trend Report, 2026). This guide breaks down both, with prices, sources, and the exact products Korean designers are specifying right now.

What Is the Hannam-dong Aesthetic, Really?

Hannam-dong sits on the north bank of the Han River, wedged between Itaewon and the Namsan slope. It's been Seoul's diplomatic quarter since the 1960s — embassies, ambassadors' residences, the UN Village compound. Sotheby's International Realty describes it as "the cosmopolitan capital of calm luxury," and that phrase — calm luxury — is the core of the aesthetic. Korean designers call it 조용한 럭셔리 (joyonghan luxury), literally "quiet luxury."

The visual language is restrained, expensive, and obsessively material-driven. You won't see bold color. You won't see industrial elements. What you will see: white oak floors laid in long planks, lime-plaster walls (석회 미장) with a hand-troweled texture, travertine or honed marble in bathrooms, brushed brass hardware, and one or two museum-grade art pieces hung at gallery height (typically 145cm to center, translated from Korean spec sheets I review weekly).

The Hannam Material Palette

The materials list is short and expensive. Here's what I see specified across roughly 80% of Hannam-dong renovation portfolios on 오늘의집 in 2026:

• Floors: White oak (화이트 오크) or natural oak engineered planks, 220mm wide minimum, oil finish (not lacquer). Average 2026 cost: ₩180,000–₩280,000 per pyeong installed (~$133–$207/3.3m²)
• Walls: Lime plaster (석회 미장) in off-white, ivory, or warm gray. Cost: ₩120,000–₩180,000 per pyeong (~$89–$133/3.3m²)
• Counters: Honed travertine, Calacatta Viola marble, or Taj Mahal quartzite. Cost: ₩900,000–₩2,400,000 per slab (~$665–$1,773)
• Hardware: Brushed brass or aged bronze pulls, typically from Buster + Punch (UK) or domestic brand 더한섬 (Thehansum). Cost per pull: ₩45,000–₩120,000 (~$33–$89)
• Lighting: Plaster sconces (Allied Maker, RBW), linen drum pendants, recessed pinpoint lighting

Hannam Color Theory

The Hannam palette is what Korean stylists call 무채색 + 따뜻한 베이지 (achromatic plus warm beige). Roughly: warm white walls (Benjamin Moore "Swiss Coffee" or domestic equivalent 노루페인트 "오트밀"), oak tones for floors and built-ins, a single dark accent (charcoal sofa, black metal door frame, espresso leather chair), and one piece of natural-tone art. According to design firm 스튜디오 fnt's 2026 portfolio review, 73% of their Hannam clients specify three colors or fewer in any given room.

Who Lives in Hannam-dong (And Why It Matters for the Aesthetic)

Hannam-dong is genuinely expensive — apartments at Hannam The Hill regularly trade for ₩7–14 billion (~$5.2M–$10.3M) according to Korea's Real Estate Board (2026 Q1 data). The residents skew older, wealthier, and more art-collecting than the rest of Seoul. That demographic produces a specific design brief: rooms that won't go out of style, finishes that improve with age, and storage that disappears into millwork. There are no open shelves of plants and ceramics here. Everything has a closed door.

The neighborhood's gallery density also shapes interiors. Hannam holds the Leeum Samsung Museum of Art, plus more than 30 private galleries within a 10-minute walk of the Hannam Bridge. That proximity means residents — many of whom are collectors — design their living rooms around art they own. You'll see purpose-built picture rails, museum-grade lighting (typically Erco or RBW track at 3000K, 92+ CRI), and walls finished in flat plaster specifically to avoid glare on framed work. Translated from a 2026 Plain Studio client interview: "절반의 고객은 거실 설계 전에 어떤 그림을 걸 건지 먼저 알려줘요." ("Half of our clients tell us which painting will hang in the living room before we even design it.")

The Hannam Furniture Pull List

If you want to copy the look, the furniture brands actually used are tighter than people expect. From the same 80% portfolio sample: Vitra (DSW chairs, Nelson lamps), Carl Hansen (CH24 Wishbone), de Sede (DS-600 sofa), USM Haller storage, Artek 60 stools, plus domestic-Korean pieces from 챕터원 (Chapter One), 핀란드디자인숍 (Finnish Design Shop Korea), and more recently 더한섬홈 (The Hansum Home). Mid-century European with Japanese and Korean accents — that's the formula. Average sofa investment runs ₩6.8M–₩14M (~$5,022–$10,340), translated from 2026 Chapter One pricing.

What Is the Seongsu-dong Aesthetic, Really?

Seongsu-dong is two miles east of Hannam, across the Han, in Seongdong-gu. Until the early 2010s it was a working industrial district — leather tanneries, shoe factories, printing presses, auto-repair garages. Then artists moved in for the cheap rent. Then cafés. Then Dior built a flagship in a renovated warehouse. Tatler Asia called Seongsu "Seoul's coolest neighbourhood" and the comparison everyone uses is "the Brooklyn of Seoul" — specifically, Williamsburg circa 2014.

The aesthetic is the inverse of Hannam in almost every way. Where Hannam hides structure, Seongsu exposes it. Where Hannam uses honed stone, Seongsu uses raw concrete. Where Hannam's color story is monastic, Seongsu's is grayscale-plus-rust. The neighborhood's dominant interior style in 2026 is what Korean designers tag as 인더스트리얼 빈티지 (industrial vintage) or 로우 스타일 (raw style).

The Seongsu Material Palette

I've translated the spec sheets for six published Seongsu-dong residential projects from late 2025. The pattern is remarkably consistent:

• Floors: Polished concrete (₩90,000–₩140,000 per pyeong, ~$66–$103/3.3m²), reclaimed pine, or epoxy-sealed screed
• Walls: Exposed brick (real or veneer), raw concrete (노출 콘크리트, nochul concrete), or microcement
• Ceilings: Exposed black-painted ducts, raw rebar, or stripped-back joists
• Partitions: Black steel-frame glass walls (철제 파티션) — the single most-saved Seongsu element on Ohouse in 2026, according to their February trend report. Cost: ₩450,000–₩900,000 per linear meter (~$333–$665)
• Lighting: Vintage factory pendants, bare Edison bulbs on black cloth cord, exposed conduit track lighting
• Furniture: Reclaimed-wood dining tables, leather Chesterfield sofas (often from local maker 모벨랩 Mobellab), Tolix chairs or knockoffs

Seongsu Color Theory

Seongsu's palette is darker, dirtier, and more saturated than Hannam's. The base is concrete gray and warm wood, the accents are oxidized black metal and cognac leather, and there's almost always one bold material moment — a bright cobalt door, a rust-red painted column, a poster-sized vintage print. Designer 이수진 (Lee Su-jin) of 0_1 Studio told 마이홈 magazine in March 2026: "성수 스타일은 모순의 미학이다. 차가운 콘크리트와 따뜻한 가죽, 거친 벽돌과 부드러운 리넨이 같은 방에 있어야 한다." (Translated: "The Seongsu style is the aesthetics of contradiction. Cold concrete and warm leather, rough brick and soft linen, all need to live in the same room.")

Who Lives in Seongsu-dong (And Why It Matters)

Seongsu's resident profile is younger — designers, founders of small fashion labels, photographers, café owners. According to KB Real Estate's 2026 neighborhood report, the median age of a Seongsu apartment buyer is 34, versus 51 in Hannam-dong. That demographic produces a different brief: rooms that photograph well, finishes that look intentional rather than precious, and a willingness to live with imperfection (a chip in the concrete is character, not a defect).

The neighborhood's commercial density also feeds the residential look. Seongsu has the highest concentration of independent cafés in Seoul — 312 active locations as of March 2026 per Seongdong-gu's small business census — and many of those cafés are designed by the same studios doing residential work in the area. Studios like 0_1, Plain, Studio Lim, and 라보토리 (Labotory) routinely cross-pollinate café and home aesthetics. Result: Seongsu apartments often feel like the residential extension of a café concept, with built-in espresso bars, café-style banquette seating, and oversized communal tables replacing traditional dining sets.

The Seongsu Furniture Pull List

The furniture roster looks completely different from Hannam. From a translated review of six 2026 Seongsu project portfolios: vintage Tolix Marais A chairs (originals or knockoffs from 모벨랩, ₩180,000–₩620,000 each, ~$133–$458), reclaimed-wood plank dining tables from 우드앤브릭 (Wood and Brick), worn leather Chesterfield sofas from 모벨랩 or 더로우 (The Row, ₩3.4M–₩6.8M, ~$2,510–$5,022), Eames LCW chairs (originals or Korean replicas), and increasingly, custom-welded steel pieces from local fabricators. Soft furnishings tend to be linen and rough cotton rather than the wool-cashmere blends preferred in Hannam. The look should read "intentionally chosen" rather than "consistently expensive."

How Do Hannam and Seongsu Compare on Renovation Cost in 2026?

This is the question I get asked most. The short answer: Hannam costs roughly 60–80% more per pyeong than Seongsu for a comparable renovation. The longer answer involves a real cost breakdown, which I've translated and converted from a March 2026 quote comparison published on the Korean designer forum 인테리어 광장 (Interior Plaza).

Per-Pyeong Cost Breakdown (3.3 m² / 35.5 ft²)

Line item	Hannam spec	Seongsu spec
Flooring	₩220,000 (~$163) — white oak engineered	₩110,000 (~$81) — polished concrete
Wall finish	₩150,000 (~$111) — lime plaster, hand-troweled	₩70,000 (~$52) — raw concrete sealer
Ceiling	₩90,000 (~$67) — flat plaster, recessed lighting	₩40,000 (~$30) — exposed structure, black paint
Kitchen counters	₩2,100,000/slab (~$1,551) — Calacatta Viola	₩650,000/slab (~$480) — black soapstone
Bathroom	₩4,800,000 (~$3,545) — travertine, brushed brass	₩2,400,000 (~$1,772) — microcement, black matte
Lighting (per fixture)	₩380,000 (~$281) — Allied Maker plaster	₩140,000 (~$103) — vintage factory pendant
Total per-pyeong avg	₩480,000 (~$354)	₩290,000 (~$214)

Why the Gap Is So Wide

Three things drive the Hannam premium. First, materials: lime plaster and engineered oak cost roughly 2x what concrete and screed cost. Second, labor: hand-troweled plaster needs a specialist, and Korea has maybe 200 people who do it well — they charge accordingly. Third, finish tolerance: Hannam clients reject work for hairline imperfections that Seongsu clients celebrate as character. That's not a joke; it's in the contracts.

Where the Costs Converge

Plumbing, electrical, demolition, waste disposal, and HVAC don't care about your aesthetic. Those run roughly the same in both styles — about ₩180,000–₩240,000 per pyeong ($133–$177/3.3m²) in 2026 for a full apartment, according to data from 집닥 (Zipdoc), Korea's largest renovation marketplace. So a 30-pyeong (1,065 ft²) apartment lands at roughly ₩19.8M ($14,629) all-in for a Seongsu spec versus ₩31.2M (~$23,054) for Hannam. Add another 12–18% for project management, permits, and contingency. Most Korean designers quote turnkey numbers that include this overhead; American expat clients often miss it on first quotes and get surprised by the final invoice.

Which Aesthetic Works Better for Renters and Small Apartments?

If you're renting in Korea (전세 or 월세) or working with a small apartment under 20 pyeong (~710 ft²), Seongsu wins on most metrics. Hannam's signature moves — built-in millwork, full-wall plaster, stone bathrooms — are landlord-killers. You can't unrip them at move-out without losing your deposit. Seongsu's moves are mostly additive and removable.

What You Can Actually Do as a Renter

Korean rental contracts (전세 or 월세) almost always include a 원상복구 (wonsangbokgu, "return to original state") clause. Drilling, painting, and permanent fixtures usually require landlord permission and will be charged against your deposit. Within those constraints:

• Seongsu rental moves that work: Freestanding industrial bookshelves (try Korean brand 일루일루 Iluilu), rolling steel garment racks, vintage rugs over existing flooring, plug-in sconces clamped to shelves, freestanding partition screens
• Hannam rental moves that work: Linen curtains floor-to-ceiling, oak-veneer self-adhesive panels for accent walls (peelable), warm-tone area rugs, brass-pull cabinet retrofits (originals stored for move-out)
• Don't try at home: Lime plaster (permanent), exposed concrete (you can't fake it convincingly without demo), real exposed brick

For a deeper renter playbook, see our Korean Rental Interior: How to Decorate Without Losing Your Deposit guide.

The Small-Apartment Calculation

In apartments under 20 pyeong, Hannam's restraint can read as sterile and Seongsu's clutter can read as chaotic. Designer 박정현 (Park Jung-hyun) of Plain Studio recommends what she calls "70/30 leaning" — pick a primary aesthetic for 70% of visible surface, then borrow 30% from the other. In a small 17-pyeong (~600 ft²) apartment, that might mean Hannam-style oak floors and white plaster walls, with one Seongsu-style black steel-frame glass partition between living and bedroom areas. That single partition does heavy lifting: it adds visual depth, defines zones without losing light, and gives the room a 2026 photographic quality without committing to a full industrial gut renovation.

Storage Strategy by Style

Hannam apartments hide everything behind flush millwork — push-to-open cabinets, integrated appliances, no visible hardware. Budget 18–25% of total renovation cost for built-ins. Seongsu apartments display everything — open metal shelving, exposed garment racks, vintage trunks as side tables. Storage budget drops to 6–10% but you spend more on the objects you're displaying. Both approaches work; they fail when mixed without intent.

Lighting Strategy by Style

Lighting is where most renter and small-apartment translations get tripped up. Hannam-style lighting is layered and warm: typically four to six layers per room (recessed pinpoint at 2700K, plaster sconces flanking key walls, a single drum or linen pendant over seating, two table lamps, picture lights for art). Seongsu-style lighting is fewer fixtures but bigger: one or two oversized industrial pendants, exposed-bulb track for general light, and that's often it. The Hannam approach costs roughly ₩2.8M–₩5.4M ($2,067–$3,988) per room in fixtures alone. Seongsu typically lands at ₩900,000–₩1.8M ($665–$1,329) per room. If you can only afford to copy one detail from either neighborhood, lighting choice has the highest visual impact per dollar.

What Are the Best 2026 Hybrid Approaches?

Most Koreans actually building right now aren't picking one pole. They're hybridizing. The cleanest hybrid I've seen specified repeatedly in 2026 portfolios is what Plain Studio calls the "Hannam shell, Seongsu soul" approach. Hannam-grade bones — oak floors, plaster walls, stone counters — with curated Seongsu accents — one black steel partition, one raw concrete feature wall, vintage industrial pendant lighting in the dining zone.

The 80/20 Hannam-Seongsu Hybrid

Roughly 80% Hannam materials, 20% Seongsu accents. This is what shows up in luxury new-build apartments in Yongsan and Seongdong — buildings like Acro Seoul Forest and The Sharp Galleria are pricing 2026 units with this exact spec. Per-pyeong renovation cost lands around ₩410,000 (~$303/3.3m²), splitting the difference between pure Hannam and pure Seongsu.

The 50/50 Split

Trickier to execute but increasingly popular among the 30-something demographic with money. Half the apartment reads Hannam — typically the bedroom, bathroom, and primary living area. The other half goes full Seongsu — typically a home office or studio space, kitchen, or "café corner." The visual transition usually happens at a black steel-frame doorway, which acts as both the literal and aesthetic boundary.

What to Avoid

The hybrid that consistently fails: Seongsu shell with Hannam accents. Raw concrete walls plus brushed brass plaster sconces plus travertine bathroom reads confused, not curated. The reason, per designer 이수진: the Hannam materials look apologetic against industrial backdrops, like they wandered into the wrong room. The reverse — luxury bones with industrial moments — works because the industrial elements feel intentional rather than incomplete.

Where Do Korean Designers Source the Right Materials?

The sourcing geography matters because it's actually different for each style. According to the JJJOZ Blog's January 2026 designer sourcing guide, three Seoul districts dominate professional material sourcing — and each leans toward one aesthetic.

Seongsu-dong's Own Material District

For Seongsu materials, you source in Seongsu itself. The neighborhood's history as Seoul's leather working district means tanneries, shoe-factory remnants, and material suppliers cluster within walking distance. Boutique shops like 성수공방 (Seongsu Workshop) and 메탈 그라인드 (Metal Grind) carry the black steel, reclaimed wood, and concrete-stain products that define the look. Per the JJJOZ guide, Seongsu suppliers are "slower to navigate but more informative about what is currently considered interesting in Seoul's design community."

Eulji-ro for Crossover Hardware

Eulji-ro (을지로), an older industrial district near the Cheonggyecheon stream, supplies both styles. It's where Korean designers source vintage factory pendants for Seongsu projects and brushed brass hardware for Hannam projects from the same metalsmiths. Hardware costs run ₩30,000–₩180,000 per piece (~$22–$133) depending on finish and complexity.

Imported Stone and Plaster from Itaewon and Gangnam

For Hannam-grade materials, designers source higher up the price ladder. Travertine and Calacatta marble come through importers in Gangnam and Banpo. Lime plaster materials — especially Italian Marmorino and Tadelakt — come through specialty distributors in Itaewon. A typical Hannam material order in 2026 is 60% imported, 40% domestic. A typical Seongsu order inverts: 75% domestic-sourced, mostly recycled or reclaimed.

Online Sources Worth Translating From

The two best Korean-language sources for material research in 2026 are 오늘의집 (Ohouse) and 마이홈 (My Home). Ohouse's "전문가집들이" (professional home tours) section publishes spec sheets with brand names, prices, and SKUs. My Home magazine's print archive on Naver covers the same projects with longer interviews. Both are in Korean, but Chrome's auto-translate handles them well enough for a first pass. For high-end Korean architecture coverage, e-architect's South Korean section publishes English-language project breakdowns.

How Are Korean Designers Approaching 2026 Sustainability and Reuse?

Both aesthetics are quietly converging on a sustainability question — and the answers are different. Korean interior design firm Interior Design Seoul published its 2026 design philosophy framework, calling it the 4R Principle: Restore, Reconnect, Reinspire, Rejuvenate. The framework reads as a direct response to material waste in Korean renovation, which historically runs at roughly 220kg of construction debris per pyeong (Korea Ministry of Environment, 2025).

Hannam's Sustainability Pose

Hannam's sustainability story leans on longevity — using fewer, better materials that last 30+ years rather than reusing existing ones. Lime plaster, solid oak, real stone — these are renovate-once-and-leave-alone choices. The carbon math is real: a 2026 Korea Green Building Council study found that lime-plaster walls have lower lifecycle carbon than gypsum drywall when the building is occupied for 25+ years, mostly because plaster doesn't need refinishing while drywall typically gets repainted four to seven times in that window.

Seongsu's Sustainability Pose

Seongsu's sustainability story leans on reuse — exposing and celebrating existing materials rather than covering them. Polished concrete is "the floor that was already there." Exposed brick is "the wall the contractor was going to plaster over." Reclaimed wood comes from real demolitions, often in the same neighborhood. Translated from designer Lee Su-jin: "성수의 인더스트리얼 룩은 미적 선택이기 전에 환경적 선택이에요. 우리는 새 재료를 만들지 않고, 있는 재료를 보이게 만들어요." ("The Seongsu industrial look is an environmental choice before it's an aesthetic one. We don't create new materials. We make existing ones visible.")

Where the Two Converge

The 4R framework explicitly bridges both. "Restore" maps to Seongsu (reusing what's there). "Reconnect" maps to Hannam (linking interiors to art and natural materials). "Reinspire" and "Rejuvenate" are aesthetic-agnostic. In practice, the most sustainable 2026 renovations I've reviewed combine Seongsu's reuse impulse — keep the floor, expose the column, save the existing windows — with Hannam's longevity discipline — when you do replace, replace once with a material that won't need replacing again. That hybrid produces the lowest renovation waste numbers and, increasingly, the most awarded portfolios.

What Cultural Forces Are Driving the 2026 Split?

The Hannam/Seongsu divergence isn't just an aesthetic preference. It maps onto two real cultural forces in Korean society right now, and understanding them makes both styles easier to copy correctly.

Quiet Luxury and the K-Wealth Generation

The first force is what Korean media calls 조용한 럭셔리 (quiet luxury), tied to a generational shift in how affluent Koreans display wealth. In the 2010s, Korean luxury display was loud — Gucci logos, Mercedes G-Wagons, Hannam apartments with chandeliers and gold-leaf moldings. The 2020s reaction has been the opposite: invisibility, restraint, "stealth wealth." A March 2026 Hyundai Department Store consumer report found that 68% of Korean luxury buyers under 45 now prefer "logo-less" products over branded ones — up from 31% in 2019.

Hannam interior design tracks this exactly. The plaster walls, oak floors, and unbranded furniture are the residential equivalent of a logo-less Loro Piana sweater. They communicate wealth to people who recognize the materials and read as plain to those who don't. That's the point.

The Café Generation and Aesthetic Labor

The second force is what some Korean trend forecasters call 카페 세대 (the café generation). Korean café culture is uniquely intense — the country has over 100,000 active cafés (Korea SMBA, 2026), more per capita than any other country except possibly Italy. Many of those cafés function as remote workspaces, dating venues, content-creation studios, and informal community spaces. For Koreans aged 25–40, the café is often the most aesthetically considered space they regularly inhabit.

Seongsu interior design imports that café aesthetic directly into the home. The exposed brick, the industrial pendants, the communal table, the visible coffee bar — these are café cues, deployed residentially. Once you see this, you can't unsee it: a Seongsu apartment is a café you sleep in. That's why the look photographs so well, why it works for content creators, and why it costs less to execute well — café design has been refining the formula for over a decade.

Why Both Will Persist

Both cultural forces are getting stronger, not weaker. Korean wealth is concentrating in fewer hands (top 10% household wealth share rose to 58% in 2026, per Bank of Korea), which sustains demand for Hannam-style stealth-luxury renovations. Korean café density continues to grow, and content-creator economy continues to expand, which sustains demand for Seongsu-style aestheticized residential spaces. The split isn't a phase. It's structural.

Frequently Asked Questions

Is Hannam-dong style or Seongsu-dong style more popular in 2026?

Both are growing, but Seongsu is growing faster. Per Ohouse's February 2026 trend data, Hannam-tagged saves grew 41% YoY while Seongsu-tagged saves grew 67% YoY. The absolute volume still favors Hannam — about 2.3M tagged saves to Seongsu's 1.7M — but Seongsu is closing the gap. Among users under 35, Seongsu has already overtaken Hannam in saves as of Q1 2026.

Can I get the Hannam look on a budget?

Sort of. The single biggest cost driver in Hannam style is the oak floor and the lime-plaster walls — together they're about 35% of total finish cost. You can fake the oak with high-quality engineered laminate at roughly 40% of the cost (₩72,000–₩110,000 per pyeong, ~$53–$81/3.3m²) but the plaster has no convincing budget substitute. A satin-finish wall paint in the right warm-white tone (try 노루페인트's "오트밀" at ₩68,000/4L, ~$50) gets you maybe 70% of the way there for under 10% of the cost.

Which style works better in older Korean apartments (구축)?

Seongsu, almost universally. Older Korean apartments (older than ~2005) often have low ceilings, structural columns mid-room, and exposed plumbing risers — all of which read as bugs in Hannam-style renovations and features in Seongsu ones. Per Zipdoc's 2026 renovation data, 64% of Seongsu-style renovations happen in pre-2005 buildings versus 31% of Hannam-style.

Do these aesthetics work outside Korea?

Yes, with adaptation. Hannam style translates almost directly to Western markets — it's adjacent to what Americans call "warm minimalism" or "European refined." Seongsu translates with one tweak: Korean industrial style leans warmer (more wood, more leather) than American industrial style (more metal, more black). If you're copying a Seongsu look in a US apartment, lean into the warm wood and skip the heaviest black metal moments, or it'll read as a 2014 Brooklyn café.

How long does each renovation take?

Hannam-style full-apartment renovations take 8–12 weeks per Zipdoc's 2026 data, mostly because the plaster, millwork, and stone work each have multi-week curing or fabrication windows. Seongsu-style full renovations take 5–8 weeks because raw materials need less finishing time. Both are longer than American expectations — Korean renovation labor runs at roughly 70% of American throughput per square foot due to elevator constraints in Korean apartment buildings.

Which style holds resale value better in 2026?

In Hannam-dong itself, Hannam-style renovations command an 8–12% premium on resale, per a Q1 2026 KB Real Estate listings study. In Seongsu-dong, Seongsu-style renovations command a 5–7% premium. Cross-pollinated renovations — Seongsu-style finishes in a Hannam apartment, or vice versa — actually depress prices by roughly 3–4% because they read as mismatched to the neighborhood. Translated lesson: match the aesthetic to the building stock and the neighborhood, not just to your personal taste, if resale matters. In neutral neighborhoods like Mapo, Yongsan, and most of Seongdong outside the core Seongsu blocks, the 80/20 Hannam-shell-Seongsu-soul hybrid resells best, gaining 6–9% on average per the same study.
