How Much Does Korean 셀프인테리어 Actually Cost? A Room-by-Room Budget Guide

Quick Answer

A full 셀프인테리어 (self-interior) renovation of a typical 24-pyeong Korean apartment costs 3,000,000-8,000,000 won when done DIY — compared to 15,000,000-40,000,000 won for the same work through a professional 인테리어 업체 (interior contractor), representing savings of 50-75% by doing the labor yourself
The biggest cost differences between DIY and professional are in labor-intensive trades — 도배 (wallpapering) saves 60-70% DIY, 페인트 (painting) saves 70-80% DIY, and 조명 (lighting) installation saves 40-60% DIY, while plumbing and electrical work should almost always be left to professionals due to Korean building codes and safety requirements
Korean apartment renovation costs follow a predictable pattern by room — kitchens are the most expensive room to renovate (4,000,000-15,000,000 won professional, 2,000,000-6,000,000 won partial-DIY), followed by bathrooms (3,000,000-10,000,000 won professional), while bedrooms and living rooms are the most DIY-friendly (500,000-2,000,000 won per room)
The single most important cost-saving strategy is 분리 발주 (split ordering) — hiring individual tradespeople for specific tasks (electrician, plumber, tiler) rather than paying a single 인테리어 업체 that marks up each trade by 20-40%, which alone can save 2,000,000-5,000,000 won on a full apartment renovation

The Korean Self-Interior Cost Reality

Let's get the numbers straight. Korean interior renovation costs have risen significantly in recent years. According to industry data from 집닥 (Zipdoc, Korea's largest interior comparison platform) and 아자닷컴 (AJD, Korea's 25-year-old interior cost database), the 2025 average costs for apartment renovation are:

Full professional renovation (올수리/턴키) by평수:

10평 (studio/officetel): 8,000,000-15,000,000 won
20평 (small apartment): 12,000,000-25,000,000 won
24평 (standard apartment): 15,000,000-30,000,000 won
30평 (mid-size apartment): 20,000,000-40,000,000 won
40평 (large apartment): 30,000,000-60,000,000 won
50평 (premium apartment): 40,000,000-80,000,000+ won

These numbers include labor, materials, design fees, and project management. The 평당 (per-pyeong) cost ranges from 150,000-300,000 won for basic renovation to 400,000-600,000+ won for premium specifications.

Now here's where 셀프인테리어 changes the math.

When you do the labor yourself on tasks that don't require licensed professionals, the cost drops to materials only. And materials — wallpaper, paint, flooring, lighting fixtures, hardware — cost roughly 30-40% of the total professional bill. The other 60-70% is labor, overhead, and markup.

A 24-pyeong apartment that costs 20,000,000 won through a contractor can be renovated for 5,000,000-8,000,000 won in a hybrid approach: DIY where possible, hire specialists only for plumbing, electrical, and tiling. This hybrid model — called 반셀프 (half-self) or 분리 발주 (split ordering) in Korean interior communities — is how experienced Korean DIY-ers actually operate.

Room-by-Room Cost Breakdown

거실 (Living Room) — The High-Impact, Low-Cost Win

The living room is the easiest room to transform on a budget because the main interventions — wallpaper, paint, lighting, and styling — are all highly DIY-friendly.

Professional renovation cost: 3,000,000-8,000,000 won 셀프인테리어 cost: 500,000-2,500,000 won

Item	Professional	셀프 (DIY)	Savings
도배 (wallpaper)	400,000-800,000 won	100,000-250,000 won	60-70%
장판/바닥재 (flooring)	600,000-1,500,000 won	300,000-700,000 won (materials + hired installer)	50%
조명 교체 (lighting)	300,000-1,000,000 won	100,000-400,000 won	60%
페인트 (painting, accent wall)	200,000-500,000 won	50,000-150,000 won	70%
몰딩 교체 (trim/molding)	200,000-500,000 won	80,000-200,000 won	60%
커튼/블라인드 (curtains)	300,000-800,000 won	150,000-400,000 won	50%

What to DIY: Wallpaper (see our 셀프 도배 guide), painting, lighting fixture swaps, curtain installation, furniture arrangement, styling What to hire out: Flooring installation (장판 시공 requires skill with adhesives and seaming), electrical work if adding new outlets or circuits

High-impact budget moves for the living room:

Fresh wallpaper on all walls: 100,000-250,000 won for materials. Biggest visual bang for the lowest cost
Swap the ceiling light from fluorescent to modern LED: 50,000-200,000 won. Changes the entire room's mood
Add indirect lighting (간접조명) behind the TV or sofa: 30,000-100,000 won for LED strips. The single most "Korean" lighting upgrade you can make
Paint one accent wall in a 2025 trend color like 모카 무스: 30,000-50,000 won for paint. See our Korean color palette guide for color selection

침실 (Bedroom) — The Easiest Room to Transform

Bedrooms are small, have fewer fixtures, and the main costs are bedding and wallpaper — both extremely DIY-friendly.

Professional renovation cost: 2,000,000-5,000,000 won 셀프인테리어 cost: 300,000-1,500,000 won

Item	Professional	셀프 (DIY)	Savings
도배 (wallpaper)	200,000-500,000 won	60,000-150,000 won	65-70%
장판 (flooring)	300,000-700,000 won	150,000-350,000 won	50%
조명 (lighting)	150,000-400,000 won	50,000-150,000 won	65%
붙박이장 정리/시트지 (closet refresh)	200,000-500,000 won	30,000-100,000 won	80%

What to DIY: Everything except flooring installation. Wallpaper, lighting, closet organization, furniture, bedding, styling are all beginner-friendly What to hire out: Flooring if replacing (consider just cleaning and refreshing existing flooring to save entirely)

For bedroom-specific design guidance, see our Korean bedroom design guide.

주방 (Kitchen) — The Expensive One

Kitchens are the most expensive room to renovate because they involve plumbing, cabinetry, appliances, and specialized waterproofing — most of which require professional skills.

Professional renovation cost: 4,000,000-15,000,000 won 반셀프 (hybrid) cost: 2,000,000-6,000,000 won

Item	Professional	반셀프 (Hybrid)	Savings
싱크대/상부장 교체 (cabinets)	2,000,000-6,000,000 won	1,500,000-4,000,000 won (buy direct, hire installer)	25-35%
상판 교체 (countertop)	500,000-2,000,000 won	400,000-1,500,000 won	20-25%
타일 시공 (backsplash tile)	300,000-800,000 won	100,000-300,000 won (adhesive tile sheets DIY)	60%
수전 교체 (faucet replacement)	150,000-400,000 won	80,000-200,000 won (DIY with YouTube)	50%
조명 (lighting)	200,000-500,000 won	80,000-200,000 won	60%
페인트/시트지 (cabinet painting/film)	300,000-800,000 won	50,000-200,000 won	75%

The biggest kitchen savings hack: Instead of replacing cabinets (2,000,000-6,000,000 won), apply adhesive vinyl film (시트지) to existing cabinet doors. Cost: 30,000-100,000 won in materials. On 오늘의집, thousands of Korean homeowners have documented this transformation. The visual change is dramatic — outdated wood-grain cabinets become sleek white or matte gray — at 5% of the replacement cost.

What to DIY: Cabinet film wrapping, backsplash tile sheets (접착식 타일), painting, lighting, small hardware replacement (handles, knobs), open shelving installation What to hire out: Sink and cabinet installation, countertop replacement, plumbing modifications, gas line work (required by law for gas range installation)

For detailed kitchen renovation strategies, see our Korean kitchen renovation budget guide.

욕실 (Bathroom) — The Hardest to DIY

Korean bathrooms are 습식 (wet rooms) with floor drains, waterproof walls, and integrated shower areas. Renovating them involves waterproofing, tiling, plumbing, and electrical work — all requiring professional expertise.

Professional renovation cost: 3,000,000-10,000,000 won per bathroom 반셀프 cost: 2,000,000-6,000,000 won per bathroom

Item	Professional	반셀프 (Hybrid)	Savings
타일 시공 (tile work)	1,000,000-3,000,000 won	800,000-2,000,000 won (buy tile direct, hire tiler)	20-35%
방수 시공 (waterproofing)	500,000-1,500,000 won	500,000-1,500,000 won (always hire professional)	0%
위생도기 (toilet, sink)	500,000-2,000,000 won	300,000-1,000,000 won (buy direct, hire installer)	40%
수전/수도 (faucets/plumbing)	300,000-800,000 won	200,000-500,000 won	35%
환풍기/조명 (ventilation/lighting)	200,000-500,000 won	100,000-250,000 won	50%
욕실장 (vanity/cabinet)	200,000-600,000 won	100,000-300,000 won	50%

What to DIY: Painting bathroom cabinets, replacing shower accessories (shower head, towel bars), adding storage solutions, replacing the mirror, installing adhesive tile stickers on non-wet areas What to NEVER DIY: Waterproofing (방수). A failed waterproofing job will leak into the apartment below you and can result in damage claims of 5,000,000-20,000,000+ won. Always hire a professional for waterproofing

베란다 (Veranda/Balcony) — The Hidden Value Play

The veranda conversion offers the best cost-to-impact ratio in Korean apartments because you're creating new usable space from previously dead space.

Professional conversion cost: 2,000,000-10,000,000 won 셀프 conversion cost: 300,000-3,000,000 won

Item	Professional	셀프 (DIY)	Savings
단열 시공 (insulation)	500,000-1,500,000 won	200,000-500,000 won (DIY spray foam/panels)	60%
바닥 마감 (floor finishing)	300,000-800,000 won	100,000-300,000 won (interlocking tiles or LVT)	65%
페인트/벽지 (wall finish)	200,000-500,000 won	50,000-150,000 won	70%
조명 (lighting)	150,000-400,000 won	50,000-150,000 won	65%
가구/소품 (furniture/accessories)	500,000-2,000,000 won	300,000-1,000,000 won	40%

For detailed veranda conversion strategies, see our Korean veranda conversion guide.

현관 (Entryway) — Small Budget, Big Impression

The Korean 현관 is the shoe-removal zone — the threshold between outside and inside. It's small (usually 1-2 square meters) but sets the tone for the entire apartment.

Professional renovation cost: 500,000-2,000,000 won 셀프 cost: 100,000-500,000 won

Item	Professional	셀프 (DIY)	Savings
타일 스티커/시트 (floor sticker)	150,000-400,000 won	30,000-100,000 won	75%
신발장 정리/교체 (shoe cabinet)	200,000-600,000 won	50,000-200,000 won	70%
벽면 페인트/벽지 (wall finish)	100,000-300,000 won	30,000-80,000 won	70%
조명 (lighting)	100,000-300,000 won	30,000-100,000 won	65%
거울/소품 (mirror/accessories)	50,000-200,000 won	30,000-100,000 won	40%

The 분리 발주 Strategy: How to Save 25-40%

분리 발주 means "split ordering" — hiring individual specialists for each trade instead of paying a single interior company (인테리어 업체/턴키 업체) to manage everything.

How the 턴키 Model Works (And Why It Costs More)

When you hire a Korean 인테리어 업체 for a turnkey renovation:

They visit your apartment and create a design plan
They subcontract each trade: 도배사 (wallpaper installer), 타일공 (tiler), 배관공 (plumber), 전기공 (electrician), 목수 (carpenter)
They purchase materials on your behalf
They project-manage the schedule and quality

The markup structure:

Material markup: 15-30% above retail
Labor coordination fee: 10-20% of labor costs
Design/management fee: 5-15% of total
Profit margin: 10-20%

Total overhead vs. direct hiring: approximately 25-40% more expensive.

How 분리 발주 Works

You become your own project manager:

Design the renovation yourself (using 오늘의집 for inspiration, see our best Korean interior apps guide)
Purchase materials directly from suppliers (방산시장, online retailers, 쿠팡)
Hire individual tradespeople through platforms like 숨고 (Soomgo), 미소 (Miso), or 오늘의집 시공 서비스
Schedule the work yourself, managing the sequence of trades

The Standard Korean Renovation Sequence

If you're managing your own renovation, the work must happen in this order:

철거 (demolition): Remove old fixtures, wallpaper, flooring as needed
배관 (plumbing): Any pipe modifications or replacements
전기 (electrical): New wiring, outlet additions, switch relocations
방수 (waterproofing): Bathroom waterproofing (must cure before tiling)
타일 (tiling): Bathroom and kitchen tile work
목공 (carpentry): Built-in shelving, crown molding, trim
도배 (wallpaper): Wall finishing
장판/바닥재 (flooring): Floor installation
조명/마감 (lighting/finishing): Install light fixtures, switch plates, final details
입주 청소 (move-in cleaning): Professional deep clean

Getting this order wrong causes expensive rework. Example: wallpapering before electrical work means the electrician cuts holes in your new wallpaper. Flooring before tiling means tile adhesive drips on your new floor.

How Much Does 분리 발주 Actually Save?

Example: 24-pyeong apartment full renovation

Component	턴키 업체	분리 발주	Savings
도배 + 장판	2,500,000 won	1,800,000 won	700,000 won
주방	6,000,000 won	4,200,000 won	1,800,000 won
욕실 x 2	8,000,000 won	5,600,000 won	2,400,000 won
전기/조명	1,500,000 won	1,000,000 won	500,000 won
목공	1,000,000 won	700,000 won	300,000 won
기타	1,000,000 won	700,000 won	300,000 won
Total	20,000,000 won	14,000,000 won	6,000,000 won (30%)

The 30% savings comes at the cost of your time managing the project — approximately 20-40 hours over a 2-4 week renovation period. For many Korean homeowners, this trade-off makes sense.

The Realistic Cost of Common셀프 Projects

Not doing a full renovation? Here are the costs for the most popular individual 셀프인테리어 projects.

셀프 도배 (DIY Wallpaper) — Full Apartment

Apartment Size	Materials Cost	Time Investment
10평	80,000-150,000 won	1-2 weekends
20평	150,000-300,000 won	2-3 weekends
24평	200,000-400,000 won	2-3 weekends
30평	250,000-500,000 won	3-4 weekends

Professional comparison: 3-5x these amounts. Wallpapering is the highest-savings DIY project.

셀프 페인트 (DIY Painting) — Accent Walls or Full Room

Scope	Materials Cost	Time Investment
Single accent wall	30,000-60,000 won	3-4 hours
One room (all walls)	80,000-150,000 won	1 day
Full apartment	200,000-400,000 won	2-3 days

Professional comparison: Approximately 600,000-1,800,000 won for a full apartment. Painting is the simplest and cheapest DIY project with the second-highest visual impact after wallpaper.

Recommended Korean paint brands:

삼화 페인트 (Samhwa): Korea's most popular interior paint. The "에브리데이" line is budget-friendly at approximately 30,000-40,000 won per 4L can
노루 페인트 (Noroo): Extensive color range. The 코스모스 line is popular for interiors
벤자민무어 한국 (Benjamin Moore Korea): Premium option. 70,000-100,000 won per gallon but superior coverage and color depth

셀프 조명 교체 (DIY Lighting Swap)

Type	Product Cost	Time Investment
Ceiling light replacement (방등)	30,000-200,000 won per fixture	30 minutes per fixture
LED strip indirect lighting	20,000-50,000 won per meter	1-2 hours per room
Pendant light installation	50,000-300,000 won per fixture	1 hour per fixture
Full apartment lighting upgrade	200,000-800,000 won	1 weekend

Professional comparison: 500,000-2,000,000 won installed. Lighting swaps are surprisingly easy — most Korean ceiling fixtures use standardized mounting brackets.

시트지 (Adhesive Film) — Cabinet and Furniture Refresh

Scope	Materials Cost	Time Investment
Kitchen cabinet doors	30,000-80,000 won	4-6 hours
Bathroom vanity	15,000-30,000 won	1-2 hours
Furniture piece (desk, shelf)	10,000-30,000 won	1-2 hours

Professional comparison: 300,000-800,000 won for kitchen cabinets. Adhesive film (시트지) is one of the most popular셀프 projects on 오늘의집 because the before/after impact is dramatic and the cost is minimal.

Hidden Costs Most Beginners Miss

1. 폐기물 처리 (Waste Disposal)

Old wallpaper, flooring, fixtures, and construction debris need proper disposal. Korean apartments require authorized waste disposal:

건설 폐기물 스티커 (construction waste sticker): Purchased from your local 구청 (district office). Cost varies by municipality: typically 5,000-20,000 won per large bag
대형 폐기물 처리 (bulky waste): Old furniture, fixtures, appliances. Applied for online through your district office: 3,000-30,000 won per item
Budget: Add 50,000-200,000 won for waste disposal to any renovation budget

2. 보양 (Protection)

Protecting floors, fixtures, and surfaces you're NOT renovating. Protection materials (비닐 시트, 마스킹 테이프, 골판지) cost 30,000-80,000 won and are essential for preventing damage to existing finishes during renovation.

3. 실패 여유분 (Mistake Materials)

First-time DIY-ers waste materials. Budget an extra 10-15% for:

Wallpaper strips that go crooked and need replacing
Paint that needs a second coat (it usually does)
Adhesive film that tears during application
Flooring pieces cut to wrong dimensions

4. 공구 (Tools)

If this is your first셀프인테리어 project, you need tools. A starter kit costs:

Basic hand tools (screwdrivers, hammer, level, measuring tape): 30,000-60,000 won
도배 tools (smoothing brush, utility knife, trim guide): 30,000-80,000 won
페인트 tools (rollers, brushes, trays, tape): 20,000-50,000 won
Power drill (충전드릴 — essential for shelving, curtain rods, etc.): 50,000-150,000 won
Total starter toolkit: 130,000-340,000 won

These are one-time costs that amortize across all future projects. By your third project, the per-project tool cost approaches zero.

5. 이사 비용 or 임시 거주 (Temporary Living)

For major renovations (full apartment 올수리), you may need to move out temporarily. This is common in Korea:

Temporary housing (임시 거주): Airbnb, goshiwon, or staying with family. Budget: 500,000-2,000,000 won for 2-4 weeks
Furniture storage (짐 보관): Storage services for your belongings during renovation. Budget: 200,000-500,000 won per month

For partial renovations (one or two rooms), you can usually live in the apartment while working room by room.

The Smartest Way to Allocate Your Budget

The 50-30-20 Renovation Budget Rule

Korean interior communities have converged on this allocation:

50% — Kitchen and Bathroom These rooms have the highest cost and the highest impact on daily quality of life. They also affect resale value the most. Spend half your budget here.

30% — Living Room and Bedrooms High visual impact, mostly achievable through DIY. Wallpaper, paint, lighting, and furniture do most of the work.

20% — Veranda, Entryway, and Finishing Touches Smaller spaces that round out the renovation. Often the most satisfying projects because they're quick wins.

Budget-First vs. Impact-First Approach

If you have 1,000,000 won: Focus entirely on wallpaper + lighting + paint. These three changes across the whole apartment transform the visual experience for under 1 million won. This is the minimum effective dose of셀프인테리어.

If you have 3,000,000 won: Add flooring to one or two rooms, a kitchen cabinet film wrap, and basic veranda conversion. The apartment starts to feel comprehensively refreshed.

If you have 5,000,000-8,000,000 won: Full hybrid renovation — DIY where you can, hire specialists for bathroom waterproofing, kitchen plumbing, and flooring installation. This budget covers a genuine transformation of a 24-pyeong apartment.

If you have 10,000,000-15,000,000 won: Everything above plus professional kitchen and bathroom renovation (분리 발주 to save 25-30% vs. turnkey). At this budget, you're approaching professional-quality results throughout.

Where to Buy Materials (And What to Pay)

Photo by siala on Pixabay

Online Retailers

Platform	Best For	Price Level
쿠팡 (Coupang)	Everything; fastest delivery	Mid-range
오늘의집 (Today's House)	Curated selections, reviews, inspiration	Mid-premium
월플랜 (Wallplan)	Wallpaper specialist, pre-pasted options	Budget-mid
룸스토어 (Roomstore)	Wallpaper, flooring, adhesive film	Budget
인터파크/G마켓	Price comparison, deals	Budget

Offline Markets

Location	Best For	Price Level
방산시장 (Bangsan Market, Seoul)	Wallpaper, fabric, decorative materials	Wholesale (cheapest)
노량진 인테리어 자재 상가	Construction materials, tiles, fixtures	Wholesale
다이소 (Daiso)	Small hardware, organization, tools	Budget
이케아 (IKEA)	Furniture, storage, lighting, textiles	Mid-range
한샘 디자인파크	Kitchens, furniture, full-room solutions	Premium

The 방산시장 strategy: Seoul's Bangsan Market in Euljiro is the Korean interior materials mecca. Wallpaper sold here is 30-50% cheaper than online retail. The catch: you need to know what you want before going (it's overwhelming) and most stalls have minimum order quantities. Visit once to browse and sample, then return to buy.

Month-by-Month Payment Strategy

Many Korean셀프인테리어 practitioners don't renovate all at once. They spread the project over months to manage cash flow:

Month 1: 도배 + 페인트 (300,000-500,000 won) The highest-impact, lowest-cost projects. Fresh walls change the entire apartment's feel immediately.

Month 2: 조명 교체 (200,000-500,000 won) Swap out fluorescent ceiling lights for modern LED fixtures. Add indirect lighting. The second-biggest mood change.

Month 3: 주방 시트지 + 악세서리 (100,000-300,000 won) Wrap kitchen cabinets in new adhesive film. Replace drawer handles. Add under-cabinet lighting. Kitchen transformation without major renovation.

Month 4: 베란다 전환 (300,000-800,000 won) Convert one veranda into usable space with furniture, lighting, and basic finishing.

Month 5: 바닥재 (500,000-1,500,000 won) Replace or refinish flooring in the most-used rooms. This is the first month where you might hire a professional installer.

Month 6: 욕실 + 마무리 (1,000,000-3,000,000 won) Bathroom refresh — new accessories, mirror, paint, and possibly professional tile work. Entryway finishing. Final touches throughout.

Total over 6 months: 2,400,000-6,600,000 won — a complete apartment transformation paid for gradually without a single large outlay.

Cost Comparison: Seoul vs. Other Korean Cities

Renovation costs vary significantly by location. Seoul is the most expensive; smaller cities can be 20-40% cheaper.

City/Region	Cost Index (Seoul = 100)
서울 (Seoul)	100
경기 (Gyeonggi)	85-95
인천 (Incheon)	80-90
부산 (Busan)	75-85
대구 (Daegu)	70-80
대전 (Daejeon)	70-80
광주 (Gwangju)	65-75
지방 소도시 (Small cities)	60-70

The difference is primarily in labor costs — materials cost roughly the same nationwide (especially when ordering online). Tradespeople in Seoul charge 20-50% more than in smaller cities due to higher living costs and demand.

Frequently Asked Questions

How much should I budget for a complete 셀프인테리어 renovation of a 24-pyeong Korean apartment?

For a full셀프인테리어 transformation including wallpaper, paint, lighting, kitchen refresh, and basic styling — but excluding major bathroom work and professional-only trades — budget 3,000,000-5,000,000 won. For a hybrid approach (반셀프) that includes professional bathroom renovation and flooring installation, budget 5,000,000-8,000,000 won. This compares to 15,000,000-30,000,000 won for a full professional turnkey renovation. The 50-75% savings come from doing labor-intensive but skill-accessible work yourself (wallpaper, painting, lighting, cabinet wrapping, furniture assembly) while hiring specialists only for trades that require licensing or specialized tools (plumbing, electrical, waterproofing, tiling).

What is the most cost-effective셀프 인테리어 project for maximum visual impact?

Wallpapering (셀프 도배) delivers the highest visual transformation per won spent. Fresh wallpaper throughout a 24-pyeong apartment costs 200,000-400,000 won in materials and transforms every room simultaneously. The second-highest impact project is lighting — swapping fluorescent ceiling fixtures for modern LED lights and adding indirect lighting (간접조명) for 200,000-500,000 won changes the entire apartment's atmosphere. Together, these two projects under 1,000,000 won will make more visual difference than any single expensive renovation project.

Should I use the 분리 발주 (split ordering) method or hire a turnkey contractor?

분리 발주 saves 25-40% compared to turnkey contractors but requires you to manage the project yourself — scheduling trades, purchasing materials, resolving problems. It's best for: people who have flexible schedules during renovation, those who have done at least one renovation before, and anyone willing to invest 20-40 hours of project management time over 2-4 weeks. Turnkey is better for: first-time renovators doing major structural work, people who can't take time off work, and situations where kitchen and bathroom plumbing are being completely reconfigured. A middle ground: hire a turnkey contractor for kitchen/bathroom only, and self-manage (분리 발주 or full DIY) for living room, bedrooms, and veranda.

How much do Korean apartment renovation costs vary by apartment age?

Older apartments (구축, typically 15+ years) cost significantly more to renovate than newer ones (신축, under 10 years). The reason: older Korean apartments often need plumbing replacement (배관 교체, 500,000-1,000,000 won additional), electrical panel upgrades (분전반 교체, 200,000-500,000 won), and more extensive wall repair before wallpapering. A 24-pyeong 구축 apartment renovation typically costs 20-40% more than the same work in a newer building. Budget an extra 2,000,000-5,000,000 won for hidden costs in apartments over 20 years old, particularly for plumbing and waterproofing that may have degraded.

What Korean apps and platforms help me estimate renovation costs?

The best cost estimation tools in Korean include: 집닥 (Zipdoc) at zipdoc.co.kr — a free interior cost calculator where you input your apartment size, age, and desired work scope and receive estimated price ranges based on their database of completed projects. 오늘의집 시공 서비스 helps you compare quotes from multiple contractors. 숨고 (Soomgo) connects you with individual tradespeople and shows average pricing for each trade in your area. For DIY material pricing, 쿠팡 and 오늘의집 allow filtering by category to compare material costs before purchasing.
