Why walk-up apartment interior design
needs a specialist eye.
Walk-up apartments — typically 3 to 5 storey low-rise residential buildings built before 1980, with no lift — are a distinctive piece of Singapore's housing heritage. They have charm: generous ceiling heights, original terrazzo, solid brick walls, and layouts that often reward thoughtful re-planning. They also have constraints: constrained floor plates, aging electrical and plumbing, restricted natural light, and access limitations for materials.
MET Interior specialises in modernising these spaces while preserving the character that makes walk-ups special. Our HDB-registered, BCA-licensed team handles M&E upgrades, structural assessment, and (where applicable) URA conservation submissions end-to-end.
MET Interior is an HDB-registered, BCA-licensed Singapore interior design studio specialising in walk-up apartment renovation. Walk-ups — typically 3 to 5 storey pre-1980s flats with no lift — have constrained layouts, aging M&E, and restricted natural light. We have renovated walk-ups across Tiong Bahru, Joo Chiat, Tanjong Katong, Serangoon, and Geylang since 2011, modernising interiors while preserving the architectural character.
The Specialist Lens
Common walk-up challenges
Narrow layouts
Small kitchens and tight rooms can feel restrictive. Careful planning opens them up without hacking.
Aging infrastructure
Old wiring, plumbing, and flooring often need upgrading. We handle it safely and to code.
Ventilation & light
Dark corners reduce comfort. Mirrors, glass, and lighter palettes transform the feel.
Storage constraints
Clutter builds up without smart planning. Built-ins and hidden storage are essential.

Walk-up vs HDB vs condo — what is different
| Walk-up | HDB | Condo | |
|---|---|---|---|
| Building age | Pre-1980 typically | 1970s – 2020s | 1970s – 2020s |
| Lift access | None — walk-up only | Lift to every floor | Lift to every floor |
| M&E condition | Often needs full replacement | Usually sound in BTOs, variable in resales | Sound in new launches, variable in resales |
| Approval authority | HDB walk-up: HDB. Private walk-up: MCST | HDB | MCST |
| Typical cost range | $30k – $120k (M&E-dependent) | $28k – $80k | $30k – $100k |
| Typical timeline | 8–14 weeks | 6–12 weeks | 8–12 weeks |
| Conservation considerations | Sometimes (Tiong Bahru, Joo Chiat) | None typically | None typically |
Indicative ranges based on MET Interior projects. Walk-up costs are highly dependent on the condition of existing electrical and plumbing services.

Walk-up apartment renovation cost Singapore
Walk-up apartment renovations in Singapore typically cost between $30,000 and $120,000 for full refurbishments, with light cosmetic refreshes starting lower. The single biggest cost driver is M&E condition — older walk-ups almost always require full electrical rewiring (to current IEC 60364 / SS 638 standards) and often need re-piping too. This alone can add $15,000–$30,000.
Secondary cost drivers are hacking scope (old tile removal, plaster repair, waterproofing), carpentry (walk-ups have less standard dimensions, so custom carpentry is usually required), and access — no lift means materials are carried up by hand, which adds 10–20% to labour.
Every MET Interior quote is itemised line-by-line with a separate M&E assessment upfront, so you know what you are signing up for before works begin.
Conservation walk-ups — Tiong Bahru, Joo Chiat, Emerald Hill
Certain walk-up areas in Singapore fall under URA conservation rules: Tiong Bahru (the pre-war Art Deco SIT flats), Joo Chiat and Tanjong Katong shophouses, Emerald Hill, and parts of Little India. Conservation means the facade, certain internal architectural elements (original terrazzo, specific doors or windows, structural layouts) and sometimes the roof profile are protected by URA.
Interior works that do not affect the conserved elements usually proceed with standard approval. Works affecting facade, windows, or structural layout require URA conservation submission via a conservation-experienced Architect — add 2–4 months of approval time.
We work with a panel of conservation Architects and have delivered walk-up renovations across Tiong Bahru, Joo Chiat, Tanjong Katong, and Geylang.
Modernising walk-ups — light, ventilation, and layout
The three biggest design wins in walk-up renovation are light, ventilation, and layout flow. Strategic moves we use repeatedly: interior glass partitions to borrow light between rooms, lighter material palette (white walls, pale timber, reflective surfaces) to amplify what light there is, ceiling fans for cross-ventilation (Singapore walk-ups were designed pre-aircon), and where structurally possible, opening the kitchen to the living area.
Where roof access exists and the unit is top-floor, skylights can transform the space — subject to structural review and waterproofing detailing. We have introduced skylights in several top-floor walk-up projects with 10-year waterproofing warranties.
The goal is never to erase the character — the terrazzo, the ceiling heights, the original layouts — but to modernise around it.

Common questions
How much does walk-up apartment renovation cost in Singapore?
Walk-up renovations typically range $30,000–$120,000 for full refurbishments, with light cosmetic refreshes starting lower. Costs depend heavily on M&E condition — older electricals and plumbing often need full replacement, which adds $15,000–$30,000.
What permits do walk-ups need for renovation?
Walk-ups classified as HDB walk-ups require an HDB Renovation Permit. Privately-owned walk-ups governed by a Management Corporation need MCST approval. Structural works require BCA submission via a Qualified Person. MET Interior handles all permits.
How long does a walk-up renovation take?
Walk-up renovations typically run 8–14 weeks on-site. Older units with heavy M&E rework sit at the longer end because full rewiring, re-piping, and sometimes re-flooring are required. Design development adds 3–5 weeks beforehand. Access constraints (no lift) can add 1–2 weeks for material hoisting.
Can walk-up layouts be opened up?
Non-load-bearing walls can usually be removed subject to structural assessment. Older walk-ups often have solid brick or reinforced concrete structural walls that cannot be touched — we survey and confirm before quoting. Opening up to the kitchen or combining rooms is a common and successful move.
How do you improve ventilation and light in walk-ups?
Strategic moves: open-tread stairs (where applicable), interior glass partitions, lighter material palette, mirror placements for light bounce, ceiling fans, and enhanced lighting design. Where roof access exists, we can introduce skylights subject to structural and waterproofing review.
Can I renovate a heritage or conservation walk-up?
Yes — but URA conservation rules may apply to the facade and certain architectural elements. Tiong Bahru, Joo Chiat, and Emerald Hill are common conservation areas. We work with a panel of conservation-experienced Architects when URA conservation approval is required.
How much does it cost to renovate a walk-up apartment in Singapore?
Costs vary by size and scope — most projects range from $10,000 for cosmetic refreshes to $500,000+ for full structural remodels. Every quote we issue is line-itemised.
Do I need building permits for walk-up renovation?
Yes — certain structural, electrical, or plumbing works require approval. As a licensed firm, we handle all necessary submissions and permits for you.
How long does renovation typically take?
8–12 weeks on average, depending on the extent of renovation and the condition of the apartment (electrical rewiring, plumbing, roof works add time).
Can you modernise old walk-up apartments?
Absolutely. We specialise in upgrading old layouts, electrical systems, and plumbing — while maintaining the character that makes walk-ups unique.
What storage solutions work best in walk-ups?
Custom carpentry, built-in wardrobes, under-bed storage, and modular shelving. Every inch matters, and we plan storage into the architecture rather than bolting it on.
