HDB interior design in Singapore

Practical, well-planned HDB interior design — and the renovation that builds it. As a direct renovation contractor with our own in-house team, we take HDB flats (and condominiums) from layout and carpentry to finishes under one turnkey scope, so you deal with the people doing the work and pay no middleman markup on labour.

Design and build, under one team

Most interior design in Singapore is sold by designers who then subcontract the building work and add their margin on top. We work the other way round: we're the contractor, with our own carpenters and trades, so the people who plan your flat are the people who build it. That means clearer accountability, fewer hand-offs, and more of your budget reaching the actual materials and finishes.

It also makes a genuinely turnkey renovation possible — space planning, carpentry, tiling, electrical, plumbing, painting and finishing coordinated into one itemised quotation, from an empty or dated flat to a move-in-ready home.

What it covers

What HDB interior design includes

Space planning & layout

Reworking the floor plan around how you actually live — open-concept living and kitchen, walkways, and where walls (non-structural) can come down, within HDB's guidelines.

Carpentry & built-ins

The bulk of most HDB interiors: built-in wardrobes, kitchen cabinets, TV feature walls, shoe cabinets and study desks — made to fit by our own carpenters.

Kitchens & wardrobes

Practical, hard-wearing kitchens and storage — cabinet layout, worktops, tall units and soft-close fittings sized to a compact flat.

Wet works & waterproofing

Bathrooms and kitchens done properly — hacking, membrane waterproofing, tiling and sanitary ware, so leaks don't reach the unit below.

Electrical & lighting

Rewiring, extra power points, distribution board and a lighting plan — the layer that decides how a finished flat actually feels to use.

Finishes & feature walls

Painting, flooring, false ceilings and cornices, plus feature walls — including the WPC fluted panelling we're known for.

By flat type

3-room, 4-room and 5-room HDB

Every flat type asks for a different plan. A BTO starts bare, so the budget goes to carpentry and finishes; a resale flat is lived-in and often needs hacking, rewiring or re-piping first. Here's where each one usually starts.

3-room HDB interior design

3-room HDB

Around 60–70 sqm — every centimetre counts. Open-plan living, slim built-ins and light finishes to keep a compact flat feeling airy.

4-room HDB interior design

4-room HDB

The most common BTO and resale layout (~90 sqm) — the balance point between storage, a proper kitchen and a comfortable living area.

5-room & executive interior design

5-room & executive

Larger flats (~110–130 sqm) with room for a study, a glass partition or a walk-in wardrobe — like our Tampines St 86 study-room project.

HDB interior design — FAQs

What does HDB interior design include?

For most HDB flats it covers space planning and layout, carpentry and built-ins (wardrobes, kitchen cabinets, feature walls), wet works and waterproofing, electrical and lighting, and finishes such as painting, flooring and false ceilings. In short — the design of how the flat looks and works, plus the renovation that builds it.

What's the difference between an interior designer and a renovation contractor?

An interior designer focuses on the look, layout and material choices; a renovation contractor carries out the physical work. We're a direct renovation contractor with an in-house team, so the design intent and the build are handled together — you deal with the people doing the work, with no middleman markup on labour.

What is turnkey interior design?

Turnkey means one team takes your flat from empty (or dated) to move-in ready — design, carpentry, tiling, electrical, plumbing, painting and finishing under one coordinated scope and one itemised quotation, so you're not managing separate trades yourself.

How much does HDB interior design cost in Singapore?

As an indicative market guide, HDB renovations run from about $36k for a smaller BTO to roughly $80k–$97k for a larger or extensively renovated resale flat; a typical 4-room BTO sits around $51k–$62k and a 4-room resale around $64k–$80k. These are planning ranges, not a quote — we itemise your exact scope after a free site visit. See our HDB renovation cost guide or try the renovation calculator.

How long does an HDB renovation take?

A typical HDB renovation runs about 6–10 weeks for a BTO and 8–14 weeks for a resale flat, depending on scope and how much hacking, rewiring and re-piping is involved. Smaller, partial renovations are quicker; you get a schedule alongside your quotation.

Do I need an HDB-registered contractor and permits?

Certain works — hacking, plumbing and electrical changes — must be carried out by an HDB-registered renovation contractor and may need a permit. We advise what your specific flat needs and work within HDB's renovation guidelines.

BTO or resale — which needs more work?

A BTO starts bare and new, so spend goes mostly on carpentry and finishes. A resale flat is lived-in, so it often needs hacking, rewiring or re-piping on top of the finishes — which is why resale ranges tend to be higher.

Do you design condominiums and commercial spaces too?

Yes. Alongside HDB flats we handle condominium interiors and commercial and healthcare spaces such as offices, retail and clinics — the same in-house team, end to end.
