Not about permits — about making a fixed, modest footprint feel generous. Every wasted centimetre is visible.
An HDB flat rewards planning more than decoration, because there is no spare space to absorb a bad decision.
Storage is a planning problem before it is a carpentry problem
The useful question is never 'how many cabinets?' but 'what has no home?' — the vacuum, the ironing board, the suitcases, the festive decorations, the stroller. Standard furniture wastes HDB dimensions: a 600mm-deep wardrobe in a 700mm recess leaves a gap that collects dust and holds nothing, and stops at a convenient height leaving the top metre of wall unused. Custom carpentry takes the full depth, runs to the ceiling, and works around the things that cannot move — bomb shelter door, beams, pipe ducts, aircon trunking — turning obstacles into storage.
Light and colour do more for perceived space than layout changes
Before hacking anything, it is worth exhausting the cheaper moves. Light colours reflect light and make a room read larger; cooler tones read calmer and more spacious, which is why they suit small bathrooms. A ceiling lighter than the walls feels higher. Singapore daylight is bright and slightly cool, so a colour chosen under showroom lighting often reads differently at home — always test a sample on your own wall and look at it morning and evening. Layered lighting, rather than one central fitting, is what stops a compact room feeling like a corridor at night.
Designing for how the household actually lives
Whether the home needs to be safe for a toddler or easy for a grandparent changes real decisions, not just finishes. Rounded carpentry corners, soft-close hardware, slip-resistant flooring in wet areas and washable paint matter with young children. Grab bars, level thresholds, lever handles, storage between hip and shoulder height and considerably more light matter with older residents — and HDB's Enhancement for Active Seniors scheme subsidises grab bars, ramps and slip-resistant treatment of existing tiles for eligible households, at up to 95% of the cost, so it is worth asking about before paying privately.
Where the design meets the rules
Design intent still has to survive the permit. Walls may be structural, wet areas have waterproofing and floor-level consequences, and window replacement needs approval. We would rather tell you at concept stage that something is not permissible than draw it beautifully and have it fail later. If your project involves hacking, rewiring or wet-area changes, the BTO and resale guides set out the approval route in detail.
Approvals & rules
Who approves the work.
Approving bodyHDB
Structural walls cannot be removed; in a flat, assume a wall is structural until confirmed otherwise.
Hacking, wet-area alterations, rewiring and window replacement require HDB approval.
The renovation permit is applied for by an HDB-registered renovation contractor.
The Enhancement for Active Seniors (EASE) scheme subsidises elderly-friendly fittings for eligible households, up to 95% of cost.
Rules and timeframes change. These were checked against the linked official pages on the date shown — please confirm anything critical with the relevant authority.
What drives the cost
Where the money actually goes.
Listed roughly largest first, for this property type specifically. A reliable figure still needs a site assessment — this is what to expect it to be made of.
We do not quote a fixed package price, because two homes of the same size rarely need the same works.
01
Quantity and specification of built-in carpentry, by a wide margin
02
Whether the layout changes, since hacking pulls in permits, wet works and finishes
03
Lighting and electrical point count
04
Finish level — the same cabinet in two door materials is a materially different price
05
Accessibility or child-safety provisions, though EASE may offset some of these
Common mistakes on this property type
Designing around images rather than around what currently frustrates you
Choosing colours under showroom lighting and never testing them at home
Matt paint in a home with young children
High-gloss tiles in wet areas or anywhere children run
Filling every wall with carpentry — a small flat needs breathing room more than it needs cabinets
How long it takes
Timeline, honestly.
Design and selections typically run 4 to 8 weeks before site works begin. Bringing a floor plan early is what shortens this.
Delays most often come from late material selections or changes requested mid-build, not from the site work itself.
Questions worth asking
What we'll ask you first.
01
What frustrates you most about how your current home works?
02
What specifically has nowhere to live at the moment?
03
Who lives here, and is that likely to change?
04
Are there young children or elderly family members to design for?
05
Which rooms do you actually spend your evenings in?
Not sure of the answers yet? That is fine — working them out is part of the first conversation. For the wider picture, the renovation guide covers permits, hours, materials and costs in detail.
