HDB Interior Design Singapore: Plan a 3-Room Flat

HDB interior design Singapore for a 3-room flat is a study in discipline because the home spans only about 60 to 65 square metres including the bomb shelter and service yard, leaving roughly 45 square metres of true living space. Recent resale demand has pushed many couples and empty-nesters into 3-room flats, and HDB's noise rules mean you plan the work around weekdays 9am to 6pm only. This article walks through a full plan you can hand to a contractor.

HDB interior design and the renovation permit

Before any hammer lifts, your contractor must submit a renovation permit to HDB. Only HDB Licensed Renovation Contractors on the Directory of Renovation Contractors may file it, and processing takes about 2 weeks. The permit lists the exact works: hacking, tiling, carpentry, plumbing. Submit it early so your BTO renovation timeline does not slip.

Follow this sequence to keep the permit clean:

1. Engage an LRC and agree the scope in writing, with a floor plan marked for hacking.
2. The contractor files the permit through HDB's system with drawings and the contractor's licence number.
3. Wait for approval, about 2 weeks, before delivering materials to the flat.
4. Display the approved permit at the renovation site as HDB requires.
5. Keep noisy works inside weekdays 9am to 6pm. No hacking or drilling on Sundays and public holidays.

Skipping the permit risks a stop-work order and fines. The 2 week buffer also protects your moving date.

Map the rooms against the real footprint

A 3-room flat has two bedrooms, one bathroom, a kitchen, a living and dining zone, plus the bomb shelter and service yard. The bomb shelter cannot be renovated. You may add only light fittings and laminated flooring inside, and the door must stay as HDB supplied it. Treat it as a storeroom, not a living space.

Plan the main bedroom for the couple. The second bedroom becomes a study now and a child's room later, or a guest room with a Murphy bed. The living and dining share one rectangle, so furniture must pull double duty. In a 60 square metre home, the dining table often doubles as the work desk.

HDB flat space saving that actually works

Space saving in a 3-room flat comes from carpentry that hugs the walls. HDB approved materials like laminate and lightweight panels suit custom builds, and the results beat loose furniture.

• Platform bed with storage underneath. Lift the mattress 40 centimetres and you gain a full-height drawer bank equal to a small wardrobe.
• Built-in wardrobe to the ceiling. Use the top 30 centimetres for seldom-used luggage.
• Cantilever table at the window. A wall-fixed slab seats two without legs stealing floor space.




• Pull-out pantry in the kitchen. Narrow 15 centimetre towers hold spices and oils in dead gaps.
• Study nook in the second bedroom. A 60 centimetre deep counter with wall shelves turns a corner into an office.

Pair these with HDB approved flooring such as vinyl or laminate. Vinyl clicks over the existing substrate, needs no hacking, and survives Singapore's humidity better than solid timber.

Kitchen and the open concept question

HDB allows open concept kitchens, and newer BTO kitchens arrive induction-ready. If you want an open layout, remove the non-structural partition between kitchen and living, but keep the structural beam untouched. Gas appliances follow SP Group and SCDF rules, so an induction hob is the simpler path for most 3-room owners.

Build the kitchen in this order:

1. Fix the wet areas first. HDB BTO already tiles the bathroom and kitchen floor, so decide early if you keep or hack them.
2. Run the plumbing and electrical points before carpentry arrives.
3. Install base cabinets and the quartz or solid-surface countertop.
4. Add the overhead units and a pull-out pantry last so the floor stays clear for tiling touch-ups.

A tight 3-room kitchen rewards drawers over doors. Deep drawers hold pots better than a single shelf behind a hinged door.

Lighting, windows, and child safety

HDB requires window grilles on windows for flats above certain floors for child safety, and removal is regulated. Keep the grilles or apply for approval before changing them. Inside, layer light with a ceiling LED, task lights at the study nook, and warm strips under the carpentry. Cool white in the kitchen, warm white in the bedroom.

Use the service yard for the washer and a retractable drying rack. A 3-room flat has no balcony to spare, so the yard does the heavy lifting for laundry.

A 3-room flat rewards owners who plan the whole home as one system rather than room by room. Whole-house customization maps the carpentry, flooring, and lighting to your exact 60 square metres so the platform bed, study nook, and open kitchen add up instead of fighting for space. Bring your floor plan to a designer who files the HDB renovation permit for you, and ask for a single quotation that covers carpentry, vinyl flooring, and lighting before you collect keys.
