HDB Renovation Guide Singapore: Open-Concept Living Rooms

Our HDB Renovation Guide Singapore breaks down how to open up your living room in 2025 without touching structural walls. The takeaway: knock only non-structural partitions with a permit, zone with furniture and rugs instead of walls, and keep clear walkways. Open plans work in 4-room and 5-room flats far better than in tight 3-room ones.

knocking non-structural walls needs a permit

To get an open plan you often hack a non-structural wall between the kitchen and living room. That work needs a HDB renovation permit, and it must be done by a contractor in HDB's Directory of Renovation Contractors. Using anyone else can cost up to S$5,000 in fines.

Permit approval takes up to 3 weeks, or 3 to 7 days for simple cases, and a BTO permit lasts 3 months. In my experience book the hack the moment you get keys, because the clock starts then. A HDB-approved contractor files the plan and you wait.

Never touch RC ledges, beams or columns. Those are structural and hacking them carries a S$5,000 fine plus forced reinstatement. If you are unsure which wall is safe, your contractor should check the floor plan with HDB before cutting.

Think about the resale clock too. Permits for a resale flat last only 1 month, so the hack must happen fast once approved, while a BTO permit gives you 3 months. Either way, noisy works stay in the 9am to 5pm weekday window, with no work on Sundays or public holidays, or the fine hits S$1,000. A contractor on the DRC list knows these hours and files the plan for you.

HDB Renovation Guide Singapore: zone the space without walls

Once the wall is gone, you still need the room to read as separate areas. Rugs do this fast. A 2m by 3m rug under the sofa marks the living zone, while the dining set sits on bare tile. This costs far less than building a half wall.

Carpentry helps too. A low console or open shelf at the kitchen edge hints at a boundary without blocking light. I've seen this work better than glass panels, which collect grease in Singapore kitchens. Keep the line of sight open and the flat feels bigger.

• rug to anchor the sofa zone
• low carpentry as a soft divider
• pendant light over the dining table

keep the traffic flow clean

Open rooms fail when paths cross. Leave at least 90cm between the sofa and the TV console, and keep the walk from the door to the kitchen clear. In a 4-room flat that usually means the dining sits between the two, not blocking the run.

Plan this on paper before you buy furniture. I've watched homeowners cram a 3-seater, a 2-seater and a 8-seater table into a 4-room and lose all flow. Your HDB BTO renovation budget stretches further when the layout is right first.

Open up only what is legal, mark zones with rugs and low carpentry, and protect the walkways, and your flat feels twice the size. Stay inside HDB rules and the permit process is just a few weeks of waiting, not a fight.

This HDB Renovation Guide Singapore approach keeps the spend where it shows. Carpentry and cabinets take about 40% of a 4-room BTO budget of S$30k to S$66k, so a low divider and a good rug cost little next to that.
