HDB Renovation Guide Singapore: Executive Flat Layouts
An Executive flat is the largest standard HDB type, around 130 square metres with a separate dining area most flats lack. This HDB Renovation Guide Singapore explains the layout, the carpentry scale it demands, and how to zone living spaces in 2025 and 2026.
What sets an executive flat apart
Executive flats run bigger than a 5-room. You get four or five rooms plus a distinct dining space not part of the living room.
The footprint means more walls to decide on, more floors to tile, and far more cabinetry than a standard flat needs.
About 80% of Singapore lives in HDB flats, but executive units are a smaller share. Treat the space as a rare asset.
Layout reading before you hack
Map the structural walls first. You may hack non-structural partitions with an HDB permit, but beams, columns, and RC ledges stay.
Moving the toilet or kitchen is prohibited. Keep wet areas where HDB placed them.
I like to walk the empty flat and mark where light falls at 10am and 4pm. That tells more than any floor plan.
HDB Renovation Guide Singapore carpentry at scale
Carpentry is close to 40% of budget, and on an executive that is a lot of metres of cabinetry.
- Kitchen run is longer, often with a peninsula or quartz island for prep and casual meals.
- Wardrobes multiply across more bedrooms, each worth running to ceiling height.
- Display and storage walls in the living area hide clutter without closing the room.
- Study or craft zone built into a recess saves a whole spare room.
Order early. Fabrication for this volume takes three to four weeks before install starts.
Zoning the living areas
Split living and dining with a low feature wall or a change in flooring, not a full partition. You keep sightlines but gain definition.
Use the dining zone for a proper table, not a fold-out. Executive flats earn that luxury.
For the home worker, carve a quiet corner near a bedroom, away from the TV wall.
Permits and who does the work
Your contractor must be in the HDB Directory of Renovation Contractors under the Renovation Control Rules 2006.
Door repositioning, toilet tile changes, and window swaps need permits or approved trades. Rewiring needs a Licensed Electrical Worker; plumbing a PUB-licensed plumber.
Structural changes need a Professional Engineer from the PEB. Most executive renos do not, but confirm before you assume.
Budget and timeline notes
Resale executive flats cost 20% to 40% more than BTO for the same work, with tear-out driving the gap.
A full reno lands in the 12 to 16 week band for resale, shorter at 8 to 12 weeks for BTO. Permits stay valid 3 months for BTO, 1 month for resale.
Keep 10 to 15% contingency. The larger the flat, the more small add-ons add up.
An executive flat rewards owners who zone first and decorate last. Decide how you live in the space, then let carpentry follow.
