5-Room HDB Interior Design Singapore 2026: Ideas, Layouts & Renovation Costs
🔍 A 5-room HDB interior design and renovation in Singapore costs about $55,000–$90,000 for a BTO flat and $70,000–$120,000 for a resale flat in 2026. With roughly 110 sqm or more, the best 5-room designs use an open living-dining-kitchen core, turn the third bedroom into a flexible study, and plan storage zones by family member. The extra space suits Italian Minimalist, Modern French and Modern Luxury styles. |
A 5-room flat is the biggest standard HDB home most Singapore families will own. More space sounds easy, but it creates its own problem: big rooms can feel empty, disconnected or cluttered with too much furniture.
This guide covers how TDF plans 5-room BTO and resale flats in 2026: layouts, room-by-room ideas, style choices and a realistic budget.

Layout Ideas for a 5-Room HDB
• Open the kitchen to the dining area so the cook is part of family life
• Make the dining table the heart of the home: a 6-seater with a statement pendant
• Turn the third bedroom into a study or family room with a sofa bed for guests
• Create a proper entrance zone: full-height shoe cabinet, bench, and a utility cupboard for the vacuum and stroller
• Give each child a desk and shelf zone in their own room rather than a shared study
Room by Room: What Works
Living Room
A long 5-room living room can take a full-width TV wall with a feature finish. For finishes that work in Singapore’s climate, see our feature wall ideas for Singapore homes. Keep the sofa wall plain so the room has one focal point.
Kitchen and Dining
5-room kitchens usually fit an L-shape or a galley with an island or peninsula. Our guide to HDB kitchen layouts and materials compares the options and costs in detail.
Bedrooms
With four bedrooms counting the study, plan storage by person: each child gets a wardrobe with growth room, and the master bedroom gets a walk-in or headboard-wall wardrobe.
✏️ Jerrold Chia, Interior Designer: The most common mistake in a 5-room flat is filling the space because you can. I would rather design fewer pieces with better proportions: one long, low TV console instead of three cabinets, one big dining table instead of a dining set plus a bar counter. In Italian Minimalist and Modern French homes, empty space is part of the design. |
Best Styles for 5-Room HDB Flats
Style | Why It Works in 5-Room | Watch Out For |
Italian Minimalist | Long clean lines suit larger rooms | Needs precise joinery; budget for quality |
Modern French | Wall mouldings and arches fit taller, wider walls | Can look fussy if overdone |
Modern Luxury | Space for darker tones and statement lighting | Needs good natural light |
Japandi | Calm and easy to maintain for families | Can feel sparse in very large rooms; add texture |

FAQ — 5 Questions & Answers
Q1: How much does a 5-room HDB renovation cost in Singapore in 2026?
A: A 5-room BTO renovation typically costs $55,000–$90,000 and a 5-room resale renovation $70,000–$120,000 in 2026. Resale is higher because of hacking, rewiring and bathroom works. Carpentry and the kitchen together usually make up more than half the budget.
Q2: How big is a 5-room HDB flat?
A: Newer 5-room BTO flats are typically around 110–113 sqm. Many older resale 5-room flats are larger, often 120 sqm or more. Check your exact floor plan, since sizes vary by project and year.
Q3: What is the best layout for a 5-room HDB flat?
A: Most families do best with an open living-dining-kitchen core, the third bedroom as a study or flexible room, and a clear entrance zone with full-height shoe and utility storage. With more space, the risk is too many furniture pieces, so define zones with lighting and rugs rather than more items.
Q4: Which interior design style suits a 5-room HDB?
A: 5-room flats have the floor area for styles that need breathing room, such as Italian Minimalist, Modern French and Modern Luxury. Japandi and warm minimalist schemes also work well for families who want a calm, easy-to-maintain home.
Q5: Should I hack walls in a 5-room HDB?
A: Only non-structural walls can be removed, and you need an HDB permit and an HDB-registered contractor. Popular moves are opening the kitchen or combining a bedroom into the living area or a walk-in wardrobe. Check the wall type before you design around it.
