If you live in a 3-room HDB flat in Singapore, you’re probably familiar with the challenges of designing a home that balances style, comfort, and function, all within a limited space. Whether it’s a BTO or resale unit, a well-planned renovation can dramatically transform your apartment into a modern, efficient, and beautiful living space.
In this guide, we’ll explore everything you need to know about 3 room HDB renovation, including design ideas, layout tips, budget considerations, and how to make small spaces work for you.
What Is a 3-Room HDB Flat?
A 3-room HDB flat typically ranges from 60 to 70 sqm, with two bedrooms, a living area, a kitchen, and one or two bathrooms. It’s a common choice among young couples, singles, and small families in Singapore.
Despite the compact size, a 3-room flat offers plenty of opportunities for creative and intelligent interior design.
Common Renovation Challenges for 3-Room HDB Flats
1. Limited Space
Maximising every inch is crucial. Without proper planning, a small flat can quickly feel cluttered or cramped.
2. Older Layouts in Resale Flats
Many older 3-room units have outdated floor plans or finishes that need modernising.
3. Storage Constraints
With fewer built-in cabinets or awkward corners, storage must be customised without compromising aesthetics.
3 Room HDB Renovation Ideas That Work
✅ Open-Concept Layouts
Breaking down non-structural walls (with HDB approval) between the kitchen and living room can create an airy, spacious feel. This also encourages better light flow and social interaction.
✅ Built-In Carpentry
Custom-built wardrobes, platform beds with storage, and built-in study desks can maximise vertical and underused areas. Use carpentry that blends into the wall colour to reduce visual clutter.
✅ Neutral and Light Colours
Whites, greys, and pastels help reflect light, making your rooms feel more open. Consider two-tone palettes to add subtle depth without overwhelming the space.
✅ Sliding Doors
Replace hinged doors with sliding or pocket doors to save space and add a modern touch, especially for bathrooms, wardrobes, and kitchen entryways.
✅ Compact Appliances and Fixtures
Opt for slim-profile washing machines, compact sinks, and multi-functional kitchen appliances to keep things functional yet space-efficient.
Popular Interior Design Styles for 3-Room HDB Flats
1. Farmhouse
The Farmhouse renovation style blends rustic charm with modern comfort. It typically features natural materials like wood and stone, exposed beams, neutral tones, vintage accents, and practical layouts.
Modern farmhouse updates often include open-plan kitchens, shiplap walls, black metal fixtures, and barn-style doors, creating a cozy, timeless feel that balances old-world warmth with contemporary functionality.
2. Japandi
A fusion of Japanese and Scandinavian design styles, combining the minimalism and natural elegance of Japan with the warmth and functionality of Scandinavian interiors.
It features clean lines, muted colour palettes, natural materials like wood and linen, and clutter-free spaces that emphasise calm, balance, and intentional living.
3. Modern Industrial
Modern industrial interior design blends raw, unfinished elements with sleek, contemporary touches. It often features exposed brick walls, concrete or metal surfaces, open layouts, and neutral tones like grey, black, and white.
The style highlights structural elements such as pipes and beams, while incorporating minimalist furniture and moody lighting to create an edgy yet sophisticated urban aesthetic.
Contemporary minimalist design is defined by clean lines, open spaces, and a restrained colour palette. It focuses on functionality, simplicity, and intentional use of materials, often combining neutral tones, natural textures, and sleek, modern furnishings.
This style avoids clutter, favouring quality over quantity, and creates a calming, spacious environment that feels both elegant and efficient.
