Trending 5-Room HDB Interior Design and Renovation Ideas in Singapore in 2025
HDB apartments are the most popular form of housing units in the Singapore market. These types of apartments come in a wide range of sizes and layouts. While 3-room HDB and 4-room HDB units are the most common and affordable ones on the market, 5-room HDB units offer the best living conditions and space that you can get in flat living.
A typical 5-room BTO floor plan usually offers around 110 square meters of space, which is enough even for families of 5 or more members to have more comfortable indoor space. While such a large space may offer each member a space of their own, it also offers a blank canvas for homeowners and designers to work their magic in interior design.
Here, we discuss some trending 5-room HDB living room design ideas, along with affordable 5-room HDB interior design tips and practical, inspirational ideas.
Singapore 5-Room HDB Interior Design Ideas in 2025
Elevate your 5-room HDB with these four trending interior design styles for 2025, tailored to Singapore’s humid climate and large family needs.
Modern Luxe: Glamour Meets Comfort
A 5-room HDB calls for luxury and elegance that can further enhance its ambience. Modern luxe combines sophistication with approachability through plush textures (velvet, leather), marble accents, and gold or brass details. You can add luxurious details with statement chandeliers and mirrored panels for an even more glamorous touch. Matte laminates for cabinets in the kitchen can help resist Singapore’s humidity.
Wabi-Sabi: Beauty in Imperfection
Wabi-sabi, a Japanese aesthetic concept, embraces natural materials (wood, linen), organic shapes, and neutral tones (beige, taupe) to create a simple yet tranquil atmosphere. Textured walls and aged brass add warmth to 5-room HDBs. A wabi-sabi dining area with a reclaimed wood table and linen curtains can foster serenity and calm. Incorporate potted plants to enhance the natural vibe; ideal for Singapore’s urban setting.
Biophilic Design: Nature-Inspired Retreat
Biophilic design is a trending interior design style in Singapore that can connect your 5-room HDB to nature through indoor greenery, bamboo finishes, and earthy colours (sage green, terracotta). Large windows maximise natural light while sheer curtains can help maintain the same bright ambience in the space.
Smart Home Integration for Modern Living
With technological advancements in all areas of life, it is no surprise that you see smart integration and features in interior design in recent times as well. In 2025, smart homes that utilise AI, voice commands, and smartphone-controlled features are trending. Whichever interior design style you choose for your 5-room HDB, by integrating your furniture and lighting with smartphone and voice commands, you can enhance convenience and space efficiency in your home.
Room-By-Room Inspirational 5-Room HDB Interior Design Ideas
Below, we discuss some amazing ways in which you can design each room of your 5-room HDB.
5-Room HDB Living Room Design

The most popular interior design trend right now is combining the living room with the kitchen area through an open-concept layout. Since these areas are most often used throughout the day, it is a great idea to combine them so the conversation doesn’t stop.
5-Room HDB Kitchen Design
For the kitchen, you can choose any colour of your choice for the kitchen cabinets and countertops. If you wish to go with a light colour like white or beige, you may be able to create an aesthetically pleasing ambience; however, such a light-coloured kitchen will require much more cleaning and maintenance to maintain its appearance. Therefore, the best 5-room HDB colour scheme for a kitchen is some dark hue that will make the kitchen not only easy to clean but also appear stunningly beautiful. For example, in the following kitchen design portfolio, the black kitchen cabinets create the perfect contrast with the white countertops and white marble floor.
5-Room HDB Master Bedroom Design
For the perfect bedroom, you must ensure that it is designed for comfort and sleep. So, the colours and the kind of furniture you put into the room are very important for a healthy area that will support your sleep.
Light in the bedroom should be ambient light with warm colours so it promotes relaxation and comfort rather than being alert. When we talk about colours in this room, they should be warm, darker tones, or if you like lighter colours, go for pastel complementary tones that promote calmness and leisure.
5-Room HDB Bathroom Design
When we think about 5-room HDB bathroom interior design, most often, we will think about stereotypical white tile bathrooms. But who says that you need to follow this norm? Play around with different styles of tiles and different colours, and we believe that you will achieve some rather interesting results. For example, consider the image above where the designers have chosen sage green shades for an accent wall in the bathroom to give it a unique twist.
5-Room BTO Study Room Design/Office
Depending on the type of job that you do in the office, the interior of this space should reflect your job, and the colours and furniture should promote alertness, concentration in the work, and a pragmatic atmosphere needed to finish the job appropriately. All these elements will help create a productive environment in your study.
5-Room HDB Kids’ Room Design
Since kids crave time to play and explore by themselves, their rooms can be organised in creative ways that are not possible in other rooms in the house. Depending on the age of the kid, you can play with colours in any way and shape you want while still letting them express themselves creatively, as only a child’s creativity can.
By fitting a working table with a computer and bookshelf, they can have a part of the room where they can use the computer just like their parents and free floor space so they can play with toys.
In the picture above, you can see the clever way that a storage room can be made by building the bed above the storage so toys and other things can be stored in a way that won’t steal much of the room’s free space.
Space-Optimising And Practical Solutions for 5-Room HDBs
With 110 sqm, 5-room HDB flats offer flexibility, but having a smart design maximises functionality. Below are some practical and space-optimising tips to create the perfect 5-room HDB.
- Open-Concept Layouts: Merge living, dining, and kitchen areas for a seamless flow. Use glass panels to maintain privacy while enhancing light.
- Dual Kitchen Design: Create wet and dry kitchens for heavy and light cooking. Create a wet kitchen with a robust exhaust system and a dry kitchen island for casual dining.
- Multi-Functional Furniture: Use foldable dining tables or platform beds with storage. You may include a motorised Murphy bed to free up extra space in a bedroom.
- Full-Height Storage: Install floor-to-ceiling cabinets or recessed wardrobes. Include a walk-in wardrobe behind a sliding mirror door.
- Double Dining Spaces: Design a formal dining area for gatherings and a casual nook for daily meals. Use pendant lights to define each space.
HDB Renovation Guidelines
Renovating a 5-room HDB requires compliance with Housing & Development Board (HDB) guidelines to ensure safety and legality. The HDB guidelines in Singapore that must be complied with include:
- Wall Hacking: Non-load-bearing walls can be removed with permits; load-bearing walls are restricted.
- Electrical and Plumbing: Any electrical or plumbing upgrades must meet HDB safety standards.
- Ceilings and Doors: False ceilings must maintain 2.4m clearance (except bathrooms) and use non-combustible materials. Main doors need fire-rated approvals before they can be changed.
- Permit Timeline: Applications for HDB permits take 7–14 days, so you have to plan accordingly.
