Why 5-Room BTOs Are Unique
At around 110 square metres, a 5-room BTO flat offers something most HDB layouts don’t: room to breathe, grow, and personalize. Compared to smaller units, you are working with a larger living area, three full bedrooms, a dining zone, a service yard, and typically more wall space and natural light. But that does not mean every square foot is being used smartly by default; it all comes down to intentional design.
More Room, More Possibilities
What sets the 5-room BTO design apart is its flexibility. That extra bedroom? It doesn’t have to be a traditional guest room; it could be a dedicated home office, kids’ playroom, studio, or even a multi-generational suite.
Larger living rooms make it easier to integrate open-concept layouts, custom-built entertainment hubs, or even split-zoned lounges for different family activities.
Layouts That Reflect Your Lifestyle
Most homeowners don’t just want “more space”; they want spaces that work. That is why 5-room BTO interior design ideas often prioritize the following:
Open living areas that connect the kitchen, dining, and lounge seamlessly.
Private nooks for studying, working from home, or quiet downtime.
Luxury upgrades like walk-in wardrobes, spa-style bathrooms, and mood lighting.
Smart storage that hides clutter while keeping everything accessible.
Design themes that feel cohesive and curated, not only “fitted in.”
Put simply, a 5-room flat gives you a blank canvas to create a home that mirrors your lifestyle now and adapts as it evolves. Whether you are planning for a growing family or designing your forever space, the layout options are virtually endless when done right.
Signature Interior Design Ideas for 5-Room BTO Flats
Designing a 5-room BTO flat is not about filling space but also about using it to enhance your lifestyle. With more square footage comes more freedom, and here is how to turn that into smart, livable design.
1. Grand Open-Concept Living & Dining

Tear down non-structural walls to create one fluid zone for living, dining, and entertaining. A feature wall, built-in console, or statement couch anchors the space while keeping it airy. It is the heart of the home, and with a 5-room layout, you can actually pull it off.
2. Dual-Purpose Rooms

That third bedroom? Make it work harder. Turn it into a study by day and guest room by night, or a kids’ playroom with future adaptability. For multi-generational families, design it with accessible storage and flexible furniture.
3. Luxury 5-Room BTO Design Kitchen Concepts

A 5-room BTO kitchen can accommodate island counters, breakfast nooks, and even separated dry and wet zones. Use quartz surfaces, integrated appliances, and color-pop cabinetry to marry function with flair.
4. Entertainment & Lifestyle Corners

Whether it is a home theatre, wine display, or a gaming nook, use awkward corners or extended living room areas to build lifestyle-centric features.
5. Walk-In Wardrobes or Dressing Areas

Create boutique-style storage in your master bedroom using frosted glass partitions or L-shaped carpentry. Think beyond only storage, think sanctuary.
6. Bathroom Upgrades
Install rain showers, warm cove lighting, and textured tiles for that hotel bathroom feel. With a little planning, even your common bathroom can feel like a spa retreat.
7. Smart Home Integration
From automated blinds to voice-activated lighting, smart home tech blends beautifully with larger layouts. Plan wiring and hubs early to future-proof your home.
Style Inspirations for 5-Room BTOs
Bigger spaces deserve bolder styles, and a 5-room BTO gives you the freedom to lean into statement aesthetics without the usual constraints.
Here are seven interior design themes that make the most of your layout while delivering visual impact, comfort, and personal expression.
1. Urban Chic Loft

Inspired by New York lofts, this style plays with exposed brick, matte black accents, and bold lighting fixtures. The large open-plan spaces of a 5-room flat mimic industrial lofts, giving you room to experiment with high-contrast tones and textured materials.
2. Coastal Breeze
Think light woods, sheer curtains, and a palette of whites and seafoam blues. This laid-back, beachy look makes your home feel like a getaway, ideal for homeowners seeking a refreshing, relaxed vibe.

3. Modern Oriental Elegance
Combine Asian heritage details like lattice screens or warm wood joinery with modern silhouettes and clean lines. It adds a sense of timeless depth, perfect for those who want culture without the clutter.
4. Art Deco Revival
Bring drama to your space with geometric patterns, jewel tones, and metallic accents. The larger layout of a 5-room BTO gives bold Art Deco elements room to shine without overwhelming the space.
5. Green Living (Eco-Modern)

From indoor plant walls to sustainable materials like rattan and reclaimed wood, this look champions eco-conscious living. The ample natural light and airflow in 5-room flats make this style both gorgeous and functional.
6. Contemporary Classic

Merge traditional detailing like wainscoting or crown moulding with modern furnishings for a home that feels refined yet livable. It is an ideal balance for growing families who want a space that is both elegant and enduring.
7. Resort Luxe
Neutral tones, mood lighting, and spa-inspired bathrooms set the tone for this high-end aesthetic. Use materials like stone, teak, and soft textiles to bring a calm, luxurious “staycation” feel to daily life.
Space Planning Strategies for 5-Room BTO Flats
With great space comes great responsibility, and that means smart space planning is essential to avoid that “big but empty” feeling.
A well-designed 5-room BTO layout should balance openness with purpose, making sure every corner supports your lifestyle.
Make Every Corner Count
Don’t let valuable square footage go to waste. Transform underutilised corners into something functional, like a reading nook, a built-in study desk, or even a mini indoor garden.
With thoughtful planning, awkward areas become opportunity zones.
Open Yet Intentional
While open-concept designs are a favourite for 5-room BTO interior design, they work best when you define zones clearly. Use rugs, lighting, or shelving units to subtly divide living, dining, and work areas, without sacrificing flow.
Flexible Partitions
For families with evolving needs, sliding glass doors or folding panels allow you to create privacy when needed (like during Zoom meetings or guest stays) while keeping the layout open and breathable. It’s the perfect way to future-proof your flat.
Done right, space planning is not only about fitting things in but also about designing for how you live today and how you will grow tomorrow.
Renovation Cost Guide for 5-Room BTOs
Designing a 5-room BTO is not only about style. It is also about smart spending, too. With more space to work with, renovation costs can add up quickly. On average, expect to budget SGD $45,000 to $70,000, depending on how extensive your plans are.
What Drives the Cost?
Carpentry: Built-ins like wardrobes, kitchen cabinets, and custom TV consoles are often the biggest ticket items.
Hacking & Reconfiguration: Removing walls for open-concept layouts or changing room functions increases labour costs.
Premium Finishes: Think quartz countertops, branded appliances, imported tiles, or integrated lighting; they elevate your space but also your budget.
How to Budget Wisely
Start by prioritizing function over flash. Invest first in areas you will use daily, like a well-designed kitchen, ample storage, and durable surfaces. Then, allocate any remaining budget toward lifestyle upgrades like walk-in wardrobes or a resort-style bathroom.
If you are aiming for a luxurious look without overspending, consider laminate alternatives, modular systems, or phasing renovations in stages. A good interior designer can also help stretch your dollar without compromising on aesthetics or performance.
