Design Ideas for 2, 3, 4 and 5-Room BTO Flats at Costa Grove

The wait is almost over!

Costa Grove is set to TOP in Q2 2026, and if you’re one of the lucky homeowners who secured a unit, the countdown has officially begun!

As key collection approaches, it’s the perfect time to start curating your renovation mood boards or reaching out to interior designers for quotations. You might also want to play around with different layout ideas using our latest BTO space planning tool, in collaboration with Wizlah.

Not sure where to begin? We’ve got you covered. Here are some design inspirations tailored to Costa Grove’s flat layouts to help you kick-start your planning.

Costa Grove 2-Room Flexi BTO flat design ideas

There are two layout variations for the 2-room flexi BTO flats at Costa Grove. Notable differences include:

• A larger kitchen, household shelter, living/dining area, and bedroom for Type 2
• A longer entryway for Type 1

That said, both layouts share a similar overall configuration — so the design ideas below can be applied to either one with minimal adjustments.

Here are some ways you can design the space:

a) Go for a Japanese-inspired open suite…

If you love a minimalist look inspired by Japanese interiors, take cues from this home with light wood tones and a clean, airy layout.

The shoji-style sliding windows in the living room bring in soft, diffused light and add that unmistakable Japanese touch without overwhelming the space.

Paired with an open suite layout, the whole home feels breezy and serene — perfect if you want a compact space to feel warm, calming, and effortlessly Zen.

b) ...or partition and conceal the bedroom entrance for privacy

If you host occasionally and a fully open suite feels a little too exposed, partition the bedroom. In this home, the concealed bedroom entrance offers privacy where it matters, while still keeping the overall layout feeling spacious and connected.

The built-in bench at the dining area also helps maximise the use of a small footprint — offering comfortable seating and extra storage (under the seats) without cluttering the walkway.

It’s a practical setup that balances openness with privacy, and shows how small tweaks can shape how the entire home feels.

Costa Grove 3-Room BTO flat design ideas

a) Make use of space-maximising furniture

The living and dining area of the 3-room layout is rather tight and squarish, so every piece of furniture has to work a little harder. Here, a custom banquette along the side of the household shelter creates a cosy, space-saving dining nook without eating into the walkway.

Paired with a movable island—which also doubles as storage thanks to the cabinets below—you get a flexible dining setup that can shift between meals, prep work, or even WFH.

In the bedrooms, the use of Murphy beds offers the same kind of versatility.

When folded up, it frees up valuable floor space; when down, it functions just like a regular bed, keeping a compact room adaptable without compromising comfort.

b) Integrate your dining table with the kitchen peninsula

If you prefer a more streamlined layout, consider flushing your dining table and have it extend out from a kitchen peninsula. You can also install power points around the peninsula for appliances or those steamboat nights.

This instantly turns the suggested dry-kitchen area into your main dining zone, freeing up precious space in the living area for a bigger sofa, more storage, or simply better flow.

Costa Grove 4-Room BTO flat design ideas

a) Open up the spare room for an expanded living/dining space

If you love hosting or simply want a roomier living area, consider hacking the spare bedroom beside the living room. Removing that wall instantly widens the layout, giving you far more flexibility in how you use the space.

Here, the enlarged zone easily accommodates an 8-seater dining setup and a generous sofa distance. It’s a simple layout change with a big payoff, especially for families who prioritise communal space.

With the dining area shifted to the new space next to the living room, the entrance to the open-concept kitchen also feels less constricted, making the overall flow smoother.

b) Create a dumbbell layout by switching the living room and common bedroom’s positions

Some homeowners prefer a more linear flow from the living room to the dining and kitchen. One way to achieve this is by swapping the living room with one of the common bedrooms to form a dumbbell layout.

In this home, the layout change creates a cosy living area, while the newly carved-out room sits behind a see-through panel fitted with blinds on the inside. This keeps the space visually light while still allowing the homeowners to control privacy when needed.

To make the most of the layout, a structural pillar was cleverly integrated into a pantry setup, and strategically placed mirrors help visually widen the room for a brighter, more open feel.

Costa Grove 5-Room BTO flat design ideas

a) Think about framing the waterfront view

If you were lucky enough to snag a stack facing Pasir Ris Park and the sea, it’s worth thinking about how your layout can frame that view — especially in the living and dining area.

By keeping the space clean and uninterrupted, the panorama outside naturally becomes the focal point of the home.

And once you let the view lead the design, everything shifts — the space feels brighter, more open, and effortlessly elegant.

b) Have the pantry double as a partition for the study

Instead of using a see-through divider for the suggested study area (like many 5-room flats do), this home takes a different approach: the partition wall is turned into a full-fledged pantry.

By building storage and countertop space on the outer side of the study, the partition now pulls double duty — it keeps the workspace private and adds a practical pantry zone right beside the kitchen.

The same design mindset carries through to the bedroom. Rather than fighting the bulk of the structural beam, the wardrobes are built flush around it, creating a clean, seamless facade that keeps visual clutter low.

With storage fully integrated and the circulation kept unobstructed, the room feels calm, cohesive, and just as functional as the rest of the home.

c) Build an enclosed play area for your furbabies

If you’re designing a pet-friendly home, consider dedicating a safe, enclosed space for your furbabies to roam, climb, and play.

In this home, the owners built a cat enclosure right next to the study, integrating it into the home’s design without compromising on the overall aesthetics.

It’s a practical way to give your pets their own space while keeping the rest of the home neat and intentional.

Because in every home, there should always be a corner reserved for chaos… contained chaos.
