5-Room BTO Flat Renovations in Singapore: From $35K to $190K

November 4, 2025

A closer look at 5-room HDB flat renovations in Singapore.

It might not be as fun as letting your imagination run wild with design ideas, but budgeting for a renovation is just as important as having a firm vision of what your future home will look like.

Maybe even more important, actually, since what you get can differ greatly depending on what you’ve set aside.

While the average renovation cost for a 5-room BTO flat is between $67,400 to $82,400, you don’t necessarily have to fork out that amount to get a decent-looking home.

Here, we share 8 examples of 5-room BTO flats with different renovation costs and ideas so that you can find the best look at the right price!

To keep costs down, built-ins are limited to the ‘necessary’ ones like the TV console, kitchen cabinets, and wardrobes – all of which provide ample storage space while ensuring the space remains airy.

Completing the overall look is the abundant usage of warm ambient lighting – an often-overlooked feature that amps up the homely vibes even more.

Costing $60,000, this renovation had enough leeway to introduce decorative features – like the balcony’s curved archway and several glass block dividers – to elevate the overall look of the home.

The homeowners were also able to revamp their toilets, overlaying the original floor tiles with ones of their choice and erecting custom dividers between the wet and dry areas.

With all these features, you’re probably wondering how they kept their renovation cost relatively low. This is likely achieved by keeping carpentry works simple (nothing big or extensive) and by choosing not to hack any walls.

6. 5-room BTO flat in Sengkang (Renovation cost: $95,000)

View this project by Ricordo Interior

A dark colour palette and marble surfaces are just some of the features that make this modern luxe 5-room BTO flat stand out.

While a space dominated by cool blacks and greys can easily look overly-clinical, this home balances them out with warm wood tones and curved elements that add a cosy touch.

Additionally, the homeowners likely also focused on making their home well-lit – everything from their bedroom corridor to the ceiling are fitted with LED lights that not only illuminate the space, but also introduce another layer of visual interest.

7. 5-room BTO flat in Tampines GreenSpring (Renovation cost: $120,000)

Curves are back in, and this home has them in spades, in the form of organically shaped bay window seats, arched doorways, and subtly-rounded built-ins.

However, note that these features cost more than your average straight-edged ones, due to the need for additional plastering and craftsmanship. This, coupled with the use of limewash surfaces and large-format floor tiles (both of which require more labour) throughout the space, is probably how the renovation cost was racked up to $120,000.

8. 5-Room BTO Flat at Northshore Edge (Renovation cost: $190,000)

View this project by Authors • Interior & Styling

For this couple who transformed their 5-room BTO flat into a corridor-less cafe-inspired home, their generous budget of $190,000 afforded them extensive layout changes, custom curved features, and tiles imported all the way from Italy!

With just the two of them staying in the home, they decided to merge two bedrooms together and use the corridor to extend the bedrooms, kitchen, and XL master ensuite, creating more spacious rooms you typically wouldn’t get in a regular HDB layout.
