3-Room BTO Renovation in Singapore (2025 Guide with Case Studies)

Why 3-Room BTO Renovation Is Different

A 3-room BTO flat is compact — averaging about 65 sqm — but with clever carpentry and design, it can feel spacious and functional.

In 2025, homeowners are spending anywhere from S$30,000 to S$90,000 to turn these smaller units into dream homes.

Unlike 4- or 5-room flats, every square foot counts. That means smart carpentry, multi-purpose furniture, and efficient layouts are key.
