Real cost ranges for Singapore, priced in SGD. Every row is what homeowners actually spend across the scope spectrum — the low end is a pull-and-replace on the existing footprint, the high end is a full custom build with premium finishes.

Cabinets, counters, appliances, and plumbing/electrical updates drive the range. The top of the band reflects full layout changes and premium finishes; the bottom holds for pull-and-replace scopes on the existing footprint.
Scope yours with Baily in SingaporeTile, fixtures, and waterproofing are the big drivers. Primary and ensuite bathrooms with walk-in showers or freestanding tubs sit near the top of the band; hall baths come in closer to the bottom.

Scope yours with Baily in SingaporeAsk Baily about your Singapore renovation and you will not be passed around. Singapore is our first Asia-Pacific market because the local renovation economy is highly regulated, tightly zoned between HDB flats, private condominiums and landed property, and populated by aggregator platforms like Qanvast and HomeRenoGuru that route each homeowner enquiry to a dozen interior-design firms at once. Baily does it differently. We introduce one Singapore contractor registered under the Building and Construction Authority Contractors Registration System with the appropriate workhead grade for your flat, condo or landed home. That contractor understands the HDB upgrading restrictions if you are in public housing, the Management Corporation Strata Title approval workflow if you are in a condominium, and the URA planning-permission pathway if you own landed property. One pro per homeowner from first message through defects liability. No quote-farming, no chasing interior-design firms who vanish mid-project. The contractor we introduce is the contractor who finishes the job and hands back the HDB permit card or condo acknowledgement.
