Factors that affect the cost of a home renovation in Singapore

While the average renovation cost for new BTO flats is between $34,000 and $70,000, what you might end up paying for your home makeover could end being more (or less) depending on the following factors:

Property-related renovation cost factors

  • The type of home you have

Surprisingly, renovating a condominium unit could be less expensive than an HDB flat. This can be attributed to the fact that condominium apartments in Singapore often come ready with storage fixtures and flooring, which means saving on carpentry and tiling costs.

  • The age of your HDB flat

No surprises here, the older your HDB flat, the more expensive it's going to be to renovate. The difference in renovation cost between a brand-new BTO flat and a resale HDB flat can be as low as $2,000 to as high as $14,000

  • The size of your HDB flat

The bigger your HDB flat, the higher its renovation cost. For instance, the difference in cost between renovating a new 3-room BTO flat and a new 5-room BTO flatcan be as much as $8,000

Work-related renovation cost factors

The bulk of costs for an HDB flat renovation tends to come from:

  • Hacking: $400 – $700

Demolishing and/or re-building walls or structures within a house.

  • Masonry: $1,300 – $3,000

Laying of tiles and flooring foundations as well as post-hacking touch up.

  • Carpentry: $3,400 – $6,100

Construction of home fixtures like shelves, box-ups, and cabinets.

Other renovation works that add to the bill include:

  • Electrical works: $1,700 – $3,200

Installation of electrical outlets, lighting, and heater power points.

  • Painting: $200 – $1,400

Painting 2 to 3 coats of paint to walls and ceilings.

  • Windows, doors, and grilles: $2,600 – $5,100

Installation of fixtures like glass panes, aluminium window grilles, and wooden doors.

  • Cleaning and disposal: $300 – $1,100

Includes post-renovation clean up works, including acid/chemical washes, haulage, and debris disposal.
