HDB renovation budget: A detailed cost breakdown checklist

The main cost components typically include hacking and demolition, masonry works, flooring, carpentry, plumbing, electrical works, painting, and miscellaneous items like permits and cleaning.

Hacking and demolition costs can range from $500 to $2,000 or more, depending on the extent of demolition required, such as removing walls, flooring, or fixtures.

Carpentry work, including kitchen cabinets, wardrobes, and custom storage solutions, usually accounts for a significant portion of the budget, ranging from $5,000 to $20,000 depending on the materials and complexity.

Consider retaining existing structures where possible, opting for more affordable materials, comparing quotes from multiple contractors, and prioritizing essential renovations over cosmetic upgrades.

Electrical work, including wiring, lighting, and outlet installation, can cost between $1,500 to $5,000, depending on the number of points and complexity of the electrical layout.

Hiring an interior designer can add 10-15% to your overall budget, but they can help with space planning, design concepts, and project management, potentially saving you time and money in the long run by avoiding costly mistakes.

Hidden costs can include permit fees, disposal fees, variations due to unforeseen issues, delays, and post-renovation cleaning. Its wise to set aside a contingency fund of 5-10% of the total budget to cover these unexpected expenses.
