Where the money goes
In most renovations, carpentry takes the biggest share, followed by wet works and tiling, then flooring, electrical, painting and finishing, with hacking, disposal and permits on top. Directing the budget to what counts — carpentry hardware, waterproofing — and economising on low‑impact finishes is how you stay on budget.
What pushes cost up or down
- New vs resale — resale needs hacking and often renewed waterproofing and wiring. See BTO vs resale.
- Scope — whole‑home vs selected rooms.
- Finishes — the quality tier you choose.
- Hidden surprises — more likely in older flats.
