New Home Renovation: A Step-by-Step Guide
Just collected the keys? Here is the order to do things in, so your first renovation runs calm instead of chaotic.
Walking into an empty new home is exciting, but a renovation has a natural sequence — skip a step and you pay for it later. Here is the order I walk my own clients through, from empty unit to move-in ready.
Step 1: Plan before you call a contractor
The biggest mistakes happen before any work starts. Walk the empty unit, measure it, and decide how you actually live — where you cook, work, store things and relax. Only then does a budget make sense.
- Separate needs (wiring, waterproofing, basic built-ins) from wants (feature walls, mood lighting)
- Set a total budget and keep a 10–15% contingency aside
- Collect ideas, but lock your design before quoting — changing it later is where money leaks
- Confirm your move-in date so the timeline is realistic
Step 2: Follow the right sequence of works
Renovation has a natural order. Doing things out of sequence means tearing up finished work. Here is the flow I walk clients through for a typical bare unit.
| Stage | What happens |
|---|---|
| 1. Hacking & demolition | Remove or alter walls (never structural ones without an engineer) |
| 2. Wiring & plumbing | First-fix electrical points and pipe runs before anything is covered |
| 3. Waterproofing | Bathrooms, kitchen yard and any wet area — then a water test |
| 4. Plastering & ceiling | Skim coat, cornices, plaster ceiling and concealed lighting boxes |
| 5. Flooring | Tiles, vinyl or timber once wet works are sealed |
| 6. Carpentry | Kitchen cabinets, wardrobes and built-ins (usually quoted per foot run) |
| 7. Painting & clean-up | Final coats, fittings, deep clean and defect check |
Step 3: Sort approvals and paperwork
In a strata property (condo, serviced apartment, gated community) you cannot just start hacking. There are rules, and ignoring them can mean fines or being told to reinstate.
- Apply for renovation approval from the JMB or MC (management) — expect a deposit and fixed working hours
- Hacking, structural or external changes may need local council approval (e.g. MBJB in JB, DBKL in KL)
- Keep a written contract covering scope, materials, timeline and staged progress payments
Step 4: Get it in writing and pay in stages
Before committing, get at least three written quotes on a like-for-like scope so you can compare fairly. Then protect yourself with how you pay.
- Use a clear contract — scope, materials, brand/grade, timeline and payment schedule
- Avoid paying a large sum upfront; tie payments to completed stages (e.g. a deposit, then milestone payments)
- Hold a small retention at the end until defects are fixed
- Agree how variations (changes) are priced before they happen

Frequently asked questions
How long does a new home renovation take?
For a bare condo unit, a typical fit-out runs around 6 to 12 weeks depending on scope, carpentry volume and approvals. A full landed-house renovation can take longer.
Do I need management approval to renovate a condo?
Yes. Strata units need written renovation approval from the JMB or MC, usually with a deposit, permitted working hours and rules on hacking and debris disposal.
Should I move in before or after renovating?
After, if you can. Dust, wet works and carpentry are far easier in an empty unit, and you avoid living on a worksite.
