Most full-home renovations in Singapore need about 6 to 12 weeks of on-site work after the design, quotation, approvals and materials are settled. A straightforward BTO or new HDB flat may sit near the shorter end. A resale flat, full condo or landed home with more demolition, wet works, rewiring or custom carpentry usually takes longer.
That is only the construction period. Your real plan should also include design decisions, permit or MCST approval, material lead times, final cleaning, defect checks and a buffer before moving in.
Home Reno Pte Ltd handles HDB, BTO, condo and landed renovations in Singapore. This guide explains how to build a realistic schedule, which phases can overlap, and what commonly causes delays.
Quick Answer: How Long Should You Allow?
Use these ranges as early planning estimates, not promises. The final duration depends on the confirmed scope, property condition, approvals, access rules, material selection and contractor schedule.
| Property and scope | Practical planning estimate | What usually changes the duration |
|---|---|---|
| Focused room refresh | 2 to 6 weeks | Whether the work involves wet works, custom carpentry, rewiring or only surface finishes |
| BTO or new HDB flat | 6 to 10 weeks | Flooring, kitchen, wardrobes, lighting, painting and the amount of built-in work |
| Resale HDB flat | 8 to 12 weeks or more | Hacking, disposal, repair, waterproofing, rewiring, plumbing and replacement of old finishes |
| New or lightly renovated condo | 6 to 10 weeks | MCST approval, access restrictions, lift protection, carpentry and retained developer finishes |
| Resale or full-scope condo | 8 to 14 weeks or more | Removal work, layout changes, wet works, custom finishes and management requirements |
| Landed interior renovation | 12 to 20 weeks or more | Floor area, number of storeys, roof or facade work, structural scope and authority approvals |
A cosmetic refresh and a full renovation are not comparable. Ask for a timeline that names the actual work stages, not only a handover date.
Your Renovation Has Two Timelines
Homeowners often count from the first day workers arrive. A useful schedule starts earlier.
1. Pre-Construction Timeline
This covers the work needed before the site can start:
- Site visit, measurement and scope discussion
- Space planning and design development
- Itemised quotation and contract review
- Material, colour, fitting and appliance selection
- HDB permit, MCST approval or other clearances where required
- Ordering long-lead materials and confirming delivery dates
- Preparing the unit, access arrangements and neighbour notices
For a settled, straightforward scope, this stage may take about 2 to 4 weeks. It can take longer when the layout is still changing, approvals are needed, or imported materials and custom items are not yet available.
2. On-Site Renovation Timeline
This is the visible construction period: dismantling, hacking, wet works, services, carpentry installation, painting, fittings, testing and handover.
The two timelines are connected. If the drawings, materials or approvals are not ready, starting demolition early does not make the project faster. It creates idle days and raises the risk of rework.
Average Timeline By Property Type
BTO Or New HDB Flat
A BTO normally starts from a cleaner handover condition than a resale flat, so there may be less removal and repair. A typical full-home scope can still involve flooring, kitchen carpentry, wardrobes, electrical points, lighting, painting, plumbing fixtures and feature work.
Plan around 6 to 10 weeks on site for many standard scopes, plus pre-construction time. A lighter package with fewer built-ins may finish sooner. Extensive carpentry, tile work or late design changes can push it beyond the range.
Homeowners comparing room-count scopes can start with our BTO renovation packages, then confirm the actual duration after key collection and site measurement.
Resale HDB Flat
A resale flat usually needs more investigation and removal. Existing tiles, cabinets, wiring, plumbing, ceilings and previous renovation work may need to be dismantled, repaired or replaced before new finishes can begin.
Allow about 8 to 12 weeks or more on site for a fuller resale renovation. Older units or major layout changes can take longer, especially when hidden site conditions are discovered after dismantling.
Our HDB and condo packages provide starting scopes for new and resale HDB flats, executive apartments, maisonettes and selected room renovations.
Condominium
Condo renovation duration depends on both the work and the development’s rules. The management corporation may control working hours, contractor access, lift bookings, protection works, deposits and the approval documents required before work starts.
The Building and Construction Authority advises condo owners to check renovation restrictions with the developer or MCST. Structural elements such as slabs, beams, columns and walls cannot be altered without proper professional assessment and approval.
For planning, allow about 6 to 10 weeks for a lighter new-condo scope and 8 to 14 weeks or more for a resale or full-scope renovation. Obtain the management requirements early because every development is different.
Landed Property
Landed renovation ranges from one-room improvement work to a full multi-storey renovation. Interior-only work may take a few months. Structural changes, additions and alterations, roof or facade work, external drainage and major services can require professional design, authority submissions and a much longer programme.
For a substantial interior renovation, use 12 to 20 weeks or more as an early planning range. Treat additions, alterations and reconstruction as separate project types that need a project-specific schedule.
Browse our landed house renovation packages to separate room-specific work from a full-home scope before asking for a timeline.
What Happens During Each Renovation Phase?
The phases below do not simply add up. Good scheduling lets off-site carpentry fabrication, material ordering and some service work overlap safely.
| Phase | Typical allowance | What happens |
|---|---|---|
| Planning and design | 1 to 3 weeks | Measurement, layout, quotation, material selection and design confirmation |
| Approvals and procurement | Variable | Permit or MCST submission, long-lead ordering and delivery planning |
| Site protection and dismantling | 2 to 7 days | Protection, removal, disposal and preparation for new work |
| Hacking and demolition | 1 to 3 noisy-work days for many HDB scopes | Approved removal of finishes, fixtures or permitted walls |
| Masonry, waterproofing and tiling | 2 to 3 weeks | Screeding, wall work, waterproofing, curing and tile installation |
| Electrical and plumbing rough-ins | 1 to 2 weeks, often overlapping | New routes, points, pipes, testing and preparation before closing up |
| Carpentry fabrication and installation | 3 to 6 weeks, partly off site | Shop drawings, fabrication, delivery, fitting and adjustment |
| Painting, fittings and final installation | 1 to 2 weeks | Surface preparation, paint, lights, sanitary fittings, hardware and appliances |
| Cleaning, inspection and defects | 3 to 7 days | Cleaning, testing, snag list, rectification and handover |
Waterproofing, screed and sealants need proper curing time. Compressing those stages to recover a lost week can create leaks or finish failures that cost far more time later.
HDB Rules That Affect Your Schedule
Some HDB renovation work requires a permit, and HDB states that owners should only start those works after the permit is granted. The appointed contractor must be listed in HDB’s Directory of Renovation Contractors.
HDB’s current contractor terms also set clear working limits:
- Noisy work such as wall demolition, tile removal, tile cutting and heavy drilling is allowed from 9am to 5pm, Monday to Friday
- Noisy work is not allowed on Saturdays, Sundays, public holidays or the eve of major public holidays
- Noisy work must be completed within three consecutive days
- Other renovation work is generally allowed from 9am to 6pm on weekdays and Saturdays
- Renovation work is not allowed on Sundays and public holidays
These restrictions are why a three-day hacking window does not mean a three-day renovation. The remaining trades still need to follow their own sequence.
For current requirements, refer to HDB’s renovation permit guidance and terms for carrying out renovation work.
The Most Common Causes Of Renovation Delay
Design Changes After Work Starts
Moving a socket on a drawing takes minutes. Moving it after the wall is finished means opening the wall, rerouting the cable, making good and repainting. The same applies to tiles, plumbing points and built-in dimensions.
Freeze the layout, appliance models, sanitary fittings and main materials before the related trade begins.
Custom Materials And Carpentry
Imported tiles, special laminates, stone slabs, made-to-order fittings and custom carpentry can carry longer lead times. A promised delivery date should be checked before the site programme depends on it.
Approvals And Building Rules
HDB permits, MCST requirements and authority submissions depend on the scope. Submit the actual drawings early. Do not assume an approval time until the responsible party has checked the current requirements.
Hidden Site Conditions
Resale homes can hide corroded pipes, poor waterproofing, uneven walls, old wiring or previous unauthorised work. These problems may only become visible after removal.
This is why a realistic renovation budget and timeline both need contingency.
Poor Trade Sequencing
Carpentry, electrical, plumbing, tiling and painting depend on one another. A late measurement or missing fitting can block the next trade. A detailed schedule should show dependencies, not only dates.
Restricted Access And Working Hours
Condo loading bays, lift bookings, MCST working hours, neighbour rules and HDB noisy-work limits reduce the usable site hours. Include these constraints before confirming handover.
How To Keep Your Renovation On Schedule
- Confirm the scope in writing. List rooms, quantities, dimensions, materials, exclusions and owner-supplied items.
- Lock key decisions before the site starts. Finalise layouts, electrical points, sanitary fittings, tiles, laminates, worktops and appliances.
- Order long-lead items early. Check actual stock and delivery dates, not only showroom availability.
- Submit approvals with complete drawings. Missing information creates avoidable back-and-forth.
- Ask for a phase-based schedule. It should name demolition, wet works, services, carpentry, finishing and handover milestones.
- Hold a short weekly progress review. Compare completed work with the programme and decide any changes quickly.
- Approve variation orders before work continues. Record the added cost and the effect on handover.
- Keep a 1 to 2 week move-in buffer. Do not book movers for the same day as practical completion.
When Should You Plan To Move In?
Treat practical completion and comfortable move-in as two different dates.
After the main works finish, allow time for:
- Final cleaning and ventilation
- Defect inspection and rectification
- Appliance testing and installation
- Furniture, mattress and curtain delivery
- Internet activation and other services
- A final check that essential plumbing and electrical items work correctly
If temporary accommodation, a tenancy end date or school schedule makes the date critical, add at least 1 to 2 weeks of buffer after the contractor’s working handover date. A buffer is not wasted time. It protects you from turning one small defect or late delivery into an emergency move.
Frequently Asked Questions
How long does a typical HDB renovation take in Singapore?
Many full-home HDB renovations need about 6 to 12 weeks on site after the design, approvals and materials are ready. A BTO or lighter new-flat scope may be closer to 6 to 10 weeks. A resale flat with hacking, wet works, rewiring and more replacement work often needs 8 to 12 weeks or longer.
How long does a 4-room HDB renovation take?
A standard 4-room HDB renovation often falls within the same 6 to 12 week planning range. Room count alone does not decide the duration. The timeline changes more with demolition, wet works, carpentry quantity, electrical changes and material availability.
Is BTO renovation faster than resale HDB renovation?
Usually, yes. A BTO generally has less old work to remove and fewer hidden conditions. A resale flat may need hacking, repair, rewiring, plumbing replacement, waterproofing and levelling before new finishes can begin.
Can I speed up a renovation without compromising quality?
The safest gains come before construction: settle the design, order materials, complete approvals and coordinate appliances early. Do not save time by cutting waterproofing cure periods, skipping tests or closing walls before electrical and plumbing checks.
How much time should I add for HDB permits?
There is no single allowance for every project because permit requirements depend on the proposed work and supporting documents. Ask your HDB-listed contractor to identify the permits required and submit the completed application before the planned start date.
Why can a condo renovation take longer?
Condo projects must follow the development’s MCST rules in addition to any authority requirements. Access windows, lift bookings, protection, deposits, noisy-work restrictions and approval documents can affect both the start date and daily productivity.
Do I need to be at the renovation site every day?
No, but you should be available for scheduled milestone checks and quick decisions. Useful inspection points include after demolition, before concealed work is closed, after waterproofing or tiling, during carpentry installation and before handover.
Plan The Timeline Before You Book The Move
A reliable renovation schedule starts with a confirmed scope, not a guessed completion date. Share your property type, floor plan, key collection date, must-have work, material preferences and target move-in window. The project team can then identify approvals, lead times and the critical work sequence.
