Resale condo renovation in Singapore begins with a decision: what is worth keeping, and what needs to change before you move in? An existing kitchen, wardrobe or bathroom may look presentable, but its condition, layout and compatibility with your household determine whether retaining it is sensible.
Before comparing renovation quotations, assess the unit, obtain the estate’s renovation requirements and prepare a room-by-room scope. This gives your interior designer a stronger basis for planning the home and helps you avoid unnecessary replacement or overlooked repairs.
This guide is for homeowners renovating a purchased resale condominium for their own use. It focuses on defining the work and preparing for a quotation, rather than new-launch furnishing packages or renovation for resale profit.
Do you need a refresh, partial renovation or full overhaul?
The age of a condominium does not determine the scope on its own. Inspect the unit and compare its layout with how you intend to live. A relatively recent home can still need substantial changes, while an older unit may contain serviceable features worth retaining.
A light refresh
A refresh may suit a home whose layout, kitchen, bathrooms and services remain suitable after assessment. Work could include repainting, selected lighting improvements, loose furniture and targeted storage. Check retained elements before designing around them, and specify protection for anything that stays.
A partial renovation
A partial renovation concentrates on specific rooms or systems, such as replacing a kitchen, improving bedroom storage or upgrading a bathroom. Pay attention to the junction between new and existing work: floor levels, tile edges, cabinet finishes and electrical routes can affect both appearance and cost.
A full renovation
A wider renovation may be appropriate when the layout and finishes no longer suit the household or several systems need attention. It requires a coordinated scope and a programme that includes approvals, procurement and testing. Extensive work should follow an assessed need, not an assumption that everything must be replaced.
What affects resale condo renovation cost?
A meaningful budget depends on quantities, specifications and site conditions. Floor area alone cannot tell you how much cabinetry must be rebuilt, whether concealed services need replacement or how much work is required in wet areas. Treat an advertised package as a starting scope to examine, not a confirmed price for your unit.
- Existing condition: repairs, removal work and access to concealed installations can change the scope.
- Kitchen and bathroom work: replacement extent, service locations and interfaces with retained finishes matter.
- Carpentry: cabinet dimensions, internal fittings, hardware and finish specifications should be itemised.
- Electrical and air-conditioning work: assessment, replacement and new routes should be identified separately.
- Materials: compare the specified product and installation method, not only a showroom sample.
- Estate logistics: permitted work periods, delivery access and protection requirements affect planning.
Separate the renovation contract from appliances, furniture, curtains, moving expenses and temporary accommodation. Ask which professional fees or estate-related charges are included, and whether GST is included where applicable. Agree an allowance for unresolved conditions based on actual risks found during assessment.
For example, two same-size units may need different budgets if one retains usable flooring and a suitable kitchen while the other replaces both and alters service routes. Ask for the differences to be priced explicitly instead of relying on a single per-square-foot comparison.

Build a retain-or-replace checklist before design starts
Kitchen cabinets and appliances
Inspect cabinet interiors, hinges and areas around the sink for damage. Check whether the layout gives you useful preparation space and whether your chosen appliances fit existing openings. Replacing only doors may not solve problems with cabinet carcasses or layout; ask the contractor what can realistically be retained.
Bathrooms and wet areas
Record staining, damaged sealant, drainage concerns or previous repairs and arrange appropriate investigation. A new surface finish is not a diagnosis of an underlying water problem. Before specifying an overlay or replacement, ask how the proposed work addresses the existing condition.
Flooring and junctions
Discuss the suitability of retaining, repairing or replacing the flooring. If overlay is proposed, review door clearances, transitions and interfaces with built-in furniture. Ask how damaged areas will be treated and whether matching material is available for local repairs.
Electrical and air-conditioning installations
Provide appliance and room-use plans to the relevant trades for assessment. Do not assume the property’s age automatically determines whether every installation must be replaced. Obtain a defined recommendation and scope, including access, making good and testing.
Wardrobes and other built-ins
Measure useful storage rather than counting doors. Consider hanging length, luggage, cleaning tools and daily access. Keep serviceable storage that fits your needs; replace or adapt items that force an awkward furniture arrangement or no longer work properly.
Check MCST requirements before confirming the programme
Obtain current renovation application requirements from the managing agent or MCST. BCA advises condo owners to check renovation restrictions and explains that structural alterations require proper assessment and approval. External features and common property can involve additional permissions. Refer to BCA’s guidance for condo owners.
Do not treat management consent as a substitute for statutory approvals. BCA notes that some minor works are exempt from plan submission, but other applicable requirements remain. Have a Qualified Person advise on clearances for proposed building works when necessary; see BCA’s explanation of works not requiring plan approval.
Ask the managing agent to confirm these details for your estate:
- Application documents, drawings and contractor information.
- Any renovation deposit, insurance documentation or administrative charges.
- Working periods and separate restrictions for noisy work.
- Lift booking, delivery, debris removal and common-area protection.
- Requirements affecting windows, balconies, external appearance or shared services.
- Completion checks and the process for closing the application.
These arrangements are estate-specific. Avoid setting your move-in date from a construction estimate before the applicable requirements and access arrangements are understood.
Improve the layout without unnecessary built-ins
Begin with the furniture you use every day: sofa, dining chairs, beds, desk and storage. Draw these at their actual sizes and test doors, drawers and walkways in their open positions. This often reveals a more useful design decision than adding another feature wall.
In a compact living-dining area, consider whether a smaller table or shallower cabinet preserves the route to the bedrooms and balcony. Check wardrobe access with the chosen bed in place. A study niche should have suitable seating, light and power rather than simply occupy an unused corner.
Keep access to service points in the carpentry plan. Ask how equipment can be maintained or replaced without dismantling large sections of cabinetry. Crown Interior Design’s residential design and custom carpentry services can help you discuss these requirements as part of a coordinated brief.
What should a resale condo renovation quotation include?
Request a quotation tied to the agreed layout and a list of retained items. Identify work by area or trade, with quantities and specifications. If the unit cannot yet be fully inspected, mark assumptions and explain how pricing will be reviewed once access is available.
- Demolition, disposal and protection of retained finishes.
- Repair and preparation before new finishes are installed.
- Carpentry dimensions, materials, hardware and internal fittings.
- Electrical, plumbing and air-conditioning scope, including making good.
- Responsibility for applications, specialist assessment and fees.
- Excluded appliances, loose items and owner-supplied products.
- Payment milestones, written variation procedures and handover checks.
- Defects reporting arrangements and stated warranty scope.
Compare a consistent scope across proposals. If one designer recommends retaining an element and another recommends replacement, ask each to explain the condition or functional issue behind that recommendation.
Plan backwards from your intended move-in
Allow for more than on-site work. The sequence may include access and measurement, design, estate coordination, required approvals, ordering, installation, testing and rectification. Ask which milestones depend on final selections or outstanding information.
Confirm appliance dimensions before cabinetry is fabricated. Coordinate furniture delivery after relevant work and cleaning are complete. Keep time between practical completion and moving day for checking doors, drawers, fixtures and agreed installations with the team.
If you need to live in the unit during renovation, discuss feasibility before committing. Work affecting bathrooms, kitchen use, power or access may make a temporary move more practical. Assess phasing against the actual work and household needs.
Send a clear brief to Crown Interior Design
Prepare your condo name, floor plan, approximate floor area, photographs and access date. Add household requirements, your intended move-in date, budget range and a room-by-room list of what you hope to keep or change.
Include the estate’s renovation information if available, plus known issues or past repairs. You do not need a finished design before enquiring; identifying the decisions you need help with gives the discussion direction.

Frequently asked questions
Is renovating a resale condo always more expensive than a new condo?
Not necessarily. Condition, scope and specification matter more than the label. A resale refresh can involve limited work, while extensive customisation of a new unit can have a substantial scope. Compare defined requirements rather than assuming a fixed premium.
Can I remove a wall inside my condo?
Do not decide from appearance or a sales floor plan alone. Obtain appropriate assessment of the wall and proposed work, then confirm applicable estate and authority requirements before including removal in the final scope.
Can I keep the kitchen and renovate the rest of the home?
Potentially, if its condition and layout remain suitable. Check connections with surrounding work, appliance compatibility and protection needs. Specify retained items so the quotation and site team work from the same plan.
How long will the renovation take?
A realistic programme needs the confirmed scope, access arrangements, required clearances and material lead times. Ask for a project-specific sequence with dependencies, not only an estimated number of construction weeks.
Should I obtain a quotation before getting the keys?
You can begin discussing requirements using plans and photographs, but a preliminary estimate should state its assumptions. Arrange inspection and measurement when access is available before treating the scope and price as final.
Make the renovation fit the home you actually bought
A well-planned resale condo renovation starts with the existing unit, not a generic package. Assess what can remain, resolve restrictions early and invest in changes that improve daily living. Contact Crown Interior Design to discuss your floor plan, priorities and next steps.
