Renovating an Old or Resale Home, Done Right
Resale condos and older HDB flats need more than a fresh coat of paint — they need someone who knows what to keep, what to replace, and what to rebuild. CASAWAVE leads with custom furniture and coordinates the renovation around it, so your budget goes where it matters most.
The biggest risk isn't the cabinets — it's what's behind the walls
An old or resale home carries the decisions, wear and quiet problems of the years before you. The visible upgrades are easy to budget; the real risk is what's uncovered once work begins — ageing wiring, old pipework, degraded waterproofing, and how well the previous renovation was actually built. Renovating an older home well isn't about tearing everything out. It's about knowing what genuinely needs to change, and planning for what you can't see.
Our approach: we help you sort what should be kept, replaced or rebuilt before setting the budget — then lead with the custom furniture that shapes daily living, and coordinate the base works around a clear plan. It's the honest way to renovate an older home without overspending on the wrong things.
One team for the carpentry and the base works
Most renovation quotations arrive before anything has been designed. We work the other way round. The carpentry is designed first — because it decides where power points, water points and ceiling drops actually have to go — and only then is the base renovation designed, drawn and priced against a layout that already exists. A number quoted before the drawings exist is a placeholder, not a price.
Requirements, then a layout plan
How the home is actually used, turned into a dimensioned layout before anything is styled.
Whole-home design in 3D
Every room modelled in the finishes specified for your home. You confirm style and furniture here.
Services and ceiling drawings
Electrical, plumbing and ceiling construction drawings, set against the carpentry that is going in.
Carpentry structural CAD
The furniture drawn as a structure the factory cuts from, plus the junction details where it meets the base works.
Then the base works are priced
Quoted line by line against every drawing above, which leaves very little for a mid-project addition to appear in.
Built and checked to the drawing
Dated schedule, our own project manager on site, and work accepted against the drawings it was priced from.
Priced to the drawing. Built to the drawing. Checked against the drawing.
The same project can run through to the last layer — sofa, dining table, curtains, lighting and decorative pieces specified and installed with the rest of the home. Three designers work on every project: a whole-home designer, a carpentry detailing designer and a soft furnishing designer. See the full whole-home process →
Renovation guides by property type
Whether you've bought a resale condo or an older HDB flat, start with the guide that fits your home — each covers what to prioritise, the hidden risks, and how to plan sensibly.
Resale Condo
Older condos need more custom carpentry than a new unit. Learn what to keep, replace or rebuild, and what to tackle first after collecting your keys.
Resale & Older HDB
From a recently bought resale flat to a 20-year-old home, understand the keep-replace-rebuild decision and where your budget is best spent.

The spaces that matter most in an old home
In most older homes, the kitchen, wardrobes and bathrooms are where daily life is most affected — and where custom furniture makes the biggest difference. Explore each:
Old Kitchen
An old kitchen doesn't always need a full gut-out. Understand your options — refresh, partial rework, or full custom rebuild — and how to choose.
Wardrobes & Storage
Old wardrobes are often shallow and poorly divided inside. Plan storage around how you actually live — it's what makes an older home feel calm.
Bathrooms
In an older home, bathroom waterproofing is often at the end of its life. Redo it while it's open, and upgrade the vanity into a real storage system.
Whole-Home Approach
When several spaces need work at once, a coordinated whole-home plan keeps the finishes consistent and the project accountable to one team.
European materials, our own craftsmen
Custom furniture is the core of an old-home renovation — it is what you touch every day, and the part most likely to disappoint a year later. We came into whole-home renovation from that core outwards, which is why the two trades we keep in house are the two that decide how a finished home actually looks.
European boards and hardware
Our whole-home carpentry runs on European board — EGGER and CLEAF decors with BLUM hardware, at F★★★★ emission grade. The specification is written into the quotation, not left as “or equivalent”.
Made in a factory, not improvised on site
Panels are cut and laser edge-banded on factory machinery to a drawing. Edges come back sealed with no visible glue line, and two identical doors are actually identical.
Our own carpentry installers
Installation is handled by our own experienced craftsmen rather than a crew booked for the week — reading real wall and floor conditions in an older flat, and answering to the same project manager who drew the schedule.
Our own tilers
Tiling is usually the largest single line in a Singapore renovation, and the one where the finished result varies most from crew to crew. Ours are our own experienced tilers, on the same drawings and the same supervision.
Certified low-emission boards — not just a claim
Indoor air quality matters most in an enclosed home filled with built-ins. The boards we use are independently tested and certified to the highest emission grade — here's the proof, not just our word.
FUREN board, independently tested
This test report from the Research Institute of Wood Industry, Chinese Academy of Forestry — a national wood-based panel testing centre — certifies the FUREN board we use at the F★★★★ grade, the highest low-formaldehyde-emission classification. It covers formaldehyde emission, TVOC over 7 days, and a full range of physical performance tests.
For an older home being filled with new cabinetry, this is the kind of evidence worth asking any renovator for. We're happy to show the full certificate at our showroom.
Our own team, on real Singapore projects
The custom furniture in an old-home renovation is only as good as the team that installs it. These are our own craftsmen on real projects — not stock photos.
