If you are searching for a straight answer to “how much does a terrace house renovation cost,” most of what comes up is a single wide range with no context, RM50,000 to RM400,000 is a common one, from sites that have never actually delivered the work behind the number. The honest answer depends entirely on what “renovation” means for your terrace: a fresh coat of paint and new flooring is a different project from gutting the interior, and both are different again from extending the footprint.
This guide breaks terrace renovation cost down by scope, the way it actually gets quoted, using the same ranges we use with our own clients across Petaling Jaya, Subang Jaya, USJ, Puchong, and Kuala Lumpur.
Terrace Renovation Cost by Scope
Light refresh (2-3 rooms, cosmetic only)
RM 18,000 to RM 50,000
A light refresh covers painting, flooring touch-up works, and cabinetry touch-ups to two or three rooms, typically the kitchen and one or two bedrooms, without touching plumbing layout, electrical wiring, or structure. This is the entry point for owners who want the house to look and feel current without a full renovation timeline.
Full interior renovation
RM 50,000 to RM 100,000
A full interior renovation touches every room: kitchen, bathrooms, living and dining areas, bedrooms, flooring throughout, and a full repaint. For a typical single-storey terrace around 22 x 70 ft, a full interior renovation including tiling, carpentry, painting, and bathroom works generally falls between RM45,000 and RM80,000, depending on finish level and how much of the original wet area needs to be redone.
Full renovation with extension
RM 100,000 to RM 250,000
This tier covers a full interior renovation plus structural work: extending the kitchen or living area footprint, adding a room, or reconfiguring the roofline. Cost climbs here because extension work brings in structural demolition, new roof and beam work, and in most councils, authority submission before construction can start.
One of our own projects, a corner terrace in USJ 17, sits at this end of the scale. The scope included structural demolition and roof works to extend the home’s footprint, a full kitchen extension with new cabinetry, complete bathroom rebuilds, full retiling, and a full electrical rewire, delivered over twelve months. A project at that depth of structural change and duration is why “full renovation with extension” is a wide range rather than a single number.

| Scope | Estimated Cost |
|---|---|
| Light refresh (2-3 rooms, cosmetic) | RM 18,000 - RM 50,000 |
| Full interior renovation | RM 50,000 - RM 100,000 |
| Full interior renovation, typical 22 x 70 ft terrace | RM 45,000 - RM 80,000 |
| Full renovation with extension | RM 100,000 - RM 250,000 |
What Actually Drives the Cost Within Each Tier
Structural work
Any change to the building’s footprint or load-bearing elements, extensions, wall removal, roof modification, requires structural demolition, engineering input, and usually authority submission. This is the single biggest reason two “full renovation” quotes for the same house can differ by tens of thousands of ringgit: one includes structural change, the other does not.
Wet works
Bathrooms and kitchens are the most expensive areas per square foot in any terrace renovation. Waterproofing, replumbing, and full-height tiling in a bathroom typically run RM6,000 to RM20,000 per room depending on size and fittings, the same range we quote across property types in our general renovation cost guide.
Authority submission, where required
Structural extensions and footprint changes in most Klang Valley councils need building plan approval before work begins. Submission and permit costs start from RM3,000 and rise with complexity. A quote that skips this line item for an extension project is either assuming you will handle it separately or has not accounted for it at all, worth confirming before you sign.
Material tier
The same kitchen layout can cost RM15,000 or RM50,000 depending on whether cabinetry is laminate or solid wood, and whether countertops are standard quartz or imported stone. Get the material grade specified in writing in every quote you compare, not just a total figure.
Condition of an older terrace
Terrace houses built before the 2000s often have plumbing, wiring, and structural elements that were never designed for a modern renovation scope. Corroded pipework behind tiled walls, undersized electrical loads, and uneven original flooring are common discoveries once work starts, which is why a contingency of 10-15% on top of any quoted figure is worth budgeting for regardless of tier.
Why the Lowest Quote Is Rarely the Best One
If one quote comes in significantly below the others for what sounds like the same scope, the gap is almost always in what has been left out rather than in labour efficiency. Common exclusions in unusually low quotes: authority submission fees for extension work, waterproofing membrane in wet areas, or a lower material grade than what was discussed verbally. Our own guide to comparing renovation quotes covers how to line up quotes so you are comparing the same scope, not just the same total.
A reputable contractor should visit your terrace before quoting, not price it from photos or a floor plan alone. Age-related issues in older terraces, like the wiring and plumbing condition mentioned above, are usually only visible on site.
Getting an Accurate Quote for Your Terrace
- Decide which tier you are budgeting for: light refresh, full interior, or full renovation with extension
- Confirm whether your renovation requires authority submission, and ask each contractor whether that cost is included
- Get material grade specified by name or brand, not just “standard” or “premium”
- Invite at least three CIDB-registered contractors for a site visit and an itemised quotation
At Sun Synergy Contracts, every terrace renovation quotation is itemised by scope and fixed-price once agreed, so you know what you are paying for before work begins. Contact us for a site visit and an itemised quote for your terrace.
