Renovation costs in Cape Town vary enormously because “renovation” covers everything from a single repainted room to a full structural rebuild. As a rough starting point, online estimates for Cape Town renovations commonly range from around R2,500 to R15,000+ per square metre depending on scope — but a number that wide isn’t much use for planning your own project. What actually matters is what you’re changing, not just how big the house is.
What a Cape Town Renovation Actually Costs, by Project Size
At SmartCurve, our own completed projects fall into two broad bands. A small, focused update — retiling a bathroom, refreshing a kitchen, patching and repainting a room — typically runs from R15,000 to R30,000. A full renovation, covering multiple rooms, structural changes, or an extension, typically runs from R150,000 to R500,000+, depending on how much of the house is involved and how much needs to be stripped back before the finish work starts. Most homeowners land somewhere between those two extremes, and the honest answer is that nobody can tell you your exact number without seeing the property.

Two houses of the same size can cost very different amounts to renovate. The things that move the number most are:
- Whether plumbing or electrical points are moving, or staying where they are
- Whether any walls are structural, and whether a wall is coming down at all
- The finish level — standard tiles and fittings vs. imported or premium materials
- How much prep work is needed before the visible work even starts (stripping old finishes, fixing what’s underneath)
- Access — a City Bowl apartment with limited parking and lift access costs more to work on than a freestanding suburban house
Kitchens and Bathrooms Usually Cost the Most
Room-for-room, kitchens and bathrooms are consistently the most expensive spaces to renovate — not because of size, but because of what’s involved: plumbing, waterproofing, electrical work, and specialised cabinetry all stack up in a relatively small footprint. A lounge repaint and a bathroom retile might cover similar square metreage, but the bathroom will almost always cost more. In a bathroom specifically, waterproofing is the line item people underestimate most — it has to be done properly before a single tile goes down, and redoing it later because it was skipped or rushed costs far more than getting it right the first time.

A few costs regularly catch people out, especially on older Cape Town properties:
- Council building plans — if you’re changing the external footprint or removing a structural wall, you’ll need an approved building plan from the City of Cape Town before work starts, which adds professional fees and a real approval delay (budget for weeks, not days).
- A structural engineer’s sign-off — required by law if you’re removing a load-bearing wall or adding a second storey.
- Heritage permits — if your home is in an older Cape Town suburb (City Bowl, Bo-Kaap, and similar heritage areas) and is more than 60 years old, you may need a Heritage Western Cape permit before any structural work begins.
- Debris removal — rubble and skip hire is a real line item, not an afterthought.
- A contingency buffer — older Cape Town homes regularly hide damp, outdated wiring, or degraded plumbing behind the walls. A sensible buffer (most guides suggest 10–15%) covers what a contractor genuinely can’t see until demolition starts.
How to Get a Quote You Can Actually Trust
Because the real number depends entirely on your specific house, the only way to get a figure worth planning around is a proper site visit — not a per-square-metre guess. Before you commit to any renovation company, it’s worth asking a few direct questions: is the quote written and itemised, not verbal? Does it separate out prep and waterproofing as their own line items, rather than folding them into “tiling”? And does the company doing the quoting actually do the work, or is it being handed to a subcontractor once you’ve signed? Getting these wrong is exactly how a straightforward renovation turns into one of the biggest mistakes Cape Town homeowners make.
