Renovation cost per square metre (2026)
The clearest way to budget is by scope. These are indicative ranges for the area being renovated, with the total for a 150 m² house:
| Scope | Typical work | Cost / m² | 150 m² house |
|---|---|---|---|
| Light refresh | Painting, new flooring or tiles, ceilings, lighting, minor fittings | USD 50–120 | USD 7,500–18,000 |
| Standard renovation | New kitchen and bathrooms, electrics and plumbing, windows and doors, full finishes | USD 150–300 | USD 22,500–45,000 |
| Major renovation | Re-planning rooms, new roof, structural changes, new services | USD 300–450 | USD 45,000–67,500 |
| Extension or extra floor | New construction plus connecting it to the existing building | USD 300–500+ | A 40 m² extension is about USD 12,000–20,000 |
For comparison, building a new mid-range home runs about USD 425–500 per m². See our full guide to the cost to build a house in Rwanda.

What drives the price up or down
- Condition of the structure: cracks, damp, a weak roof or poor foundations are found once walls are opened, and they are the main source of surprises.
- How much you move: keeping the layout and the wet areas where they are is far cheaper than re-planning the house.
- Finishes: tiles, joinery and fittings can double a finishing budget.
- Services: rewiring and replacing old pipework add cost but remove the biggest long-term risks.
- Access and living on site: working around an occupied house takes longer.
What else to budget for
- Design and engineering: worth paying for on anything beyond cosmetic work. See architect fees in Rwanda.
- Permit: needed for structural changes, extensions and extra floors. See building permits in Kigali.
- Contingency: keep 15–20% aside. Older buildings hide problems.
- Somewhere to stay: if the work makes the house unliveable for a few weeks.
Renovate or rebuild?
If the structure is sound, renovating is usually cheaper and quicker. If the quote is heading towards 60–70% of the cost of building new, or the layout will never suit you, compare a rebuild before you commit. An architect and engineer can survey the building and give you both numbers.
Make it a green renovation
A renovation is the cheapest moment to cut your running costs. Better natural ventilation and daylight, shading, roof insulation, solar water heating, efficient lighting and rainwater harvesting are all easier to plan in now than to add later, and they pay back every month.
The most expensive renovation is the one you do twice. Survey first, design it properly, then build once.
