What Do Popular Renovation Projects Cost?
Here are the most requested renovation projects in Johannesburg with current 2026 pricing:
Open-Plan Conversion: R25,000 – R80,000
Removing a wall between kitchen and living room creates a modern open-plan layout. Cost depends on whether the wall is load-bearing (requires steel beam and engineer, R15,000–R40,000 more) or a partition wall (simpler removal and make-good).
Garage Conversion: R120,000 – R350,000
Converting an unused garage into a home office, granny flat, or entertainment room. Includes insulation, electrical, plumbing (if adding bathroom), plastering, flooring, and finishing.
Granny Flat Addition: R350,000 – R750,000
A self-contained 40–60 m² unit with bedroom, bathroom, kitchen, and private entrance. Requires council-approved plans. Generates R7,000–R14,000/month rental income — an 18–25% annual return.
Do You Need Building Plans for a Renovation?
Most cosmetic renovations do not require building plans, but any structural changes do. Here is the breakdown:
Plans required for:
- Removing or modifying structural/load-bearing walls
- Adding rooms or extensions
- Changing the roofline
- Adding or relocating plumbing and drainage
- Any work that alters the building footprint
Plans NOT required for:
- New kitchen cabinets and countertops (cosmetic)
- Bathroom retiling and new fixtures (cosmetic)
- Painting (interior and exterior)
- New flooring
- Built-in cupboards

How Long Does a Renovation Take in Johannesburg?
A kitchen renovation takes 2–4 weeks, a bathroom 2–3 weeks, and a full house renovation 8–16 weeks, assuming approved plans are in place:
| Project | Typical Duration |
|---|---|
| Kitchen renovation | 2–4 weeks |
| Bathroom renovation | 2–3 weeks |
| Open-plan conversion | 3–6 weeks |
| Full house renovation | 8–16 weeks |
| Garage conversion | 4–8 weeks |
These timelines assume approved plans are in place. The council approval process adds 4–12 weeks for structural work.
How Can You Keep Your Renovation on Budget?
The most important rule is to fix your scope before construction starts — changes during a build cost 3–5x more than changes on paper. Here are seven proven budget strategies:
- Fix the scope before you start — Changes during construction cost 3–5× more than changes on paper
- Get an itemised quote — Every material, quantity, and labour item should be listed. "Allowances" and "TBC" items are budget traps
- Budget 10–15% contingency — Every renovation uncovers surprises behind walls (old wiring, hidden damp, rotten timber)
- Don't move plumbing unless you must — Relocating pipes and drains is expensive. Keep the sink, toilet, and shower in their current positions if possible
- Invest in waterproofing — R2,000 for bathroom waterproofing prevents R50,000+ in leak damage later
- Choose one contractor for all trades — Multi-trade coordination under one project manager avoids scheduling conflicts and finger-pointing between trades
- Agree payment milestones — Never pay more than 30% upfront. Tie payments to completed work stages
