Planning a major renovation or extension can be one of the most exciting stages of homeownership. Whether you're creating extra space for a growing family, modernising a tired kitchen, or adding a flatlet for rental income, renovations can significantly improve your quality of life and your property's value.
But here's the part most homeowners don't realise:
Just because you plan to spend R2 million on upgrades does not mean the bank will automatically agree that your home's value has increased by R2 million.
This matters - because the bank will only lend against the future value it is willing to recognise, not the total amount you plan to spend.
At Phoenix Bonds, we see this misunderstanding often. So here's a clear, no-nonsense guide to how renovation/building loans work, what banks look for, and how to structure your project to maximise both value and approval chances.
1. How Banks Assess Value on Renovation Loans
When you apply for a building or renovation loan, the bank asks for:
- Site plan / layout - usually with an area schedule
- A detailed builder's quote
- Schedule of finishes
- Signed building agreement with the total inclusive value of works
- Builder's NHBRC Certificate
The bank then sends out a valuer to estimate the post-renovation market value - essentially: What will this home be worth once all the work is completed?
And this is critical:
💡If you spend R2 million but the valuer believes the property value will only increase by R1.5 million… the bank can only lend up to that R1.5 million uplift.
This often surprises homeowners who expect the bank to fund the full project cost. But banks lend against value, not your budget.
This protects both you and the bank from over-capitalising in an area where buyers won't pay a premium matching your investment.
2. Renovations That Do Increase Property Value
Some upgrades reliably translate into higher valuations. Banks (and valuers) love these because they improve functionality, desirability, and marketability.
1. Kitchen Upgrades
The kitchen is the heart of the home - and the most influential space during a valuation.
Improvements that add value include:
- Full kitchen remodels
- Quality cabinetry
- Stone countertops
- Gas installations
- Modern appliances
- Improved layout
2. Bathroom Upgrades
Bathrooms are the second-biggest value driver.
Upgrades that add value include:
- Replacing older tiles and vanities
- Adding a second bathroom
- Modern sanitaryware
- Walk-in showers
- Better ventilation
3. Increasing Square Meterage
This is the strongest way to increase your property's value.
- Adding bedrooms
- Adding bathrooms
- Extending living areas
- Building a flatlet/cottage
- Converting a garage into habitable space (correctly, with plans)
Banks view new, legal, planned square meterage as a genuine uplift in value.
4. Structural Improvements
- New roofing
- Foundation strengthening
- Damp proofing
- Rewiring / plumbing upgrades
These often increase buyer confidence and valuation.
3. Renovations That Don't Add Much Value
These upgrades may make your home more enjoyable to live in - but they rarely translate into a high return on investment from a valuer's perspective:
Minimal or Limited Value Uplift
- High-end designer finishes beyond the area norm
- Swimming pools (maintenance = "buyer hesitation")
- Jacuzzis
- Fancy light fittings
- Imported tiles
- Costly landscaping
- Outdoor entertainment additions (without increasing sqm)
- Walk-in wine cellars
- Custom décor features
You may love these - but buyers (and valuers) don't always assign value to them.
If your renovation budget is tight, always prioritise kitchens, bathrooms, and liveable space.
4. Why Banks Approve the Loan But Don't Pay Out Immediately
Many homeowners are caught off guard by this rule:
🏗️ The bank will NOT release building funds until your architectural plans are fully approved by the municipality.
Approval of the loan is not the same as approval to begin construction.
Why?
Banks need to ensure that:
- The works are legal
- The municipality has approved the extra square meterage
- The project complies with safety regulations
- The final property matches the plans submitted for valuation
This is a critical step in preventing illegal additions - which South African banks will not fund.
Bottom line:
Your loan can be approved, but funds will stay frozen until your plans are approved.
This is normal. And it protects your asset.
