The Hidden Costs of Building a New Home: 10 Expenses You Should Budget For

Building a new home is exciting, but the final cost can be very different from the initial figure you have in mind. Many homeowners budget for bricks, concrete, roofing and finishes, but overlook the additional expenses that can quickly add thousands of rands to a project.

Before you start building, make sure your budget considers the full cost of the project, not just the obvious construction items.

1. Professional Fees

Architectural, engineering, quantity surveying and other professional services can form a significant part of your overall project cost.

2. Site Preparation

Clearing, excavation, levelling, soil conditions, retaining walls and difficult access can all increase costs before construction even begins.

3. Municipal and Service Connections

Water, electricity, sewerage and stormwater connections may involve additional fees and installation costs.

4. Design Changes

Changes made after construction has started can result in additional labour, materials and delays.

5. Material Price Increases

Construction material prices can change during a project. Steel, cement, timber and other materials can be affected by market conditions and supply costs.

6. Temporary Site Facilities

Site toilets, temporary electricity, water, storage and other site requirements are easy to overlook when preparing a budget.

7. Insurance and Compliance

Depending on the project, various insurance, compliance and inspection costs may need to be considered.

8. External Works

Driveways, paving, fencing, landscaping, boundary walls and other external works can add considerably to the final cost.

9. Finishes and Fixtures

Tiles, sanitaryware, taps, lighting, cupboards and other finishes can quickly push the budget higher—especially when the original allowances are unrealistic.

10. Contingency

Unexpected problems can happen on almost any construction project. Having a contingency allowance provides some protection against unforeseen costs.

Plan for the Full Cost

A realistic building budget is about much more than calculating a price per square metre. Every project has different plans, specifications, site conditions and requirements.
