Renovating your home is exciting but it’s also a significant investment, and the costs can sometimes surprise you if you’re not prepared. At AVK Homes, we believe that understanding where your money is going is the best way to keep your project on track and stress-free.

In this guide, we’ll walk you through the common cost drivers to be aware of during a major renovation:

1. Demolition and Site Preparation

Before new work begins, the old needs to come out. Demolition can range from removing a few internal walls to completely gutting a section of your home. Costs vary depending on access, waste removal, and the presence of materials that require special handling (like asbestos).

Tip: factor demolition into your upfront budget, rather than treating it as an afterthought.

2. Structural Changes

Altering a home’s structure such as moving walls, raising ceilings, or adjusting rooflines is one of the biggest cost drivers. These works often require:

• Structural engineering input
• Council approvals or permits
• Skilled trades for framing and support

The more extensive the changes, the higher the cost.

3. Services and Utilities

Updating or moving plumbing, electrical, and HVAC systems can be complex, particularly in older homes. It’s common to find outdated electrical wiring, insufficient drainage, or non-compliant systems (like insufficient insulation or ventilation) during a renovation.

4. Materials and Finishes

The finishes you choose have a major impact on cost. For example:

• Tiles and tapware range from budget-friendly to high-end designer
• Flooring options vary significantly in price and durability
• Custom cabinetry is more expensive than modular units

A helpful approach is to prioritise investment in high-use areas (like kitchens and bathrooms) while being more conservative in secondary spaces.

5. Hidden Fixes

Sometimes the most important work is the part you can’t see like addressing water damage, termite issues, or foundation repairs. These aren’t the most glamorous parts of a renovation, but they’re essential to fix properly for the long-term health of your home.

Tip: build a contingency of 10–15% into your budget to cover these surprises without derailing your project.

6. How AVK Homes Keeps You on Track

Understanding these cost drivers will help you plan more effectively. The best way to stay in control is to:

• Start with a clear and detailed scope of works
• Factor in a realistic budget for structural and service upgrades
• Allow room for contingencies
• Prioritise your spend on what matters most to your lifestyle
