How to Extend House on a Budget: 5 Money Saving Tips

If the recent announcement of the Government’s home renovation grant has got you ready to add an extension to your home, you may be wondering where to start or if you can extend your house on a budget. While the home renovation grant is a great wallet boost, it’s important to be totally across the entire cost of a major renovation like an extension.

Here are a few insights into the cost of a home extension that may surprise you.

1. Single Storey vs Second Storey Extension Cost

If you’re considering a second storey extension, you may be expecting a bigger bill than that for a single storey extension. In most cases, a ground floor extension can actually cost more! Raising a home and building underneath doesn’t normally require foundations or a costly concrete slab, like a ground floor extension would. A ground floor extension could also require additional excavation work to level out sloping land.

2. Living On-Site Whilst Renovating

Despite second storey extension costs possibly saving you money during the build, you could find yourself losing money elsewhere - like in living expenses. It’s slightly harder to remain living in your home during the early stages of a second storey renovation, when you might be missing stairs to your front door! While it will depend on how your floor plan is being modified, in most cases it’s easier to remain living in the home during a single storey extension.

3. Beware of Bespoke Fittings Costs

The idea of large doorways and custom sized windows is appealing: until you get the bill. If your budget can afford bespoke fittings, then go for it - otherwise, cut costs by sticking with standard sized doors and windows for a cheaper approach to home renovation.


4. Measure Twice, Cut Once to Reduce Costs

Home renovation builders are usually pretty flexible and can modify certain aspects like powerpoint switches, floor levels, and even plumbing locations. However, last-minute changes could come with an extra cost. To save some cash, make sure you’re happy with your design before the build begins. That means planning out every little detail like powerpoint locations, light switch locations, and floor coverings. If you’re unsure on where to start, Hille’s building designers can work with you to ensure your needs and tastes are captured.

5. Don’t Forget About Those Little Extras

Rubbish removal, permits, approvals - on their own, these items don’t cost much but they quickly add up. Don’t forget that a home extension cost is not just about the designer, the builder, and the materials - it’s also about ensuring the worksite is clean and safe, and is operating according to all local and state regulations.
