Knockdown Rebuild vs Renovation vs Extension: Which Is Right for Your Perth Home?

Choose a demolish and rebuild when your existing house no longer suits your block or your needs, a renovation when you want to keep the home and refresh how it looks and works, and an extension when you need more floor space and the existing home is worth keeping. BD Living Pty Ltd builds all three across Perth, so this guide compares them side by side.

What does a demolish and rebuild involve?

A demolish and build project removes your existing property and replaces it with a completely new home, instead of renovating an old structure. Our service covers demolition approvals, site preparation and construction. The main benefits are:

• A fresh home design that fits the way you live.
• Modern building standards and energy efficiency.
• No need to move away from your current location.
• Greater property value in the long run.

What does a home renovation involve?

Home renovations update the home you already own. They range from a full renovation of living areas, kitchens, bathrooms and outdoor spaces to remodelling an older layout so it is more functional. You can also renovate one room at a time with kitchen renovations or bathroom renovations.

What does a home extension involve?

A home extension adds space without moving. Options include single-storey and double-storey extensions, back extensions, house additions for extra bedrooms or an office, and garage conversions. A second storey addition builds up instead of out, which keeps your backyard and outdoor entertaining space intact.

How do you choose between them?

• Choose a demolish and rebuild if starting fresh makes more sense than upgrading the existing home piece by piece.
• Choose a renovation if you like the location and the home, and want updated layouts, kitchens or bathrooms.
• Choose a home extension if your household is growing and you want more rooms while keeping the existing house.
• Choose a second storey addition if you want extra bedrooms or living space without losing yard space.

What should you check before you decide?

Cost depends on size, materials and complexity, so ask for a written estimate that explains what is included. Ask who manages council approvals and permits, and whether the builder visits the site before quoting. BD Living starts every project with a consultation and site assessment and manages approvals and permits for you.
