Thinking About a KnockDown Rebuild? Here's What You Need to Know First

Planning a knock down rebuild? Here are three essential site factors to consider before you get started.

A knock down rebuild is an exciting opportunity to start fresh with a brand-new home in a location you already love - but it’s not always as simple as it seems. Before you dive in, here are three critical factors to consider before moving forward.

1. Driveway Relocation
One of the most overlooked elements in a knock down rebuild is the existing driveway location. If your new home design requires a driveway in a different spot, it’s important to understand what’s involved.
On the Sunshine Coast, for example, driveway relocations often require a council application. Even if the relocation is approved, you'll likely need to reinstate the existing kerb and channel. If your block is free from street trees, power poles, or other council infrastructure, this process is much simpler - but every council is different, so allow time for approvals.

2. Block Gradient and Site Levels
Your block might look flat - but that doesn’t mean it is. To build a slab-on-ground home, the site needs to be close to perfectly level. A gentle-looking slope can still present major challenges.
We often receive knock down rebuild enquiries from homeowners who believe their block is flat, only to discover significant fall during site assessment. On one current project, we’re working with approximately 1.4 metres of fall from corner to corner.
In this case, retaining walls are required, and we’ll need to apply for an operational works permit to import fill and raise the site. These steps are essential to achieve a level platform for construction - and they can impact both timeframes and budget.

3. Fencing and Neighbouring Properties
When you change the levels of your site, you’re also changing how your property interacts with its neighbours.
If raising the ground level causes your site to overlook existing fencing, you may need to update or replace shared boundaries. In most cases, that involves having a conversation with your neighbours about cost-sharing and the style or height of the new fence. It’s best to address this early - before construction begins - to avoid disputes down the track.

The Bottom Line
A knock down rebuild is a fantastic way to build the home you really want - but it comes with a unique set of challenges. From council permissions to retaining walls and fencing conversations, understanding these factors upfront will help ensure a smoother journey from demolition to dream home.
