Raising a Flood-Affected Home
House raising and flood recovery in the Northern Rivers NSW — how raising an existing home works, when it suits, and how it fits flood-planning levels and approvals.
For homes on the Northern Rivers floodplains, raising the house is one of the most effective ways to reduce flood risk while keeping the home you have. After the 2022 floods it has become a central part of recovery across the Richmond, Wilsons and Clarence valleys. This guide explains how house raising works and when it makes sense.
It is general guidance rather than advice for your specific home. When you are ready to look at your own block, get in touch and we will give you answers grounded in your flood level and the way your house is built.
How house raising works
Raising a home lifts the existing structure and sets it on new, taller supports so habitable floors sit above the flood-planning level. It suits timber-framed homes on piers more readily than slab-on-ground houses, which are harder and costlier to raise. The space created underneath can be left open, used for parking and storage, or partly enclosed within the flood rules. How high the home goes is set by the flood-planning level mapped for the block, not a one-size figure.
When raising suits, and what is involved
Raising tends to suit a structurally sound home in a location worth staying in, where the flood exposure is the main problem rather than the house itself. The work involves engineering, council approval, disconnecting and reconnecting services, and making good the home once it is up. In the Northern Rivers, support schemes have at times been available to help flood-affected owners raise or repair, so it is worth checking your eligibility as part of planning. We assess whether raising is the right path for your home or whether a rebuild makes more sense.
Questions
- Can any house be raised?
- Not equally. Timber-framed homes on piers are the most straightforward to raise; slab-on-ground homes are much harder and more expensive, so a rebuild is often the better path for them. The home also needs to be structurally sound. We assess your house and its flood level to advise whether raising suits.
- How high does a raised home need to be?
- The height is set by the flood-planning level mapped for your block, so it varies from home to home rather than being a single figure. We confirm the level the council holds for your address and design the raise to meet it.
