Second-Storey Additions

Second-storey additions across the Northern Rivers NSW. Structural assessment, engineering, build. Licensed builder.

Adding a second storey to an existing single-storey home keeps you on the same block while doubling your habitable area. It's a technically complex job: the existing footings and walls have to take the new load, the existing roof has to come off, weather sealing has to hold through the work, and finish work has to integrate both old and new.

Riversedge Building Group runs second-storey additions across the Northern Rivers. The very first step on every job is a structural engineer assessment of the existing footings and load path — we don't quote a second-storey until that's confirmed.

When a second storey works

Modern post-1990 homes on concrete slabs typically support a second storey with little or no underpinning. Older timber-stumped homes, brick-veneer homes with shallow footings, or homes with internal beam-and-post systems may need significant remedial work first — sometimes enough that an extension or KDR is the better economic answer.

Keeping the home weathertight during the build

The challenging phase of a second-storey addition is the period after the existing roof comes off and before the new upper level is closed in. We plan this around the weather, stage the work to keep that window short, and use temporary weather protection over the opened structure so the ground floor and your belongings stay dry. How we sequence it is set out before the build starts.

Frequently Asked

Questions

Do I need to move out for a second-storey addition?
It depends on the home and the stage. The ground floor is often usable for parts of the build, but the noisiest and most exposed phases — particularly when the roof is off — can call for a temporary move. We give you a realistic read on this for your specific house before contract.
How do you know my house can carry a second storey?
The first step on every second-storey job is a structural engineer's assessment of the existing footings and load path. We don't quote the addition until that assessment confirms what the home can carry and what, if any, strengthening is needed.
