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.
