About Ossher Design and Build
Second-storey addition builders in Sydney.
A second-storey addition is often the smartest move for a Sydney family home: more space, better light and long views, without the cost, disruption or approval risk of a knockdown rebuild.
Ossher Design and Build delivers second-storey additions across Sydney, with deep experience in the Eastern Suburbs. Founded by Adam Ossher, we manage structural coordination, DA submissions, program sequencing and finishes to a standard the home deserves.
We're familiar with Waverley, Woollahra and Randwick Council pathways and the structural realities of building on top of Federation, Edwardian, Inter-war and mid-century homes.

Local Knowledge
Second-storey additions in Sydney: what to plan for.
Adding a second storey is technically demanding. Here's how we approach it.
Structural Feasibility
Not every ground-floor home is ready to carry a second level as-is. We coordinate structural engineers early to establish what's viable and what needs strengthening.
Council & View-Sharing
Height, setbacks and view-sharing are common friction points. We prepare DA submissions with realistic massing that stands up to assessor scrutiny.
Living Downstairs
Most families stay in the home downstairs while we build above. We plan weatherproofing, dust control, access and noise windows carefully so daily life keeps working.
