About Ossher Design and Build
Home extension specialists across the Eastern Suburbs.
A well-designed extension can transform how an established Eastern Suburbs home performs, more light, better flow, a proper connection to the outdoors, without the cost and disruption of a full rebuild.
Ossher Design and Build delivers rear extensions, side extensions and second-storey additions across Bondi, Bronte, Coogee, Randwick, Vaucluse, Double Bay, Paddington, Bellevue Hill and the wider Eastern Suburbs. Founded by Adam Ossher, our work is built on integrity, craft and clear communication from feasibility to handover.
We're familiar with Waverley, Woollahra and Randwick Council DA and CDC pathways, heritage overlays that shape many extension briefs, and the tight-site logistics that come with building against an occupied home.

Local Knowledge
Extending in the Eastern Suburbs: what to plan for.
Extensions here are rarely simple. Heritage controls, tight sites and the challenge of building onto an existing structure all shape the approach.
Structural Integration
Tying new work into an existing home means understanding the original structure. We coordinate structural engineers early so junctions are properly detailed, not improvised on site.
Council & Heritage Overlays
Waverley, Woollahra and Randwick each have their own pathways. We prepare DA and CDC submissions with an honest read on what your extension can and can't achieve.
Living Through the Build
Most extensions happen in occupied homes. We plan trade sequencing, dust control and noise windows so the project stays as livable as possible while it's underway.
Tight sites & access
Extensions on tight Eastern Suburbs blocks demand careful planning. Crane access, party-wall protection, neighbour notifications and delivery windows all get planned before demolition, not during it.
