About Ossher Design and Build
Knockdown rebuild specialists in Sydney.
When an existing home can't be renovated to meet your needs cost-effectively, a knockdown rebuild is often the smarter long-term move. You keep the land you love and get a home that's genuinely designed for how you want to live.
Ossher Design and Build delivers end-to-end knockdown rebuilds across Sydney, with a particular focus on the Eastern Suburbs. Founded by Adam Ossher, we manage demolition, approvals, architectural coordination and construction as one continuous program, so nothing falls between the cracks.
Whether your block sits in Bondi, Randwick, Vaucluse or elsewhere across Sydney, we'll give you an honest read on whether to renovate or rebuild, based on what genuinely delivers better value.

Local Knowledge
Sydney knockdown rebuilds: what's involved.
A knockdown rebuild has more moving parts than a standard build. Here's how we manage them.
Demolition & Site Prep
We coordinate licensed demolition, asbestos handling, service disconnections and site clearance so the new build starts on a clean, properly prepared site.
Council Approvals
Knockdown rebuilds usually require DA approval, and sometimes heritage assessment. We prepare submissions across Waverley, Woollahra, Randwick and other Sydney councils and manage assessor queries on your behalf.
Custom Home Construction
We work with your architect, or recommend one, to deliver a home designed for your block, your brief and your budget, not a project-builder template.
