About Ossher Design and Build
A heritage home isn't a problem to be modernised, it's a piece of Sydney's built history that deserves careful, considered work. The best heritage renovations preserve what makes the home significant while quietly lifting how it actually lives.
Ossher Design and Build delivers heritage renovations across Sydney, with deep experience in Federation, Edwardian, Inter-war and Californian bungalow homes across Paddington, Bondi, Bronte, Bellevue Hill, Vaucluse and the wider Eastern Suburbs.
Founded by Adam Ossher, our work is built on integrity, craft and respect for the original detailing, joinery, plasterwork and stonework that make these homes worth keeping.

Local Knowledge
Heritage projects carry a specific set of conditions. Here's how we approach them.
We work with restoration specialists for original joinery, plasterwork, leadlight and stonework, preserving what's significant rather than papering over it.
Heritage-listed and conservation-area projects need carefully prepared submissions. We work with heritage architects and consultants to give your DA the best chance of approval.
Insulation, services, glazing and waterproofing all need to be upgraded, but never at the expense of the home's character. We integrate them discreetly.
Most heritage renovations happen in occupied homes on tight sites. We plan dust, noise, protection of original detail and trade sequencing carefully throughout.
