About Ossher Design and Build
Woollahra is one of Sydney's most historically significant residential suburbs, tightly held Victorian and Federation terraces, grand family homes and streetscapes almost entirely covered by heritage conservation controls.
Ossher Design and Build delivers heritage renovations, sympathetic extensions and considered custom builds across Woollahra and the broader Eastern Suburbs. Founded by Adam Ossher, our work is built on integrity, craft and respect for the original fabric that gives these homes their value.
We have direct experience with Woollahra Council's heritage assessment and DA pathways, and we work alongside heritage architects, structural engineers and restoration specialists as required.

Local Knowledge
Woollahra builds are heritage-led and technically detailed. Here's how we approach them.
Almost every Woollahra project sits within a heritage conservation area. We prepare DA submissions that respect heritage controls while making a strong case for modern liveability.
Original joinery, plasterwork, cast-iron lacework and tessellated tiling all need specific approaches. We treat original fabric as something to work with, not around.
Woollahra terraces sit shoulder-to-shoulder. We plan crane access, party-wall protection, dust and neighbour notifications carefully so projects stay on program and relationships stay intact.

"Working with Adam was a genuinely great experience. The process was organised and far less stressful than expected, and the final quality and attention to detail were outstanding."
