Discreet, architecturally-led custom homes and major renovations across Sydney. Deep experience in the Eastern Suburbs. Founder-led by Adam Ossher.

About Ossher Design and Build
A luxury home in Sydney is among the most ambitious residential briefs in the country, significant scale, demanding finishes, intricate engineering and an expectation of discretion from feasibility through to handover.
Ossher Design and Build delivers architectural custom homes and major renovations across Sydney, with a particular focus on the Eastern Suburbs including Bellevue Hill, Vaucluse, Double Bay, Point Piper, Rose Bay and Bondi. Founder Adam Ossher is personally on every project, working alongside leading architects, interior designers and consultants.
Woollahra, Waverley and Randwick Council DA pathways are well understood ground for us, and our work spans Federation restorations, harbourside new-builds and full-scope renovations visible in the portfolio.

Local Knowledge
These are technically demanding, operationally complex projects. Here's how we approach them.
We treat client privacy as a default, not an upgrade. Site management, deliveries and sub-contractor conduct are coordinated with the discretion these projects require.
Sydney DAs at this scale often involve heritage assessment, view-sharing and detailed neighbour notification. We prepare submissions that hold up to scrutiny.
Steep blocks, deep basements, complex glazing and bespoke joinery are common. We coordinate consultants, lead times and tolerances so the finished work meets the closest inspection.
