About Ossher Design and Build
Double Bay is a mix of grand harbourside homes, refined apartments and tightly-held blocks where every project carries an expectation of discretion and finish.
Ossher Design and Build delivers custom homes, major renovations and high-end apartment refurbishments across Double Bay and the broader Eastern Suburbs. Founded by Adam Ossher, we bring craftsmanship, transparent communication and a respect for client time to every project.
We have direct experience with Woollahra Council DA pathways, body corporate coordination, and the access constraints common in Double Bay's denser pockets.

Local Knowledge
Double Bay builds bring specific logistical and approval challenges. Here's how we manage them.
We prepare DA and CDC documentation tailored to Double Bay's heritage and streetscape controls, reducing back-and-forth and protecting your timeline.
Many Double Bay projects sit inside strata buildings. We coordinate body corporate approvals, neighbour notifications and works schedules to keep projects moving.
Narrow streets and limited site storage are the norm. We plan crane movements, deliveries and waste removal upfront to avoid mid-build disruption.
