About Ossher Design and Build
Elizabeth Bay is a quiet harbour pocket with a high proportion of significant art deco stock. The housing stock is dominated by harbourside apartment buildings and a small number of period houses, which means most briefs here are about premium apartment renovation with joinery-led planning rather than starting from scratch.
Ossher Design and Build is a licensed Sydney building company working across Elizabeth Bay and the surrounding Eastern Suburbs. Founder Adam Ossher is on every project personally, from the first feasibility conversation through to handover.
Practically, building in Elizabeth Bay means dealing with lift-access-only buildings, strict strata work hours and tight loading windows. Those conditions are not obstacles if they are planned for; they become expensive when they are discovered halfway through a program.
We work with City of Sydney on the approval pathway, coordinate architects, engineers and consultants, and run the build with weekly reporting so you always know where the program and budget sit.

Local Knowledge
Every suburb has its own constraints. These are the three that shape most Elizabeth Bay projects.
We assess the DA or CDC pathway at the start and prepare documentation that anticipates assessor questions, so approvals don't quietly consume months of your program.
Lift-access-only buildings, strict strata work hours and tight loading windows. We plan access, deliveries, protection and neighbour communication before the first trade arrives.
Harbourside apartment buildings and a small number of period houses. Working with existing structure means allowing for what's behind the walls, and pricing it honestly rather than as a variation later.
Most Elizabeth Bay sites have limited storage and shared boundaries. We schedule deliveries, agree noise windows and keep neighbours informed, which keeps complaints, and the delays they cause, off your program.

FAQs
As a broad guide, quality renovations in Elizabeth Bay start around $6,000 per square metre and new custom homes from around $8,000 per square metre. Lift-access-only buildings, strict strata work hours and tight loading windows can move that. We give you a real feasibility read at the first consultation rather than an optimistic number.
It depends on scope. Internal work in the existing footprint is often exempt or CDC. Anything changing footprint, height or external appearance generally needs a DA with City of Sydney, and heritage items or conservation area properties always need assessment.
Full home renovations typically run eight to fourteen months on site, and new builds fourteen to twenty-four months, plus approval time beforehand. We give you a program at quote stage and report against it weekly.
Yes. Premium apartment renovation with joinery-led planning is the most common brief we see in Elizabeth Bay, and we have the structural, approval and trade experience to run it end to end.
Yes. Federation, Victorian, Edwardian and interwar homes are a regular part of our work. We collaborate with heritage architects where required and prepare applications that anticipate heritage assessment.
Yes. We hold a current NSW contractor licence and carry full public liability and home warranty insurance on every project.
