Apartment Renovations · Sydney
High-end apartment renovations across Sydney's east, with strata approvals, common-property protection and building logistics managed as part of the build.

About Ossher Design and Build
Most builders avoid apartment work, and it shows. Strata approvals, lift bookings, work-hour limits, waste removal through shared corridors and waterproofing above someone else's ceiling all sit on top of the renovation itself.
Apartment buildings are Class 2 under the National Construction Code, and the work inside them is governed by the building's by-laws as much as by the code. Getting that wrong stalls projects for months; getting it right is process, not luck.
Ossher Design and Build delivers whole-apartment renovations, bathrooms, kitchens and joinery-led reconfigurations across Sydney's east, from art deco blocks in Potts Point and Elizabeth Bay to modern buildings in Bondi Junction and Double Bay.
We prepare the strata submission, coordinate with the building manager, protect common property and run the program to the building's rules, so you get a premium renovation without becoming a project manager.

Local Knowledge
Three things decide whether an apartment renovation is smooth or painful, and none of them are the tiles.
By-law review, approval submissions and building manager coordination are handled upfront. Nothing starts until the owners corporation has signed off.
Lift protection and bookings, loading windows, waste removal and daily common-area protection, all scheduled into the program rather than improvised.
Wet areas waterproofed to AS 3740 and documented, and flooring installed over acoustic underlay systems that satisfy both the by-laws and the neighbours below.

FAQs
Quality apartment renovations in Sydney's east generally run $2,500 to $4,000 per square metre. Restricted hours, lift-only access and strata requirements add cost compared to a house, and wet-area work carries the highest per-metre rate.
Yes for anything beyond cosmetic work. Waterproofing, flooring, structural changes and services work are minor or major renovations under NSW strata law and require owners corporation approval. We prepare the submission and supporting documents for you.
A single bathroom runs six to eight weeks. A full apartment renovation typically takes three to five months on site, plus four to eight weeks for strata approval and selections beforehand.
Yes. Older buildings often have stricter by-laws, smaller lifts and delicate common areas, which is exactly where a builder with a managed process matters most.
Yes. We hold a current NSW contractor licence and carry full public liability and home warranty insurance on every project.
Founder Adam Ossher runs every project personally, from feasibility through to handover. You deal with the person accountable for the build, not a rotating site manager.
