Renovations and extensions
Whole home renovations, rear and side extensions and second storey additions for terraces, semis and freestanding homes.
Home renovationsShafbuild is a design and construct builder based at 49 Boronia St, Kensington. We renovate, extend and build homes across the Eastern Suburbs, deliver remedial works for strata buildings, and fit out commercial spaces, with one team accountable from the first site visit to handover.
We are a licensed builder (licence 469244C) and a registered NSW Class 2 Building Practitioner (BUP4254234), so we can take on the apartment and strata work that makes up so much of this part of Sydney.




The same team runs design, approvals and construction on every job, whether it is a terrace renovation in Paddington or balcony remediation in Coogee.

Remedial and strataKnock down rebuilds, custom homes and dual occupancy, from feasibility and approvals through to handover.
New buildsOffice, hospitality, retail and education fitouts, programmed around trading hours and term dates.
Commercial workArchitecture, engineering, planning and DA or CDC approvals led in-house, so the design is priced and buildable before you commit.
Design and approvalsThe Eastern Suburbs is one of the most rewarding and most constrained places in Sydney to build. These are the local factors that shape cost, design and programme here.
Randwick, Waverley and Woollahra each list heritage items and heritage conservation areas in their local environmental plans. A property in one usually needs a development application, a heritage impact statement and a design that respects the streetscape. We bring heritage consultants in at concept stage, not after council writes back.
Each council sets its own development control plan for setbacks, height, privacy, landscaping and parking. The Randwick, Waverley and Woollahra DCPs differ on the details, and those details decide what an extension or new home can look like. We read the controls for your lot at feasibility.
Narrow streets, terraces with shared walls and limited parking are normal here. We plan access, deliveries and crane or scaffold positions early, and record the condition of neighbouring properties before work starts.
Salt air from Coogee to Bondi is hard on concrete, steel and coatings. In apartment buildings it shows up as concrete cancer, failed balcony membranes and corroded balustrades, which is why so much of our Eastern Suburbs work is remedial.
Much of the area is apartments. Renovations need strata approval under the building by-laws, and work that touches waterproofing, structure or fire separation in a Class 2 building needs a registered building practitioner. Shafbuild holds that registration.
We work right across the Eastern Suburbs, and across greater Sydney for the right project.
Council by council: builders in Randwick, Bondi and Waverley, Woollahra, Double Bay and Vaucluse, the City of Sydney and Bayside.

Substantial commencement works that kept an approved development from lapsing, scoped, built and certified in two weeks.


Great remedial builders in eastern suburbs their communication was excellent. The quality of problem solving & advice was we received really helped us understand the project better, plus the way they broke down how the process would work


My partner and I had a fantastic and quality experience with our home renovation. After meeting Dan we trusted the process from the very beginning. Thanks Shafbuild for making the renovation process seamless!


Great builder who communicated every step of the way. Received regular updates and felt we could trust Dan and the team with our plans. Highly recomend.
Costs here are shaped by heritage controls, tight access, older building stock and the finish level owners expect. Rather than quote a headline figure, we visit the site, read the planning controls for your lot and give you a fixed, itemised scope with any provisional sums flagged upfront.
A complying development certificate (CDC) is usually the fastest pathway where your project qualifies. A development application (DA) carries a typical 10 to 16 week assessment risk, and can run longer in councils such as Woollahra where heritage and tree controls add complexity. We set the pathway at feasibility so your programme is realistic from day one.
It depends on the lot and the work. Properties that are heritage items or sit in a heritage conservation area, and work that doesn’t meet the state codes, need a DA. We check this in the first site visit.
Yes. We renovate apartments under strata by-laws and deliver remedial, waterproofing, concrete repair and facade works for owners corporations as a registered Class 2 building practitioner.
Our office is at 49 Boronia St, Kensington NSW 2033, so most Eastern Suburbs sites are a short drive away and the director is on site regularly.
