Four decades of building,
done right
Barbalace Construction has been building in Sydney since 1980 — a family business founded by Antonio Barbalace and now led by Joseph Barbalace, based in Kingsgrove. For over 45 years the focus has stayed the same: quality execution, honest communication, and a finish clients are proud of.
Joseph's son Lorenzo now works alongside him as the business shifts from direct tradework to hands-on project management — giving every job the same close attention to detail, with tighter control over quality, timelines and trades on site.
Services
High-end residential construction, managed by a builder who's been doing it since 1980.
Extensions
Ground-floor and second-storey extensions that add real living space, built to match your home's existing character.
Alterations & Additions
Structural changes and additions that reshape how your home works, from reconfigured floor plans to full reworks.
Duplex Builds
End-to-end duplex construction for owners and investors, managed from approvals through to final handover.
Bathroom Renovations
Full bathroom renovations finished to a high standard — structural work backed by a 10-year warranty, with cosmetic finishes covered for the standard 2 years.
10-Year Structural WarrantyDesign & Documentation
3D renderings and CAD drawings prepared once your contract is signed, so you see the exact result before a single wall comes down.
Why Barbalace
We don't chase the cheapest quote — we build for clients who want it done properly, once.
3D Renderings & CAD
Once your contract is signed, every project is drawn up in full before it's built, so you know exactly what you're getting.
10-Year Structural Warranty
Structural work on bathroom renovations is backed by a decade-long warranty; cosmetic finishes carry the standard 2-year cover.
High-End Standard
We work to a quality benchmark, not a discount one — built for clients who value the finish.
45+ Years on the Tools
Decades of hands-on building experience now channelled into tightly managed projects.
Our Process
A clear path from first call to finished build.
Phone Consultation
We start with a call to understand your project, timeline and budget.
In-Home Assessment
Joseph or Lorenzo visits your property to assess the scope and take measurements.
Fixed Quote
A clear, fixed-price quote based on your in-home assessment, so you know the full cost before deciding to proceed.
Managed Build
Once your contract is signed, we prepare your 3D renderings and CAD drawings, then manage the project start to finish with one point of contact.
Sydney
We work with homeowners across Greater Sydney, within roughly a 40km radius of Kingsgrove. If you're outside that range, let us know and we'll point you in the right direction.
- Homeowners planning a genuine renovation, extension or new build — not a quick patch-up job.
- Committed timelines — projects ready to move within a 30–60 day window.
- Owners or landlords with consent to renovate, so we can start without delay.
- Quality-first clients who want it built properly the first time, not the cheapest price.
