About Barbalace

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.

What We Do

Services

High-end residential construction, managed by a builder who's been doing it since 1980.

01

Extensions

Ground-floor and second-storey extensions that add real living space, built to match your home's existing character.

02

Alterations & Additions

Structural changes and additions that reshape how your home works, from reconfigured floor plans to full reworks.

03

Duplex Builds

End-to-end duplex construction for owners and investors, managed from approvals through to final handover.

04

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 Warranty
05

Design & Documentation

3D renderings and CAD drawings prepared once your contract is signed, so you see the exact result before a single wall comes down.

The Difference

Why Barbalace

We don't chase the cheapest quote — we build for clients who want it done properly, once.

01

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.

02

10-Year Structural Warranty

Structural work on bathroom renovations is backed by a decade-long warranty; cosmetic finishes carry the standard 2-year cover.

03

High-End Standard

We work to a quality benchmark, not a discount one — built for clients who value the finish.

04

45+ Years on the Tools

Decades of hands-on building experience now channelled into tightly managed projects.

How It Works

Our Process

A clear path from first call to finished build.

01

Phone Consultation

We start with a call to understand your project, timeline and budget.

02

In-Home Assessment

Joseph or Lorenzo visits your property to assess the scope and take measurements.

03

Fixed Quote

A clear, fixed-price quote based on your in-home assessment, so you know the full cost before deciding to proceed.

04

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.

Service Area

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.

Who We Build For
  • 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.
