Heritage Restorations
Bathroom/ Laundry Upgrades
Auburn is home to some beautiful pockets of older architecture that require a delicate touch. As an experienced heritage builder, Plexs respects the history of your property. We combine traditional lime mortars and timber fretwork restoration with discreet modern structural upgrades. Our goal is to preserve the soul of the home while ensuring it meets 21st-century standards for comfort and safety.
A premium bathroom is a sanctuary. Our bathroom renovators focus on high-end waterproofing, custom cabinetry, and intelligent lighting. We transform cramped, dated laundries and bathrooms into functional, spa-like spaces using porcelain large-format tiles, underfloor heating, and sleek, water-efficient fixtures that add immediate value to your property.

Kitchen Upgrades
The kitchen is the engine room of the Australian home. We design and install high-end kitchen renovations that focus on flow, storage, and social interaction. From stone-waterfall islands to integrated European appliances and butler’s pantries, our kitchens are built for those who love to cook and entertain.
Our reputation is built on full project management. This means you have a single point of contact overseeing licensed trades, site supervision, and strict quality assurance. We manage the scheduling coordination meticulously, ensuring that labour and material arrivals are timed to keep your project moving without unnecessary delays or budget blowouts.
Planning a Renovation or New Build?
Navigating the complexities of the NSW building industry in 2026 requires a strategic approach. One of the first hurdles for homeowners is deciding between a Development Application (DA) via council or Complying Development Certificate (CDC) through a private certifier. While CDC can be faster, DA is often necessary for heritage areas or complex designs near St Johns Road.
Budgeting and the Current Market:
Material Flux: While global supply chains have stabilised, premium timber and high-grade steel still fluctuate. We provide transparent, fixed-price contracts where possible to protect you from surprises.
Labour Shortages: Quality trades are in high demand. We maintain a consistent roster of trusted, licensed professionals, ensuring your site is never left dormant.
Future-Proofing: We recommend integrating EV charging points, solar-ready roofing, and greywater systems now to save on future retrofitting costs.
Building Quality You Can Rely On
At Plexs, "good enough" is never the standard. We pride ourselves on reliable workmanship and a meticulous attention to detail that is visible in every mitred tile and perfectly aligned skirting board. We use only premium-grade materials sourced from local Australian suppliers, ensuring your home is built to withstand the harsh Sydney climate. Our communication is proactive; you’ll receive regular updates on progress, milestones, and upcoming site visits, fostering a relationship built on total transparency.
Fully Licensed & Insured: Complete peace of mind with all NSW statutory warranties and insurances in place.
Local Council Experts: We know the Cumberland Council requirements inside out, speeding up the approval process.
Transparent Quoting: No hidden "provisional sums" that blow out your budget; just honest, detailed pricing.
Clean & Organised Sites: We treat your home with respect, maintaining a safe and tidy workspace throughout the build.
Tailored Solutions: We don't do "off-the-shelf." Every project is customised to your lifestyle and land.
Post-Construction Support: Our relationship doesn't end when we hand over the keys; we stand by our work.

FAQs
What is the average cost per square metre for a duplex in Auburn?
1
In the current 2026 market, high-quality duplex builds typically range from $2,500 to $3,800 per sqm, depending on the level of finishes and site complexity. Custom architectural designs may sit higher.
How long does a major home extension typically take?
2
Most significant extensions take between 6 to 10 months from slab to completion, though this varies based on weather and council approval timelines.
Does a kitchen renovation always increase property value?
3
Yes, a modern, high-functioning kitchen is widely considered the best return on investment for homeowners, often adding significantly more to the sale price than the cost of the renovation itself.
Can I live in my home during a renovation?
4
For smaller bathroom or kitchen upgrades, yes. However, for major structural extensions or second-storey additions, we usually recommend vacating for a portion of the build for safety and comfort.
What is the difference between DA and CDC?
5
CDC is a fast-track approval process for projects that meet universal NSW standards. DA is a more comprehensive merit-based assessment by the local council, required for more bespoke or heritage-sensitive designs.
We deliver licensed building expertise, architectural‑grade workmanship, transparent communication, and a smooth, well‑managed construction process. Our team is experienced with Sydney councils and committed to delivering high‑quality results that stand the test of time.
