Renovating Victorian cottages in Sydney’s inner-city comes with unique challenges—limited parking, tight spaces, close neighbors, and strict council regulations. Keeping the site safe, clean, and efficient is a top priority, especially when working indoors in confined areas.

To streamline the process, we prefabricate major building components in our workshops, reducing on-site construction time, minimising disruptions, and controlling costs. We also prefer concrete and steel over timber framing, ensuring superior strength, durability, and long-term value for your home.

This approach allows us to deliver high-quality results with minimal hassle, so you can enjoy your renovated home sooner.

🏡 Home Extensions & Additions – More space, better ventilation, more value.
🔨 Inner-City Renovations – Modern upgrades with minimal disruption to you and your neighbours.
🏗 Structural Upgrades – Solid, engineer-design concrete and steel materials that last.
📐 Cost-effective Design & Build  – Based on your design brief, we will select suitable materials and build to a cost.
