Custom Homes

Elevated Homes, Thoughtfully Built.

A custom home is more than bricks and mortar – it’s your lifestyle made tangible.
At Locspec Building, we specialise in creating tailored homes for families across Kiama, Wollongong, the South Coast, and Illawarra who value quality, comfort, and smart design. 

We are proud to be leading the way as a high-performance custom home builder in our region, and strive to always source sustainable and high quality materials. We work closely with you and your designer to craft a home that’s perfectly matched to your block, your stage of life, and your future needs.

At Locspec, we believe the best builds come from collaboration and care. From early-stage concept reviews to the final handover, our team provides transparency, creative problem-solving, and expert trade coordination every step of the way.

Our ongoing training, eye for detail, and hands-on approach ensure your project is executed to the highest standards. Measurements are carefully checked, outcomes are discussed to avoid rework, and the end result is a home you can enjoy for decades to come.

What is a High-Performance home?

A high-performance home isn’t an everyday house – it’s a considered decision for those who value exceptional living. Designed with purpose and built with precision, these homes combine beautiful architecture with intelligent, sustainable design. They’re not built to last 20 years – they’re built to last 50, with every detail planned to stand up to Australia’s increasingly severe weather patterns.

Every element works together – from airtight construction and thermal control to smart ventilation and natural light – creating a home that feels calm, consistent, and comfortable in every season. With dramatically reduced energy use and a lighter environmental footprint, a high-performance home is a commitment to healthier living today and a more sustainable future for generations to come.

Some key benefits of a high-performance home:

Superior Energy Efficiency
  • Designed to minimise heating and cooling demand through insulation, air-tightness, and passive solar design.
  • The use of advanced glazing such as thermally broken or UPVC windows.
  • Controlled ventilation systems (e.g., HRV – Heat Recovery Ventilation) for fresh, filtered air.
  • Low-VOC finishes and materials to reduce pollutants.
  • Vapour-permeable building wraps (like Pro Clima products) to prevent condensation and mould.
  • Even temperatures year-round without draughts or hot/cold spots.
  • Acoustic control for a quieter indoor environment.
  • Built with robust materials and detailing to reduce maintenance and extend the life of the home.
  • Cavity battens create airflow and drainage behind cladding, protecting your home for the long term.
  • Reduced reliance on heating/cooling means lower energy bills.
  • Integration of renewable energy systems like solar PV and battery storage.

If you’re ready to create a home that reflects your lifestyle and values, we’d love to hear your vision.
