QUALITY YOU CAN SEE

Light, Space & Structure

Aluminium doors and windows play a major role in how a home looks, feels and functions. Lennox Build supplies and installs aluminium doors and windows in the Northern Rivers, delivering clean lines, durability and low-maintenance finishes suited to new builds and renovations.


From sliding and stacking doors to fixed, awning and sliding windows, aluminium framing offers strength without bulk. It allows for larger openings, improved natural light and consistent detailing across the facade. Slim profiles maximise glass area while maintaining structural integrity, making them well-suited to contemporary homes and extensions. Every unit is measured, supplied and installed to suit the home’s layout, orientation and overall design.
