uPVC Bay Windows Sydney
An angled multi-panel configuration that projects beyond the wall line, adding usable floor space and a wide outlook to the room behind it.
A bay is not a single window but a set of them joined at angles and cantilevered or supported beyond the wall line. The result adds a metre or so of floor area, a window seat if you want one, and a viewing angle far wider than a flat window in the same wall could give. They are common on Federation and interwar Sydney homes and are one of the details that make those houses worth keeping.
Replacing a heritage bay
Most bays we replace are original timber that has swelled, dropped or rotted at the sill, or aluminium retrofitted in the seventies that never suited the house. Because our frames are made to measure we can reproduce the original sightlines, panel proportions and angles in uPVC, in a woodgrain finish if the streetscape or a heritage control calls for it, while the thermal performance moves forward by fifty years.
How the panels are configured
A typical bay puts a large fixed pane in the centre for the view, with casements or awnings on the angled returns for airflow. That mix keeps cost down and sightlines clean. Three-panel and five-panel bays are both standard, and the angles are set to your existing opening.
Structure and install
A bay carries load differently to a flat window and the head detail matters. Our own installers handle the structural set-out, the flashing and the internal and external trims, and remove the old frame entirely rather than fitting over it.

Casement Windows
Side-hinged so the sash swings clear of the opening, a casement gives you the whole aperture for airflow and an uninterrupted view when open.
From $580
Tilt and Turn Windows
The signature European window: one handle, two modes. Tilt the sash inward at the top for secure background ventilation, or turn it a further ninety degrees to swing fully open.
From $780
Awning Windows
Top-hinged so the open sash forms a small awning over the opening - which is exactly why they can stay open through a Sydney downpour.
From $520
Sliding Windows
Horizontal operation within the frame, so nothing swings into the room or out over a walkway. The practical choice where space rules out a casement.
Fixed Windows
No sash, no hardware, no gap to seal - which makes a fixed window the best thermal and acoustic performer in the whole range, and the cheapest per square metre.
From $350
