College Lawn is a rear extension to an existing home that showcases open corner sliding doors in Cheltenham, supplied and installed by IQ Glass. The new ground-floor glazed room opens the original house onto the garden, combining large ultra-slim sliding doors, conservation-style rooflights and frameless roof glazing to create a bright, contemporary living space finished in RAL 7016 that sits comfortably against the existing property.

The heart of the extension is a pair of ultra-slim three-track sliding doors that meet at an open corner. When the doors are stacked back, the corner clears completely, removing any post from the view and opening the room directly onto the terrace. Flush thresholds and an integrated slot drain maintain level internal floors while quietly managing surface water. Solar control glass helps control summer gains without sacrificing the clarity of these open corner sliding doors in Cheltenham.
Above, a roof glazing package was developed to bring balanced daylight into the depth of the plan. A long Sieger Legacy conservation rooflight references traditional rooflight proportions while delivering modern performance, sitting alongside a frameless fixed roof pane that emphasises the clean lines of the extension. An ARES automated opening rooflight with opaque glazing provides controlled ventilation and privacy, opening for purge ventilation at the touch of a button and closing securely when not in use.
Performance and durability were built into the specification. The large sliding panes were heat soak tested to reduce the risk of spontaneous breakage on this highly glazed corner, and the external aluminium framing was finished in RAL 7016 for a coherent, low-maintenance exterior. Slot drainage, perimeter flashings and pressings were coordinated to keep the glazing as minimal as possible while protecting the building fabric.
The completed rear extension is a clear example of how open corner sliding doors in Cheltenham can transform a ground floor, delivering seamless garden connections, generous natural light and a calm, modern interior.
