A Fully Openable Corner for Seamless Indoor–Outdoor Living
At 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 slid back, the corner clears entirely, removing any supporting post from the view and opening the room directly onto the terrace. This creates a dramatic, uninterrupted transition between the interior and the garden.
Flush thresholds maintain level flooring from inside to out, while an integrated slot drain manages surface water discreetly. Solar control glazing was specified to reduce summer heat gain without compromising the clarity and openness of the large glass elevations.
Daylight‑Driven Roof Glazing
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, Durability and Precision Engineering
The glazing specification was developed to ensure long‑term performance and reliability. The large sliding panes were heat‑soak tested to minimise the risk of spontaneous breakage on this highly glazed corner. All external aluminium framing was finished in RAL 7016 for a coherent, low‑maintenance exterior.
Slot drainage, perimeter flashings and bespoke pressings were coordinated to keep the glazing as minimal as possible while protecting the building fabric. Every detail was designed to enhance the architectural clarity of the extension.
A Contemporary, Light‑Filled Living Space
