The extension in Winchfield involved the replacement and modernisation of two large timber framed windows to the rear of the property, with new frameless glazed panels. The existing ground floor sliding timber framed screen was replaced with a fixed glazed pane, and the first floor protruding bay window was demolished so the replacement glazing was flush with the external wall, similar to the ground floor intervention. These two full height panes of glass had concealed frames and zinc cladding between them, to further perpetuate the contemporary nature of these changes.

Alongside this, the internal arrangement of the adjacent spaces were reconfigured to better align with the idea of modern living. Internal walls were removed to create open plan layouts on both the ground and first floors, allowing for these larger spaces to benefit from the addition of the new glazed systems. This alteration was particularly beneficial on the ground floor, as the views provided by the new glazing were now available from the kitchen, dining area, and living area.
