A key aim was to open up the space and bring in as much natural light as possible. The former extension was demolished and replaced with a larger, openly modern building to house an open-plan kitchen and dining area. Using 3D modelling software, we carried out sun studies to watch how the light fell across the building, morning to evening, summer to winter. The fenestration is designed to enhance this natural light and open up views across the large garden, incorporating a large corner aspect window and window seat. Predominantly glazed, the extension establishes a strong relationship between the inside and outside.
