Project completion in Oxford! This bright and airy extension replaced a glazed conservatory that couldn’t be used throughout the year. Our client was keen to create a better connection to the garden whilst maintaining good levels of natural daylight. The offset window mullion provides a square picture view of the garden from the kitchen sink, while the flat rooflight above floods the space with quality ambient light, ensuring the central part of the house avoids darkness.

Our client had deeper retrofit ambitions, including external wall insulation and replacement windows. These ambitions were limited by the budget, so a staged approach was adopted. Given that the existing floor boards and joists showed signs of rot, it made sense to remove the floor boards, repair and treat the joists, and insulate and make airtight the ground floor. This also afforded the opportunity to install a new bamboo floor finish to create a warm, robust, and natural finish.
