This extension and refurbishment project is currently on site in Henley-on-Thames with a completion date later this summer. The main house volume is of a traditional red/brick finish with flush casement windows. However, in contrast to this, the single storey rear extension is defined as a separate volume in a handmade cream brick with herringbone panels. Taking advantage of this change in style for the single storey element, the kitchen and dining room have large openings into the garden via minimal aluminium sliding doors letting in large amounts of natural light. A sedum roof covers this flat roof extension, providing a much improved view over the flat roof as well as helping biodiversity and reducing rainwater run off.
