Refurbishment and extension of a detached 1930s house, set within nine acres of woodland within an Area of Outstanding Natural Beauty in the Chilterns

On the ground floor, the entrance hall, family living room and study retain original features. A small hall extension creates a bay window seat in the language of the existing house.

The new living / dining extension to the north contrasts the existing architecture with a large open plan vaulted roof which sits on exposed glulam beams that were chosen as a contemporary reference to the exposed beams in the main house.

The external structure enables the corner of the room to be opened up to the woodland landscape beyond. Minimal glazing strengthens the contrast with the existing glazing and links the building to the landscape beyond.
