Extension

The client brief called for the creation of a large new extension in place of an existing 1990 porch and utility wing, replacing it with a consolidated space containing a new dining room, sunroom, porch, vestibule, pantry, laundry and boot room - all within the sensitive context of a historic 18th century house.

To minimise its carbon footprint the project includes an airtight, thermal-bridge free envelope, triple glazed floor-to-ceiling glazing, a ground source heat pump, solar PV array as well as a mechanical ventilation and heat recovery system (MVHR).

Natural and non-toxic materials were used throughout where possible, including clay blocks, lime plaster, wood fibre insulation, timber and reclaimed brick.

Key to the extension design was the need to create a new prominent main entrance on the side of the house, after the original central approach lost its function when neighbouring land was developed for housing in the 1990s. This was achieved by positioning the entrance at a 45 degree angle to the rest of the building, facing the current access to the site.
