Listed Building Consent for Summer Annexe

We have just received Listed Building Consent to extend and alter an outbuilding in the grounds of a Georgian house in Chiswick, where we have just finished alterations to the main house including a double height glazed extension.
The summer annexe will now be renovated, insulated and extended with a glass-to-glass addition and stained timber clad storage shed. The architecture will reflect the glazing of the main house alterations, and is intended as a jewel hidden in the garden, surrounded by trees and foliage.
