0. Introduction

This Design, Access and Heritage Statement is submitted in support of the planning application for the proposed refurbishment works to the vault to the front of No. 28 Gibson Square, London.

In drawing up this proposal we have analysed and responded to relevant national and local planning policy in addition to the site’s unique built and historical context. We feel the resulting design to the vaults of a Grade II listed is appropriate and sensitive to its surroundings within the Barnsbury Conservation Area location.
