2025/4580 - Alter or Extend a Listed Building Approved

Proposal

Listed Building Consent is sought for a limited, conservation-led programme of investigative and enabling works to Diprose Chapel, a Grade II listed building forming part of the former St Clement Danes Holborn Estate Almshouses. The proposed works comprise opening-up, removal of later non-historic fabric, and localised investigation undertaken solely to understand the building???s construction, condition, and causes of deterioration, and to arrest ongoing decay. No new use, extension, alteration to external elevations, or permanent reconfiguration is proposed. The scope includes: Opening up of a blocked historic fireplace by removal of later infill materials only. Removal of non-historic suspended and plasterboard ceilings to permit inspection of roof structure and fabric. Removal of later twentieth-century partitions, linings, fittings, sanitaryware, and kitchen elements of no historic significance. Formation of small, localised floor test pits to inspect slab build-up and foundations. Localised opening-up around roof timbers and valleys to investigate areas affected by water ingress. Emergency stabilisation and like-for-like repair to roofs, valleys, and rainwater goods where required to prevent further deterioration. All works are reversible, investigative, and proportionate, confined to fabric of low or neutral significance, and do not involve the removal of any original historic fabric. The proposals will better reveal the significance of the listed building and establish a robust evidential baseline for future conservation. Data via plota.co.uk
