Planning application
Diprose Lodge The Chapel 750 Garratt Lane SW17 0LY
Works: Extension
Permission granted. Work must normally begin within three years of the decision or the permission lapses.
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.

The process from here
Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.
Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.
About heritage and listed buildings applications
How this application type works
Heritage applications concern listed buildings and conservation areas. Listed building consent is needed for works, inside or out, that affect the special interest of a listed building, and carrying out such works without consent is a criminal offence. The council weighs harm to the heritage asset against any public benefit of the proposal.
