What a grant of permission means
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 householder applications
How this application type works
Householder applications cover work to an existing house and its garden: extensions, loft and garage conversions, porches, outbuildings and similar alterations within the boundary of the home. They cannot be used to create a separate dwelling or change what the building is used for. Councils aim to decide them within eight weeks, and immediate neighbours are usually notified and given a chance to comment.

We wish the condition to be removed, because the results of further site investigations support our original proposal to raise the coal vault door opening height. As part of clearing other conditions for the Listed Building consent, a site investigation has been carried out of the coal vault entrance door lintel. It was revealed that there is no existing historic brick arch above the entrance, as would be expected if it was original, and instead a concrete lintel was found. Please refer to Chelmer Global Ltd Factual report: 'FACT14165 (rev1).pdf' page.3 'Sketch Site Plan' and page.14 'Photograph 5 - Opening Up 1 (OP1)'. The existing lintel to this internal coal vault is positioned lower down from the vaulted arch ceiling behind, than the higher positioned lintel to the external coal vault. Please refer to existing drawing GB-SA-DR-A-3010-2001 view: 'East Front Lightwell' and GB-SA-DR-A-3010-2001. We propose that the entrance opening height to be raised by 100mm by replacing the concrete lintel in accordance with the structural engineer's design, method and specification. Please refer to detail drawing GB-SA-DR-A-4030-5002, and structural engineer's documents: '4350.02 - Design Intent Report.pdf' and '4350 - Specification.pdf'. This change to the internal coal vault opening would bring it in line with external coal vault opening and the head would remain below the vaulted ceiling behind. Please refer to proposed drawings GB-SA-DR-A-4030-3003 view: 'East Front Lightwell' and GB-SA-DR-A-4030-2001. The proposed height of the door opening would be 1.7m, which will remain clearly subordinate to the height of the main doors of house and not alter the vault's historic characteristically low entrance height. Please refer to other drawings updated accordingly: GB-SA-DR-A-3010-1209 - PLAN LOWER GROUND LEVEL EXISTING GB-SA-DR-A-3010-1210 - PLAN GROUND LEVEL EXISTING GB-SA-DR-A-3010-2001 - ELEVATION WEST EXISTING GB-SA-DR-A-3010-3001 - SECTIONS 1 EXISTING GB-SA-DR-A-3010-3002 - SECTION 2 EXISTING GB-SA-DR-A-3010-3003 - SECTION 3-4-5-6 EXISTING GB-SA-DR-A-4030-1009 - PLAN LOWER GROUND LEVEL PROPOSED GB-SA-DR-A-4030-1010 - PLAN GROUND LEVEL PROPOSED GB-SA-DR-A-4030-2001 - ELEVATION WEST PROPOSED GB-SA-DR-A-4030-3001 - SECTION 1 PROPOSED GB-SA-DR-A-4030-3002 - SECTION 2 PROPOSED GB-SA-DR-A-4030-3003 - SECTION 3-4-5-6 PROPOSED GB-SA-DR-A-4030-5002 - SECTION DOOR HEAD CONSTRUCTION EXISTING & PROPOSED Further photos of door opening lintel: 46GS_SI_CVbefore.jpg 46GS_SI_CVhole2.jpg 46GS_SI_CVhole3.jpg 46GS_SI_CVholeunder1.jpg
