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 five 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.

10 Hollybush Road Cyncoed Cardiff CF23 6TA
Our preference would be to remove the Yew Tree (TPO map ref:T3) and replace with a new Common Yew Tree, or another of the Tree Officer's specification. If permitted, the new tree would be planted in the North West corner of the property, inside the front wall and 2-3m from the westerly edge of the property. If it is not possible to remove and plant a new tree, we would like permission to reduce the crown by approximately 25% to free up overhead phone cable (as was previously approved in 2018 - application CYNC/TP/18/00159) and shape to be aesthetically pleasing.
