What refusal means

The process from here

The council refused this application for the reasons set out on the decision notice, which the council portal holds in full. Only the applicant can appeal a refusal; the time limit runs from the decision date and is shorter for householder schemes.

Refusal does not prevent a fresh attempt. Applicants often address the reasons for refusal and resubmit, so a refused scheme is not necessarily the end of proposals for the site.

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.

  • P2025/1075/TRE Awaiting decision

    94 Hornsey Lane, London

    This application concerns a common lime tree which sits on land within the garden of 94 Hornsey Lane, immediately adjoining the lane leading to 10 garages and 77 Whitehall Park, N19 3TW. The tree is leaning into the lane, and causing an obstruction to lane traffic - and the angle at which it is leaning is speeding up, which makes us think it could be dangerous. The tree can be seen in the accompanying photos. It is one of a group of self-seeded trees which have been allowed to grow in an uncontrolled manner. Our plan is to remove that part of the tree which obstructs the lane, leaving the trunk of the tree (in the neighbour's garden). The neighbour has not responded to numerous requests to deal with this tree - and latterly to permit us to remove it completely at our sole expense. He has been contacted by email, registered letter and text.
