   Awaiting decision

   Decision expected by 13 October 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Richmond upon Thames took a median of 45 days over the applications it decided in the last year.

This application is with Richmond upon Thames for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.

The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.

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.

  5 DAY DANGEROUS TREE NOTICE The main limb has fallen into client's property which has now been cleared. Consequently, there is a large open wound, and the 3 remaining limbs are all leaning over into 2 neighboring gardens behind. The tree is on the lean anyway and I believe it needs to be removed immediately preventing any damage to people or property. Client is very keen to re-plant.
