   The statutory target is eight weeks for most applications and thirteen for major development. Extensions of time are common.

This application is with Barnet 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.

A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.

• 26/2069/HSE Awaiting decision

  27 Fuller Street London NW4 4RR

  Single storey rear extension and repositioning of the external staircase The previous application was refused due to concerns relating to overlooking from the raised platform/terrace. The revised proposal has removed the platform in its entirety and retains only the external staircase to provide access to the rear garden. As a result, the overlooking concerns identified in the previous refusal have been addressed, and the proposal will not result in unacceptable impacts on the privacy or amenity of neighbouring properties.
