   Received by Hounslow

   Decision issued: REFUSED

3. 12 Aug 2026

   Added to PlanIndex

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.

A full application seeks permission for a complete, detailed proposal in one go: siting, design, access and landscaping are all fixed at this stage. It is the standard route for new buildings, conversions and changes of use. The statutory target is eight weeks for smaller schemes and thirteen weeks for major development, though complex cases often take longer by agreement.

  Non-material amendment for Prior Approval ref 00590/3-8/PA2 and Planning Permission ref 00590/3-8/5 were conditional upon the submission and approval of a Car Park Management Plan. The CPMP dated 18/10/19, which was subsequently approved, detailed the strategy in regards to electric vehicle parking and specifically, the approach to provision of active and passive charging facilities. With this submission of an updated CPMP, we are seeking to amend the approach to future upgrades of passive parking spaces. This process this was previously to be facilitated and funded by the applicant, however the development is now controlled by a management company who will be responsible for actioning any future upgrade requests and with the cost to be borne by the resident (as is industry norm).
