When do I need planning permission?

In any Conservation Area, special consideration is given to planning applications, and permission has to be obtained before a house can be demolished. The Oakmount Triangle also has Article 4 (2) protection, which means that permission needs to be sought for many minor works which would affect the public’s view of the houses. This only applies to the pre-1939 houses, and not to the fourteen post-1945 houses, which continue to have ’permitted development rights’, nor to the three blocks of flats, which have no ‘permitted development rights’ anyway.

Some benefits:

  • Although this means you may need to apply for planning permission for things that you may not need to in other areas, the good news is that residents in a conservation area do not need to pay the usual fee.
  • The character is preserved, and so the value of your property will not be reduced by the kind of large developments we have seen in Winn Road and Westwood Road.

General Guidelines

Disclaimer: this is purely for unofficial guidance. None of what we can tell you can be taken in any way as permission or authority to carry out works. OTRA cannot be held liable for any work you may carry out based solely on the information on this page. If in any doubt at all you can contact us for informal but non-legally binding advice, but for official advice and permisson contact Southampton City Council.

This can not be assumed to be a comprehensive list or entirely up-to-date and currently accurate. More detailed information about the features which give the triangle its character can be see in the Character Appraisal & Management Plan

Note that the permissions can apply to anything visible from a road, or public space so do not apply purely to the front of the building.

Like for Like?

* In most cases good like for like materials are still available. All good builders will be able to source either new or reclaimed (imperial size) bricks, tiles etc. When roofs need maintenance, roofers are usually able to carefully remove and replace most of the original tiles. Where a percentage of new tiles need to be used it is advisable to mix them in randomly or use at the back of the house, in order to avoid odd looking new patches.

If in any doubt about like for like materials please contct SCC planning or conservation department.
