Solihull Metropolitan Borough Council is the local planning authority. It is a metropolitan borough and therefore unitary, so planning, building control and the roads all sit with the same authority. There are 20 conservation areas in the borough.
The Olton Article 4 direction
This is the one to know about, and it is unusually broad. On 30 May 2019 the council authorised an Article 4 Direction removing residential permitted development rights from properties within part of the Olton Conservation Area, with the aim of encouraging alterations that preserve or enhance the area’s historic character. The effect is that planning permission is now required for most householder development there.
Most Article 4 directions are narrow, covering houses in multiple occupation or a specific feature such as windows. This one is not. If your property falls within the affected part of Olton, the working assumption should be that an application is needed for work you would elsewhere simply get on with, and it is worth confirming that with the council before a designer is engaged.
Trees
Any tree in a conservation area over 75 millimetres in diameter, measured at 1.5 metres above ground, has automatic protection. No cutting, removal, damage or destruction is permitted without prior notification to the council. That threshold is small, which means a great deal more planting is protected than people assume. Wilful destruction of a protected tree without consent is a criminal offence carrying a maximum fine of £20,000.
Green Belt
Most of the undeveloped borough is Green Belt, where national policy presumes against inappropriate development. Extensions to existing dwellings can be acceptable but are tested against whether they are disproportionate to the original building, and outbuildings and annexes are looked at closely. We establish the Green Belt position before designing anything on a village or rural property.
Permitted development, where it survives, is still not an exemption from Building Regulations. A full plans application is required, and we arrange and meet the inspections that follow and see the work through to sign off.
