Do I need planning permission in Isle of Wight?
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
Covering Isle of Wight
Towns we cover in Isle of Wight include Newport, Isle of Wight, Ryde, Cowes, Sandown. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
