Site visits are available across Hythe (SO45). Neighbouring towns we cover include Southampton (3 miles), Totton (6 miles), Eastleigh (8 miles), Fareham (10 miles).
Just over the Isle of Wight border, Cowes is about 8 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.

Planning and approvals in Hythe
In England a single-storey extension to a bungalow follows the normal permitted development limits (3 m or 4 m, or 6 m and 8 m through prior approval). Adding a first floor always needs planning permission.
The planning position for a specific Hythe address depends on its history and any designations, which is why we check it at the first visit.
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).
