Towns in Forth Valley
Planning and approvals in Forth Valley
In Scotland a small porch can be permitted development (Class 1C) within limits on floor area, height and distance from a road; larger porches need planning permission, and building standards still apply, so we check whether a building warrant is needed.
Homes in conservation areas, national scenic areas and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.
