Do I need Planning Permission or can it be done under Permitted Development?

Answer

There are requirements for permitted development:

• Volume allowance: 40 cubic meters for terraced, 50 for semi & detached houses.
• No extension beyond the front roof slope (road side).
• No extension that is constructed higher than the existing ridge line.
• External finish to match existing look and materials used on property as new as possible.
• No raised platforms, balconies or verandas.
• Gable end/side facing windows to be obscure and any part which is opening must be 1.7m above loft floor.
• Not in a conservation area.
• Dormer to be sat back in from roof edge as far as practicable but at least 20cm from the fascia board.

If your property/loft design does not fall into permitted development we can arrange planning permission applications for your loft conversion.
