A draughtsperson or architectural technician can prepare any drawings needed. A full architect may not be necessary.
Garden buildings and garages can often use supplier designs or simple drawings from a draughtsperson.
Typical fee: £500–£2,000 (Basic drawings)

The same Class E rules apply in conservation areas. Total outbuilding coverage must not exceed 50% of the curtilage area.
Properties in conservation areas often have reduced permitted development rights. Some project types (like side extensions) lose PD rights entirely. An Article 4 Direction can remove additional PD rights.
Listed buildings (Grade I, II*, or II) have no permitted development rights at all. Any external alteration requires Listed Building Consent in addition to any planning permission. An architect experienced in heritage work is essential.
Check if your property is in a conservation area or has other planning constraints.
