Questions about architecture
The things clients usually ask us first.
Many single-storey rear extensions fall under permitted development, but conservation areas and listed buildings change that. We check during the first visit.
Householder applications are determined within eight weeks. Larger or contentious schemes can take longer; we budget for that in the programme.
We coordinate with a party wall surveyor and provide the drawings they need, so notices go out in good time.
