Common questions
Do I need planning permission for a multi-storey extension in St Albans?
Some multi-storey extension work falls under permitted development, but limits on size, height and materials apply, and they are tighter in conservation areas and on Green Belt land. St Albans City and District Council is the authority that decides any application or issues a lawful development certificate for St Albans. We prepare the drawings and manage that submission for you.
What does the design and planning stage involve for a multi-storey extension?
It runs in order: brief, a measured survey of the house, design, then the planning submission to St Albans City and District Council. One team holds the thread through each step, so nothing is dropped between people. You receive a contractor-ready package at the end.
Does The Plan Hub build the multi-storey extension as well?
