Common questions
Do I need planning permission for a side extension in Sutton?
Some side 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. London Borough of Sutton is the authority that decides any application or issues a lawful development certificate for Sutton. We prepare the drawings and manage that submission for you.
What does the design and planning stage involve for a side extension?
It runs in order: brief, a measured survey of the house, design, then the planning submission to London Borough of Sutton. 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 side extension as well?
No. The Plan Hub takes the work through design and planning to a construction-ready handover. Your chosen builder carries out the construction in Sutton. Our job stops where theirs begins.
