Common questions
Do I need planning permission for a house extension in Watford?
Some house 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. Watford Borough Council is the authority that decides any application or issues a lawful development certificate for Watford. We prepare the drawings and manage that submission for you.
What does the design and planning stage involve for a house extension?
It runs in order: brief, a measured survey of the house, design, then the planning submission to Watford Borough 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 house 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 Watford. Our job stops where theirs begins.
