Two-storey extensions in Hitchin.
A two-storey extension in Hitchin adds room above as well as below, so the design has to settle both floors and the elevation at once. We draw it as one move and take it through North Hertfordshire Council.

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