Two-storey extensions · Brighton & Hove
Two-storey extensions in Brighton.
A two-storey extension in Brighton 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, take it through Brighton & Hove City Council, then build it.

How the path runs in Brighton
The Plan Hub takes two-storey extension work in Brighton from first idea to a finished room. Brief, measured survey, design, planning, then the build itself, in order, held by one team that owns the thread.
Brighton & Hove City Council is the authority that decides any application in Brighton. We prepare the drawings and manage that submission. Once it is approved, our own team builds it.
Common questions
Do I need planning permission for a two-storey extension in Brighton?
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. Brighton & Hove City Council is the authority that decides any application or issues a lawful development certificate for Brighton. 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 Brighton & Hove City Council. One team holds the thread through each step, so nothing is dropped between people. Once it is approved, that same team builds it.
Does The Plan Hub build the two-storey extension as well?
Yes. We design the work, take it through planning, then build it. The same team that drew your two-storey extension manages the trades and runs the site in Brighton through to completion. If you would rather take the drawings to a builder of your own, you can. The choice stays yours.
