Side extensions · Buckinghamshire
Side extensions in Marlow.
A side extension in Marlow reclaims the dead space down the flank of the house and keeps it proportional to the original. We design it, carry it through Buckinghamshire Council, then build it.

Common questions
Do I need planning permission for a side extension in Marlow?
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. Buckinghamshire Council is the authority that decides any application or issues a lawful development certificate for Marlow. 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 Buckinghamshire 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 side extension as well?
Yes. We design the work, take it through planning, then build it. The same team that drew your side extension manages the trades and runs the site in Marlow through to completion. If you would rather take the drawings to a builder of your own, you can. The choice stays yours.
