Side extensions · Berkshire
Side extensions in Windsor.
A side extension in Windsor reclaims the dead space down the flank of the house and keeps it proportional to the original. We design it, then carry it through Royal Borough of Windsor and Maidenhead to a construction-ready package.

Do I need planning permission for a side extension in Windsor?
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. Royal Borough of Windsor and Maidenhead is the authority that decides any application or issues a lawful development certificate for Windsor. 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 Royal Borough of Windsor and Maidenhead. 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?
