Walthamstow E17
Your local extension builders in Walthamstow
Walthamstow is a residential area with rows of Victorian and Edwardian terraces, including the Walthamstow Village conservation area.
Whether you are planning a rear extension for a bigger kitchen-diner or a side return to widen a narrow kitchen, we survey your home, talk through the options and give you a clear, itemised quotation with a programme of works.
Planning applications in Walthamstow are handled by the London Borough of Waltham Forest. Many home extensions fall under permitted development, but if your home is in a conservation area those rights can be more limited, so we check this at the survey stage and can manage any application for you.
Our base at Ford End, near Chelmsford, is around 25 miles from Walthamstow, so it is well within the area we cover.

Do I need planning permission for an extension in Walthamstow?
