Decking in London

London gardens are mostly small, overlooked and often shared, so a deck that keeps to 300 mm and sits in the back half of the plot avoids both planning and neighbour trouble. Flats and maisonettes have no permitted development rights at all; conservation areas cover much of the inner boroughs.

Planning: your borough council

In England a deck is permitted development when its platform is no more than 300 mm above the ground, it is not in front of the main elevation, and outbuildings and decks together cover no more than half the garden. Listed buildings, flats, and homes under an Article 4 direction need checking with the council.
