Decking in Cardiff

Cardiff's gardens in Roath, Canton and Whitchurch are mostly level, with heavy clay and high rainfall. Welsh permitted development rules differ from England's in the detail, so a raised deck needs checking against Wales's order, not England's.

Planning: Cardiff Council

In Wales a deck is permitted development when its platform is no more than 300 mm above the ground, it stays behind the main elevation, and outbuildings and decks together cover no more than half the garden. Flats, listed buildings and Article 4 areas need checking with the council.
