Decking and the rules on a residential park
Site rules and the site licence
Two sets of rules apply. The park's site rules, which the park owner has to consult residents on and deposit with the council, usually say what you may build and how to ask. The council's site licence conditions, based on the national model standards, set the separation distances between homes and what can go in them. Your installer should know both, but the written consent from the park has to come from you.
Where the deck can go
With a 6 metre separation required between homes, the safe places for decking are the front elevation and the side that faces your own garden or a road. Decking that intrudes into the gap towards a neighbour is the usual reason parks refuse consent. The model standards allow some structures within the gap if they are non-combustible, which is another reason to specify fire-rated uPVC or composite rather than timber.
Ramps and rails
A ramp needs more length than most people expect: a 450 mm rise at a comfortable 1 in 15 gradient is nearly 7 metres of ramp, usually with a turn and a landing. Handrails on both sides, a kerb along the edge and a non-slip surface make it safe in winter. Installers who work on residential parks build dozens of these a year.
Council tax, insurance and resale
Decking does not change the council tax band of a park home. Tell your insurer, as some policies list outbuildings and structures separately. When you sell, the deck normally goes with the home, and a well-built one helps; the buyer's survey will note a rotten timber deck as a cost.
