What goes into a static caravan deck
Boards
Most new decks on parks are uPVC: hollow plastic boards in a timber-grain finish that never need painting, do not rot and come with a fire rating the park can accept. Composite boards (wood fibre and plastic) look closer to timber and cost about the same. Treated softwood is cheapest on the day, but it needs re-treating every year or two, it holds water on a shaded pitch, and a growing number of parks will not allow a new timber deck at all because of the fire risk. Ask the park before you fall in love with a material.
Subframe and feet
Because the deck sits on a pitch rather than in a garden, it is built on adjustable feet or concrete pads with no digging. A galvanised steel or aluminium frame costs more than timber joists but will outlast the caravan. The frame is levelled from the caravan floor so the deck meets the door threshold without a step.
Balustrade, gates and steps
Balustrades are normally 1,100 mm high with spindles no more than 100 mm apart, in white, cream, grey or anthracite to match the van. Steps come with a handrail, and a self-closing gate at the top of the steps is worth having if grandchildren visit. Glass panels in place of spindles add a few hundred pounds a run and are popular on sea-view pitches.
Lighting, skirting and the finishing touches
Low-voltage post-cap or recessed deck lights, a matching uPVC skirt around the base of the caravan, and a storage gate under the deck are the usual extras. Parks often require the void under the deck to stay open or vented, so check before you plan to store gas bottles or furniture there.
