Rules & regulations
- Permitted development if the deck is under 30cm high and, with other outbuildings, covers less than half the garden
- Raised decks overlooking neighbours can need planning permission
Snap tips
- The frame is the investment, premium boards on a soft frame still fail
- Composite costs nearly double up front and wins it back in zero maintenance
