Decking on Sloping Sites


The examples below are all decks which were built on sloping sites.

In actual fact, I have never yet found a site which doesn’t slope to some degree. However, what I am trying to do here is describe how I have built decks on sites which have a significant slope to them. This is a situation to which decking is ideally suited, as it is a reasonably easy way to provide a usable flat surface for seating etc.

This is a small deck situated in West Haddon. It is just over 20 square metres, built on a site, which sloped in two directions. The handrail was already in place and the deck was built around this.     […]


Even a gently sloping site can be a problem for home owners who want a space to put a table and chairs. Decking is ideally suited to this situation because it makes it fairly easy to provide such a flat surface. The alternative would be a “hard landscaping” approach. The site would have to leveled  by either excavating the high points  or raising the low points. In either case retaining walls would have to be built to hold back the soil or back fill. These walls would of course need substantial footings which would need more excavating.

Decks built on a sloping site, needs no such excavating except for a few holes for the support posts. There are of course, some potential disadvantages to consider. Mostly these are due to the extra height which can mean that suddenly, it is easy to see into your neighbour’s garden (on the other hand it makes it easy to chat to them if you get on well). However, hopefully, the above examples have shown that this can sometimes be overcome by making the deck split level. This again, is much easier to achieve with decking than with other forms  of hard landscaping. Also of course, having a raised deck on a sloping site can improve the view if you have an open outlook.
