Boundary walls have been a feature of gardens since the early days of enclosures, and walled gardens became a common feature on large estates. Nowadays, however, large boundary walls are uncommon, having been replaced by cheaper fences or hedges.

Although walling may be the most expensive kind of boundary, it is immensely long-lasting, and can form an attractive, robust perimeter to any garden. There is a wide range of materials from which to choose, from natural stone to patterned concrete. The majority of garden walls are free-standing, but retaining walls, which support a bank or higher level, can also become an integral and highly practical part of the garden framework.

As well as being immensely practical, garden walls are often also decorative, and low walls are especially effective when planting cavities are used within them. Low walls require less substantial foundations and supporting piers, which also means they are easy and cheap to construct.

In this section, we have some handy tips and advice on choosing the right materials, how to make a concrete footing for your wall, building your wall, as well as information on dry stone and retaining walls.
