A pony wall is a half-height wall in a garden. The term dates to the days when it was necessary to build a barrier high enough to keep livestock from invading a formal garden without obstructing the view. Low walls were particularly popular with the Victorians who adopted ponies as cute pets (and didn’t require them to live in the stables with the bigger horses).
Today in garden design we use these pony walls as borders, low retaining walls, and backdrops as plantings. Pony walls also do double duty as built-in garden seating (they’re often the perfect height on which to perch).

How can a pony wall improve my garden?
When I design a landscape for a client, sometimes my first move is to divide the garden space into outdoor rooms. One way I create the feeling of different rooms or areas is to create varying elevations, with the help of low pony walls.
Insider’s Tip: Did you know that our eyes briefly (and unconsciously) refocus at vertical planes that come into view? Think of a camera’s auto focus. Because of this natural pause effect, a pony wall’s placement can subtly steer our focus and create or highlight focal points. Well-designed walls can also create raised garden beds or surround a fountain or fire pit.

What are the design guidelines for a pony wall?
When designing a pony wall to act as a bench, a comfortable height for an adult to sit is from 18 to 24 inches (including any capstones used). The best width that is safe and as comfortable as can be (you are sitting on a wall, after all) is a minimum of 12 inches wide.
For comfort, avoid capping a pony wall that will be used as seating with rough flagstone or other irregular surfacing that can jab, poke, or snag.
Insider’s Tip: A grinder can hone stone edges like magic, and bull-nosed cast concrete caps eliminates the problem all together.

What are the best materials to build a pony wall?
A solid choice for a pony wall is a cement block core with an ultra smooth stucco finish to resemble poured concrete. Why? Cinderblocks are 8 inches high, so two stacked will measure 16 inches; with a cap, you get to the desired 18 inches. Talk about perfect.
Other materials to consider are brick, stone or poured in place concrete. (See Hardscaping 101: Poured in Place Concrete for more tips.)
Ultimately, the best material is one that complements and speaks to the architecture of your home and the design of your existing garden. For example, if you have a natural stone patio, consider natural stone pony walls.
Insider’s Tip: Repeating hardscape materials in the garden is a proven way to unify a design and create a feeling of spacial cohesion.

What other design details for pony walls do I need to know?
If your walls will act as low retaining walls or planters, remember to incorporate adequate drainage behind them. For more information on this, see Hardscaping 101: Retaining Walls. Also consider adding lighting to the walls, such as down-lighting from recessed hidden fixtures built into the seat.

Do I need a permit to build a pony wall?
Construction of a pony wall is relatively easy with some masonry experience and does not require any special permits, but always check with your local building department before starting any landscape project.
