Dear John: Designing Arena Kick Walls
Hello John,
I’m meeting with an arena builder this morning. It’s finally clearing up around here, so we hope to start constructing the forms for the barn foundation this week.
Q: Do you have any advice about a design for a canted ring liner? Or even just describe what is the norm? We need an idea of how a segment typically is built.
Is it a good idea to go on up vertically after the canted part, another couple feet, to get a better compromise between indoor and covered only?? Or would that be claustrophobic? We plan to use gale shields (netting panels) to cover the openings/protect from rain and wind.
Thank you!

A: Dear Northwestern Eventing Rider:
I’m not sure what you mean by “ring liner.” Do you mean the kick wall?
There are a variety of ways a kick wall can be designed. I typically design it to the height the owner requests (typically around 4 to 6 feet). We kick the base of the wall out about a foot from the top so it is slanted to protect the rider’s leg.
The top of the kick wall can go to whatever height you feel comfortable but I would make sure if you are using a steel frame for your arena roof and the interior face of the steel column slopes inward, that you allow some extra space between the top of the kick wall and the front edge of the column so that the rider’s shoulder or head doesn’t come in contact with the column.
I suggest extending the kick wall into the footing to the gravel base. Remember, the bottom boards and the framing behind the kick wall should be constructed of treated wood wherever it comes in contact with the ground or grade. In most cases the frame is constructed of pressure-treated lumber and the bottom boards are pressure-treated to a point about 18” above the footing surface.
Also, I suggest putting gravel in back of the kick wall to the height of the arena footing to prevent the footing from being driven over time under the kick wall by the pounding of horse hooves.
I hope this is helpful.
Good Luck,
John
Arena Design – Tips and Considerations
Size & Scale
When designing, I’m often concerned about maintaining proper scale and proportion. In equestrian design, arenas in particular pose a challenge simply because they are such large structures. An arena is never small, but since different riding styles determine the amount of space required, it’s important to first understand how much space you need. Once you gauge the room necessary to ride, you may consider some of the following elements to design a proportionate and functional arena.
Lower the Stakes
Arenas of all sizes benefit by lowering the structure within the site. Push the structure into the ground and the visual height is greatly reduced. Typically, I recommend lowering the arena four to five feet into the ground. That way you can create an observation area on one or more sides, that has visibility over a kick wall or fence, with an on-grade entrance from the exterior. The “bird’s eye view” observation area is excellent for spectators and the lowered grade takes full advantage of the site without increasing the structure’s bulk.
If there are several facilities on your site, carefully placing the arena amongst the facilities you have—or the ones you plan to build—can help to break up the arena’s large scale. The slope of the roof is often overlooked in prefabricated arenas; often too-low roofs of these structures offer only a massive, box-like look. If, however, the roof is sloped at five in 12 or greater, the arena can appear smaller and fit more naturally into the landscape. Sometimes you’ll run into zoning or code restrictions with height, so lowering the arena into the ground can literally give you more working room.
Covered vs. Enclosed
Geographic location is everything when considering an enclosed, covered, or open arena. An enclosed arena is probably necessary in cold or windy climates. Roll-up garage doors with translucent or clear panels on all sides of the arena can provide an indoor-to-outdoor feel; just open it up when the weather permits or, alternatively, close it up during inclement weather.
Lighting
We try to take advantage of natural light in all of our designs—from equestrian to residential—because natural light really can’t be beat. A continuous ridge skylight is the most effective method to achieve this, and the technique also increases natural ventilation within the arena. Operable louvers can further contribute to natural light and ventilation while maintaining control as you adjust them accordingly. Any glazing used should be translucent to avoid creating shadows that might confuse a horse. While a large skylight is a more expensive option, various materials can reduce its cost. A naturally lit arena doesn’t rely on electric lights during the day, which is another bonus for horses and riders.
