A few questions for those that have had them built on their own property. What type of surface did you use? What boundary fencing/border did you use? What companies/contractors will level out the ground? Are there any companies/contractors out there who will do the whole lot (leveling/compacting/surfacing)? Approximate cost (PM if you prefer)? Parents have FINALLY (after nearly 20 years of owning horses) agreed to build me an arena Thanks Dad!!! The area I am using is a very dry, well drained patch of soil, measured at 40mx20m (would have preferred 60x20 but too many trees in the way), so hopefully water logging wont be a huge problem.
