Columns placed inside the wall on 20' to 30'spacing extend from 18 to 36 from the wall into the interior of the building. With the installation of backdrops and player access alleys the effective space for a tennis court is only 114' +/-, some 6' less than most players are accustomed to. The resulting undersized courts have lead to numerous law suits with players claiming injuries for running into columns or walls.
First, letâs look at the cost of actually building a pool. Obviously, the fancier the pool, the more expensive it will be. On average, an in-ground pool can cost anything from $12,000 to $50,000. An above-ground pool may be a bit cheaper.
1 An average-size pool that is 30 to 35 feet in length and 4 or 5 feet deep might cost $25,000 to $30,000. 2  That does not include any extra features or decking. 3  A pool that is the same length but 6 feet deep with standard concrete decking, upgraded lighting and a diving board might cost $30,000 to $35,000. A pool that is the same length but 6 feet deep with standard concrete decking, upgraded lighting and a diving board might cost $30,000 to $35,000. 2  A large pool-say 40 inches long and 6 feet deep-with a spa and heater, upgraded stamped concrete decking, upgraded lighting and a diving board might cost $50,000 or more.
