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.
The cost to set up a saltwater pool will cost between $1,000 and $5,000, not including the cost of the construction of the actual pool. This cost also depends on the size of your pool---the larger the pool, the more water you have and, thus, the more salt you will need to add to the water.
