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.
On average, a pool enclosure that is screened can cost anywhere from $13 to $24 per square foot. Cheaper inflatable enclosures can cost around $7,000 to $10,000 for a typical inground pool. An aluminum screen enclosure can cost anywhere from $15 to $30 per square feet. Higher-end enclosures made from glass can cost as much as $50 to $65 per square feet.
