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.
Pool Security Covers: Prices for Security Covers range from $1300-$3000 in most cases. Heat Pumps: Most heat pumps cost between $3500-$6000, plus additional cost for electrical hook up. Waterline/Perimeter Tile: Most pool dealers charge between $1500-$3000 to tile a fiberglass swimming pool (on the waterline). Retaining Walls: Retaining walls can get very expensive, and depending on the size can obviously vary a huge degree. Most walls cost $5000-$15,000.
