If you know that you’re gonna add these items in the future, have your builder make provision for the added equipment. For example, when adding a slide, have your builder install a water source in the deck near the future location. When adding a heater, if it’s gas, make provisions for the gas line and make sure the equipment pad is large enough. If it’s a Heat Pump, make sure the wire going to the equipment pad is large enough to handle the additional load.
