土地 & Site Preparation

Land condition largely determines the initial budget.

Flat land with good drainage → lower earthwork & foundation cost

Uneven terrain, slopes, or landscaping → higher construction cost

Soil reinforcement, waterproof layers, and underground pipelines can also increase expenses.

Water play structures for kids

Splash pads and spray zones

Tipping bucket water playgrounds

Lazy rivers / mini rivers
Pools and-water interaction areas
Material quality matters:
