| Hi Oli
You could try and incorporate a pool and waterfall system using preformed pools like you get at shows and carefully hidden liner waterfalls connecting them. If you imagine using concrete blocks in a stair fasion with ply board or other wood placed on top, these would be connected to the pools and covered in liner. Each could then be raised off the ground and a bottom drain placed underneath.
With a little thought this could look quite natural and be covered with foliage pond plats and rocks etc.
Alternatively and possible the costliest option would be to create your idea in a lego block fashion with all of your pipes and drains in place all covered in heavy duty plastic. This could then be fibreglassed and would not ruin the store floor and could be removed later
good luck |
