Hi all,

I'm new to the forum so please be gentle. I'm currently in the planning process of building my first pond. while i have sourced all the equipment and information needed to run and sustain the pond I still havn't quite worked out how to build it.

I'm going above ground as it is a formal pond. I have looked at concrete bricks and other ceramic materials but all leave me feeling as though i have taken an easy way out contruction wise while also creating a 'weak' structure when it comes to gound movement, ie cracking of brickwork.

so i have decided on a timber framework much like the stud framing of a house.

Rough dimentions of the internal walls will be 2000 w X 2000 L X 900 h giving me close to 4000 litres. what would be the best way to contruct the framework for both bottom and sides? keeping in mind i will be lining the inside with 12mm ply and also the pond liner itself. will 450 centres and noggins surfice to take the weight of the water on the side walls or will i need to reinforce with diagonal cross members on the outerside of the wall to the floor frame? was looking to use 45x90 treated pine for the framework.

Thanks for your help
Cheers
John

Gday John,
A mate of mine recently picked up a used working above ground spa about the same dimensions for $150. Would be easy to reclad it & no structural or water proofing problems.
Also pool fencing will probably be an issue for you to consider.
Cheers
