Create A Pond In A Box
Normally, installing a fishpond involves digging a sizeable hole in the ground, which in turn means hours of back-breaking toil with a spade and shovel.
This pond requires much less elbow grease, with an elevated design that comprises a simple box with a pond liner for a no-dig solution.
Before you start, check with your local council to find out the maximum permitted depth of a water feature before any fencing is required.
In many areas a maximum depth of just 300mm is allowed. This legislation was introduced to protect young children from tragic accidents.
The elevated design of this project makes it a safer option than a typical in-ground pond, as it’s less likely that a toddler could trip and fall in.
Choosing a suitable location is important, since prolonged direct sunlight will excessively heat up the water, promoting algae growth.
Even worse, it would only take one severe summer scorcher for your goldfish to cook in their pond.
You will also need to install the pond close to an outdoor power source so you can connect the pump that supplies the fountainhead.
Choose the materials
Use concrete stepping stones and roadbase as a foundation, with H4 treated pine for the footing plates and baseboards. The rest of the structure can be built from H3 treated pine.
Hardwood can be used instead of treated pine, but keep the section sizes similar so the structure will be strong enough to hold the weight of the water.
Use 30 x 30mm treated pine quad beading for the corner blocks and 25 x 25mm aluminium angle for the flashing over the baseboards.
To finish the project, install a reticulating pump and feed the hose through the slot in the liner capping.
Round over the edges of the top capping, secure a fountainhead to the trellis and apply two coats of exterior enamel or acrylic paint.
Use 65mm x 10g exterior timber screws for the main structure, including the footing plates, stud walls, base and top plates, capping and trellis frame. Attach the cladding boards to the stud walls with 40 x 2mm galvanised nails.
