The Challenge

Four Kingspan Round Rainwater Tanks in corrugated steel with galvanised finish .

The original 'Argyle' Victorian heritage house used a 2,500-litre tank for vegetable garden watering and flushing toilets.

For the contemporary, sustainable living project, S2 design chose to install a maximum of rainwater storage to fit into the new basement to fulfil the aim of achieving (almost) total water independence from mains water.

A thorough water study identified the project required sufficient water for a family of four, a large dog and an Australian-first 'roof farm', a new approach to sustainable inner city living and a new interpretation of permaculture.

A visually spectacular design in contemporary architecture, the project was also significant for its social, functional and environmental considerations.

Application Kingspan manufactured 4 made-to-measure water round tanks of 10,850 litres (2.4m diameter x 2.4m high) to fit precisely within the constraints of the tight basement space and supply almost 45,000 litres of rainwater to the home and garden.

The flat tops on the steel tanks allowed more water storage than alternative tank types, which often feature domed or angled tops.

The surface finish of the tanks is a perfect complement to the exposed galvanised finish of the building structure and construction details.


The Challenge


"Kingspan collaborated with S2 design to ensure the tanks provided the most efficient solution to the space limitations of the project. The delivery crew were especially helpful in assisting to move the four enormous tanks down to their new home in the basement."
