Andy and Nicki Bruce try to build an experimental flood-proof floating house on an island in the River Thames. But building such a complex design on a site with limited access is not easy.

Andy and Nicki Bruce's amphibious house, the first of its kind in the UK. Their architect has come up with an ambitious, experimental design that has never been tried on a river bank in Britain and no one knows whether it will work.

The Bruces decide to build on a site on a small island in the river. But it's not long before the project becomes bogged down in the logistical challenges of building such a complex design on a small island that is only accessible by a narrow footbridge.
