We have seen a number of floods in recent years, with the media describing them as \u201cunprecedented\u201d. The implication is that these floods were unavoidable and homeowners have been unlucky.<\/p>\n
However, building practices in England mean that homes are often built in high-risk areas. According to The Environment Agency, a high-risk area is one that has a greater than 3.3% chance of flooding each year.<\/p>\n
And over the last few decades \u2013 between 1989 and 2016 \u2013 more than 300,000 homes have been built in high-risk areas. Essentially, these homes have been built on floodplains and in coastal areas where flooding is a distinct possibility.<\/p>\n
Therefore it is the planning system itself that has been a factor in increasing the risk of homes being flooded.<\/p>\n
The floods in Fishlake, near Doncaster, in November 2019 showed exactly what can happen when we build on floodplains. Fishlake lies beneath the high water level of the River Don, and back in the days when it was farmland rather than houses, farmers avoided planting crops there because the ground was so waterlogged.<\/p>\n
It is not surprising that 500 homes were flooded when the river broke its banks. Even the name of the area, Fishlake, should have been a clue as to the likely outcome of building there.<\/p>\n
Clearly, the ideal scenario is that developers stop building on flood plains. However, that seems unlikely to happen. A Greenpeace investigation has found that 9,688 new homes could be built on some of the most flood-prone areas of England\u2026 including hundreds of new build homes in Sheffield and Doncaster.<\/p>\n
Proposed developments include 3,100 properties in a \u201cnew town\u201d less than two miles from Fishlake, and more than 5,000 homes in a high-risk flood zone in Lincolnshire.<\/p>\n
If developments are going to continue, despite the risks, it would make sense for developers to build homes that are \u201cflood proof\u201d.<\/p>\n
It is not always straightforward to make a home flood proof, and it is not always budget friendly to do so. But it is something that needs to be addressed.<\/p>\n
A recent project on Eel Pie Island in Twickenham \u2013 where the Rolling Stones performed before they hit the big time \u2013 saw us designing a timber-framed house on stilts. And we have done a few of these along the Thames where homes have been raised up well above the water level.<\/p>\n
Another innovative solution seen along the Thames near Marlow, in Buckinghamshire, is an amphibious house that is designed to rise upwards when the area floods. Since the house moves with the water, there is no need for stilts.<\/p>\n
If developers can embrace flood-resistant designs, then continuing to build on flood plains won\u2019t be a problem. The fear is that standard homes will continue to be built in high-risk areas, causing inevitable problems for the people who buy them.<\/p>\n
