A furniture designer successfully sued the seller of a £700,000 house he bought after he found Japanese knotweed in the garden, a court heard.

Jonathan Downing, 30, bought the home from chartered accountant Jeremy Henderson, 41, in August 2018.

While tidying the home’s garden in Raynes Park, London, just after he moved in Mr Downing discovered the knotweed.

Japanese knotweed is an invasive species, causes damage to building structures and is expensive to get rid of.

Mr Downing then sued Mr Henderson for £32,000 for failing to disclose there was knotweed when he sold the home.

Mr Henderson answered ‘no’ to the question on the TA6 property information form asking if the property had been affected by knotweed and claimed he couldn’t see it because of a large bush.

Mr Downing said if Mr Henderson had filled out ‘not known’ on the form instead, he could have investigated the matter further.

But there was evidence presented in court that the knotweed stood at least two metres tall at one point and was treated with heribicide.

What is Japanese knotweed?

Japanese knotweed is a species of plant that has bamboo-like stems and small white flowers.

Native to Japan, the plant is considered an invasive species. 

Although it rarely sets seed in this country, Japanese knotweed can sprout from very small sections of rhizomes. Under the provisions made within Schedule 9 of the Wildlife and Countryside Act 1981, it is an offence to cause Japanese knotweed to grow in the wild.

The invasive root system and strong growth can damage concrete foundations, buildings, flood defences, roads, paving, retaining walls and architectural sites. It can also reduce the capacity of channels in flood defences to carry water.

Avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene, and encouraging or introducing natural enemies should be the first line of control.

If chemical controls are used, they should be used only in a minimal and highly targeted manner. For example, where pests, diseases or weeds pose a serious threat to the wider environment, to important heritage specimens, to habitat, or to native wildlife.

At Central London County Court, Mr Downing’s barrister Tom Carter said the knotweed had been in the garden since 2012.

Mr Henderson had moved in during 2015 and then sold the house to Mr Downing in 2018.

Mr Henderson told the court: ‘I had lived there for three years and spent quite a lot of time in the garden and hadn’t seen knotweed.

‘I got a surveyor’s report when I moved in and it didn’t find any knotweed.

‘No one identified any knotweed to me and I didn’t see any knotweed.’
