The boatyard owner Myck DjurbergCredit:NEV AYLING They hoped to permanently berth their houseboats at Mr Djurberg’s idyllic Hampton Riviera Boatyard, located close to Hampton Court Palace.But the absence of mooring licences and residential planning consent made it impossible for them to stay, explained their barrister, Adam Rosenthal.The Smalls’ said they have been forced to park their £1.25 million houseboat – a 5,000 square foot vessel called Willowbank – in a local storage facility.They had hoped to move on board with their two children, and create “a fantastic home in a great location”. But instead they have quit Hampton Riviera and cannot move the boat to elsewhere on the river because the vessel’s sheer bulk makes it impossible to find a berth and it cannot fit under bridges, they claimed.Ms Johnstone said she and her partner moved into their houseboat with their teenage son and a piano in 2015 – having agreed an £850,000 purchase price.They were left “traumatised” when they later realised that they had no permanent right to live at the marina, and that “we’d been sold something that didn’t exist”. Two couples who paid millions of pounds for two luxury houseboats have taken the seller to court after they discovered they are “worthless” and cannot be moved to a different mooring due to their size.Oliver and Jennifer Small and Fiona Johnstone and Louis Sydney claim they bought their giant floating homes from entrepreneur, Myck Djurberg, on the clear understanding that they came with 125-year mooring licences.But each couple had their dreams dashed when they discovered the vessels had been sold to them without mooring rights or planning permission, the High Court has heard. The houseboat was later repossessed and sold on by Mr Djurberg, the court heard. Mr Djurberg claimed the Smalls owe him arrears of mooring fees, although both couples say they are victims of his “misrepresentations”.He insists that the couple moved in without his permission as most of the purchase price was still outstanding. On top of that he denies ever giving assurances that their floating home came with a 125-year mooring licence.The issue of residential planning permission was something that needed to be hammered out between the boat owners and the local authority, he maintains.The hearing before Judge Murray Rosen QC continues.
