A row between celebrity jewellery designer Stephen Einhorn and his architect has spilled over into the High Court
Einhorn, whose bespoke designs are worn by celebrities including Fearne Cotton, guitarist Slash and the cast of True Blood, says an extension to his home, on Upper Street in Islington, North London, was ruined by water leaking in.
The jeweller is suing Simon Powell Architects for damages of around £100,000 for alleged negligence and breach of contract.
He engaged Simon Powell to prepare a design and specifications for an extension and alteration to his four-storey Victorian terraced house. The project involved replacing the third floor with a new storey, with a mansard roof and dormer windows. Einhorn had planned to live there with his family, according to a High Court writ.
Contractors started work in June 2002 and, although work should have finished by November 2002, no certificate of practical completion was ever issued, and the family moved in in June 2003, the writ says.
The writ also claims Einhorn discovered the Islington work contained numerous defects, with water coming into the property leading to structural damage.
He accuses Stephen Powell Architects of failing to use reasonable skill and care in conforming with usual architectural standards, failing to carry out weekly inspections, failing to issue contract drawings in time and failing to observe defects in the work.
Rectification work cost more than £42,000, while other repairs, replacement of property, carpets and other items bring the cost to more than £90,000, it is alleged
