A battle over architects' fees for one of the most ambitious private developments in London is heading for the Court of Appeal. Leave has been granted to Christopher Moran to challenge an order by the Technology and Construction Court that he must pay architects Carden & Godfrey £82,500, which they claimed is owing. The money is said to be owing for, among other things, formation of a quadrangle at Crosby Hall, Cheyne Walk, Chelsea, and design of a ramp and access to underground car parking in the south wing of the quadrangle. Moran claims that the firm was negligent and refused to pay the bill. But in the Technology and Construction Court Judge David Wilcox ruled that there was no merit in Moran's allegations that the firm in fell short of its duty to exercise reasonable care.
