THE architect who had been commissioned to design the National Trust's new headquarters in Swindon has died.

Richard Feilden, 54, died suddenly on January 3.

He was based in Bath but since 1998 had practised with increasing success in London.

His concern about environmental issues led the practice to obtain the commission to create a new headquarters for Greenpeace in an old building in Islington.

Appropriately, he placed an emphasis on the use of renewable resources and economy in energy consumption.

His approach to the building won praise from within the industry and the success of the project led to commissions for the New Environmental Office for the Building Research Establishment and the National Trust's new headquarters in Swindon, next to Brunel's engineering workshops in Churchward.

Mr Feilden leaves his wife and three children.
