Norwich Union is planning to convert a 1970s office block in Leeds city centre into 130-bedroom hotel and leisure scheme.

The office, Dudley House, is adjacent to Halifax’s St Anne’s Quarter retail and leisure development on the Headrow.

It is understood that Norwich Union will submit a detailed planning application to Leeds City Council early this year to redevelop the 10,870 sq m (117,000 sq ft) office to create a two- to three-star hotel, and 5,574 sq m (60,000 sq ft) of licensed leisure and health and fitness.

Norwich Union hopes to create bars and restaurants which will complement the Halifax development, and the estimated end value of the scheme is £20m.

Knight Frank is the letting agent.
