Langtree has been named as the preferred developer of the Kingston House site in Liverpool city centre.
The site, which is owned by the Northwest Regional Development Agency (NWDA), is at the corner of Strand Street and James Street.
The site has been earmarked for a 100,000 sq ft (9,290 sq m) office building of between 10 and 12 storeys once the existing 1960s building has been demolished.
The selection process was run by regeneration agency Liverpool Vision. Martin Lloyd, NWDA head of property, said: ‘A new landmark building in this important location will help to continue the transformation of Liverpool city centre.’
