The publicity for KX tells us that “King’s Cross is the largest mixed use development (27ha) in single ownership to be master planned and developed in central London for over 150 years”. It certainly has taken a long time in gestation (since the mid-1980s), been highly controversial, but makes an enormous amount of sense. The issue has always been how should these railway lands and historic buildings be developed? – an issue prompting endless debate, contention and negotiation between developers, stakeholders and neighbouring local authorities (Camden and Islington). The core to the rationale for development is that KX is a major national railway station adjacent to another, St Pancras – and is a logical place for dense commercial development. However, the location is also one of transition between the West End and local residential areas.
