Grainger's evolving development business is increasingly focused on large and complex mixed use projects. The recently strengthened management team is based in London, Newcastle and Oxford, thus ensuring good geographical coverage. The development team works closely with local authorities, the local communities in which it develops, joint venture partners and all relevant stakeholders. It is these relationships which underpin Grainger's approach to its development business.

The current programme includes up to 7000 residential units and 2million sq ft of commercial space including health care facilities, children's nurseries, a community theatre, a cemetery, schools and sports and recreational facilities.
