This project was commissioned by East Thames Housing Group to investigate the relationship between: increasing housing densities, dwelling mix and built form, and the incidence of service charges; the affordability of service charges to tenants and LCHO purchasers; whether particular service charges are associated with changes in built form and whether these can be linked to predictable ‘break points’ in housing density, to produce a ‘typology’ or archetypes for planning and financial feasibility purposes.
