This Practice Note provides a summary of some of the ways in which a residential flat development might be structured. It aims to provide an overview of different leasehold flat schemes for both developers and purchasers of residential flats. A key consideration in residential leasehold developments is ensuring that there are adequate enforceable obligations in place for the repair, maintenance and insurance of the common parts of the development (ie the structure, foundations, roof, main walls, internal and external common parts and common services). The following development schemes, and their different methods of dividing responsibility for the common parts between landlords, management companies and tenants, are considered below: • developer/landlord retains reversion and management responsibilities • developer/landlord retains reversion but contracts out management responsibilities • developer/landlord retains reversion and tenants take on management responsibilities • developer/landlord disposes of reversion and management responsibilities to the tenants • ‘criss-cross’ or ‘crossover’ scheme • ‘cat’s cradle’ scheme This Practice Note does not consider commonhold developments; for information on commonhold, see: Commonhold—overview and Practice Note: Residential flat schemes—leasehold v commonhold.
