- There must be an assurance that a property will gain value, ergo there must be more accessible, cheap and effective schemes for developing and improving buildings - i.e. research into extending buildings in unconventional ways ; as opposed to just loft conversions and simple extensions, e.g dramatic additions to the height which are structurally viable and aesthetically pleasing. This has the potential to create interest , and if done correctly could become a feature of the city- a series of houses that are constantly developing , growing or altering to suit the needs of its inhabitants.
