Housing and the Election?

The Conservative Party, in the run-up to the General Election, has now 'offered',if re-elected, to legislate for up to 200,000 cheap starter homes for people under 40 on brownfield sites without requiring the builders to consider providing additional local services (such as roads, schools etc) or affordable housing. This has led to a boom in the building industry's shares (http://www.cityam.com/210591/housebuilder-shares-rise-conservatives-promise-200000-cheap-starter-homes-first-time-buyers). There are a few points to note although I do favour brownfield rather than green sites. Making brownfield sites appropriate for house building can be quite demanding and an expensive process. The difficulty is that someone would have to pay for this (and perhaps the missing amenities in the chosen areas). The locations might also turn out to be pretty unattractive in the longer term.
