Thank you, Deputy Presiding Officer. Can I first of all thank the Minister for her statement? Can I start with two long-standing views of mine? We need more housing, especially council housing, to meet the need, and, secondly, we need to return to the Parker Morris standard or a standard very similar to it, which is based on the premise that a good house or flat can never be made out of premises that are too small. Also, their home, for many people, is now becoming their workplace as well.

I welcome the Government's view that gone are the days of MMC's association with poor-quality, temporary, prefabricated housing. MMC now produces high-quality, desirable, energy-efficient, affordable homes that tenants can be proud of.

I'm sure the Minister remembers, because it's affected her constituents as well as mine, steel houses and other non-traditional builds such as high alumina cement in schools such as Olchfa that either had to be knocked down or fully refurbished because of problems with construction.

I have two questions: what is the life expectancy of these buildings and how has it been calculated? And, secondly, how do you calculate the energy efficiency of modular construction houses?
