McMansions, housing markets, and the influence of banks

An Australian architect argues homes should be valued on newer tastes rather than older interests in McMansions:

Recent sales and development figures have highlighted a trend towards smaller living spaces but the system for valuations in the capital seems biased towards larger average quality homes, Canberran architect Allan Spira said…

Mr Spira said building smaller, more affordable and sustainable homes will only be an option for “cashed up clients” unless the current system of valuations is changed.

“It’s time for the banks and their valuers to stop basing their assessments on the ‘McMansions’ of the past and start acknowledging the way of the future – smaller, smarter, better fitted out homes,” he said…

Mr Spira said most recently his clients struggled to get a $300,000 loan to build their three bedroom home in Wright.

Built across 127 square metres, he said it was “probably the most affordable and sustainable home in the suburb” but valuers CBRE based their calculations on inappropriate figures as no previous sales figures existed in Molonglo.

It might be hard to make a larger argument based on two cases. But, this argument does raise some larger issues:

1. Just when exactly do bankers and others know when the housing market has turned? In this case, the architect suggests people now want smaller homes compared to the McMansions they wanted a few years ago. It is easier to see change over the course of several years or a decade but it is harder to see this in the short run.

2. How much do banks and their choices about mortgages influence house purchasing and building patterns? Banks were partly blamed for the housing meltdown in the late 2000s but what percentage of blame do they deserve? I haven’t seen someone parse out the particular effect banking and mortgage choices have on what homebuyers are willing to do. This architect suggests homes aren’t being built because banks won’t provide financing for them but it is not clear how often this really happens.
