Huge houses on the urban fringe are an irresponsible drain on the environment, according to this opinion piece by Dr Robert Crawford from Melbourne University. There are two charges here – one is that the average 238m2 greenfield house is too big and the other is that the occupants are too reliant on cars for transport. I discussed the transport issues related to greenfield houses recently, so this time I want to look at the allegation of excessive dwelling size.
There are all sorts of problems with the “too big” criticism, not least the obvious question: what is the “right” size for a dwelling? Even if that question could be answered satisfactorily, there’s another – what should be done about it? Should there be regulations limiting the size of houses? Or perhaps a “McMansions” tax? I think there’s actually a sensible way to approach this issue which I’ll come to in due course. But I want to start with some pertinent observations.
First, greenfield houses mostly aren’t as big as epithets like “McMansion” imply. When Melburnians think “McMansion” they usually have in mind a two storey house like Metricon’s 530 m2 ‘Monarch’, which is more than double the size of the average greenfield house. In the US however, the term McMansion is reserved for much, much bigger houses on very large lots like Tony and Carmela’s spread in New Jersey (see first picture). The average house on Melbourne’s fringe, however, is a much more modest 238 m2 according to Dr Crawford’s own evidence. That’s big compared to an inner city apartment but it’s much smaller than the ‘Monarch’ and much smaller than any reasonable definition of a McMansion. Further, more than two thirds of houses in Melbourne’s greenfield areas are single story. Nearly half (47%) are smaller than 240 m2. Almost three quarters (74%) are smaller than 280 m2.
Second, fringe houses aren’t much bigger, if at all, than typical houses in some older suburban areas. I live with my family 8 km from the city on the border of Ivanhoe and Alphington where most dwellings were built before WW2. Having two children who went to Alphington Primary School means I’ve seen inside many, many homes in the Alphington, Fairfield, Ivanhoe area. I can’t recall ever being in a house in these neighbourhoods that hasn’t been extended at least once in its lifetime. And while they probably were once, these aren’t small houses anymore. For example, the external dimensions of our place, including the garage (but excluding decks), is 240 m2 and it’s by no means large relative to other detached houses in the area – in fact I’d say it’s about average or perhaps even a bit smaller. Yet I don’t hear many complaints that inner suburban homes are “too big”. Read the rest of this entry »
