So how much space do we really need? I was listening to a program recently where Stuart Harrison (a Melbourne-based architect and the author of Forty Six Square Metres of Land Doesn't Normally Become a House) suggested that 40 square metres per person should be sufficient, provided that there is adequate outdoor space as well.
So if I take this advice into context for my situation, I would need a house of about 240 square metres. I estimate that our total living space will be about 195 square metres, which falls somewhat short of the suggested amount. Does this mean our house will be inadequate? I'll have to let you know.
