The nation's housing shortage requires innovation to solve it and this proposal to convert ugly out of town retail space to housing merits further examination. It is hard to think what is not to like. Those of us watching the slow creep of development into our green spaces would love the idea, which could in theory at least let us re-use land which might otherwise go to waste. How ironic that those of shopping on line from the comfort of our sofas might in future be doing so inches from where we once dragged our moaning offspring on endless shopping trips!
