Roald Dahl's writing hut

Google 'shed art' and a thousand links and images fill the screen. So why do so many contemporary (and not so contemporary) artists, writers and poets use, explore or adapt the shed as a motif, symbol, exhibit or location.  Are there common underlying reasons? Is the shed revolutionary or reactionary, retrograde or reinventive? There seem to be some obvious answers but what do you think? Make your comments here...
