Recently some members of the 5to50 team enjoyed an offsite conference (ahem, much-delayed honeymoon) in Greece. There was sun, sand, warm water and plenty of tzatziki of course, but we also loved looking at the Greek building methods – especially on Santorini. Residential construction in Greece seems to be fairly simple – it’s formed up, concrete is poured and, in Santorini at least, the roof is quite often concrete as well. Inside, the walls are rendered but there’s no lining or gyprock and in general, all the floors are tiled. The walls are lovely and thick which gives the buildings great thermal mass (it gets mighty hot on those idyllic islands) and external shutters are also part of the design to stop the summer heat from getting in through the windows.
