George looks back at his first ever big build, in which he enlisted the help of friend and design guru Will Hardie to convert a dilapidated 1970s caravan bought for £300 into a stylish holiday home for him and his children. Along the way, George takes inspiration from other ingenious caravan and self-build conversions, including lovingly restored gypsy wagons - and to make the most of the space, he even comes up with a sofa that doubles up as a bath.
