The dark exterior of Zaha Hadid’s Riverside Museum in Glasgow belies an acid green interior which bathes the vintage cars  and old steam trolleys in an oddly generous and unusual light. The waterside transport museum comes after so many refined Mackintosh tea rooms and all white bedrooms and is the perfect jolt into the 21st century. This was one of Hadid’s last commissions and one wonders where she might have gone from here.
