In December our thoughts turn to Christmas. We think about our family, friends, Christmas cards, food (lots of it!) and presents - will Santa pass by this year? Also, just as important, the reason for Christmas: the birth of Jesus. But what we also think about is the weather - will it snow? This question set me thinking – why do we feel Christmas isn’t really Christmas if it doesn’t snow?

London is growing skywards. With the high rental price for offices and a lack of space in the ‘square mile’ of the old City of London going up is the only practical alternative. Because of the soft clay in which London was built the maximum height of a skyscraper in the city used to be around 600 feet (200 metres) but new technology allows architects to design buildings – such as Enzo Piano’s The Shard – which are around 1000 feet (300 metres) high with further high rise structures being built and planned for the future.
