As a keen runner, running through Greenwich Park and on to the river side I see the Thames Barrier, which is not only the worlds second-largest movable flood barrier (after the Oosterscheldekering in the Netherlands) but is also an iconic site on what is fast becoming a recognised stretch for developers including the 02 and Ravensbourne College of Design and Communication.
Having spent many years studying there, I have a soft spot for Central Saint Martins, which finally closed in September 2011 when the college relocated to Kings Cross. Despite being such a dive, the old building had such history and character and I grew very fond of its tatty charms. As plans for its take over by Foyles bookshop go ahead, I look forward to having a coffee in the new building's cafe when it re-opens.
Slightly biased as this is where I live, but Stoke Newington is great place to spend lazy saturday / sunday afternoons getting sloshed with friends. There are 10 + pubs within walking distance who all are great places for one reason or another. I'll pick out the White Hart for its huge beer garden...
