+        Colouring London is a citizen science platform collecting information on every
+        building in London. We're building it at the Centre for Advanced Spatial Analysis,
+        University College London, to support sustainability research and we're looking for
+        volunteers of all ages and abilities to help.

+        All you need to do is add information on any London building, to help create beautiful,
+        coloured maps, and a free statistical database for everyone to use. Or just view our
+        maps and test our site before we launch officially next year.
