Helsinki city planning departments english website has an interesting flash video covering the four current major urban building projects within the city at Arabia Waterfront, Pikku Huopalahti, Ruoholahti and Viikki. This gives a good overview of current urban strategy, architectural work and planning in the city. Planners are not my favourite profession exactly but what they are doing here is quite interesting. The architectural work covers much ground too from the deeply Miami beach uncool of Pikku-Huopalahti to the modernist eco-friendly Viiki developments.They are also going to be building on the Eastern Harbour a whole new ‘waterside quarter’ where the docks are currently.
