SOM Arrowhead

With the weird looking skyscrapers, there’s a business problem of having expensive, unusable space.  Often, the most pragmatic, profitable shape is the plain old rectangle.  So for the sake of staying grounded in reality, today I’m going back to the boxy, modern-style skyscraper.  Above is Arrowhead, a 525,000 sf office building under construction in South Quay, London (UK) by Skidmore, Owings & Merrill.  The 26-story building is expecting an "excellent" rating under BREEAM, the environmental building assessment tool used in the UK.  Among other green features, Arrowhead will have a green roof on the top and a mid-level rooftop terrace.  The building also has a glass climate wall with external metal shading to retain heat gain in the winter and permit cooling in the summer.
