NBBJ is establishing itself as the architect of choice for internet giants after it partnered with Amazon for a Seattle Headquarters just over a year ago. The team has just released glittering revisions for the Amazon HQ where one of three ‘blocks’ has been substituted for a shimmering cluster of biodomes. In total this alteration will cost the development approximately 19,000 sq ft of internal space however the low-rise nature of the structure gives it a number of positive attributes including the reduction in shadow and shade impact and the widening of entrances along the 6th and 7th Avenue to the Public Plaza and Commercial Parcel Park.
