In German, coop has a similar meaning to the English "co-op". In German, Himmel means “sky” or “heaven”, and blau means “blue” while bau means “building” or “to build/construct”. So, the name can be interpreted either as “Blue Sky Cooperative” or “Heaven Building/Construction Cooperative”.
The office has been trying to change the usual design paradigm since its foundation. The office tries to develop a radical design truth a realistic approach. Their Ideal is to work with complex shapes coming out of a complex process in which the architects mix different mediums such as models, 3-d modeling, parametric tools, sketches and drawings in order to create an unexpected design. The philosophy of the office can be summarised with their 1980s manifesto “Architecture must blaze:”.
"We want architecture that has more to offer. Architecture that bleeds, exhausts, that turns and even breaks, as far as I am concerned. Architecture that glows, that stabs, that tears and rips when stretched. Architecture must be precipitous, fiery, smooth, hard, angular, brutal, round, tender, colourful, obscene, randy, dreamy, en-nearing, distancing, wet, dry and heart-stopping. Dead or alive. If it is cold, then cold as a block of ice. If hot, then hot as a blazing wing. Architecture must blaze!"
