+1 My experience as an architect and as an office worker confirm what you say. Somehow a mixed solution is the best. Spaces for small teams (max. 5 people), keep some privacy but also allow communication. Spaces of 15-20m2 are perfect for that, making a small house the best option. "Normal kitchen, front-yard and even attic for stuff" are also a great complement.
