Every architectural project begins with modelling, and while David Umemoto's concrete sculptures are a direct reference to brutalism, they aren't likely to see production on a building's scale. That's because the sculptures aren't actually designed to be buildings. Rather, they're studies in volume and form as it relates to concrete.
Through David Umemoto's sculptures aren't buildings, they have many structural components that buildings do have. Several of the volumes' edges are jagged, looking like stairs, and there are further punctuations around the sculpture that look like windows and doors. In most cases, these gestures are placed in inaccessible areas or an nonsensical angles, giving the sculpture the appearance of a more drab work by MC Escher.
