A speculative investigation of ways to constructing intelligent agents that work as independent spatial features or combine to assemble virtually infinite constructs. The ‘Angel’ project plays with architectures historically rigid nature playfully looking at the possibilities of an architecture lighter than air capable of sheltering us and even bringing communities together. The initial concept developed out of a building proposal in which a conversation space could transform its spatial conditions reacting to a set of protocols based on inhabitant’s conversations. The constantly reconfiguring space was actuated by a series of floating agents that could descend, rise, approach and retreat from the people within the space as well as articulate a range of behaviours. These “Gestures” attempted to act as catalysts for the generation of new conversation and interaction. This investigation led to the exploration of LTA (Lighter Than Air) Vehicles capable of acting independently or in flocks constructing dynamic spaces for people to meet.
