半成品住宅：先盖一半，另一半留给住户

Design an incremental housing scheme in the manner of Alejandro Aravena's Villa Verde — each unit built as half a good house, with the structure, kitchen, bathroom and roof provided for the whole footprint but one bay left as an open void that the family fills in themselves over time. Compose a terrace of pitched-roof timber and concrete houses where alternating bays are complete and others are still open framework, some voids already infilled by residents in mismatched materials, a gravel street with parked pickups, pine-covered Chilean hills behind, flat bright daylight, eye-level long view, 28mm lens, architectural photography, ultra photorealistic, 8K
