Symbiosis Cat House Residential Building

Architecture, Building and Structure Design Symbiosis Cat House Residential Building by Happystudio Symbiosis Cat House is a residential building designed for a narrow urban site. The four floor house allows people with allergies and cats to live together. A vertical zoning strategy separates animal areas from human areas. A central atrium drives a passive stack effect that removes allergens without heavy mechanical systems. Dedicated exhaust units serve the litter zones. Uncoated concrete, fair faced brickwork and perforated metal treads limit dust and chemical emissions. A cat tower rises beside the stairs, keeping the household visually connected.
