About Symbiosis Cat House Bizitegi Eraikina

Symbiosis Cat House hiri-orube estu baterako diseinatutako bizitegi-eraikina da. Lau solairuko etxeak alergiak dituzten pertsonei eta katuei elkarrekin bizitzea ahalbidetzen die. Zonifikazio bertikaleko estrategia batek animalien eremuak eta gizakien eremuak bereizten ditu. Atrio zentral batek tximinia-efektu pasiboa eragiten du, alergenoak kentzen dituena sistema mekaniko astunik gabe. Xede horretarako jarritako erauzketa-unitateek harea-kutxen guneak zerbitzatzen dituzte. Estaldurarik gabeko hormigoiak, adreilu ikusgaiak eta metal zulatuzko mailek hautsa eta emisio kimikoak mugatzen dituzte. Katuentzako dorre bat altxatzen da eskaileren ondoan, etxeko kideak ikusmenez lotuta mantenduz.

The Recognition

About the Zilarrezko Saria A' Design Award

Symbiosis Cat House Bizitegi Eraikina Zilarrezko Saria A' Design Award irabazlea da, goi-mailako, zoragarriak eta liluragarriak diren diseinuei ematen zaien ezohiko aitorpen prestijiotsua.

Unique Properties: This narrow row house utilizes a vertical zoning strategy to resolve the paradox of density and hygiene. Key features include a stepped setback profile to ensure future adaptability against high rise developments and a dual loop circulation system. The house functions as a metabolic organ, employing a central atrium to drive a stack effect that continuously purges allergens. This ensures that the living environment remains clear without reliance on heavy mechanical systems.
Dimensions & Packaging: The building dimensions are Width 5100 mm by Depth 17050 mm by Height 9700 mm. It occupies a site area of 90 square meters with a total floor area of 250 square meters across four floors. Structural components include uncoated concrete, fair faced brickwork, and perforated metal panels. A central vertical atrium provides passive ventilation while localized exhaust systems manage air quality.

Production Technology: The construction employs a low maintenance and hypoallergenic material strategy. Fair faced brickwork with calibrated porosity creates a breathing skin for natural air filtration. Uncoated concrete and perforated metal treads minimize the emission of chemical compounds and prevent the accumulation of dander. Aero acoustic zoning utilizes localized negative pressure at litter zones via dedicated mechanical exhaust to ensure high air quality in human zones.
Design Challenge: The primary challenge was reconciling strict biological isolation with visual intimacy on a narrow site. The design had to anticipate future urban density while ensuring the interior remained breathable. Engineering a passive stack effect to isolate dander without extensive use of HVAC systems was the technical peak. The design balances private health requirements with public aesthetic value, proving that rigorous functional needs can yield a rhythmic living environment.
Research: Applied Architectural Research. Objectives included the optimization of health for multiple species in high density settings. Methodology involved spatial mapping and airflow simulation using CFD modeling tools. Participants included a family with severe allergies and two felines. Results showed a ninety five percent reduction in the spread of allergens via vertical zoning. Insights confirm that health is a spatial mechanism. This creates a replicable and neuro inclusive model.
Inspiration: The project originates from a critical conflict between respiratory health and the need for interspecies companionship in dense urban areas. The objective was to demonstrate that biological well being and domestic life can be integrated through spatial innovation. By scaling the internal volume to match the vertical requirements of felines, a nested system was created to protect the air quality for human inhabitants while ensuring freedom for animals.
Project Duration: The project started in January 2022 in Douliu City Taiwan and finished in 2024 in the same location.
Operation Flow: The house functions through a shared vertical journey. As family members walk up the stairs, cats climb up their own dedicated tower right beside them. Both paths rise in tandem around a central void to ensure constant visual and acoustic proximity. Key moments include watching companions move across the atrium or hearing them through light filters while the air remains fresh. This design succeeds by protecting the health of every inhabitant while keeping the emotional bond of the household intact.
