About Urban Prism Guri

Urban Prism waa guri saddex dabaq ah oo lagu dhisay aag magaalo oo cufan oo ku yaal Tokyo, Japan. Qaab-dhismeedka alwaaxda ah wuxuu daboolayaa dhul-dhis wadar ahaan 127.82 mitir laba jibbaaran, kaas oo ku yaal goob dhan 100.13 mitir laba jibbaaran. Darbiyada xadka iyo iridda waxay sameeyaan aag xajin ah kaas oo iftiinka iyo hawada u soo galiya gudaha guriga. Barxad ayaa fadhiga (living room) ka fidisa dibadda, halka shaashado la hagaajin karo ay xakameeyaan sirdhawrka iyo iftiinka maalinta. Dusha dibadda waxaa lagu dahaadhay siding fiber cement ah oo qaab-qaabaysan, halka gudaha loo dhisay sabuulasho oak ah, bir, iyo galaas. Qaabka farshaxannimada ah wuxuu ka jawaabayaa qawaaniinta dhulka ee ku saabsan dhererka iyo dib-u-dhigga (setback) ee deegaanka.

Unique Properties: Urban Prism balances privacy and openness in a dense urban setting. The design utilizes boundary walls and a gate to create a buffer zone filled with light and air, seamlessly connecting the interior and exterior. Japan’s strict height and setback regulations shaped its refined, sculptural form. A courtyard extends the living space, while adjustable screens regulate privacy and daylight. Black bamboo and upward lighting enhance the entrance, evoking a Japanese aesthetic.

Tags: architecture, house, urban design, natural light, spatial composition, sustainable living
Production Technology: The house employs durable materials suited to urban environments. Textured fiber cement siding accentuates light and shadow interplay, reinforcing depth. The interior harmonizes solid wood, steel, and glass, blending modernity with warmth. Oak flooring enhances the tactile experience. High-performance insulated glass and movable screens optimize daylight, ventilation, and privacy. The exterior cladding ensures longevity, requiring minimal maintenance over time.
Design Challenge: The greatest challenge was balancing privacy and openness within strict urban zoning constraints. Japan’s stringent height and setback regulations required innovative volumetric manipulation to maximize livable space. Socially, the project had to address urban density while maintaining tranquility. Externally, material selection was limited by durability and maintenance concerns. Advanced simulations optimized daylight and airflow, ensuring a harmonious spatial experience.
Research: Type of Research: Architectural design research
Research Objectives: Optimization of urban housing through spatial and environmental adaptability
Methodology: Model testing, daylight and airflow simulations
Data Collection: On-site analysis, material performance tests
Results: Established a refined approach to urban privacy, integrating zoning constraints into design solutions
Inspiration: The project transforms zoning constraints into design potential, integrating privacy, natural light, and spatial expansion. The home’s multi-layered structure fosters an interplay between openness and enclosure, adapting flexibly to its surroundings. Carefully arranged volumes and walls create a dynamic sequence of spaces. The design embraces traditional Japanese elements, reinterpreted through contemporary architectural language to enhance urban living.
Project Duration: The project was completed in 2019 in Tachikawa, Tokyo, Japan.
Operation Flow: Smooth circulation and spatial layering create a dynamic living experience. The atrium channels natural light and air throughout the house, shifting in ambiance with time. Adjustable screens and staggered walls allow residents to control privacy and exposure. The courtyard functions as an outdoor extension of the living room, enhancing spatial fluidity. Black bamboo and illuminated surfaces establish a serene entryway, linking nature with contemporary design.
