The Design

About Urawa Garden Bldg Edificio de Oficinas

O Urawa Garden Building é un edificio de oficinas en Urawa, Saitama, Xapón. Un paso peonil atravesa o terreo e conecta as rúas circundantes, evocando a antiga rúa comercial Nakaginza Seven. As prazas abertas ao longo do paso ofrecen aos peóns e aos traballadores das oficinas lugares para encontrarse. A fachada incorpora cubos de vidro flotantes con distintos graos de transparencia, de modo que a aparencia cambia coa luz do día. Nos espazos de traballo interiores empréganse materiais naturais, vexetación e arte. A iluminación de baixo consumo enerxético e as estratexias de deseño pasivo favorecen o confort e a sustentabilidade.

Tags: architecture, office, urban design, passage, glass facade, sustainability
Production Technology: The facade integrates glass panels with varying transparency, reflecting urban layers dynamically. Natural materials harmonize with the surroundings, creating a warm and inviting office space. An energy-efficient lighting scheme and passive design strategies enhance sustainability and comfort, ensuring an environmentally responsible and user-friendly work environment.
Design Challenge: The primary challenge was balancing commercial functions with public accessibility. By strategically placing the through passage and open plazas, the project strengthened the connection between office spaces and the urban fabric. The floating glass cubes required innovative lightweight structures and varied transparency to seamlessly integrate the architecture with the cityscape.
Research: Type of Research: Urban architectural design
Objective: Exploring the potential of offices integrating commercial and public space
Methodology: Analysis of historical urban transitions, urban-scale simulations
Data Collection: Pedestrian movement observations, visual simulations
Results: Creation of an urban-office hybrid through passageways and plazas
Impact: Enhancing pedestrian networks and establishing a new urban icon
Inspiration: The design draws inspiration from the site’s historical layers, reinterpreting Edo-period urban structures and the postwar vibrancy of local shopping streets. The building reconstructs past pedestrian flows, creating an open urban space. The floating glass cubes symbolize the lights and energy of the former market, establishing a new architectural landmark that bridges tradition and contemporary urban life.
Project Duration: The project is located in Urawa, Saitama, Japan, and was completed in February 2024.
Operation Flow: The through passage seamlessly connects the building to the city, allowing both office workers and pedestrians to interact fluidly. Open plazas enhance community engagement, providing diverse activity spaces. The glass cubes on the facade capture light dynamically, shifting appearances throughout the day and reinforcing the building’s urban presence.
