Shinonome Shinkin Bank in Maebashi: A Renovation that Redefines Urban Banking Spaces

Preserving History Through Modern Renovation

The Shinonome Shinkin Bank in Maebashi, redesigned by HAGISO and twism design studio, is a striking example of how architecture can blend preservation and innovation. Originally built in 1964 during the Tokyo Olympics era, the structure served as the Maebashi Shinkin Bank headquarters. Decades later, the building underwent a transformative renovation in 2022, proving that thoughtful design can rejuvenate existing structures into vibrant, functional spaces.

From Reconstruction to Renovation: A Sustainable Approach

Assessing Earthquake Resistance

In 2015, an earthquake resistance assessment flagged potential structural vulnerabilities. Initially, the plan was to demolish and rebuild. However, upon inspection by structural engineers, it was determined that the building could meet modern standards with appropriate retrofitting. This decision not only preserved the historic steel-reinforced concrete structure but also aligned with sustainable design principles by minimizing waste.

Embracing Adaptive Reuse

Renovation became the chosen path, allowing the project to retain its original architectural character while introducing contemporary design elements. This approach highlights the bank's commitment to sustainability, a cornerstone of the renovation.

Enhancing Community Connectivity

Creating a Vibrant Plaza

A key feature of the renovation was the introduction of a central plaza, designed as a "relay point" for the community. This space connects the bank with the relocated FM Gunma building, fostering synergy between these two key institutions.

The plaza is paved with locally inspired brick tiles and surrounded by tall trees and planting strips, providing shade and creating a natural cooling effect in Maebashi's hot summers. Elevated wooden decks add layers of visual interest and functionality, offering places for rest and social interaction.

Reorienting the Building Facades

The building's design reimagines urban connectivity. By repositioning the primary entrance and making the south and west sides active facades, the architects created a seamless connection between the building, the plaza, and the surrounding streets. This redesign maximizes pedestrian engagement and transforms the once-neglected rear areas into lively, accessible spaces.

Interior Innovations: Blurring the Lines Between Inside and Outside

Integrating Indoor and Outdoor Spaces

The first and second floors of the building are interconnected, forming a central space that embodies the core of the bank's new design philosophy. The lobby, treated as a semi-exterior space, features planting strips, streetlights, and a coffee stall. This continuity between indoor and outdoor areas is further emphasized by the consistent use of brick tiles across both spaces.

Public Spaces for Community Use

The second floor houses a public library accessible beyond banking hours, making the space a cultural hub. This community-centric feature aligns with the bank's vision of creating a welcoming environment that serves more than financial needs.

Revitalizing Existing Spaces

The Conference Room Transformation

The third-floor conference room underwent a remarkable transformation. Once a low-ceilinged administrative office, it was restored to its original double-height form. Large windows were added to provide sweeping views of the surrounding tree canopy, connecting users with nature.

Structural Aesthetics

The renovation celebrated the building's original structure by exposing its beams and columns, juxtaposing raw architectural elements with modern finishes. Column-and-beam joints were accentuated with different materials, adding an artistic touch to the interiors.

Architectural Materials and Collaborators

The project utilized high-quality materials and collaborated with renowned manufacturers like AICA CINERGY, ECOROCA, and Karimoku New Standard, ensuring durability and aesthetic appeal. Brick tiles, a unifying element, were chosen to reflect Maebashi's architectural language and to harmonize with the surrounding urban fabric.

Biophilic Design and Urban Sustainability

Green Integration

Tall trees and lush greenery, combined with irregularly shaped planting strips, define the plaza's biophilic character. These elements not only enhance the plaza’s aesthetic appeal but also improve its environmental impact by providing natural cooling and fostering biodiversity.

Sustainable Urban Design

The renovation demonstrates how architecture can support urban sustainability by integrating natural elements, reusing existing structures, and promoting community interaction.
