Reimagining the Bank’s Role in Architecture

DA Architects have revolutionized the traditional bank branch design with bold geometry at the DSK Bank flagship in Sofia, Bulgaria. Located inside The Mall on Tsarigradsko Shose, this branch features a striking, continuous folded surface in a vibrant olive green. This innovative design runs along the entire length of the bank and functions as a bench, desk, ATM housing, screen bezel, and light fixture, all crafted from the same material. It’s like stepping into an origami masterpiece.

A Dynamic Pilot Project with Innovative Forms

Completed between October 2016 and early 2017, this 270-square-meter space served as the pilot for DSK’s branch redesign. DA Architects won a competition with this concept, proving that their dynamic approach could define an entirely new banking experience. They transformed a typical wall into a multifunctional structure, offering an interactive experience that far exceeds the branch’s compact footprint.

Flipping Traditional Interiors with Avant-garde Design

Traditional bank layouts, which isolate core functions, have been upended here. DA Architects instead moved every functional unit to the periphery, creating an open central space. This clever design reflects modern digital banking demands, leaving archaic security considerations behind. The unique forms of the layout further enhance the functional and aesthetic appeal of the space.

Material Mastery and Intuitive Design

The materials used emphasize both form and function. MDF louvers and stainless steel furniture provide the structure, while the dynamic green strip differentiates solid from upholstered surfaces. This intentional configuration conceals all wiring and services, creating a seamless and purposeful design.

An Elegant Ending

At the back of the branch lies a private consultation room, which features switchable glass walls that offer privacy or transparency at the touch of a button. This subtle, yet effective feature underscores the architects’ skill in combining dramatic design with practical utility, where distinctive geometry plays a crucial role in achieving the overall harmony.
