Deloitte Office Building in Patra

Dynamic reuse

The early 20th-century multi-storey warehouse in the port of Patras, a listed building, has been restored to its original form. Late additions on the south side were removed, and necessary structural reinforcements were made to accommodate office infrastructure and create a modern working environment.

Existing Shell

The enclosure is characterized by a limited number of rectangular windows and the distinctive preserved ventilation holes of the former warehouses on each level. Internally, the original composite load-bearing structure of concrete, steel, and timber was removed and replaced with a new steel-and-concrete framework. The slab levels were redefined to provide sufficient height in the central zones, with the reused building spanning five above-ground floors.

A square atrium was introduced at the center of the floor plan, extending down to the ground floor. This addition was designed to create new openings, improving natural light and ventilation, which had been insufficient due to the small original windows. Two new internal stairwells ensure safe egress for employees from all floors, while the main stairwell features circular windows that reference the façade’s original ventilation holes.

Spatial Organization

The ground floor features the main entrance with a waiting and lounge area, meeting rooms, and seminar halls. On the first floor, there is a dining area, a kitchen, and office spaces to the south. The three upper floors follow an identical layout, dedicated exclusively to office use. Each floor includes ample restroom facilities, as well as kitchenettes and coffee stands for employees. The offices are designed in an open-plan layout, incorporating distinct yet interconnected collaboration and meeting areas of various types, along with executive offices enclosed by glass partitions.

Material Palette

The design aimed to create a vibrant, refreshing space with colorful accents and intriguing architectural details, fostering a welcoming work environment with a domestic aesthetic. To honor the building’s industrial heritage, exposed electromechanical installations were incorporated, evoking its original character. These elements coexist harmoniously with soft materials such as wood, Neptune seaweed, and colored surfaces, forming a modern and dynamic composition. Combined with the transparency and natural light from the atrium, this approach results in a highly expressive reuse of the listed building, perfectly aligned with the company’s identity.
