The architecture studio Buerger Katsota Architects has designed an office building in Neo Psychiko, Athens, Greece, located along Kifissias Avenue—one of the city’s main thoroughfares.

Its architecture seeks to establish a visual connection with the green landscape of Psychiko, while creating a bright and comfortable work environment that explores the interplay between openness and solidity, transparency and opacity.     

The building, designed by Buerger Katsota Architects, is articulated through two volumes: one solid, facing south, and another open and glazed, facing north. The program is distributed across four floors dedicated to offices, a ground floor for commercial use, and two underground levels. The project incorporates a landscaped garden on the ground floor and a green roof designed as a space for rest and social interaction.

In terms of construction, the building combines an exposed concrete structure with a glazed envelope composed of frameless glass panels and reflective fins set at various angles. Inside, slender steel columns—discreetly positioned behind the glass facade—create the impression of a suspended volume.

Project description by Buerger Katsota Architects

The office building is located in Neo Psychiko, prominently positioned along the major axis of Kifissias Avenue, a key thoroughfare in Athens. This contemporary structure encompasses four floors dedicated to office spaces, a ground floor designed for commercial use, two spacious basements, and a carefully landscaped roof garden. The building's design not only aims to provide functional and aesthetically pleasing workspaces but also integrates elements that promote sustainability and ecological consciousness.

The never-ending flow of Kifisias Avenue, a major north south axis of metropolitan Athens, is approached like a natural stream of movements, lights, vehicles and daily passersby. The building responds to this quality though a solid exposed concrete volume to the south, and an open glazed volume to the streetside north. A distinct feature of the building's exterior is the use of frameless glass panels for the facade. This design choice creates a seamless visual connection between the interior and exterior spaces, fostering a sense of openness and continuity. The transparent nature of the glass panels allows ample natural light to flood the interior spaces, creating a bright and inviting atmosphere for the building's occupants. The vastly open floor plate overlooks the riverlike adjacency of endless movement. During the day the building appears as a crystalline structure through its multi-angled reflective glass fins mirroring the green garden city suburb of Psychiko opposite, at night adding to the illusions of light and reflections to this technical nature.

Inside the building, from the ground floor to the roof, thin steel columns discreetly positioned behind the glass facade contribute to the overall aesthetic by giving the impression of the office building as a floating volume. These structural elements are designed to be minimally intrusive, enhancing the feeling of lightness and transparency. The innovative use of materials and design techniques in this project not only meets the functional needs of a modern office building but also creates an environment that promotes well-being and productivity for its users.

The architectural scheme focuses on creating an ecofriendly and modern office environment within the bustling urban landscape of Athens. A significant aspect of the project design is the incorporation of extensive planting on the ground floor featuring a landscaped garden, offering a tranquil retreat amidst the city's bus. Additionally, the planted roof garden serves as a serene space for relaxation and social interaction, enhancing the overall appeal of the building.
