The project involves the addition of a four-storey residential structure above a preserved neoclassical ground-floor building in Pagrati. The original structure is a single-storey residence dating from the 1910s, which will be retained and restored. The ground floor is intended to function as an office space. The new construction will comprise four fully independent floor-through apartments, designed for short-term rental. The architectural approach focuses on clean lines, efficient layouts, and optimal orientation with views toward the Acropolis. Particular attention is given to the integration of the new volume with the existing structure, both aesthetically and structurally. The project is being designed and will be realized by architect-engineer Takis Proios, founder of the architecture office Proios Office. The project is located in Pagrati, on elevated ground near the Panathenaic Stadium, facing the pedestrian street of Ivikou. Its position within a dense urban block and along a public front dictated key aspects of the architectural approach. The design process began with the precise documentation of the existing neoclassical ground-floor building, which is officially listed as preserved. The façade, with its distinct historical features, served as the primary reference for the new composition.
