The residential unit is located in a building belonging to an old building, at “Bratstva Jedinstva” street in Podgorica. The found condition did not meet the standards of the modern way of life, nor did the approach to interior decoration, so it was necessary to carry out the necessary adaptation measures. By analyzing the structural elements, the existing condition was defined, and by the adaptation and interior design project, the necessary interventions were foreseen for a better functional organization. The result is a modern, functional space with plenty of natural light. By using light tones and reflective surfaces, during movement through the apartment, the segments are seen from different angles, and thus the complete space becomes a unique dynamic structure.
