The project is located in one of the most desirable neighborhoods of Isfahan – south of Nazar street – just a short distance from the Zayandehrood river park. In the interior design of the complex it was attempted that none of these units would be alike. The upper floor northern unit is designed as a duplex to take advantage of the beautiful scenery of the riverfront park. The unit consists of 4 bedrooms, 3 bathrooms, and a separate living and study area. Creating alcoves, fountains, and greenery on the rooftop alongside the views to the riverside park will provide residents with a pleasant atmosphere for relaxing and spending the evening. The purpose of the interior design is to improve the physical and psychological performance of the space to make life comfortable. Architectural space without interior design either can not be used at all or will not be optimized if it is usable.
