A3 Advanced Architecture Apartments

The idea was to create a building which was harmoniously fit in its environment. Two elements set the architectural concept – the mountain and the city. A3 is located in the border area where these two elements overflow into one. Due to its position – in the part of Sofia where the modern and interesting buildings are, A3 is designed to be contextual and innovative. The other dominant component of the environment is the mountain, peeking into the building. The logical result from these elements is the dynamic and modern shape of the building, while its function was never harmed.

Bulgarian architect, Svetoslav Stanislavov, is recognized as one of the most notable figures in the contemporary architecture realm in the country today. In 2012 he founded his own practice, STARH, in the city of Varna, majoring in residential, hospitality and office architecture with wide variety of scale. In 2020 the studio has expanded by opening an office in Sofia as well. In this short time since its founding, STARH, has created an impressive portfolio of completed projects in the country, having recognizable quality in design. The studio has succeeded to positively affect the context with their work. The formula that they use is always striving for balance between aesthetics, functionality and quality in architecture that will last in time. Stepping out from the design comfort zone and experimenting with innovative materials is part of their character. Following these principles, major projects of the studio were born: A3 Advanced Architecture Apartments (2017), Varna Wave (2018), K Residence (2018), BGA Corporate Building (2019), B73 (2021). In recent years, their firm conviction led them to an international acclaim as well. STARH is a laureate in Architecture MasterPrize, Architizer A+ Award, IDA Design Awards, A' Design Awards, BigSEE. In 2018, 2020 and 2022 STARH was nominated for Building of the Year by ArchDaily.


STARH was created with a devotion to a cause, which benefits the society and brings the architects’ inner satisfaction. The studio has taken the mission to break through stereotypes with a fresh, different and bold approach, expressed in strong and determined forms. The architects at STARH believe that the limits could be overcome with a spirit of creativity, innovation and a sense of aesthetics. Their work covers the spectrum of major architectural challenges - from small, fine architectural edifices for private clients to large public projects. By welcoming them in new ways, putting feeling and enjoying every step of the process, they believe that they change and create new dimensions in the environment we inhabit.
