Capital Fort Business Center is a Class A office building in Sofia. It is the tallest building in Bulgaria. It has 28 floors and a surface area of 80,000 square metres (860,000 sq ft). The building has two underground floors which serve as parking spaces for around 750 cars.[1] Other source [2] points out an architectural height of 126 m, but a roof height of 110 m, also 27 floors instead of 28.

Design and construction[edit]

The Concept Design of Capital Fort is done by WKK[citation needed] whilst working at Atkins. The local architect of record is "A&A Architects", Sofia, Bulgaria, who have worked on most of the Business Park Sofia buildings. Atkins is the architecture company behind Burj Al Arab in Dubai and as a result Capital Fort shares most of the external looks with its distinctive predecessor (itself completed in 1999). Capital Fort is developed by Fort Noks, the company behind 500 000 m² built-up area of Black Sea resort developments in the last decade.[3] Construction began on 29.01.2010 and building was topped out by 2012. Estimated value was between 60 and 80 million.


This mixed use building (Office, Retail & Conference Facility) comprises a high-rise office building and a L-shaped low-rise office building that both sit over a podium, which houses a wide range of retail and conference facilities, accessed through a grand atrium lobby.[4] Offices use 24 of building's floors. Superior equipment and installations include 12 high-speed lifts in the high body, advanced HVAC technology and a building management system, covering climate control, security, fire protection and safety.[3]

Class A[edit]

Building Owners and Managers Association (BOMA) defines three categories of office buildings - namely Class A, Class B, and Class C. Since the number of parking spaces is 717,[3] Capital Fort does not cover the standard for a Class A office building.[5] Requirement is a parking space for each 100 m² of gross floor area (GFA) [6] The gross floor area of the building is 80 795 m²,[4] which requires 808 parking spaces for Class A - 91 more than the currently available ones. Other source[3] points out just 40 000 m² of (probable) GFA, since "efficient open-space" of 1 150 m² a floor (cited there as well) gives a total of 32 200 m², in which case Capital Fort covers Class A requirements, regarding parking spaces. The building is not purely an office one, having retail and conference functions as well.
