Sitnyakovo Boulevard

Serdika Offices is a modern Class A office development designed to meet the highest standards of sustainability, functionality, and tenant comfort. Located in the prestigious Oborishte district in Sofia, the building offers a high-quality working environment that combines smart design, advanced technologies, and excellent accessibility, making it an ideal choice for leading international businesses.

The office building rises eight floors above Serdika Center and comprises a total leasable office area of 28,500 sqm, distributed between levels 3 and 10. Typical floorplates of up to 4,000 sqm are intelligently divided into flexible office units of 250 and 500 sqm, which can be easily combined or reduced without the need for adjustments to ventilation, air conditioning, electrical systems, or cabling. This modular concept allows tenants to adapt their space as their business evolves. The clear ceiling height of 3 meters and the 14-meter distance between façades ensure a feeling of openness and excellent natural daylight throughout all office areas.

Serdika Offices is a certified green office building and a benchmark for sustainable development. Environmental responsibility is an integral part of both the building’s design and its ongoing operation. The project holds DGNB Platinum certification, the highest possible grade under the German standard for sustainable construction, as well as BREEAM In-Use Excellent certification. It has received international recognition for its green performance and operates entirely on electricity from renewable energy sources. Additional initiatives include separate waste collection, recycling, landscaping, support for green mobility, bicycle and scooter parking, electric vehicle charging stations, and dedicated zones for shared electric cars. The building is also certified as a COVID-19 safe work environment.

The building is designed to ensure maximum comfort through advanced technical systems. It features a four-pipe air conditioning system with individual temperature control, a fresh air ventilation system providing air exchange twice per hour, and openable windows on both sides of each window. A double-glazed façade enhances thermal efficiency and enables safe natural ventilation, while automated external blinds adjust according to the movement of the sun. Raised floors allow integrated wiring and operational flexibility, and LED lighting is used throughout the common areas. Safety and reliability are ensured through a fire alarm and sprinkler system, two independent power substations, a diesel generator for uninterrupted operation, and an integrated building management system.

Access and circulation within Serdika Offices are carefully planned for efficiency and convenience. The main reception is located on level +3 and is accessed by panoramic elevators from the main entrance on Sitnyakovo Boulevard, as well as through the atrium from the parking levels. The offices are arranged around two spacious atriums and are served by twelve high-speed elevators distributed across six separate lobbies, minimizing congestion. Elevators connect the office areas directly with the parking levels and the adjacent retail areas. Parking is available within a shared facility offering more than 1,600 spaces on three levels, two of which are underground, with an excellent parking ratio of one space per 50 sqm of leased office area.

The location of Serdika Offices provides outstanding connectivity in one of Sofia’s most attractive urban districts. The building offers easy pedestrian access, convenient routes for cyclists and scooter users, and quick access by car. Public transport connections include multiple tram, bus, and shuttle lines, as well as a metro station within walking distance, with an additional metro stop currently under construction nearby. This central location allows tenants and visitors to reach the building easily from all parts of the city.

Tenants benefit from a wide range of on-site amenities that support productivity and work-life balance. These include a modern fitness facility, a rooftop café located in an open-air atrium, and direct internal access to a major shopping and lifestyle destination with a broad selection of shops, restaurants, cafés, banks, and everyday services. The building offers 24/7 access, round-the-clock security, CCTV surveillance in common areas and elevator lobbies, and controlled access by card systems at entrances and in elevators.
