The completely renewed and centrally located Fabian 21 will offer versatile services and modern premises that are suitable for a head office as well as hybrid work.

The building was completely renovated and in connection with the renovation, the main entrance moved from Unioninkatu to Fabianinkatu 21, where an elegant and impressive lobby was completed.

The renewed facilities offer a working environment that supports your staff’s wellbeing. Depending on your needs, the space can be arranged into offices of approximately 200–3,000 square metres.

Fabian 21 is located in the heart of the Kaartinkaupunki business centre. This property is close to the sea-front, parks and the Old Market Hall as well as the area's boutique hotels and premium restaurants. There is also a large grocery store and a post office in Kasarmitori Square. State-of-the-art facilities in an idyllic neighbourhood with a sophisticated but relaxed atmosphere. Kaartinkaupunki is a charming mix of old and new. A peaceful place in the centre of Helsinki.
