Map Location

A prestigious development in the heart of Prague

This project provides seven floors of prestigious office space, three levels of flagship retail and two basement levels of parking at a landmark corner site on Wenceslas Square.

Sensitive design in a historic setting

The building was designed and developed very carefully to respect the urban, historical and social significance of this prominent location. The building is located in the heart of the city centre on the corner of two streets highly frequented by pedestrian traffic and in close proximity to several modes of public transport, including the metro (lines B and C) and trams (served by 9 lines as well as night-time services). Also, the main railway station is just a 500m (a 6 minute) walk from the office entrance.

Chapman Taylor’s Prague studio was the architect for this highly sustainable office and retail development

Environmentally sustainable

The building has charging points for 56 EVs in the basement car park and the first basement also includes a service yard to ensure all deliveries made are off-street. The service yard provides access to the retail and office components as well as servicing of the adjacent 4* hotel, owned by the same investor.

The high-performance 3D façade brings a unique identity to the square

The high-performance building envelope is designed to minimise year-round energy demands. All windows are triple-glazed for thermal and acoustic reasons, with a double skin façade system used on the feature curved corner “tower” to maximise the performance of this zone, which faces south onto the noisiest part of the street. Parametrically controlled external blinds (with manual override) minimise solar gains and internal blinds provide effective glare control to all workplaces.

Zero CO2 emissions on site

The development is highly energy-efficient, incorporating intelligent, fully-integrated building technical systems. The building has zero on-site C02 emissions in operation, with air-source heat pumps providing heating and cooling to a VRV based HVAC system that effectively balances heating and cooling demands within the building. Indoor air quality is carefully monitored and excellent levels of daylighting ensure that the use of artificial lighting is minimised. All the main technical equipment is located within the volume, keeping the roofscape free of mechanical plant.

Careful materials selections

The main interior spaces and the façade incorporate differently worked versions of the locally-sourced travertine stone from Špiš region of Slovakia. All other interior materials are selected for their durability and ease of maintenance.

Creating a user-focused community

A community space on the top floor is available for all building users and includes an extensive roof terrace providing stunning views over the historic city skyline. The Flow Zone lounge bar and restaurant are available all day for building users, including for healthy lunches each weekday, and can also be hired for company and social events in the evenings. The roof terrace also hosts regular yoga, Wim Hof ice-bath events and other health-promoting activities.

BREEAM certification

The Flow Building has achieved two BREEAM Outstanding certificates, for the office and the retail components, under the BREEAM International New Construction 2016 scheme.

The Flow Building was the first in the Czech Republic to achieve a BREEAM Outstanding rating, the highest BREEAM rating under the latest version of the BREEAM International New Construction scheme.
