Office Building Kotelna Park II in Prague

System solutions by heroal used for office complex in Prague

One of the most dynamic, vibrant business districts of the booming city of Prague currently evolves in the city’s district 5. Architectural highlight: Even the most state-of-the-art office buildings are carefully integrated into the existing surroundings. For example, the office building Kotelna Park II, designed by the award-winning architects Chapman Taylor, successfully takes up the design of its sister complex Kotelna Park I completed in 2019 and built as a further re-development of the traditional Waltrovka Factory. One of heroal’s customers, the Czech company RETRE, s.r.o., saw to the implementation of the building plans.

Office building with convenient extras

By spring 2020, 12.000 m² of office space with a view and a vision have been built. In the reception area located on the spacious ground floor of Kotelna Park II, visitors may be welcomed around the clock. A café is also to be found here, inviting visitors and occupants to stay.

In a nutshell, this complex is open to modern concepts of work and thus represents the office of tomorrow.

Coherent master plan with system solutions by heroal

This building with its futuristic appearance was expected to closely combine technology and the eco-friendly exploitation of resources. Sustainability plays a predominant role for the building concept. In addition, another focus was placed on light and flexibility inside. The ideal combination of these two objectives can also be seen outside. All floors of Kotelna Park II have been designed with a circumferential curtain wall with large windows. Each floor has its own 20 m² terrace. The parking levels have green roofs creating a terraced podium. A rear garden offers a landscaped space which can be used by all occupants of the building.

The building plans of Kotelna Park II provided for a total space of 770 m² for windows and 3,400 m² for curtain walls, offering an unobstructed view of the city of Prague. The developer chose window, door and curtain wall systems made by heroal.

Windows, doors and ventilation with a concept

The window system heroal W 72 was the system of choice. It perfectly meets the demands on this unparalleled urban office building – because it is innovative, sustainable, cost-effective and energy-efficient. The curtain wall was supplemented by ventilation flaps heroal W 72 VF, which offer numerous advantages. All ventilation flaps can be opened and closed independent of users, which makes possible a controlled, natural ventilation around the clock. Just as required by the customer, they harmoniously integrate into the curtain wall, emphasizing the individual character by setting visual accentuations. The system solutions are rounded off by the project door system heroal D 72, which stands out in the highly frequented entrance area of Kotelna Park II.

Curtain wall offering additional advantages

A dream come true for planners, builder-owners and partners: A curtain wall with uncomprisingly efficient energy values and flexible design options. The curtain wall system heroal C 50 HI achieves excellent values for ventilation, thermal insulation and tightness, which is a most important aspect for an office building of this size. The curtain wall system by heroal leaves much freedom for individual design options. The special feature: the post-transom curtain wall is designed with a radius, so that it is slightly curved. The ventilation flaps heroal W 72 VF with their wooden look set a visual accentuation in the curtain wall of Kotelna Park II – made possible by the coating technology heroal Surface Design (SD). This feature lends individuality to this harmoniously designed curtain wall.
