Text description provided by the architects.The Masaryčka building inPragueis defined by circulation routes which will provide access to new civic spaces for the city. Accommodating the continued growth of the city’s corporate sector with office spaces designed to meet 21st-century working patterns, the 28,000 sq. m Masaryčka office and retail development incorporates seven storeys within its eastern section and nine storeys at its western end. Integrating with Czech Railways’ modernisation of the historic Masaryk Railway Station is creating a new public square partially over the railway tracks, Masaryčka’s design will enhance accessibility to the railway platforms below and provide new pedestrian routes between Florenc and Hybernská on either side of the station.Targeting LEED Platinum certification, Masaryčka’s incorporates a double-insulated façade that ensures optimal natural light in all work areas and communal spaces. A cascade of terraces divides the two buildings while similar terracing on the eastern façade gives every office floor direct access to generous outdoor spaces. Communal roof gardens offer panoramic views across the city. Hybrid ventilation is supported by a high-efficiency plant with waste heat recovery systems while the building’s smart management systems continually monitor and adjust environmental controls to reduce energy consumption.Planting using local species of plants, shrubs and trees irrigated by Masaryčka’s rainwater collection system, including the transformation of Na Florenci into a tree-lined avenue, will provide cooling summer shade and natural air purification. Low-flow systems and grey-water recycling will further reduce the centre’s water consumption. Masaryčka’s construction and procurement have prioritised local suppliers and materials with a high recycled content to meet the 2025 targets for embodied & operational carbon established by the RIBA 2030 Climate Challenge.Bordered by Masaryk Station’s railway platforms to the south, Na Florenci Street to the north, and the Wilsonova elevated freeway to the east, Masaryčka has been constructed on a derelict site that has stood abandoned for several decades. To the west, Masaryčka replaces the existing car park on Havlíčkova Boulevard with a new public square with interchanges between the city’s rail, tram and bus networks; defining a welcoming gateway to the city for suburban and domestic rail passengers as well as those using the express rail link that is currently under-construction toPrague’s international airport. Located one kilometre east of the city centre’s Staroměstské Square, Masaryčka’s design establishes a dialogue with the architecture and urbanism of Prague’s Old Town – known as ‘the golden city of 100 spires’. External fins within Masaryčka’s façade contribute to solar shading in the summer and transform the project’s horizontal composition to the verticality of its western façade facing the spires of the Old Town.Due for completion in 2026, Czech Railways’ renovation of Masaryk Railway Station adjacent to Masaryčka retains the existing historic terminus building and includes the construction of the new public square partially over the tracks giving access to individual platforms and a direct transfer toPrague’s metro line B. Transforming the station into a fully accessible, multi-modal transport hub for the city, its modernisation programme extends the current number of tracks from seven to nine and reconstructs all platforms, overhead line equipment and power supply.
