계단식 정원과 캔틸레버식 오피스로 구성된 체코 프라하의 마사리카(Masaryčka) 공공 프로젝트(Construction of Masaryčka completes, Prague, Czechia)

Masaryčka construction works reach level three, Prague, Czech Republic, 28,000㎡ 면적에 조성된 7개 층과 9개 층 규모에 계단식 정원과 공공 광장의 자연스러운 조화

프라하의 마사리카 프로젝트는 계단식 정원과 캔틸레버식 오피스로 구성된 독특한 건물이다. 2023년에 개장하게 될 건물은 28,000㎡ 면적에 7개 층과 9개 층 규모로 동서측으로 이웃하듯 정답게 놓여있다.

자하하디드 아키텍츠가 디자인한 마사리카는 도시를 구성하는 주요 교통허브 내에서 자연스러운 순환 경로를 엮어주는 역할을 한다. 마사리카 건설은 체코 철도 트랙 위에 새로운 공원을 만들고 마사리크 기차역과 북측과 남측 거리 사이에 보행자 경로를 제공하는 디자인이 돋보인다.

수십 년 동안 버려진 장소의 기차역 옆에 위치한 마사리카는 기존 주차장과 연계된 도시의 지하철 네트워크의 입구를 포함하며 프라하 시민을 위한 새로운 공공 광장으로 거듭나게 된다. 광장은 프라하의 바츨라프 하벨 국제공항으로 향하는 공항철도를 이용하는 승객뿐만 아니라 교외와 국내 도시로의 관문 역할을 한다.

마사리카의 날렵한 파사드는 ‘100개 첨탑의 도시’로 잘 알려진 프라하 구시가지의 도시주의와 적절한 관계성을 고려한 디자인이다. 파사드 디자인은 나 플로렌치 거리를 따라 수평적인 흐름과 구시가지 첨탑을 향한 서쪽으로 날렵한 수직적 변형을 고스란히 반영한다.

건물의 에너지 절약형 특징을 결정지어 주는 옥상 정원과 3중 단열 파사드는 최적의 자연채광을 이끌어내며 LEED 플래티넘 인증을 염두에 둔 것이다. 옥상정원과 더불어 나 플로렌치 거리의 가로수를 정비하고 빗물 활용 물순환 시스템, 중수 재활용 등을 통해 조경수를 관리함으로써 물 소비를 줄이고 자연적인 공기정화 기능을 제공한다. 또한 폐열 회수 시스템을 갖춘 고효율 플랜트와 태양광을 통한 재생 에너지, 에너지 소비를 줄이는 스마트 관리 시스템 등도 건물의 지속가능한 디자인에 일조한다. 이처럼 마사리카는 RIBA 2030 기후 챌린지에 의해 수립된 탄소 제로 달성을 위해 현지 공급 업체와 연계해 재활용 자재를 우선적으로 고려해 건설한다.

With its facades now completed, the Masaryčka building in Prague is 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 that 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.

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 city’s rail, tram and bus networks; defining a welcoming gateway to the city for suburban rail passengers as well as those using the express rail link that is currently under-construction to Prague’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.

Targeting LEED Platinum certification, Masaryčka’s incorporates a double-insulated façade that ensures optimal natural light at 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 has 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.

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 to Prague’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.
