Sumit Singhal loves modern architecture. He comes from a family of builders who have built more than 20 projects in the last ten years near Delhi in India. He has recently started writing about the architectural projects that catch his imagination. 574-1c Lujiazhi Cultural Coffee Shop in Zhoushan, China by Philippe SAMYN and PARTNERS sprl, architects & engineersMay 7th, 2019 by Sumit Singhal
Article source: Philippe SAMYN and PARTNERS sprl, architects & engineers Zhoushan Harbour The local government of Zhou Shan (East China – an archipelago of islands) confided to Wang Shu the mission to rehabilitate the harbour and industrial area of the Lujiazhi Island into a touristic and cultural area, while protecting the quays and keeping maritime activities as memory of the industrial past of the bay. Turning this into a multinational project of innovative contemporary architecture, Wang Shu involved his 14 fellow laureate architect of the Global Award for Sustainable Architecture 2007 to 2009. Each of the 16 projects focuses on contemporary sustainable architecture.  Image Courtesy © Philippe SAMYN and PARTNERS sprl, architects & engineers

Amongst other characteristics of the site, the activity of the harbour has fostered broad and extensive skills in steel craftsmanship. It is why welded steel plate with traditional ship technology is proposed as main construction element for this project. The existing constructions are vernacular and industrial. Local culture and craftsmanship blossom all over, creating a unique poetic environment. Zhoushan offers a subtropical monsoon climate. The average temperature is around 15.3°C and the annual average rainfall is around 1135 mm.

The wonderful setting of P1 at the entrance of the site and at the base of the luxurious vegetation on the mountain, associated with the climatic situation, inspire a light and contransparent answer providing maximum space for people and gardens and minimum space for the cars. A narrow 6.75 m wide parallelepipedic building stretches out on a length of 9.45 m. It encompasses three floors for the coffee shop and the parking alley at basement level. Continuous balconies run along both main façades, allowing these to be fully open in summer and making the building look like a stack of large terraces. The vertical entrance signal, houses 42 cars, or additional coffee shop rooms, with a view on the harbour.

The canopy is bordered by a public gallery at street front. Due to its increased height the canopy structure is also used for hanging banners, transversally and at regular distance, announcing cultural events of the site. Toilet blocks are located on the east gable of the building, within a band of perfumed bushes running northsouth along the direction of the transversal ventilation.

On the West, the desired vertical shading is provided by the tower in the afternoon. Only horizontal shading is needed during warm season. It is provided by the overall canopy. The wind is coming from the seaside during summer, providing natural draught through the building. The intensity of the breeze is being increased by the favourable day temperature difference between the wooden hill side and the harbour water. This beneficial wind direction ventilates also the parking in the good direction, pulling the exhaust gasses away from the city area towards the hill. Double continuous curtains are foreseen along the balconies, one on their external edge and the other between the columns of the façade. This allows to adjust the degree of air-tightness following the intensity of wind and rain. Impact noise transmission is avoided by a flooring made of two steel plates separated by a 10 mm thick non-burning shock-absorbing resilient mat. In order to temper the internal climate in the winter without the burden of a complete heating installation (a boiler, radiators, distribution pipes, etc.), it is considered to install solar thermal collectors on the roof of the gallery at street front, and of the 4 perpendicular galleries, connected to radiant panels.

It is also therefore proposed to realise every piece of furniture out of ultra-light steel elements reducing the fire load to zero. The structure is composed of an array of slender 10 cm side square steel columns, supporting beams at cyclically variable distances : 2.70 / 1.35 / 5.40 / 5.40 / 1.35 m and so on. The rainwater downpipes are integrated in the columns. The beams are 45 cm high lightweight Warren truss beams placed transversally to the building. Those trusses support smaller Warren trusses running parallel to the façade at 1.35 m centres, who in turn support a thin ribbed steel plate flooring. Bracing is provided at both ends of the building.

The slender columns supporting the street gallery are also braced by two grids of thin tension cables, stretched in both extremity bays. The columns are linked by two horizontal cable truss beams (48.60 m long, 3.00 m wide). Transversal cables link those two beams with the structure of the building. The slender columns in the parking are of 100 mm section only. They are protected from cars at their bottom by means of concentric steel cylinders with a diameter of 400 mm. The foundations are made of textile enclosures filled with gravel. They are completely removable, which makes it possible to completely dismantle the building in the future.
