line+ studio completes the riverside 'mountain house' factory in china

in the chinese city of haining, line+ studio has completed the renovation of ‘zhejiang perfect production factory’. situated next to the estuary of qiantang river, the industrial park has been redesigned around a simple landscape of courtyards, connecting volumes, and streamlined circulation.

after in-depth analysis of both the site and the production process requirements, line+ studio decided to focus on ‘streamlining’ the complex. to streamline the industrial production process and also the life of industrial workers and managers who will live and work there. from the consideration of production-based logistics, the architect extruded the four buildings along the edge of the site to maximum extent, and connected them via the perimeter circular driveway to achieve efficient access, thus forming an inner courtyard that returns to life in the remaining space of the center site.

adjacent to the road, external service workshop is arranged on the east side. the basic production workshop is arranged on the north side and adjacent to the subsequent phase II land. dust free workshop and laboratory are arranged along the spillway on the west side. the landscape interface facing the qiantang river on the south side is used for building r&d office and living supporting complex building. the fifth group of volumes – dining hall and life service center are arranged in the center of the site as the convergence node of life behavior streamline.

this layout forms a central and radioactive functional organization structure that provides the most efficient path connection for workers’ daily production work and after-work life. after sorting out the bottom logic of the efficiency of the park, a spatial composition about restriction and enclosure has been presented. with the natural landscape as the center, there is a certain closed inward space, which also establishes a sense of security, shelter and identity of the living environment psychologically.

the architect selected the workshop evacuation stairs, maintenance pack-way of rooftop solar panels, the paths cross the pool, the indoor stair of trail, and indoor stairs of office buildings, covered them in a uniform weathering steel, and made them either visible or sunken. auxiliary circulation lines of evacuation stairs and walkways are arranged outside the functional block of the workshop, making the redistribution of internal space more free. the corridor and stairs hanging from the wall provide a convenient path for workers to the canteen and lodging house as well as a place for workers to take short breaks. the stairs on the roof provide convenience for the maintenance of the solar panels at the top, as well as outdoor activity space for workers to climb high and look far away.

facing the bank of qiantang river, the scenery around the project is often of the same color as the sky and the water. white corrugated steel plate and ultra-white u glass are selected as the main materials for the exterior wall. while being integrated into the big scene, the two strongly contrasting materials create different textures for the outside and inside of the park.

facing the outside, the exterior wall of the building is decorated with white corrugated steel plate, and the longitudinal window, corrugated texture and folding roof form the ‘mountain’ of the dry, simple “solid surface” texture. facing the inside of the park, continuous u glass forms a continuous translucent state, and forms a completely different texture in the day and night — cool and gentle in the day but warm and transparent in the night. the building rises against the water in a light manner, reflecting the daily work and activities of the building through the facade.
