The Pump Sluice Station on Nangupu River, at the junction of the inland river between Jiangsu Province and Shanghai, is an important control project in the polder area in terms of flood prevention, water logging control, water resource scheduling and planning in Anting area. The control house for the station consists of four parts: pump and sluice electromechanical devices, equipment control, office administration and logistics. The site is located at the southwestern side of pump and sluice main body and covering a long and narrow area，in the greenbelt of the south river bank, on the south side adjacent to the newly established kindergarten over the road; As the eastern area is reserved for a crossing bridge, the entire site is 1.6m lower than the urban road in the outer side of the pedestrian entrance at the southeastern corner of the site. At the very beginning of design, designers have put our focus on considering how to make use of architectural operation to establish its inner compactness for the infrastructure supporting project on this banal and confined site，to bring positive impact on the river interfered by this giant concrete pump and sluice facility and its surrounding waterfront area.

Designers firstly made space configuration according to the site conditions to realize its program. It is divided into two groups of two-story massing that is paralleled with the river and staggered back and forth.
The ground floor along the river in the north is set with high and low voltage distribution room, a hydraulic room and other electromechanical devices and the upper floor is set with an equipment control room, a station master room and a meeting room; in the south，the ground floor at the back of the river is set with a duty room, a canteen and other logistics rooms for machine maintenance and warehousing. The upper floor is set with reception rooms and various administration offices. The reason for this kind of space configuration is to keep those spaces without long-term stay of staff such as electromechanical devices and logistics in the ground floor and those spaces with residing staff such as equipment control and office administration in the second floor. This configurational differentiation for both lower and upper floors is also the logic implemented for space shaping. It is mainly contributed to our discussion about the relationship among structure, tectonics，space atmosphere and site specificity. Designers adapt wooden template cast-in-site concrete shear wall structures and lightweight steel constructions which differ from each other greatly in weight and fineness senses to the different program on the lower and upper floor. The electromechanical and logistics space on the ground floor is designed as some relatively closed concrete boxes, with the inner and outer wall and flattop displaying distinct and rough wooden patterns of 30 cm loose wooden templates, leaving only necessary door and window openings.

The second floor is confined by two concrete U-shape groove structures protruding from the substrate of the ground floor. The upper part of them is tied by steel girders, and rooms are organized into six lightweight steel construction boxes of different sizes with whose surface made of corrugated aluminum sheets and then respectively put into the two U-shape grooves. Every two boxes are isolated by a patio. Together with the clearance between some boxes and U-shape groove side wall and the terraces at the two ends of the U-shape groove, second floor is shaped a penetrated, relaxed and comfortable space.

With regard to the relationship among structure, tectonics and space, designers have also fully integrated the site context and circulation so as to enhance spatial experience. The staggered massing forms an entrance front area and a overhang sight viewing terrace respectively in the road intersection at the southeastern corner and the area along the river at the northwestern corner.

All the straight run stairs are placed in the clearance between the southern and northern massing, so that people can always have a feeling of shuttling freely on both inside or between the two volumes.The entrance into the control and management area is set on the second floor. It is possible to get access to the small lobby on the east end of southern massing from the platform where people can reach by taking open air stairs at the entrance front area.
As the ground floor story height for electromechanical space is much higher than the logistics space, a 3m high staggered space is naturally formed between the southern and northern parts on the second floor. Starting from the southern part lobby, passing through its corridor and another straight runs stair, people are oriented to a glass roof space traversing the northern massing and crossing the clearance between the southern and northern parts. This glass roof space is actually a foyer between station master room and control room, from which people can overlook the partly high ceiling lobby.

The application of materials inherits the logic on structure and tectonics by shaping the space in a comparative but compact way. The super wide 30 cm and 40 cm thick carbonized pine templates are the key material in the bare concrete process of this project, which attaches clear wooden patterns with a reliefs feeling to the concrete surface and endows the bare concrete with natural and rough surface. This atmosphere is further emphasized by the irregular openings at the side walls of the second-level U-shape groove.

Meanwhile the concrete visual weight is balanced in some degree by the entire polished stainless steel sheet on the eastern gable wall facing the entrance front area, and on the corridor side wall between canteen and machine maintenance room on the southern part ground floor, and the silver gray corrugated aluminum plate light box inside the second-floor U-shape groove.
