The outer frame, column and cornice of the main building are all designed with oblique section.The horizontal lines of the floor line intersect with the inclined planes between the columns, which increases the requirement for construction accuracy.

The square main building is surrounded by water on three sides, and the columns of the outer frame fall on the water.The column above the water surface part of the exterior aluminum plate, the water surface below the part of the outer uniform width of the stainless steel plate.The transition position of stainless steel and aluminum plate is just 10mm above the water surface, which can not only create the visual effect of the column falling into the water, but also bring the change of light and shadow by the reflection of the stainless steel plate when there are ripples on the water surface.

At the junction of the bottom of the external wall and the water, the edge line of the inverted triangle is designed to lift the main building lightly, creating a visual effect of floating on the water.The edge line is 80mm higher than the water surface, and the top position is flush with the steel groove at the bottom of the glass surface of the outer wall, and is flush with the interior, so as to realize the pure connection of the glass surface directly falling on the ground.
Facade design follows the most pure architectural generation logic of "line, combining surface and forming body" : use strong columns and cornice lines to outline the straight architectural outline;Use soft metal texture and transparent glass surface to weave delicate skin;Lines and faces enclose a compact and powerful geometry.

Through the contrast of rigid and soft, virtual and real, the modern tension of architecture is demonstrated.
The metal lines that make up the building outline are all customized products: from large columns, cornice, waist line and bottom edge, to small door cover and column base detail modeling.The customized metal profile is highly consistent with the strength and simple beauty pursued by the design. Through the detailed design of the interface, the designer pays attention to the user's activity experience and the builder's exquisite construction technology.

A large number of unconventional oversized panels are used for the suspended ceiling, which is exactly corresponding to the glass partition of the facade, reflecting the continuity of the design in details.The aluminum plate of the ceiling under the semi-outdoor space of the inner courtyard is 3m long and 2.3m wide at most, and 30mm stainless steel bars are embedded between the plates.Super large plate presents a challenge to the flatness of construction. By using 3mm thick plate and increasing the density of steel keel, after several adjustments of on-site installation, the overall flatness effect is finally presented.

The inner courtyard space is intended to create a spiritual place that can carry various living functions such as transportation, communication and rest through the large overhanging roof enclosed on three sides. Therefore, a large and non-daily outer corridor is designed. The overhanging eaves of the outer corridor are 5.1m deep and 3.9m high.Large overhanging eaves are designed with two levels, namely, flat roof suspended ceiling and slope roof suspended surface, so as to meet the spatial feeling of the approachable scale.The hanging roof of the inner flat roof is flat with the indoor, weakening the boundary between indoor and outdoor. The height of the eaves of the hanging roof of the outer slope roof is 3.6m, providing a viewfinder frame for the indoor landscape of the inner courtyard.

The inner slope roof adopts the vertical edge occlusion metal roof system, the vertical edge height is only 25mm, the vertical edge at the end of the cornice is processed by workers on the spot into bevel Angle, so that the edge is flat, emphasizing the sense of line.
