Located in the North Bund of Hongkou District, Hall of the Sun is a 180,000 square meter commercial hub with an emphasis of nature in the design, including its curvilinear facade and a 3-storey-high biophilic food hall under Shanghai’s largest skylight roof canopy. Informed by the organic architecture, Lukstudio has extended the concept of nature and vitality into the public interior spaces.

▲“洞穴”概念设计的演化过程 design evolution of a conceptual “cave”


The scope includes all the elevator lobbies, elevator interiors, corridors and washrooms from Level B4 to L4. With the design intent of creating artificial “caves” , our enthusiastic team experimented a handful of remarkable proposals with various materiality, layers and forms in the concept stage.


The quest of fulfilling “timeless elegance”, “easy maintenance” and “cost effectiveness” in a circulation space challenged us to turn away from the popular approach of creating narrative and character in a commercial space, perhaps a design habit nurtured by the contemporary fast consumption and social media culture. In this exercise, Lukstudio returns to the basics of architecture, embracing “less is more” to pursue order and balance.

▲三段式石灰岩墙面贯穿空间始终 three bands of limestone tiles run throughout the space

▲墙面肌理变化提升空间韵律 change in wall texture enriches spatial rhythm

▲平纹与槽纹肌理通过铜条衔接 reeded and flat panels are articulated by brass plate


The public areas are distributed near the atrium and the northwest corner of each floor where the washrooms are located. The walls from LG to L2 are lined of vertically arrayed limestones stratified into 3 bands. The texture change between reeded and flat panels is highlighted by brass plate details.

▲一个可以驻足歇息的木亭子 a delicate wooden pavilion for a pause

▲精致有序的木格栅与简洁的石灰岩墙面相映成趣 an orderly wooden screen complements the homogenous limestone wall


At the waiting nook, Lukstudio originally proposed a tea-house inspired wooden pavilion to complement the streamlined cave. We imagined this delicate spot would be treasured by those who needs a pause from the stimulating shopping or working environment.

▲休息区最终采用与整体协调的简约设计 the resting area finally adopts a design that blends into its surrounding

▲西北角公区全景 view of the northwestern public area

▲简约纯净的空间能让人更自觉地维持它的秩序 a pure space cultivates a sense of duty in us to ensure its order

▲空间的活力源自绿植,也源自墙面变换的肌理 green plants and the changing textures give a sense of vitality


After the mock-up phase, a more minimal approach was requested. The final design continues with the homogenous stone backdrop with dancing reeded tiles.

▲广告屏无缝融合在有机的墙面中 advertisement screens integrated seamlessly into organic wall

▲客用门与后勤门采用不同的处理方式 a door for guests vs. a door for back of house

▲铜条衔接上下两段墙面 copper strip detail connecting two bands of walls


The overall soothing ambience is achieved with curvilinear details seamlessly integrating the functional items such as doors, handles, signage and advertisement screens. Cove lighting at the ceiling is also softened by the rounded edge construction.

To better reflect the retail mix of L3-L4 focusing on kids, sports and electronics, a more dynamic and playful cave is envisioned as a surprise. Darker wood veneered wall echoes the effects of limestone, then hidden within a white futuristic cave made of Glass Reinforced Gypsum (GRG) is dotted with potholes of mirrored stainless steel. Super-sized pebble benches of different finishes serve as sculptural seating.

▲借助层叠式设计顺利整合较矮的儿童洗手台 the stacking method allows smooth integration of a lower kids’ washbasin

▲起伏墙面取代传统挡板 an undulated wall replaces traditional baffles


In the washroom, organic forms are as sculptural as they are functional. The washbasins are conceived as stone pillars stacked by interlocking layers and interspersed with brass components. The intricate central piece has integrated mirrors, decorative light fixtures, waste bins, paper towel holders, hangers as well as small planters. Replacing traditional baffles in male washroom, an undulated wall carves out just enough visual separation between the urinals. The gentle experience is finessed with thoughtful phone-holders spanning from a transitional brass strip.

▲电梯厅墙面采用与公区一致的槽纹肌理 the wall of elevator lobby adopts the reeded stone texture

▲轿厢内部采用弧角设计并加入自然纹理 the interior of the elevator car continues the streamline and natural design

▲楼层显示屏与蚀刻金属板门头无缝结合 seamless integration of the floor display panel under etched metal plate


“Though we tend to believe, in architecture as in literature, that an important work should be complicated, many appealing buildings are surprisingly simple, even repetitive in their designs.”- Alain de Botton, The Architecture of Happiness

For a period of 3 years, Lukstudio has honed a skillset working with many parties to refine humble spaces in an ever-changing commercial environment. We believe that simple user-centric spaces bring small pleasure in the everyday. We hope our endless efforts would last in the physical world and serve the public realm.
