太古汇位于广州市的商业中心，集购物商场、两座甲级写字楼塔楼、酒店及服务式公寓于一身。商场每天游客数以万计，集团希望藉这个可持续发展洗手间提升其公共设施，并增加公众环保意识，为商业及零售业树立可持续发展的榜样。设计力求回归自然，包括形式上以及环保上 – 可持续发展、空间塑造及人体舒适带动了整个设计。
A bright grotto – a contemporary abstraction of nature – to refresh shoppers amidst delicate garments and dazzling commodities, is our design concept for this underground toilet.
Situated in the commercial center of Guangzhou China, the TaiKoo Hui is a mixed use complex incorporating a shopping mall, two Grade-A office towers, a hotel, and serviced apartment. The shopping mall receives tens of thousands of visitors daily, and its amenity facilities require an upgrade. The sustainable design toilet aims to raise the environmental awareness in the public realm and to become the role model of sustainability in the commercial & retail sector. The design aims to tie back to nature, formally as well as environmentally. Sustainability, spatial sculpting and human comfort drive the whole design.

Minimum alterations are made to the original efficient layout, to minimize structural and piping alteration. It consists of three corridors of cubicles, washbasins & urinals. Wall furring was removed, the ‘found’ round and tilted square columns are painted to form a homogenous white mass to engage the space with unique shape and angle that hint the underlining structures.
White and ‘cyclorama’ setting is applied to give a bright and clean ambient – walls join the ceiling seamlessly and smoothly with curved surfaces, to diffuse light for plants to duo-function as general lighting. Glass Fiber Reinforced Gypsum (GRG) panels are used to form the curved surfaces, for their durability and use of recycled materials. The curved edges also eliminate possible dark, dirty edges.
▽ 设计将洗手间塑造成一明亮的石窟 – 一个对自然的当代抽象演译。白色洗手台与曲面天花连成一整体，树形的形象呼应其回收洗手用水并用作灌溉的环保理念。
The toilet is expressed as a bright grotto – a contemporary abstraction of nature. The new washbasin counter curves up to join the wall and ceiling as one integral piece, with a tree-shaped icon echoing to its collection of grey water for irrigation.
The original wall furring was removed to reveal the structure. The ‘found’ round and tilted square columns are painted to form a homogenous white mass to engage the space with unique shape and angle that hint the underlining structures.
Indoor plants are grown to purify air, raise indoor oxygen level, and add life and colors of nature. The plants are grown above human level for better management and tidiness. Pots are hidden inside the GRG furring, to enable the plants to form pure strokes of green. Irrigation utilizes grey water collected from the wash basins, supported by a local filtration system.
The floor is a newly-casted dark grey terrazzo stone. Here the original sandstone and grey tiles are crushed as aggregates for the new terrazzo, forming unique silver grey chips to reveal the idea of recycle.
The new washbasin counter is an all-in-one station. The white corian counter curves up to join the LED lighting strip, mirror and ceiling as one integral piece, with a tree-shaped icon echoing to its collection of grey water for irrigation. An integrated water tap cum hand dryer product is installed for sustainability and cleanness: it avoids dripping water on counter-top and floor, saves spaces and paper towels.
Waterless urinal, water-saving water-closet & vacuum toilet are applied to save water usage by 80%, and reduce waste volume by 60% on a daily basis. Two fans are added to enhance fresh air movement, to replace mechanical cooling in winter and to reduce the cooling load in summer.

Baby care room & Children toilets 母婴室及兒童洗手間
这个纯白「石窟」内，为图案不同的房子，并以高低不一的拱门连接 – 高门通往母婴室、矮门通往儿童洗手间。
The baby care rooms are also upgraded with improved facilities and a playful design. The original layout is given minimum alterations to allow for a seating area and an additional baby care room, the resulted kinked passage and simplified arches continue the ‘grotto’ idea.
Within this white grotto are rooms of patterns, each consists of a simple geometry or theme, and led through arched openings of varying heights – higher ones for the baby care room, and lower ones for the children toilets.
▽ 母婴室的折曲通道及简化拱廊延续「石窟空间」这设计概念。入口为一通高的几何图案，由此引进「石窟空间」，再以高低不一的拱门连接各房间 – 高门通往母婴室、矮门通往儿童洗手间。
Looking from the entrance, the kinked passage and the simplified version of arches continue the grotto idea. A full-height pattern of simple geometry marks the entrance. Arched openings of varying heights lead to the individual rooms – higher ones for the baby care room, and lower ones for the children toilets.
Magnified patterns gives a sense of playfulness for the baby care room, while light grey tiles and simple arches make the small passage look spacious and light.
Each room consists of a simple geometry or theme, as a self-contained world for the family and the kids. Mirrors for the children toilets are shaped according to the geometry of the individual rooms.
The original layout is given minimum alterations to allow for a seating area and an additional baby care room. The whole facility is a collection of rooms of patterns within a white grotto.
