位于美国德梅因的公共图书馆，由大卫·奇普菲尔德设计。建筑师为该图书馆创造了一个与周围公园融为一体的空间，既与城市街区相呼应，又延伸到公园中，营造出不同特点的外部空间。入口处的 Gateway Gallery 是一个灵活的多功能活动空间，既增强了建筑物在公园和城市之间的桥梁作用，又模糊了图书馆和公园之间的界限。建筑的屋顶覆盖着绿色的地毯，从相邻的街区看来，建筑物与公园的连续感十分明显。屋顶不仅减少了新建筑物的视觉影响，还具有重要的环境作用，避免了通过这种尺寸的屋顶引导水流所带来的问题。此外，通过增加建筑物的质量，可以防止温度的骤变，从而降低气候控制的成本。此外，图书馆还容纳了教育设施、儿童游乐区和一个带咖啡厅的会议厅，强化了建筑物的公共性，并为城市提供了一个公共生活的平台。这个两层的混凝土结构坐落在一个地下停车场上，完全包裹在复合节能玻璃金属外皮中。在两个玻璃表面之间层压的铜网层可以减少耀眼的光线和阳光的照射，从而大大降低长期的能源成本。此外，铜可以根据时间的推移而改变外观。在阳光下，板材轻轻地发光，而在夜晚，当图书馆被照亮时，它们就像一层略透明的面纱。从内部看，这种金属网几乎是看不到的，因此保证了与公园的接触始终保持，并利用了阅读室的自然光。这个建筑物的外形是独特而有机的，在玻璃面板的微妙变化中获得了统一的外观。

总体来说，这个建筑物融合了现代化和自然元素。建筑师为该图书馆创造了一个与周围公园融为一体的空间，既与城市街区相呼应，又延伸到公园中，营造出不同特点的外部空间。这个建筑物采用节能玻璃外皮，内部采用铜网层，既减少了热量的吸收，又保留了建筑物与公园的联系。此外，图书馆还容纳了教育设施、儿童游乐区和一个带咖啡厅的会议厅，强化了建筑物的公共性。建筑的内部设计使人们可以看到公园的景色，营造出开放和透明的感觉。这个建筑物是一个独特而有机的结构，突出了建筑师的设计思想和技能。
The library forms an integral part of the new Des Moines Western Gateway Park. This area of the city is currently undergoing extensive redevelopment and the new library and park will become a centrepiece for the urban renewal of Des Moines. Located at the east end of the park, the new library acts as a link between downtown Des Moines and the park. On the one hand, it responds to the city block, but at the same time it stretches out into the parkland, floating in the surrounding landscape, thus creating outside spaces of different character while conveying to the visitor the feeling of sitting in the park while reading a book. The Gateway Gallery, a flexible and multipurpose activity space, forms part of a public route through the building, reinforcing its bridging character between the park and the city and blending the threshold between library and park. The roof is covered with a green carpet that gives the project a certain sense of continuity with the park when it is seen from the adjacent blocks. The roof not only reduces the visual impact of the new structure, but also has an important environmental role, avoiding the problems that channelling water through a roof of these dimensions would convey. Furthermore, by increasing the building’s mass it is possible to prevent the sudden changes in temperature that increase the price of climate control. The stacks are arranged in such a way that one will always be able to see into the park from the interior, creating a sense of openness and transparency. In addition to book stacks, the library also accommodates education facilities, children’s play areas and a conference wing with a cafe, reinforcing the public nature of the building and providing the city with a platform for public life.
The two storey concrete structure sits above an underground car park and is entirely wrapped in a composite energy efficient glass-metal skin. Laminated between two glass surfaces, a layer of expanded copper mesh reduces glare and solar gain by 85%, thus greatly reducing long-term energy costs. Moreover, the copper gives the skin a changing appearance depending on the time of the day. The panels glow gently in the sunlight, whereas at night, when the library is illuminated, they appear like a slightly transparent veil. From the interior, this metal mesh is almost invisible, thus ensuring that the contact with the park is maintained at all times and taking advantage of the natural light in the reading rooms.

The library will be an integral part of the new Des Moines 'Western Gateway Park'. This area of the city has been scheduled for intensive brownfield regeneration, and the new library and park will become a centerpiece for the urban renewal of Des Moines. Located at the east end of the park, the new library acts as a link between downtown Des Moines and the park. On the one hand, it responds to the city block, but at the same time, it also stretches out into the parkland, floating in the surrounding landscape, thus creating outside spaces of different character while conveying to the visitor the feeling of sitting in the park while reading a book.
The Gateway Gallery, a flexible activity space, forms part of a public route through the building, reinforcing its bridging character between the park and the city and blending the threshold between library and park.
The two-story concrete structure sits above an underground car park and is entirely wrapped in an innovative, energy-efficient glass skin. Laminated between two glass surfaces, a layer of expanded copper mesh reduces the glare level and solar gain, greatly reducing long-term energy costs. The mesh is the only sun-shading device necessary, ensuring that the view from the inside into the park is maintained at all times. Slight variations in the makeup of the panels provide the library with a differentiated yet uniform skin, emphasizing the organic shape of the building.
In addition to book stacks, the library also accommodates education facilities, children's play areas, and a conference wing with a café, reinforcing the public nature of the building and providing a platform for public life. Administration and back-of-house services are to be found in the east wing. The stacks are arranged in such a way that one will always be able to see into the park, thus creating a sense of openness and transparency.
