Ontario山坡上玻璃与石材交融的图书馆
RDHA embeds stone and glass library into grassy Ontario hillside

加拿大RDHA公司新建造的公共图书馆，特色是巨大的悬挑结构，倾斜的绿色屋顶和建筑的外置楼梯。Waterdown 图书馆和市民中心都位于距多伦多市一小时车程的汉密尔顿市。

This new public library by Canadian firm RDHA features a large slab that cantilevers over the landscape, and a sloping green roof and exterior stair that runs up the front of the building.
The Waterdown Library and Civic Centre is located in the city of Hamilton, about an hour's drive from downtown Toronto.

覆盖面积达23,500平方英尺（2,183 平方米）的建筑坐落于安大略湖旁长满草的山坡上。虽然从外观看，建筑相当贴合地面，但六层中有几层是陷在山坡下的。

这座多功能用途的建筑包括图书馆，社区服务办公室，社会遗产档案室和给老年人设计的娱乐中心。1919年成立于多伦多的RDHA建筑公司拿到了680万加拿大币的项目预算。

Encompassing 23,500 square feet (2,183 square metres), the building is nestled into a grassy escarpment near Lake Ontario. While it appears low-slung from the exterior, the building contains six levels – several of which are carved into the hillside.
The multi-use facility houses a library, a community service office, a heritage society archive, and a recreation centre for senior citizens. RDHA – a Toronto firm established in 1919 – was given a budget of $6.8 million Canadian (￡4 million) for the project.

该小组说，“RDHA 使用定制现成的组件，用普通的材料创造不寻常的建筑”。“即使像灯带这样最标准的元件也要在一定程度上增加优雅的感觉”。

建筑表皮由玻璃和石灰岩板组成。立面从几乎不透明到完全釉面。玻璃上的陶瓷熔块有助于减少吸收的热量。

"RDHA applied the studio's practice of customising off-the-shelf components to create an extraordinary building from ordinary materials," the team said. "Even the most standard elements such as strip lights were treated with a degree of care that adds elegance."
The building is clad in expanses of glass and limestone panels and fins. The facades vary from nearly opaque to fully glazed. Ceramic frit on the glass helps mitigate solar heat gain.

上部的悬挑结构“像”漂浮的白云质灰岩。

外部的楼梯缓缓抬高，连接到以玻璃幕墙为边界的室外露台。沿着楼梯是一个倾斜的有花卉绿植的屋顶。

The building's upper slab cantilevers over the sloped site "like a hovering block of dolomitic limestone".
An exterior stair gently ascends the site and arrives at an outdoor terrace bordered by glass walls. Running alongside the stair is a sloping green roof with flowering sedums.

内部弯折倾斜的走道连接着各楼层，解决了高度差带来的影响。

锯齿天窗和落地窗为建筑引入充足的光线。

Inside, a series of winding, sloped walkways connect various levels and resolve the site's height differences.
Sawtooth skylights and bands of floor-to-ceiling glazing bring ample daylight into the facility.

建筑中央的开放空间放置了图书，RHDA 分隔了四个“梯田”区域— — 一个用于儿童部分，其他三处用作青少年和成年人收集和阅读的场所。

“内部的地形增强了人们对周边景观的关注度，”该公司表示。“最高点是图书馆，四个由道格拉斯冷杉铺设的‘梯田’都缓缓升向最高点”。

Within the building's central open space, which houses the library, RHDA created four "terraces" – one for the children's section, and the other three for the teen department, adult collection and a reading atrium.
"The internal topography heightens awareness of the surrounding landscape," the firm said. "It reaches its peak in the library, where a series of four terraces step up towards the highest point in the building, demarcated by a path of Douglas fir book stacks."

室内装饰包括木材、 混凝土、 玻璃，覆盆子色和橙色的椅子也为建筑增添了颜色。入口走廊的道格拉斯冷杉木材来源于拆卸的图书馆。

可持续性是设计团队关注的问题。建筑使用无毒材料，在停车场使用生态调节沟-用地表径流水去除泥沙和污染物， 还设置了地下雨水收集系统。

Interior finishes include wood, concrete and glass, with raspberry and orange chairs adding pops of colour. In the entry corridor, Douglas fir accents are made from salvaged wood from a demolished library.
Sustainability was a concern for the design team. The building features non-toxic materials, bioswales – which remove silt and pollution from surface runoff water – in the parking lots, and an underground rainwater collection system.

新建筑相比所取代的旧图书馆，游客数量已经增加了 150%。“图书馆的访客喜欢他们有这样一个美丽能称为家的地方社区工作区，”该公司表示。

在加拿大其他图书馆项目包括由 Bing Thom Architects建筑事务所设计的在温哥华附近成角度的混凝土墙和弧线窗的项目，以及Schmidt Hammer Lassen的四个不同维度堆叠模块的Halifax图书馆项目。

The new facility has seen a 150 per cent increase in visitor numbers compared to the older library it replaced. "Library customers love that they have such a beautiful place community workspace to call home," the firm said.
Other libraries in Canada include a facility near Vancouver by Bing Thom Architects that features angled concrete walls and curved windows, and a Halifax library by Schmidt Hammer Lassen that is composed of four stacked blocks of varying dimensions.
