风拱顶房子

项目名称：风拱顶房子

所 在 地：新加坡

这是由Wallflower设计的新加坡风拱顶房子。整座房子的建筑形式需要将建筑的外壳最大化。当然还要考虑其他的因素，比如邻居房子的设计形式和内容，每日的太阳路径和盛行风。从概念上讲，这座房子是一个提高的钢筋混凝土结构。在实践中，所有的房间都有朝东或者朝西的墙，前庭是朝北或者朝南。管状结构，有效的消除和抵制固体钢筋混凝土在东西产生的热量，但却鼓励开放式南北轴的被动冷却。北立面和南立面是由木质屏幕组成的，且他们的安装方式多种多样。他们是卧室的隐私过滤器，也是第一层的眩光，太阳能热量将还原到这一空间后面。

家庭聚会是很日常化的活动，客户还会定期的有大型的庆祝晚会等活动。一层在设计上采用了视觉膨胀的效果，鼓励交织空间的同时，还十分注重整个房间的整洁特性。交织空间允许人们可以在花园，起居室和饭厅之间自由行动。在构造上，原有的树木代替了人造墙的效果，给人们惬意的感觉。房子临近的窗户，虽然比较狭窄，但是仍然能使太阳到达草坪。这块自由的区域可以作为聚会和玩乐的空间。游泳池被放置在花园和生活空间的中心位置，这不仅是建筑的中心位置，也是中央蒸发冷却表面的中心。

Wallflower Architecture + Design have designed the Wind Vault House in Singapore. As the brief was substantial， the overall form of the house needed to be pushed to the envelope limits. Naturally， there are also other considerations; the context and proximity of neighbouring homes， the daily sun path and the prevailing winds. Conceptually， the house is a raised reinforced concrete tube whose open ends are oriented in a general north-south direction. On this site， the prevailing breezes also blow in from the south， from the direction of the nearby coast line. In practice， all rooms have walls that side either east or west， and front north and south.

The tubular structure resists east west heat gain thanks to the solid mass of the reinforced concrete but encourages passive cooling through the open north south axis. The north and south facades are treated with timber screens and their contribution is multifold. They are privacy filters for the bedrooms and are the first layer of glare and solar heat reduction to the spaces behind. The timber fins of the screen can also be angled so as to catch a breeze or to increase privacy as and when needed.

Family gatherings are a daily occurrence， and large celebratory functions also feature regularly for the client. The first storey is designed to be visually expansive and uncluttered， and encourages the intermingling of space， whether one moves through the garden， living or dining. The perceived spatial boundary is not architecturally delineated in a traditional sense， but by a soldier-line of narrow polyalthia trees along the boundaries of the site. However， architecturally， the trees provide a level of purpose no man-made wall is able to.

It shields the house from neighbouring windows but its narrow footprint still allows sun to reach the grass， while freeing up space on the lawn for play and parties. What may not seem so obvious though is that the tines of polyalthias are literally evaporative fingers， combing the air of some of its heat each time the wind blows. The swimming pool is placed centrally between garden and living both as a focal centre and also as a central evaporative cooling surface.
