“地下变色龙”：帘幕汽车旅馆

曼谷曾因其作为一个罪恶之城的形象而臭名昭著，卖淫、赌博和其他非法活动都在此共存和滋生。地下杂交体，是同时隐藏和促进在正确和错误、合法性与非法性、道德与堕落之间摇摆的城市活动的构筑物。

帘幕汽车旅馆是最独特的地下杂交体。它的形态旨在满足城市人对自我的解放。这个旅馆建筑核心有个中庭，在中庭与外部则是通过一个狭窄的隧道连接，而这个开口让秘密的伴侣可以坐在他们的汽车中隐秘地进入建筑内部。建筑本身建在一个露天的停车场上，两旁都是以帘幕遮蔽的停车位，而这些停车位上方则有直达楼梯与“爱巢”相连。露天停车场也有单独的出口，使这些爱侣们可以在避免被窥伺的情况下离开此地。

除了为大众介绍曼谷诸多不为人知的历史背景之外，帘幕汽车旅馆同样展现了另一种巧妙应对热带城市生活的杂交体。建筑物的中庭空间通过堆叠效应维持通风，从隧道吸入空气，并让它们通过庭院上方的开口向上、向外吹出。连通街道和建筑物中庭的隧道也可以作为一种滤网，让低污染的空气进入庭院，调和庭院的热度和湿度，同时不受灰尘和街道噪音过多的影响。这种对转换噪音污染以及含有CO和尘埃的自然空气的处理，对于在热带城市的生存至关重要。□

Bangkok is notorious for its mark of a city of sins, where prostitution, debauchery, gambling,and other mischievous activities exist and thrive.Underground Hybrids are architectures that simultaneously conceal and promote urban activities that teeter between right and wrong, legality and unlawfulness, morality and depravity.

The curtain sex motel is one of the most unique Underground Hybrids. It is a typology created to satisfy one of the city's naughty secrets. It is a simple concrete courtyard building with a blank street-facing façade punctured by a lone tunnel.The opening allows secret romantic partners to enter the building discreetly in the privacy of their cars. They emerge onto an open-air auto court,lined with curtained parking spots, which in turn are connected to private "love" chambers. A secret courtyard exit also allows the lovers to escape onto a side alley unnoticed to their car.

Aside from providing historical background for one of Bangkok's many shady secrets, the curtain sex motel also demonstrates a wonderful hybrid response to tropical city living. The courtyard space at the centre of the building is continually ventilated through stack effect, drawing in air from the street tunnel, up and out through the court opening above. The tunnel that connects the street to the building's courtyard also acts as a sieve that allows semi-tainted air to enter the court, just enough to chase away the heat and humidity in the court, but not too much that dust and street noise overpower the space. It is this careful negotiation of noise pollution and natural air tainted with carbon monoxide and dust that is crucial in surviving in the tropical city.□
