We renovated a Siheyuan-style building located exactly in front of the East Gate of the Forbidden Palace (at the heart of Beijing), using hollow blocks of polyethylene.4 types of blocks were produced by rotational molding to be joined and stuck up, as the structure of the extended part. The main structure for the city of Beijing is masonry bricks. Blocks made of polyethylene are in this sense a modern version of masonry. It proves high performance in insulation and passes through light to create a gentle space of Zen, just as the paper did used for Siheyuan in the past.

　　隈研吾，这位享有极高国际声誉的日本知名建筑师，因其作品散发日式和风与东方禅意，在业界被称为“负建筑”、“隈研吾流”;又以自然景观的融合为特色，运用木材、泥砖、竹子、石板、纸或玻璃等天然建材，结合水、光线与空气，创造外表看似柔弱，却更耐震、且让人感觉到传统建筑的温馨与美的“弱建筑”。

　　隈研吾建筑事务所在中国北京东华门附近采用聚乙烯空心砖将一个四合院打造成为温和禅意的私人会所，这里离恢弘的故宫咫尺之遥，目前只接待会所会员。

　　老北京，可是砖儿砌起来的，这个250平方米的四合院也不例外，整个设计中也使用到了砖，不过却是现代版的砖石---隈研吾采用了四种尺寸的浅色聚乙烯空心砖，其具有良好的热工性能，却又能像纸一样通过光线。整体设计看上去通透宁静，意蕴深远，充满禅意。而在屋顶的室外空间可以看到故宫东华门、护城河和远处的白塔，视野极佳。

　　为了完成这个茶室项目，设计团队使用了4种类型的空心聚乙烯快砖石，这是通过旋转式接合形成的，代表着中国城市的现代版砌筑砖。聚乙烯块砖石隔热性能靓好，并能让光线透入，营造光线柔和的空间。
