架构师提供的文本描述。木三层房屋由于工地合同和建筑标准法律的原因，都有防火外墙。防火外墙的整个室内表面必须用增强石膏板覆盖。正因为如此，二楼和三楼的楼层都是通过石膏板用螺栓连接到外墙上的。

Text description provided by the architects. The wooden three-story house has fireproof external walls by the reason of both the site contract and the building standard law. The whole indoor surface of fireproof external walls must be coverd with reinforced gypsum boards. Because of that, floors of both the second and third floor are connected to external walls by just bolts through the gypsum boards.

换句话说，地板是从木制框架的角度与外墙分离的。

In other words, the floors are detached from external walls from the point of view of wooden framework.

地板由一般120毫米x 120毫米分段木材并排排列而成。

The floors are made of general 120mm x 120mm sectioned lumbers arranged side by side.
