D(emountable)办公大楼位于荷兰代尔夫特，是一座现代、可持续且可以完全拆除的独特建筑，与市中心历史悠久的建筑群形成了鲜明对比。项目场地由该建筑的设计方cepezed事务所所有。

Building D(emountable) is a modern, sustainable and fully demountable structure on the site of a historic, monumental building complex in the center of Dutch city Delft. This site is owned by cepezed, an agency with expertise in the development, the design and the realization of buildings.

轻量、灵活、零气体 Lightweight, flexible and gas-free

D(emountable)大楼是在拆除状况不佳的既有建筑物之后，基于完全相同的场地面积建造。大楼的尺度为11.5×21.5米，共包含四个楼层，每层提供200平方米的可租用面积。除了可拆卸和可重新安装外，该建筑还具有超轻量的特征：材料的使用量被减少到最低。建筑内部的布局也极为灵活，不仅没有设置任何气体管道，还配备以热回收的功能。除了首层空间由混凝土浇筑而成，建筑的所有组件均由干式安装的模块构成。

Building D(emountable) has exactly the same footprint as the existing building that was no longer good and was demolished. It measures 11 by 21.5 meters and has four floors of about 200 square meters of lettable floor area each. In addition to being demountable and remountable, the structure is also super lightweight: the use of materials is kept to an absolute minimum. The building is also completely flexible in its arrangement, has no gas connection and is equipped with heat recovery. The ground floor is made of poured concrete, but otherwise, all building components are modular and dry mounted. Supreme simplicity has been an important principle in the design.

D(emountable)大楼由精心优化过的建筑套件构成，拥有一个钢制的、极度轻薄的预制主体支撑结构。承重楼板和屋顶由预制的轻质单板层积材（LVL）构成。LVL组件的轮廓从外部清晰可见，成为建筑美学的一部分。地板由部分回收的PVC材料制成。
