剖面图

“Lumber 4”是一座商业和办公建筑，共六层。地下一层为商业楼层，地上五层为办公空间。建筑结构由大量木材构成，支柱和横梁由胶合层压木材制成。

"Lumber 4" is a commercial and office building spanning six floors. A recessed ground floor constitutes the commercial level, with the five floors above dedicated to office spaces. The structure is composed of a mass timber construction with columns and beams made of glued laminated timber.

楼板采用 CLT 和混凝土的复合结构，形成了一个纤细、高效的楼板系统，不仅跨度大，还能满足防火和隔音要求。底层的对角线为车辆进出大楼提供了便利。相邻建筑阶段的现有通信核心有助于横向稳定性和办公楼层的进出。在三层和四层之间，引入了一个中庭，中庭内部的楼梯由大量木材制成。木质元素在建筑内部得到了充分体现，在冬季提供了温暖，在夏季提供了凉爽。

The floors are constructed using a composite structure of CLT and concrete, creating a slim and efficient floor system that spans long distances while also addressing fire and acoustic requirements. Diagonals on the ground floor facilitate better vehicular access around the building. The existing communication core from adjacent building phases contributes to lateral stability and access to the office floors. Between the third and fourth floors, an atrium with an internal staircase made of mass timber has been introduced. Wood elements are prominently displayed in the interior, providing warmth in winter and cooling in summer.

外墙由预制的松木弧形木构件组成，并涂有绿色油漆。弧形构件上方的屋檐是直的，在面板上形成一个弧形阴影。随着时间的推移，阴影下的油漆会逐渐风化，从而使外墙的弧形部分由浅到深不断变化。

整个建筑使用的隔热材料是木纤维。覆层由经过防火处理的松木组成。所有的承重结构都是外露的，外墙则由白色颜料的云杉板覆盖。隐蔽的服务区和会议室使用了木丝隔音板。可见导管涂成浅米色。宽大的落地窗视野开阔，自然光线充足。

The facade is composed of prefabricated curved wooden elements in pine, treated with green paint. The eaves above the curved elements are straight, creating a curved shadow on the panel. Over time, the paint under the shadow will weather, leading to a changing facade with lighter and darker curved sections. The insulation used throughout is wood fiber. The cladding consists of fire-treated pine. All load-bearing structures are exposed, and exterior walls are clad with white-pigmented spruce panels. Wood wool acoustic panels are used in concealed service areas and meeting rooms. Visible conduits are painted in a light beige color. The large floor-to-ceiling windows open up to the view and provide ample natural light.

该建筑的建造以创纪录的速度完成，从详细规划到施工仅用了 12 个月。"Lumber 4 "证明，与相同技术标准的混凝土和钢结构相比，建造具有竞争力的木材建筑是可行的。建筑竣工后，90% 的房屋已被租出。奥斯洛特担任该项目的建筑师、室内建筑师和木结构工程师。

The construction of the building was completed in record time, with detailed planning and construction taking only 12 months. "Lumber 4" has demonstrated that it's possible to construct competitive timber buildings when compared to the same technical standard concrete and steel structures. The building was 90% leased upon completion. Oslotre served as the project's architect, interior architect, and timber structural engineer.
