MH办公楼

项目坐落于东京都西南部的三鹰市(Mitaka)，是一栋隶属于当地物流公司的“控股”办公楼。项目场地面朝东京都南北方向上的主要高速公路，考虑到三鹰市的长期发展，场地被划分为多个部分，根据一期规划，该地块不日将成为公寓用地。

It is an office building for “Holdings”, which is controlled by a logistics company based in the city of Mitaka, west of Tokyo. The site facing the metropolitan highway runs north to south, and after being divided in consideration of its actual use in the future, it will be phased out and the apartments will be expanded in stages according to the first phase plan.

控股是指通过持有某一或多个公司一定数量的股份，从而掌握其管理及营运权的复杂体系。因此，作为公司的颜面，Gendai Sekkei co., ltd.事务所为MH办公楼采用了多元化而不是单一的建筑形式。本项目致力于通过建筑彰显出物流和运输行业公司的严谨与专业的工作态度。

Holdings is a system that spans a variety of companies, so the architecture, which is the face of the company, is expected to be not uniform but multifaceted. At the time of planning, we thought a building that embodied the certainty of work and the rigorous rules of a company originating in the logistics and transportation industries would be appropriate.

基于商业建筑的性质，MH办公楼的设计既区别于周边的建筑，同时又不过分突兀。为了兼顾建筑的私密性与开放性，同时考虑到隔音与抗震的需求，办公楼的四个外立面均采用了不同的处理方式。这种设计理念，避免了建筑过于封闭的情况，使项目以亲切友好的方式与周边环境完美相融。

Due to the nature of the building, it is not advisable to bury it in the environment, but it is not desirable for its existence to be too prominent. Therefore, in order to satisfy such conditions as privacy and openness, consideration for noise and vibrations, avoid the inaccessible environment of the outside and make the building intimate, each of the four turns of the building has different characters.

最为引人注目的北侧立面上，开窗的部分与封闭的墙体以同样的比率重复出现，形成富有规律的虚实对比。东侧立面采取了与北立面相同的设计手法，但是根据情况，开窗的面积与实体墙面的跨度略有不同。这两个立面上的外墙均采用了向室内弯折的形式，形成锯齿状的平面布局。而南侧与北侧的立面，则根据相邻住宅或公寓的情况，设置了固定窗与推拉窗。

On the north side, which is highly visible from the outside, the openings and walls are repeated regularly, and on the east side, the openings and walls are repeated with different spans in anticipation of a long elevation plan at the time of expansion. In both cases, the folded plate-shaped outer wall is brought into the interior as is. On the south and west sides, planters and sliding windows will appear depending on the adjacent houses and apartments.

办公楼共有三个楼层，屋顶设有太阳能发电设备，为了满足当地建筑高度限制的要求，建筑师将楼层的高度控制在最小值，并将深色的管线设备隐藏在天花板上。虽然楼层高度仅有2.3米，但是，全高的玻璃窗与折板状的墙壁，在保证室内私密性的同时，为人们提供了开敞流畅的视野空间，因此，人们在室内并不会拥有狭促或憋闷的感觉。

Based on the requirement to install solar power generation equipment on 3 floors plus ceiling with absolute height restrictions, we kept the floor height as low as possible and pushed equipment and wiring pipes, which tend to be dark, to the ceiling. The ceiling height of each floor was set to be slightly low at 2,300mm. However, the full-height windows, which are alternately arranged with the folded-plate-shaped walls, allow the line of sight to pass in a vertical direction, and the interior has moderate privacy and a large expanse without feeling low or cramped.

Gendai Sekkei co., ltd.事务所力图运用简洁而有力的建筑语言，打造一个经得起时间考验的办公楼。当摆放完家具后，MH办公楼又将呈现出一个全新的景象。项目旨在通过建筑提升该公司在当地的归属感，成为员工共同的家。

With a simple but powerful stance, the appearance of the architecture changed a lot with the installation of furniture, our goal being to build a building that could stand the test of time as the home of a company that is deeply rooted in the region.
