1 Lyric Square是一座建于20世纪70年代的办公楼，共14层，由Richard Seifert设计完成，是国王大街（King Street）开发项目中的重要一环。该办公大楼位于伦敦的哈默史密斯区（Hammersmith），该区域正在飞速发展，地理位置优越，交通十分便利，只需要乘坐公共交通工具便可以达到泰晤士河畔，享受在河边漫步的悠闲时光。然而近年来，该办公楼的室内装修和改造工程却一直与其最初的设计概念背道而驰。狭长的平面、较低的层高、低效的交通核、失败的机械和给排水系统、以及保温隔热性能欠佳的建筑外墙都给这座年近半百的建筑带来了不小的挑战。但这同时也为建筑师提供了机会，他们可以通过改造来突出办公楼原有的特点，从而为一些目前欠佳的室内空间重新带去商机。

1 Lyric Square is a fourteen-storey 1970’s office building designed by Richard Seifert as part of the King Street development. Its location, in Hammersmith, an area undergoing rapid change also offers first class transport links, ideally situated to make use of public transport and proximity to the river walks by the Thames. The building has been subject to piecemeal fit-outs and alterations but was otherwise as originally conceived. The narrow plan, low floor to ceiling heights, inefficient cores, failing M+E systems and poorly insulated facades all posed challenges. However, the building also presented opportunities to celebrate the original architectural character and improve under-developed areas that could be re-purposed for commercial benefit.

设计任务 | What was the brief

本次改造任务由建筑事务所Stiff+Trevillion负责，他们需要在大楼中创造出一个A级的工作空间。建筑师以原建筑的特点和局限性为出发点，为人们重新设计一个舒适宜人的办公空间。

Stiff+Trevillion were commissioned to re-imagine 1 Lyric Square and provide new Grade A workspace. Embracing the unique character and constraints of the original structure the design aimed to reposition the building for a newly emerging tenant profile.

改造方案 | What were the solutions

首先，设计团队将原有的MEP系统改造为逐层控制，每层设有独立的机房，再将机房与新的窗户和立面系统相结合，而原先设在2层和14层的未得到充分利用的机房则被改造为高质量的办公空间。同时对现有的办公空间重新规划布局，尽可能地拆除不必要的天花板，最大限度地扩大了层高并改善了空间的视野和自然光环境。

Fundamentally changing the MEP strategy to floor by floor plant rooms in combination with new windows and facade systems, allowed the design team to convert previously under-utilised plant spaces at level 1 and 13 into high quality office accommodation. Reconfiguring the services within the existing office spaces removed the necessity for ceiling distribution, maximising the constrained floor to ceiling heights and improving views and natural light.

对交通核重新规划以提高其效率，再加上较为合理的MEP系统，办公楼室内空间的净面积增加了15%。这个数据主要得益于14层和2层两个楼层的改造：其中原先位于14层的旧机房被改造为了办公和休息空间；2层原为垂直方向的过渡空间，主要用于连接首层入口和3层的办公空间，经过改造这部分空间也被重新加以利用。此外，建筑师还将原先的辅助服务空间改造为了一个壮观的屋顶平台，在二层打造出一个全新的办公空间。户外的露台空间仿佛城市中的绿洲，默默地迎接着到访的人们。这里远离城市的喧嚣，人们可以在此进行一系列非正式的会谈。建筑师将原先的封闭楼梯间打开，不仅将更多的自然光线引入室内，更改善了下层空间的交通流线，为人们创造出一个可以相互协作的、更加积极的办公环境。
