我们力所能及的：在表现主义盛行的当下贴近极简

it is the least we could do: minimalism in an environment of expressionism




混合类型
hybrid typology



在中国，裙楼的建筑容积率往往无法应对城市人口密度增幅造成的压力，于是就导致了城市建筑过度依赖塔楼来达到市政规定的容积率标准。因此针对当下的城市环境，混合型建筑可谓是一个行之有效的解决方案。

In China, the perimeter block typology doesn’t usually return the Floor Area Ratio (FAR) necessary to satisfy inner urban densities. This leads to an over reliance on detached towers to meet FAR requirements. The perimeter block with a tower extrusion however, presents a useful hybrid.



一座塔楼从裙楼中拔地而起，这样的组合类型优势多多：裙楼能够激活城市街道边缘，并且实现良好的采光和通风，用户甚至还能享有一座“公私用随意”的内庭院；塔楼则可以在不逾越容积率标准的前提下，最大化利用建筑占地面积。

The advantages of the perimeter block (positive reinforcement of active urban street edges; well ventilated and naturally lit building interiors; and an internal courtyard that has the options of being private, semi-private-semi-public, or public space) are combined with the capacity of the tower to maximize floor area.


友好邻里
being a good neighbor



该项目被要求样式造型不能妨碍邻近建筑的日照。裙楼对此不会造成太大影响，但塔楼就难说了。我们最终通过夏季太阳直射点的位置、日照计算，敲定塔楼立面为东西朝向。

Urban form for this project was driven by the need to maintain strict solar access requirements to the neighbouring buildings. The low perimeter block did not impact solar access, however, the tower extrusion proved much more difficult to locate. Its final position exposes long east and west facades to low altitude summer sun.






金属百叶
metal petals



建筑的所有立面都应用了垂直屏障来隔热。高雅的薄板延伸出窗口并形成水平面，上布垂直穿孔金属遮光板，这些遮光板既可以合拢起来阻隔日晒，也可敞开方便观景。总的来说，这些遮光板如金属花瓣般覆盖在立面上显得统一而规整。

Surprisingly, all facades required vertical screens to prevent unwanted heat gain. Elegantly thin slab edges are projected past the window line and form horizontal ledges on which to sit vertical perforated metal sunscreens. These screens are closed enough to block the sun, yet open enough to not impede views out. En masse, these sunscreens present as a series of metal petals covering unified facades.





延伸的甲板为每层楼打造了额外的外部空间，同时将遮光板分隔开来，从而减轻大量金属遮光板带来的视觉压迫感。

Decks are then cut into the petals to provide outdoor space for each floor level, and subtle visual relief to the wall of petals.




极简为主，表现为辅
minimalism 1. – expressionism 0.



该政府办公大楼功能多样，它可以是档案馆、检测中心、员工食堂、商业街前咖啡馆，以及各种封闭或开放的办公空间。这样的设计不仅表现了建筑能够连接各类功能区间，也呼应了该混合型建筑由裙楼与塔楼连接而成。

The program for this local government building is diverse: document archives, testing laboratories, staff canteen, a commercial street-front cafe, and variety of closed and open office spaces. This suggests an architectural articulation of these programs. In addition, the typological hybrid suggests articulation of the perimeter building and the tower.





然而，相比探索功能连接等表面性问题的解决方案，我们更需思考：不同功能之间如何划分区隔？ 裙房和塔楼的结合相较于二者独立能产生多少差异？我们又如何花最小的力气来适应差异？为此，我们有两个主要的设计措施：一、统一规划幕墙，使其满足每一个不同区域的日照需求和遮阳性能标准； 二、所有入口都通入中央庭院。

However, rather than exploring these obvious solutions, the questions posed were: What are the differences in the program? What are the differences generated by combining perimeter block and tower typologies? And finally, what is the least we need to do to engage with these differences?
The answer to this question brought about two design responses: firstly, a unified façade which fulfilled the performance criteria for solar access and protection for each of the different programs; and secondly, the location of the entries for all programs into the central courtyard space.



半公共庭院
semi-public courtyard

集中动线的策略不仅创造了一个半公共的户外空间，还方便了不同部门间的合作交流。午餐时分， 围合的庭院还能提供活跃的就餐环境。

This centralized circulation strategy creates a semi-public outdoor space and provides opportunities for encounter and exchange amongst the different public departments. It also provides an active space for lunch in a protected courtyard landscape.



庭院还将通往南大门的公共人行道连通至步行桥的拟建位点再至庭院东北侧，这样的对角线路径也强调了庭院的“半公共性”。

The courtyard directly links the public footpath of the main southern entrance to a proposed future pedestrian bridge to the north east of the site. This diagonal shortcut further reinforces the semi-public nature of the courtyard.


异置的屋顶景观
roofscape as displaced landscape

为了引导员工走出大楼享受一番户外景色，我们将一层室内的地砖一路铺至庭院，并延伸到河边。这样的设计也为未来一楼开发更多公共/商业用途奠定稳健的基础。

To encourage the staff to get out of the building and enjoy the river frontage or the courtyard, the paving from the ground floor interiors flows directly into the courtyard and out to the river’s edge – a robust strategy for the future, when the ground floor develops more pubic and/or commercial programs.



在塔楼可俯瞰裙楼屋顶。该顶层有一座花园小亭，仿佛一座被“错置”的景观；员工食堂的门就开向此处，员工午餐，甚至是非正式会议，都可以在小亭子里进行。另外，还有一间机电房也被装扮成一座小亭。因而，整个顶层为租户提供了户外私人空间。

The tower overlooks the roof of the perimeter block and this space provides an opportunity for a major private outdoor space for the building tenants. A garden pavilion for staff lunches or informal meetings sits within a roofscape that presents as a displaced landscape. The staff canteen opens on to this roofscape. Plant rooms have been disguised as additional garden pavilions.





比我们想象的更令人瞩目
more visible than we think

在商业和零售环境中，每一栋建筑都追求标新立异，在以广告及标牌为主的街景中，建筑已成为企业理念和营销活动的 “延续战场”–然而，或许一座简约优雅且沉静的公共建筑比我们想象的更令人瞩目。

In a commercial and retail environment where every building is trying hard to be seen as different from its neighbours, where advertising and signage are dominating streetscapes, where buildings are becoming extensions of corporate logos and marketing campaigns – a minimal, elegant and calm public building may be more visible than we think.
