地点：英国，伦敦（9 Cargreen Rd, London, United Kingdom）
来自建筑师的介绍。Paxton 集合住宅位于伦敦南部 Croydon 区的一个复杂场地内，该场地属于当地开放商。这里曾经是一栋空置的混凝土框架的旧办公大楼，它被寮屋居民占据使用。而现在，该建筑已经被精心改造成为一栋极具创新性的住宅，拥有四十三间公寓和一系列公共空间。
有角度的阳台，以及将入户交通从建筑中半抽离出来的设计，消灭了完全北向的户型，让 Paxton 集合住宅中的每一间公寓都能享受到充足的阳光。
此外， Paxton 集合住宅在入口大厅一侧设有一片工作区，在顶层设有一间备用卧室。这些空间为所有住户共享。工作区除了与西侧的主入口相连外，还单独有一个南侧的入口，方便住户从 Cargreen 路直接进入。备用卧室可以满足住户生活的额外需求。建筑师还贴心地在顶层的公共屋顶露台设置了设备齐全的烧烤区。完善的公共服务设施让整栋住宅的社区氛围浓厚。
alma-nac 总监 Caspar Rodgers 说：“如果保持原有建筑的出入口设置和交通组织不变的话，设计会采用传统的中间走廊两侧公寓的布局形式。但是这样不可避免地会出现单朝向的北向户型。我们尝试了各种方案，希望让每一间公寓都能有双朝向。最终，我们选择了在北向将走道从建筑主体中剥离出来的方式实现了这一目标。走道距公寓的北向房间有一定的距离，并且进行了减震设计，最大限度地减少对于住户的影响。这样的交通系统设计也让流线更加明确。主要的公共服务设施集中在交通核心筒的周围，将分属各户的私人区域和住户共享的公共区域分离开来。”
开发商Joseph Homes 的发展总监 Mike Stott 说：” Joseph Homes 的产品研发团队和 alma-nac 设计团队密切协作，打造出了这一栋美观、实用且可持续的具有创新性的集合住宅项目。该住宅项目可以为买家和住户创造出更优质的使用价值。“

Text description provided by the architects. Paxton House is an innovative housing solution on a complex site, for Joseph Homes in Croydon, South London. Forty-three dwellings and a series of shared spaces have been carefully crafted to occupy an existing concrete-framed building, a former office block which had been left vacant and was being used by squatters.
Avoiding a traditional central corridor arrangement, the architects have achieved a very different type of apartment block. Through the design of an external circulation strategy, every single apartment has been created as dual aspect, with a south facing living space.
Along the building\'s tight perimeter, each room on the south facing elevation is a living space which makes use of an angled balcony that provides privacy and directs views over nearby train tracks. Here, acetylated timber ensures the sustainable longevity of the cladding. This tightly set, animated facade naturally led to an angled balustrade design, ensuring privacy from neighbouring apartments and adjoining gardens alike, while maximising vistas from inside.
Angled balconies and external circulation mean Paxton House can boast sun-filled apartments that avoid looking north.
Paired apartments share entrance lobbies, recessed into the centre of the floorplan, enabling the use of efficient, slim layouts. Such an approach allows flats to have a more neighbourly feel, representing a departure from the typically anonymous multi-unit residential living.
Furthermore, Paxton House offers a spare bedroom and workspace. These are shared by the whole building and the latter can be found as part of the building\'s generously sized lobby, accessed from Cargreen Road. The spare bedroom, which re-addresses the requirements of apartment living in London, can be found on the top floor where a shared roof terrace with a built-in bbq also resides, all of which complete the strong communal aspect of Paxton House.
To minimise the impact of external circulation, the walkway\'s design is specific in terms of its physical position, lighting and acoustic performance. These walkways adopt chipped rubber, commonly found in children\'s playgrounds, to ensure acoustic dampening and create a characterful, experiential mode of passage.
These routes through the building are defined by specific material palettes with floors being colour matched according to level. On the ground floor is brick paving which extends into a courtyard outside, softening the threshold between internal and external spaces.
The ground floor also houses eight one-bed apartments, a studio apartment and a shared living room-cum-workspace. The first, second and third floors offer nine one-bed dwellings along with a studio and the fourth floor comprises three two-bedroom apartments, a spare bedroom and shared roof terrace.
Caspar Rodgers, Director of alma-nac: "Given the existing footprint and building aspect, a typical approach of general arrangement - a central corridor servicing flats on either side, would have resulted in North facing, single aspect apartments. We approached the scheme differently. Setting out to provide every single apartment with both dual aspects, but critically, with south/southwest facing living rooms, we achieved this through the provision of an external circulation strategy. ?We designed an external circulation structure running across the north facing elevation, acoustically dampened and physically offset from the building to minimise its impact to occupants. This doubled as a services tracking route, increasing the available head-height within the apartments, and reducing issues of internal service transfer."
Mike Stott, Development Director at Joseph Homes: "The Joseph Homes design team, working closely with alma-nac, created an innovative design that is beautiful, useful and durable; thereby producing an offering in the area that created real value for local buyers."
