架构师提供的文本描述。这一令人兴奋的翻新和扩建，在悉尼的波茨点的一个世纪之交的露台房子，重点是一个宏伟和优雅的螺旋式楼梯，形成了关键的交汇处新旧部分的房子。楼梯横跨大楼的宽度，其特点是精致的扇形钢踏板从中央钢柱悬挑，蜿蜒通过六层分叉的水平，抵消了房子新旧两面之间的隔阂。楼梯被认为是一种元素，将当代和新的最小结构移植到精致、修整和正式的旧住宅部分。

Text description provided by the architects. This exciting renovation and extension of a turn-of-the-century terrace house in Sydney’s Potts Point focuses on a grand and gracefully spiralling stair that forms the pivotal junction of the old and new parts of the house. The staircase, spanning the width of the building, features delicate fan-like steel treads cantilevered from the central steel post and winding their way past six split levels, offset between the old and new sides of the house. The stair was conceived as the element that grafts the contemporary and new minimal structure to the refined, trimmed and formal older portion of the dwelling.

宽敞的起居区和私人区域从楼梯的两侧开放，每层有一个区域在新旧建筑之间交替。正式生活、就餐、厨房和非正式生活；主套间、客人套房、书房和洗衣房：每个区域通过水平上的偏移保持一种自然的隐私感，但在楼梯所创造的开放和运动中保持着一种相互联系的感觉。

Spacious living areas and private zones open out from each side of the stair with one area per level alternating between the old and new building. Formal living, dining, kitchen and informal living; master suite, guest suite, study and laundry: each zone maintains a natural sense of privacy from the other through the offset in level yet maintains a sense of interconnection in the openness and movement created by the stair.

在内部，在旧部分的房子完成是现代和优雅的剥离-古典风格，深冲脚板，仪表板门和宽木地板，所有的光泽白色油漆和抵消了丰富的颜色设置灰泥墙。相比之下，主要的白色延伸与光泽白色地板，特点是黑色染色木材-木板细木工元素跨越三个层次。青铜窗框，铁器和装饰结合了三层住宅的两个部分。

Internally, finishes in the old portion of the house are contemporary and elegant in a stripped-classical style with deep flush skirting boards, mannered panelled doors and wide timber floorboards, all in gloss white paint and offset by richly coloured set plaster walls. In contrast, the mainly white extension with the same gloss white floorboards, features a black stained timber-boarded joinery element across three levels. Bronze window frames, ironmongery and trims unite both portions of the three-storey home.

从外部看，通过一个13米宽的滑动门墙，可以俯瞰一个口袋花园，突出了与户外的联系。此外，双折叠门是隐蔽的细木工，以提供一个无缝连接的分层后花园与成熟的胡椒树。这所房子提供了非凡的空间，补充了自信的形式，低调的设计和精致的细节。

Externally, the connection to the outdoors is accentuated through a 13 metre clear span wall of sliding doors that overlooks a pocket garden. An addition to this, the bi-folding doors are concealed by joinery to provide a seamless connection to the tiered rear garden with mature pepper tree. This house offers extraordinary spaces complemented by confident forms, understated design and exquisite detail.
