PULSA，与浅水湾的一次对话

浅水湾是香港最高档的住宅区，面朝大海，背靠青山，新月形的海湾有着旖旎的热带风光，群山青翠欲滴是中国传统的山林景色。Aedas受业主委托，要在风景如画的浅水湾半山坡建造8幢可以尽享美景的独栋豪宅。

在这里建造豪宅并不难，但要在不破坏自然美景的同时，让住户和行人最大程度享受自然美景，是个极具挑战的事情。项目设计师柳景康（Cary Lau）给出的答案是：融入它、成为它、享受它。

“当建筑融入自然，成为自然的一部分，破坏也就无从谈起了。”设计师柳景康从建筑的外形和分布两方面考量，让PULSA与自然融为一体。

地块周边满是枝繁叶茂的大树，郁郁葱葱，自然气息浓重。设计没有选择硬冷的四方形体量，而是就地取形，以浅水湾最常见的海浪为蓝本，借用它富有律动、变化万千的线条勾勒建筑轮廓，让建筑变得生动、富有自然气息。每一幢、每一层都是独一无二的线条，彼此区别，又相互联系。从周边走过，不同的角度会看到建筑不同的样子，像极了瞬息万变的海。建筑外立面的材料也精心挑选了玻璃幕墙，当阳光在起伏的曲线玻璃上衍射，便把周边的风景倒映在上面，一步一换，建筑的表面上总是自然风景。

地块不是规整的几何形状，两侧需按规定预留非开发缓冲区，可使用面积十分有限，8幢住宅势必要分成两排。地形狭长且复杂，低处有弧度，没有全部正对浅水湾，地处40°斜坡，高差大约22米，势必会造成实现遮挡。这一系列限制因素导致住宅的高度和朝向需要慎重抉择，否则海景视野将大打折扣。

横向比较了多种方案，最终设计师柳景康选择顺应山势，充分利用高处的视野优势，上5下3阶梯式排列住宅，并将上排地基抬高2米。既避免视线遮挡将上层高处视野价值发挥到最大，又不影响住宅空间的舒适感，同时保证下层住宅可以拥有更多正面角度朝向浅水湾，让每栋住宅都能拥有最大化的海景景观。并将坡度劣势转化为空间优势，充分利用住宅与山形成的夹角，将车库、后勤机电等功能隐藏其中，不但减小了住宅对山体地形的破坏，还降低了配套功能空间对住宅外观的破坏。

“融入自然只是开始，从时间的维度去计算影响，才是有意义的。” 设计师柳景康在建筑绿化节能上做了很多考量。预先规划出多处绿化场地，街墙内、建筑间，并在每幢住宅屋顶设置绿色景观平台。采用中空LOW-E镀膜玻璃作为外立面，使用对流窗，并设置了屋顶泳池、架空地台，全方位遮阳隔热提升节能效果。住宅获得了绿建环评（BEAM）金级评审。

设计师柳景康表示：“在设计之初，我和我的团队就在思考，如何才能减少破坏和突兀，它属于自然，也属于它自己。”

Pulsa - Sea Waves by the Bay

Repulse Bay is among the most luxury residential areas in Hong Kong. Backed by mountains, Pulsa is steeply sloped with spectacular sea view of the Bay. Eight houses are arranged in two tiers to optimize sea views, yet minimizing disturbance to the natural slope.

“When the architecture is integrated with nature and even becomes its integral part, damage to the environment is minimised.” According to Aedas Executive Director Cary Lau. Embracing residents and visitors with nature is what Cary’s design plans to achieve.

Surrounded by lush landscapes, the design motif of Pulsa is inspired by sea waves. Different floor area, layout, building profile and materials have been adopted, bestowing each house a unique identity in a coherent statement.Facades of houses create diffractions and reflections, creating ever-changing perspectives from different viewing angles, to surround residents by the natural beauty of Repulse Bay.

Located on a slope of approximately 40 degrees, the plot is originally in irregular geometric shapes. Not-for-development areas need to be reserved as required by regulations, to provide reasonable buffer between the adjoining developments.Nonetheless, Cary managed to optimize space and desirable views by arranging houses in two rows.

“Integrating nature into architecture is just the beginning. We should focus on its long term impact, to make our design meaningful.” Cary has put thorough considerations to reduce carbon footprint for Pulsa. The project achieved BEAM plus GOLD in Provisional assessment for its environmentally-friendly design and selection of materials. Different Low-E coatings not only control glare, but also reduce heat transfer across building envelops. The design applies cross-ventilation to enhance thermal comfort, while outdoor swimming pools are set on roof floor and the floor system raised on roof, to enable an effective energy- saving architecture.

"From day one of our design process, our team has already been thinking solutions to lower impact on the environment. Pulsa made it. This is a project belongs to both nature and itself.” Cary said.
