项目 - S design farm通过他们创新的"增减之家"，重新定义了住宅设计。这座位于千叶的近85平米住宅，在后疫情时代对建筑富足性提出了独特的思考。

受到对繁荣本质深刻哲学探讨的驱动，建筑师巧妙地平衡了"增加的丰富"和"减少的丰富"。这个项目作为建筑创新的杰出范例，展示了如何在不断上涨的建设成本和不断演变的居住期望中超越空间限制。

该住宅最引人注目的特点是其非传统的"户外起居"空间——本质上是一个部分连接室内的掏空区域。这种巧妙的设计创造了一个半可控的外部区域，拥抱不可预测性，允许与自然即兴的互动，从意外的野生动物访客到随意的篝火聚会。

从技术上看，房屋通过精细的设计策略实现了高性能可持续性。采用顶级热绝缘（6级）、三层玻璃窗，以及6kW太阳能发电系统，该住宅实现了接近零能耗，同时保持了卓越的室内舒适度。建筑师报告称，全年室内温度稳定在20-25°C，能源消耗极低。

通过有意将室内空间限制在65平方米，并设置33平方米的阁楼，这个设计体现了对空间效率的微妙处理。建筑师们优先考虑创造情感的充沛感，证明建筑质量超越了物理尺寸。

这个住宅原型不仅仅是一个家——它是当代生活的宣言，向设计师和居民发起声明，通过深思熟虑的、可持续的设计重新想象“繁荣的概念”。

团队 – S Design Farm成立于2008年，在首席建筑师鹿内健（Takeshi Shikauchi）的领导下，致力于打造融合可持续性、舒适性与建筑创新的空间。作为总部位于东京的一级建筑事务所，S Design Farm以设计高性能、节能环保住宅和充满灵感的室内空间而闻名，其设计理念强调平衡——在追求高效保温性和气密性的同时，不牺牲建筑与自然环境的和谐关系。

在鹿内健的带领下，这家公司屡获殊荣，其团队最近的代表作“增减之家”（Addition and Subtraction House）荣获2023亚洲设计大奖金奖，并入围2023 ArchDaily年度建筑奖提名。此外，“瀑布别墅”（Waterfall Villa）也因其豪华与可持续设计理念在国际上备受赞誉。

S Design Farm专注于定制住宅设计和全方位翻新项目，采用前沿技术实现ZEH（净零能源住宅）标准，甚至设计出几乎无需供暖的建筑。他们不仅追求技术性能的卓越，更注重通过建筑设计捕捉自然的细微变化，创造能丰富居住者生活的空间。S Design Farm以每一个项目为例，展现了卓越的专业精神，塑造出功能与灵感兼具的建筑典范。

Project - Japanese architects Kuki Health and Masako Kuki of S Design Firm have redefined residential design with their innovative " Addition and Subtraction House," a compact 65-square-meter (interior) home in Chiba that challenges conventional notions of architectural richness during the post-pandemic era.

Driven by a profound philosophical inquiry into the essence of prosperity, the architects have crafted a dwelling that masterfully balances "enrichment through addition" and "enrichment through subtraction." The project emerges as a sophisticated response to rising construction costs and evolving domestic expectations, demonstrating how architectural innovation can transcend spatial limitations.

The home's most striking feature is its unconventional "outdoor living" space—essentially a hollowed-out area that remains partially connected to the interior. This ingenious design creates a semi-controlled exterior zone that embraces unpredictability, allowing spontaneous interactions with nature, from unexpected wildlife visitors to casual moments like impromptu fire pit gatherings.

Technically exceptional, the house achieves high-performance sustainability through meticulous design strategies. Featuring top-tier thermal insulation (Grade 6), triple-glazed windows, and a 6kW solar power system, the residence achieves near-zero energy consumption while maintaining exceptional indoor comfort. The architects report maintaining stable indoor temperatures between 20-25°C year-round with minimal energy expenditure.

By deliberately constraining the interior to 65 square meters and incorporating a 33-square-meter loft, the design exemplifies a nuanced approach to spatial efficiency. The architects prioritized creating emotional richness over pure square footage, proving that architectural quality transcends physical dimensions.

This residential prototype represents more than just a home—it's a manifesto on contemporary living, challenging architects and inhabitants to reimagine prosperity through thoughtful, sustainable design.
