项目 - 日本建筑事务所堤由匡建筑设计工作室（TSUTSUMI & ASSOCIATES）在北京完成了"HOUSE X"项目——一处经过精心改造的私人住宅。该项目通过自然采光和通风的视角重新诠释了无障碍设计的概念。这座面积为235平方米的住宅，突破了传统无障碍生活空间的设计方法，将阳光和气流视为通用设计的基本要素。

这个于2024年5月竣工的项目，将一个原本黑暗、带有欧式官邸风格台阶的住所，改造成了一个明亮流畅的空间，完美适应三代人的共同生活需求。这次改造是应一位50多岁的业主委托进行的，因为他与年迈的父母共同居住，这促使建筑师堤由匡开发出一种突破传统解决方案的创新无障碍设计方法。

"我们认为，让健康的光线和舒适的微风在室内自由流动，才是最终极的无障碍设计，"堤由匡如是解释。这一理念通过多种实用的设计干预得以实现，例如将客厅地面抬高30厘米以创造统一的生活空间水平面，同时巧妙地融入下沉式座椅区，使其兼具咖啡区功能。

项目最引人注目的特色或许是那个具有日式风格的户外浴场，它通过木质走廊与主卧浴室相连。浴场展现了设计工作室对隐私与开放性的细腻处理——下部保持开放，而腰部以上则用木质推拉门环绕。屋顶的倾斜百叶既能遮挡来自上方的视线，又保持了与天空的联系。

在整个项目中，传统的无障碍元素都被赋予了建筑学的优雅特质。扶手兼具照明功能，避免了辅助生活空间常见的机构化美学特征。推拉门的设计考虑到轮椅通行需求，而贯通式厕所则为未来的护理需求提供便利，同时不影响设计的完整性。

事务所对自然采光和通风的重视，直接回应了他们认为的住宅开发中的普遍问题——过分重视建筑面积而忽视环境品质。通过将所有浴室布置在外墙，并设置多个推拉门，设计确保日光可以深入渗透到生活空间，同时促进自然通风。

这种将无障碍设计与空间氛围质量相结合的整体性方法，显着区别于传统的无障碍建筑，为中国城市多代同堂的生活空间提供了一个新范式。

团队 - 堤由匡建筑设计工作室由堤由匡（1978年生）于2009年在北京创立，现已发展成为一家在东京和北京均设有办公室的国际知名建筑事务所。作为一级建筑师事务所，该事务所成功地在日本建筑精密性与中国当代城市发展之间架起了独特的桥梁。

堤由匡2003年毕业于东京大学建筑学科，随后在SAKO建筑设计工社（2004-2008）积累了丰富的专业经验，之后创立了自己的建筑事务所。事务所的发展轨迹标志性地经历了战略性扩张，先后于2020年在广岛开设办公室，并于2022年迁至东京。

事务所的作品获得了众多国际重要奖项的认可，包括日本JCD设计大奖金奖、银奖和西泽立卫奖，香港DFA大奖银奖，以及来自全球性竞赛的荣誉，如美国建筑大师奖（The Architecture MasterPrize）和意大利A' Design Award银奖。他们的作品以空间效率的精妙整合、文化敏感性和创新的无障碍解决方案著称，这些特点在其遍布亚洲的住宅和商业项目中尤为突出。

事务所现同时运营两个战略据点——位于板桥区的东京总部和位于朝阳区的北京办公室。堤由匡建筑设计工作室持续扩大其在全球建筑领域的影响力，专注于开发能够连接东西方建筑范式的场域响应式设计解决方案。

Project Name: HOUSE X - Universal Design Residence with an Outdoor Bath

Location: Beijing, China

Design Team: TSUTSUMI & ASSOCIATES

Feature：

Project - Japanese architecture firm TSUTSUMI & ASSOCIATES has completed HOUSE X, a thoughtfully renovated ground-floor apartment in Beijing that reimagines barrier-free design through the lens of natural light and ventilation. The 235-square-meter residence challenges conventional approaches to accessible living spaces by treating sunlight and airflow as fundamental aspects of universal design.

The project, which was completed in May 2024, transforms a previously dark apartment with European mansion-inspired level changes into a luminous, fluid space that seamlessly accommodates three generations. The renovation was commissioned by a client in his 50s who lives with his elderly parents, prompting architect Yoshimasa Tsutsumi to develop an innovative approach to accessibility that goes beyond standard solutions.

"We believe that healthy light and pleasant breezes moving freely within the home represent the ultimate form of barrier-free design," explains Tsutsumi. This philosophy manifests in practical interventions, such as raising the living room floor by 30 centimeters to create a unified level throughout the main living spaces, while cleverly incorporating a sunken seating area that doubles as a coffee space.

The most striking feature is perhaps the Japanese-inspired outdoor bath, connected to the main bedroom's bathroom via a wooden corridor. The bathing area demonstrates the studio's nuanced approach to privacy and openness – its lower section remains open while wooden sliding doors enclose the space from waist height. Angled louvers in the roof structure shield from overlooking views while maintaining a sense of connection with the sky.

Throughout the apartment, conventional accessibility elements are reimagined with architectural sophistication. Handrails double as lighting fixtures, avoiding the institutional aesthetic often associated with assisted living spaces. Sliding doors are designed to accommodate wheelchair access, while a walk-through toilet anticipates future caregiving needs without compromising on design integrity.

The firm's emphasis on natural light and ventilation responds directly to what they identify as a common problem in Chinese residential developments – the tendency to prioritize floor area at the expense of environmental quality. By positioning all bathrooms along exterior walls and incorporating numerous sliding doors, the design ensures that daylight penetrates deep into the living spaces while facilitating cross-ventilation.

This holistic approach to universal design, where accessibility meets atmospheric quality, represents a significant departure from conventional barrier-free architecture, offering a new paradigm for multi-generational living spaces in urban China.

Design Team - Founded in 2009 in Beijing by Yoshimasa Tsutsumi (born 1978 in Fukuoka), TSUTSUMI & ASSOCIATES has evolved into a distinguished international architectural practice with offices in both Tokyo and Beijing. The practice, officially registered as a First-Class Architectural Firm (Tokyo Governor Registration No. 65108), represents a unique bridge between Japanese architectural precision and contemporary Chinese urban development.

Tsutsumi, who graduated from the University of Tokyo's Department of Architecture in 2003, refined his expertise at SAKO Architects (2004-2008) before establishing his own practice. The firm's trajectory has been marked by strategic expansion, with the opening of a Hiroshima office in 2020 and relocation to Tokyo in 2022.

The studio's portfolio has garnered international recognition through numerous prestigious awards, including the JCD Design Award Gold and Silver Medals and the Ryue Nishizawa Prize in Japan, the DFA Award Silver Prize in Hong Kong, and distinctions from global competitions such as The Architecture MasterPrize (USA) and A' Design Award Silver Prize (Italy). Their work is characterized by a sophisticated integration of spatial efficiency, cultural sensitivity, and innovative barrier-free solutions, particularly evident in residential and commercial projects across Asia.

Operating from two strategic locations - their Tokyo headquarters in Itabashi and their Beijing office in Chaoyang District - TSUTSUMI & ASSOCIATES continues to expand its influence in the global architectural landscape, specializing in context-responsive design solutions that bridge Eastern and Western architectural paradigms.
