This riverside vacation house was designed for a large family whose lives have long been connected to the water. The homeowners grew up in Ayutthaya, a province in Thailand, where rivers have historically shaped local lifestyles and seasonal living patterns. Located along the Chao Phraya River, the house serves as a gathering place for family members from different generations and lifestyles.
The design focuses on simplicity, flexibility, and comfort. The main spaces include an open living and dining area connected to a large riverside terrace, creating spaces for shared family activities. The house contains one ground-floor bedroom for elderly residents and four upper-floor bedrooms for extended family gatherings. A separate Thai kitchen supports the family’s tradition of cooking together.
One of the main challenges of the project was the west-facing riverfront, which receives strong afternoon heat. The house was therefore carefully designed to maintain river views while reducing heat gain and maximizing natural ventilation. Passive design strategies became the core concept of the project.
Inspired by traditional elevated houses of central Thailand, the building is raised above historical flood levels and includes both stairs and wheelchair-accessible ramps. The ground floor was designed as an open, naturally ventilated space with full-height sliding doors that allow indoor and outdoor spaces to connect seamlessly. The upper floor extends outward to create shaded areas below, similar to the atmosphere beneath traditional Thai houses.
All bedrooms are positioned parallel to the river and connected to large semi-outdoor terraces that provide privacy, shading, and outdoor living space. Adjustable timber screens along the facade help control sunlight, ventilation, and privacy while preserving river views. The master bedroom projects closer toward the river to maximize panoramic views and create additional shade for the lower terrace.
A large roof with deep overhangs protects the house from the tropical climate while creating tall, airy interior spaces. Repetitive roof rafters help create a calm and shaded atmosphere throughout the upper floor.
Material selection focused on durability, low maintenance, and suitability for the hot-humid climate. Locally sourced granite, reclaimed timber, and natural ventilation systems were used throughout the project to reduce environmental impact and support long-term use.
Overall, the house was designed as a simple and welcoming family retreat that encourages connection, shared activities, and everyday living close to nature, with the Chao Phraya River forming the backdrop of family life.
