Amid rapid transformation in the construction and real estate industry, Sansiri continues to advance a new business model that comprehensively addresses evolving consumer needs including an expansion into custom home building on customers’ own land, under the brand Tonbabb Crafted by Sansiri. This initiative reflects Sansiri’s core strengths in design, construction standards, and proprietary Precast structural panel technology.
Mr. Arnut Kittikulmetee, Senior Executive Vice President Project Development Department (Low Rise), shares his vision for this business and Sansiri’s role at Architect’26, one of the region’s most significant platforms for design and construction.
Design and Construction Systems, United as a New Kind of Home Builder
The idea behind Tonbabb Crafted by Sansiri was born from a simple observation: visitors to Sansiri’s projects would frequently ask whether they could build the same home design on their own land. From that recurring question, Sansiri identified a clear market gap customers who already own land and want quality design with flexible functionality.
The result is a home-building business that integrates Sansiri’s design capabilities, brand strength, and construction systems into a single offering. Today, the company offers over 100 home designs with show homes available for viewing, built using Sansiri’s own Precast construction system ensuring consistent quality control, on-time delivery, and reduced dependency on on-site labor.
Elevating Construction with Automated Precast — Defect Reduction Starts at the Factory
Architect’26 marks the official public launch of Tonbabb Crafted by Sansiri, alongside a showcase of Precast construction technology powered by German automated machinery. This system delivers high manufacturing precision, minimizes defects, and incorporates a joint system engineered to prevent leakage comprehensively.
Sansiri views the Architect exhibition as a vital platform that brings together every stakeholder in the construction ecosystem — architects, engineers, contractors, material suppliers, technology providers, and consumers.
One-Stop Service Confidence at Every Stage of Building
The custom home business serves two core customer groups. The B2C segment comprises individual landowners seeking to build homes with budgets ranging from approximately THB 3 million to over THB 20 million, covering usable areas from 150 to over 1,000 square meters. The B2B segment includes small developers and landowners looking to build homes for sale as small-scale projects.
Sansiri’s own Precast Factory — equipped with German-standard production technology and the first in its category to receive ISO certification — produces to each customer’s specific requirements, not off-the-shelf. Customers can define their own dimensions and design. This advanced production system reduces construction time, improves accuracy, and enhances efficiency at every stage, supporting business growth while keeping costs well managed — a true end-to-end service.
Key reasons customers choose Sansiri include brand trust built over 40 years in real estate, a factory-controlled construction system with verifiable quality, on-time delivery, actual show homes to visit, and comprehensive One-Stop Service covering consultation, design, construction, and post-sale warranty.
Elevating Living Standards with Health-Conscious Design
Sansiri applies Wellness Architecture across both Biomedical and Building Science dimensions. On the Biomedical side, the company has developed a dust-free home system with multi-stage air filtration to reduce PM2.5 and improve indoor air quality, complemented by tinted glass for glare reduction, heat-reflective paint, organic low-VOC paints, Universal Design for elderly residents, and building orientation optimized for natural ventilation and daylight.
On the Building Science side, the Precast factory system reduces material waste and resource consumption, supporting Green Living and Sustainable Home principles concepts Sansiri has delivered concretely across multiple projects.
Building Consumer Confidence Through Factory-Controlled Construction
Sansiri believes that serious adoption of factory-based construction technology is fundamental to raising the standard of the home-building industry reducing quality control difficulties, lowering the risk of project abandonment, and building genuine consumer confidence.
The Precast system also shortens construction timelines, reduces defects, and supports environmental sustainability fully aligned with the long-term direction of responsible construction industry development.
Highlights at Architect’26: Modern French Renaissance and Beyond
Sansiri’s headline moment at Architect’26 is the world premiere of two new home designs: “Modern French Renaissance” and “Regency Revival” — distinctive European-style homes accommodating usable areas from approximately 400 to over 1,000 square meters. The booth will also feature a live showcase of Precast construction innovation, exclusive in-event promotions, and financial planning consultation services in partnership with affiliated banks — helping customers make their home-building decisions with greater confidence.
Because building a home is a long-term commitment, Sansiri is ready to be the partner that makes it reassuring, comfortable, and sustainable — from the very first day to the day you move in.
Sansiri invites architects, designers, engineers, developers, and anyone planning to build on their own land to experience construction innovation, quality standards, and a holistic approach to living at Booth D103 at Architect’26—the 38th THE ASEAN’S LARGEST BUILDING TECHNOLOGY EXPOSITION taking place from April 28 – May 3, 2026, from 10:00 AM – 8:00 PM at IMPACT Challenger Hall 1–3, Muang Thong Thani.
