UnionTec and Mountain House Architects Join Forces

UnionTec, a leading company based in Shibuya, Tokyo, known for its comprehensive services in interior design and construction, has made a significant move to expand its portfolio. On March 27, 2026, it announced the incorporation of Mountain House Architects into its group. This strategic alliance is set to enhance the offerings for both national and individual clients, ensuring that they receive top-notch services under one roof.

A New Chapter for Mountain House Architects

Mountain House Architects has built an impressive reputation in various domains, including architecture, interior design, display, and product design. With a strong track record of collaborating with national clients such as Dentsu, Hakuhodo, and Japan Airlines, the firm's expertise has been highly regarded in the market. Joining forces with UnionTec will enable Mountain House Architects to tackle more complex projects that they had previously turned down due to resource limitations. This partnership also facilitates a one-stop service that encompasses not just design but also construction services, ensuring clients' diverse needs are met more effectively.

The Journey of Akira Yambeya

Akira Yambeya, the CEO of Mountain House Architects, is an exemplar of passion and creativity in the field. After graduating from Musashino Art University, he initially pursued a career as a hairstylist before discovering his true calling in architecture during a transformative trip. He has worked on various projects, including interior designs and commercial exhibitions before founding his own company in 2013. His belief in the importance of everyday experiences has guided him in designing spaces that resonate with the lives of those who inhabit them.

UnionTec's Vision and Future

UnionTec's mission is to 'Build a new standard,' and the addition of Mountain House Architects aligns perfectly with this vision. By supporting designers and design firms, UnionTec aims to foster industry growth while ensuring that outstanding solutions are delivered to clients. The company's robust assets, including over 25 years of operational strength and state-of-the-art digital services, will be at the disposal of both firms as they strive to achieve greater success together.

Comments from Leadership

In his remarks, Yambeya expressed his excitement about reaching more clients through this merger. He emphasizes that design should be accessible and relevant to everyday life, stating that joining UnionTec allows him to reach a broader audience with his work. UnionTec's CEO, Yusuke Okawa, echoed these sentiments, highlighting the mutual benefits of this partnership and expressing enthusiasm for the increased value it will bring to their clients and staff alike.

Looking Ahead

With this merger, UnionTec is poised to further expand its influence in the field of space production, aiming to collaborate with trusted designers and firms to elevate industry standards. UnionTec will continue investing in innovative technologies and approaches to support both national clients and individual designers.

As part of their ongoing commitment to the industry, UnionTec will allow designers, contractors, and production companies access to its resources, ensuring they can focus on what they love while expanding their reach and profitability. This includes offering one-stop services from design to execution for a smoother operational process.

As they navigate this new chapter, both UnionTec and Mountain House Architects are excited to explore synergies and create new opportunities within the design and construction industries.
