Revolutionizing Home Construction: The Launch of TATETA by Open House Architect

TATETA: Your Home Builder in Animation



Open House Architect, a leading construction company based in Nakano, Tokyo, has announced the launch of a groundbreaking app called TATETA. This innovative application aims to transform the home construction process by visualizing it through engaging animations, bringing new experiences to homeowners.

The TATETA service represents a significant evolution in how customers can interact with the building process. Leveraging advanced IT technologies cultivated through Open House Architect's self-developed construction management app, Architect Jump, TATETA marks a shift towards providing a unique user experience. For the first time, homeowners will witness the progression of their house being built in real time, experienced through a social network-like animation.

Addressing Homeowner Concerns



Traditionally, homeowners have had limited ways to track their home's construction status. They could either visit the construction site or rely on photos received from their builder. However, with an increasing number of double-income households and diverse lifestyles, frequent site visits are often impractical. As a result, the uncertainty of not knowing the construction progress has been a significant source of anxiety.

Open House Architect has been addressing this issue through the digitization of construction sites. The Architect Jump app has resulted in a 13% reduction in construction time and an 80% decrease in rework costs, enhancing productivity significantly. With TATETA, this real-time data will now be channeled into a communication tool aimed at homeowners, bringing transparency and ease to the construction process. The application creates a welcoming environment, illustrating the precise progression of construction through appealing animations, giving busy homeowners a sense of assurance and excitement.

Main Features of TATETA



1. Visualizing Your Home's Growth


TATETA utilizes illustrations to simulate the construction process based on the unique features of each homeowner's property, such as roof styles, house shapes, colors, number of floors, and the presence of balconies. As the construction progresses through nine stages—from the onset to handover—tiny illustrations and backgrounds evolve, while carpenters and contractors are depicted in a playful manner that fosters a connection with the builders.

2. Real-Time Updates with Photo Albums


Homeowners can track the latest developments through an “At-Home Album,” where site managers share real-time photographs, ensuring that customers can stay informed without needing to physically visit the site.

3. Easy-to-Understand Project Explanations


For those lacking construction knowledge, TATETA simplifies the learning curve. By tapping a “?” icon on the animation, users can access clear, visually-supported explanations of the ongoing works, allowing homeowners to transform their worries into understanding and confidence.

4. Convenient Management of Property Documentation


All essential property documents shared by Open House Architect are easily accessible within the app. Homeowners can download these materials at their convenience, streamlining the management of necessary paperwork.

5. Sharing Milestones on Social Media


TATETA includes a feature enabling customers to share progress updates on social media, allowing them to easily engage with family and friends about their home-building journey.

Looking Ahead


In the future, Open House Architect plans to extend TATETA's features to real estate companies for the progress tracking of spec homes, ensuring transparency for end-users and further enhancing trust in the construction process.

The company is committed to leveraging IT advancements to elevate the customer experience, enabling all clients to enjoy the emotional journey of building their homes, encapsulated in their mission: "Innovation in Construction."
