For General Users: Building a Home Without Fail - Additive-Free Housing Edition

We will help you create cute homes that are popular among women in the "niche" of additive-free housing! We will give you a collection of case studies featuring numerous photos of construction examples from our agents!

This document is a collection of case studies summarizing examples of niche construction in additive-free homes. It features high-quality construction examples gathered from 170 agencies nationwide. Kitchens, toilets, washrooms, and bathrooms are essential for daily living. The "niche" summarized in this case study is not something that is absolutely necessary for a home! However, depending on the installation location and design, it can become a convenient point for daily life, an eye-catching feature for guests, or a charming aspect that adds a "cute" feeling to everyday living. To create a niche, it is recommended to use an interior wall rather than a wall facing the exterior. Please feel free to inquire for more details. * We are currently recruiting agencies nationwide!
