### 4. Latest Equipment Specifications to Enhance Quality of Life

* **Ultrafine Bubbles**

Microbubbles enhance cleaning effects, supporting a daily life of "clean without scrubbing" in water areas throughout the house, including the kitchen and bathroom. Furthermore, during bathing, microbubbles penetrate hair and skin, enhancing beauty and moisturizing effects.

* **Smart Shared Facilities**

Equipped with a non-contact auto-lock system for keyless entry and convenient delivery lockers for receiving packages when away. This achieves both high security and convenience.

* **Functional Storage Planning**

By incorporating SIC (Shoe-in Closets) in all plans, the living space feels more spacious than its actual area, thanks to the know-how in space utilization cultivated in the detached housing business.
