Mold," "algae," and "moss" can quickly proliferate as long as there is moisture. For those who are good at maintenance, the most effective method is to remove them as soon as they are spotted!

The floor vent is essential for underfloor heating. Many construction companies have the concern, "Isn't it strange that only the vent is made of a different material?" We developed an original solution to address this issue. -------------------------------- The essential item for foundation insulation and underfloor heating is the "floor vent"! This ventilation component equalizes the temperature between the underfloor and the room, and it is a must-have item when installing underfloor air conditioning or heating. Although it plays a supporting role, it is one of the very important components. However, many are made of metal or plastic, which can hinder the natural interior design. Instead of just accepting it, what if there was a vent made of the same material? This led to the creation of the "Oaks Slit," a floor vent that has never existed before, born from such concerns.

Gravel Paving Material: Gravel Fix Chiba Prefecture, Kisarazu City, Kaneda Community Exchange Center The center is located in an area adjacent to a large outlet park, where the surrounding environment has undergone significant development, making the aesthetics of the buildings a major consideration. Simply using asphalt or gravel would feel "bland," so the entrance and parking lot are enhanced by the gentle touch of natural materials. We planned a "gravel road." As a community exchange center frequented by many people, including wheelchair users and women in high heels, the phrase "won't sink even on gravel" is particularly fitting. Additionally, due to the local characteristics, another decisive factor was the "drainage capability." This design also took into account disaster prevention measures in the event of an earthquake. They wanted to ensure proper drainage based on the ground's characteristics, and resolving this issue has become a significant advantage. The representatives from Kisarazu City Hall have also clearly understood the characteristics of Gravel Fix, and we received positive feedback that it perfectly aligns with the concept of "connecting the sea, town, people, and future."
