What makes this building stand apart is the 12 [open-air rooms](https://www.trendhunter.com/trends/anchor-house), which enhance [natural light and ventilation](https://www.trendhunter.com/trends/house-in-corjeum). There are seven apartments within, three of which are located on the ground floor. The other four are allocated over the two upper levels. The open rooms, as the architects refer to them, are scattered throughout each floor. Though they are protected by the roof, each room features a window without glazing. The rooms are intended as an exploration of indoor and outdoor spaces; however, they also provide the residents with a naturally-lit area to use in the spirit of play. ## Trend Insights (Trend Hunter) - Score: 2.9/10 - Popularity: 54% | Activity: 26% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Design](https://www.trendhunter.com/design) ## Key Themes ### Why This Trend Is Growing - **Open-air Living Spaces:** Opportunity for designers and architects to create innovative buildings that incorporate open-air rooms for enhanced natural light and ventilation. - **Exploration of Indoor and Outdoor Spaces:** Potential for interior designers to create seamless transitions between indoor and outdoor areas to enhance the living experience. - **Naturally-lit Areas for Play:** Possibility for entrepreneurs to develop creative and interactive spaces that utilize natural light for recreational purposes. ### Industries Being Reshaped - **Architecture:** Disruptive opportunity for architects to reimagine building design by incorporating open-air rooms for improved natural light and ventilation. - **Interior Design:** Innovation potential for interior designers to create seamless connections between indoor and outdoor spaces, transforming the way people live. - **Recreation and Entertainment:** Opportunity for entrepreneurs to capitalize on the growing trend of naturally-lit spaces for play, offering unique and engaging recreational experiences. ## Related on Trend Hunter - [Adjustable Japanese Studio Apartments](https://www.trendhunter.com/trends/building-frame-of-the-house.md) - [Wooden Screen Apartment Blocks](https://www.trendhunter.com/trends/ohlab.md) - [Multifunctional Angled Apartments](https://www.trendhunter.com/trends/vertikal-nydalen.md) - [Naturally Ventilated Bright Houses](https://www.trendhunter.com/trends/pott-house.md) - [Terraced Urban Residences](https://www.trendhunter.com/trends/house-in-minamiazabu.md) - [Bright Urban Apartments](https://www.trendhunter.com/trends/house-64.md) - [Natural Light-Based Buildings](https://www.trendhunter.com/trends/house-of-voids.md) - [Ever-Changing Japanese Houses](https://www.trendhunter.com/trends/kumagaya-house.md) - [Clear Glazing Compact Residences](https://www.trendhunter.com/trends/check-patterned-house.md)
