The villa was built using local labor and utilizing concrete, sandstone, timber and [sustainably grown teak](https://www.trendhunter.com/trends/casa-guaec-project) for the furniture and flooring. The villa is oriented north-to-south, which helps reduce solar heat gain and keeps the sun on the swimming pool for much of the day to keep it warm; a [solar panel heating system](https://www.trendhunter.com/trends/casa-girasol) is also on hand to keep the pool water warm. Casa 7A also features a ventilated roof and catchment system which collects rainwater which can be used for irrigation. The most interesting design feature of the residence is the semi-outdoor living space. The space is open and doesn't have walls, but timber screens can be slid across to close off the home when privacy is needed. ## Trend Insights (Trend Hunter) - Score: 5.9/10 - Popularity: 85% | Activity: 83% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: South America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) > [Eco Architecture](https://www.trendhunter.com/ecoarchitecture) ## Key Themes ### Key Themes Behind This Trend - **Sustainable Villas:** There is an opportunity to create more sustainable and environmentally-friendly luxurious villas around the world using local labor and sustainably sourced materials. - **Solar Heating Systems for Pools:** Incorporating solar heating systems into swimming pools provides an environmentally-friendly way to keep the water warm and reduce costs. - **Ventilated Roofs and Rainwater Catchment Systems:** Designing homes with ventilated roofs and rainwater catchment systems can help reduce water usage and decrease the ecological footprint of residential properties. ### Where This Applies - **Luxury Real Estate:** Luxury real estate developers can explore incorporating sustainable design features and materials into their properties to attract environmentally-conscious consumers. - **Solar Energy:** Solar energy companies can explore opportunities to provide solar heating systems specifically for swimming pools, which could potentially become a popular sustainable home feature. - **Architecture and Construction:** Architecture and construction companies can focus on developing innovative sustainable designs and construction techniques to create eco-friendly homes and villas with a luxurious feel. ## Related on Trend Hunter - [Mountain-Top Tranquil Homes](https://www.trendhunter.com/trends/casa-aire.md) - [Sustainable Canopy Pavilions](https://www.trendhunter.com/trends/casa-solai.md) - [Patio-Centering Villa Designs](https://www.trendhunter.com/trends/casa-tres-patis.md) - [Nature-Connecting Tranquil Homes](https://www.trendhunter.com/trends/al-suave-house.md) - [Sustainable Dome Villas](https://www.trendhunter.com/trends/belalu-dome-villa.md) - [Climate-Generating Skylight Homes](https://www.trendhunter.com/trends/casa-con-lucarna.md) - [Cliffside Minimalist Retreats](https://www.trendhunter.com/trends/aip-azia-villa.md) - [Landscape-Integrated Hill Homes](https://www.trendhunter.com/trends/casa-av.md) - [Hillside Concrete Retreats](https://www.trendhunter.com/trends/concrete-house-1.md)
