The project is dubbed Plug-in City 75. Since the vintage construction of the building fails to subscribe to the notions of sustainability and eco-friendly living, Malka Architecture provides the proposal for the energy efficiency improvement via the [responsibly sourced wooden modular boxes](https://www.trendhunter.com/trends/modular-offgrid-house). However, the extensions will also be tailored to the needs and wants of each resident. This will ultimately provide the building's units with additional space. The 1970s Parisian apartment complex will not only display a quarter of its previous energy consumption, but it will also undergo aesthetic changes as the modular parasitic extensions offer the option for the building to be [draped in greenery](https://www.trendhunter.com/trends/hope-villa). ## Trend Insights (Trend Hunter) - Score: 4.4/10 - Popularity: 71% | Activity: 53% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) > [Eco Architecture](https://www.trendhunter.com/ecoarchitecture) ## Key Themes ### Why This Trend Is Growing - **Energy Efficiency Improvement:** The proposal for attaching boxy parasitic extensions to existing buildings presents a disruptive innovation opportunity for improving energy efficiency. - **Responsibly Sourced Materials:** The use of responsibly sourced wooden modular boxes in building extensions creates an opportunity for sustainable construction practices. - **Modular Architecture:** The concept of attaching modular parasitic extensions to existing structures opens up possibilities for flexible and customizable living spaces. ### Industries Being Reshaped - **Architecture:** The architecture industry can explore new design techniques and construction methods for attaching boxy parasitic extensions to improve energy efficiency and sustainability. - **Construction:** The construction industry has the opportunity to develop prefabricated modular units and installation processes for attaching parasitic extensions to existing buildings. - **Renewable Energy:** The renewable energy industry can benefit from integrating energy-efficient systems and sustainable materials in the design and construction of parasitic extensions. ## Related on Trend Hunter - [Tropical Modern House Extensions](https://www.trendhunter.com/trends/plaster-house.md) - [Compact Residential Additions](https://www.trendhunter.com/trends/henville-street-house.md) - [Elongated London Courtyard Houses](https://www.trendhunter.com/trends/blythe-hill-house.md) - [Box-Like Innovative Apartment Designs](https://www.trendhunter.com/trends/innovative-apartment-design.md) - [Sustainable Family Homes](https://www.trendhunter.com/trends/twin-pitches.md) - [Craftsmanship-Based Home Extensions](https://www.trendhunter.com/trends/ray-house-extension.md) - [Retro Gabled Greenhouse Additions](https://www.trendhunter.com/trends/casa-wiz.md) - [Plinth Wall Contemporary Extensions](https://www.trendhunter.com/trends/plinth-house.md) - [Vibrant London Home Extensions](https://www.trendhunter.com/trends/park-house.md)
