The Dutch firm was tasked with making the most of a [concrete World War II military bunker](https://www.trendhunter.com/trends/alastair-philip-wiper) in the middle of a quaint neighborhood. Rather than simply demolishing it, Froscen Architects rose to the challenge. Its design solution was to build [micro homes](https://www.trendhunter.com/trends/bth-loft) on top of the brutalist bunkers. The four small homes are each just 38 square meters, but Froscen manages to fill that limited space with a double bedroom, a lounge, a kitchen and a bathroom. The houses combine modern architectural style with the history of the Dutch city, preserving an important part of the foundation that makes up Leiden. ## Trend Insights (Trend Hunter) - Score: 3.2/10 - Popularity: 54% | Activity: 35% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: 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 ### What's Driving This Trend - **Micro Homes:** Micro homes on top of existing structures such as bunkers offer unique solutions to maximize limited space. - **Preservation Architecture:** Combining modern architectural style with historic landmarks, such as WWII bunkers, creates a unique and meaningful living space. - **Adaptive Reuse:** Transforming military or industrial structures into residential living spaces offers sustainable and unique real estate opportunities. ### Who This Affects Most - **Real Estate:** Real estate industry professionals can use innovative design solutions such as micro homes to maximize valuable city space where standard homes may not be an option. - **Architecture:** Architects can utilize historic landmarks and existing structures, such as WWII bunkers, to create unique residential living spaces that blend old and new architectural styles. - **Construction:** Construction industry professionals can apply adaptive reuse techniques to transform industrial or military structures into modern residential spaces, creating a sustainable and repurposed living environment. ## Related on Trend Hunter - [Military Base-Transformed Housing](https://www.trendhunter.com/trends/buitenplaats-koningsweg.md) - [Bunker-Converted Holiday Homes](https://www.trendhunter.com/trends/corstorphine-wright.md) - [Underground Autonomous Shelter](https://www.trendhunter.com/trends/plan-b-1.md) - [Angular Stealthy Holiday Retreats](https://www.trendhunter.com/trends/stay-under-the-radar.md) - [Prefabricated Miniature Home Concepts](https://www.trendhunter.com/trends/cpsula.md) - [Partially Buried Tranquil Retreats](https://www.trendhunter.com/trends/house-under-the-ground.md) - [Compact Refurbished Micro-Homes](https://www.trendhunter.com/trends/sassi.md) - [Blocky Extended Transformed Bunaglows](https://www.trendhunter.com/trends/osullivan-skoufoglou-architects.md) - [War Plane-Inspired Off-Grid Homes](https://www.trendhunter.com/trends/monocoque-cabin.md)
