Polish based design studio Superhelix creates a green roof masterpiece that not only highlights the home's ecological design, but showcases what happens to buildings when they change over time. Located in Krakow, Poland the 189 square meter home's slanted roof was not built for aesthetics, but instead was constructed due to a building requirement. Due to local building codes, the home's roof had to be built at a 45-degree slope. To some this may have been a design obstacle, but to Bartłomiej Drabik, principal architect, he used this as an opportunity to create a progressive roof design that highlights green design.

Through out the construction of this residential home, special attention was emphasized on how the building's materials will allow the home to age and change naturally. The home's elevation was covered with western red cedar planks. This particular wood type does not require wood treatment against insects and the weather. As the wood ages over time, it will transition from a rich reddish brown, to a silver gray tone. Another impressive design element is the overall maintenance of the green roof. 

The southern roof is lined with photovoltaic cells that absorb sunlight and store it for energy, while the northern roof is covered succulents to provide a low maintenance base for the green roof. Thanks to the location of the of the home, the succulents that are planted on the green roof do not require watering. The plant's natural water retention capabilities are not an issue for long dry periods. 

Due to the development of Krakow as a city, several natural areas are often used for building developments. Projects like this help stress the importance of designing a home with an ecological approach. The home's location was another factor that not only enhances it's curb appeal but also reaffirms the use of adding to the surrounding area, not taking away landscape views.

"House behind the Roof" works with several design techniques to showcase progressive green design.
