# Public Hammock Houses Flederhaus by Heri & Salli is a Vertical Park of Repose By Amelia Roblin | Published 2011-07-11 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/flederhaus-by-heri-salli References: [dvice](http://dvice.com/archives/2011/07/come-hang-out-i.php) & [archdaily](http://www.archdaily.com/148401/flederhaus-heri-salli/) In general the vertical hierarchy of the urban environment opens the lower levels of buildings and outdoor spaces to the public, but the Flederhaus by Heri & Salli changes this dramatically. Of course, this particular project is probably unlike anything you've ever seen. The four-storey plus attic structure takes the form of a conventional house with a [pitched roof](https://www.trendhunter.com/trends/frame-house-1), leaving its front and back facades enclosed only by guardrails on each floor. Most compellingly, the [metropolitan installation](https://www.trendhunter.com/trends/host) in Vienna, Austria, contains [clusters of hammocks](https://www.trendhunter.com/trends/anymaka-hammock-tent) so that park-goers can climb its steps and kick back in one of these suspended day sleepers. Offering a vast view of the surrounding architecture and greenery, the Flederhaus by Heri & Salli holds around 30 separate slings. ## Trend Insights (Trend Hunter) - Score: 6.4/10 - Popularity: 93% | Activity: 92% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe ## 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 - **Vertical Park Spaces:** Creating multi-level park spaces that offer unique and immersive leisure experiences. - **Urban Hammock Installations:** Incorporating hammocks into urban structures for relaxation and enjoyment. - **Open-air Architecture:** Designing buildings with open facades and elevated platforms for public use. ### Industries Being Reshaped - **Architecture:** Innovating the design and construction of urban spaces to include public hammock installations. - **Leisure and Recreation:** Developing unique and relaxing experiences within urban environments through the creation of vertical park spaces. - **Tourism and Hospitality:** Integrating hammock installations into hotels, resorts, and other tourist attractions to attract visitors seeking leisure and relaxation. ## Related on Trend Hunter - [Tranquil Suspended Hanging Retreats](https://www.trendhunter.com/trends/ardh-architect.md) - [Stilts-Reading Suspended Homes](https://www.trendhunter.com/trends/the-hole-with-the-house-around.md) - [Inversion Living Concepts](https://www.trendhunter.com/trends/tiny-getaway.md) - [Vertical Feline Residences](https://www.trendhunter.com/trends/cat-tree-house-2.md) - [Geometric Timber Holiday Cabins](https://www.trendhunter.com/trends/amunt.md) - [Cartoonish Tubular Treehouses](https://www.trendhunter.com/trends/tubular-treehouse.md) - [Elevated Treetop Modern Cabins](https://www.trendhunter.com/trends/buitenverblijf-nest.md) - [Nature-Shared A-Frame Homes](https://www.trendhunter.com/trends/kumiki-architects.md) - [Elevated Garden Lofts](https://www.trendhunter.com/trends/attic-above-garden.md)
