# Sloping Lakeside Houses The Cedar Park House Features Water-Collecting Roofs By Vasiliki Marapas | Published 2014-10-10 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/cedar-park-house References: [contemporist](http://www.contemporist.com/2014/10/09/cedar-park-house-by-peter-cohan/) & [petercohanarchitect](http://www.petercohanarchitect.com/) Architect Peter Cohan was responsible for the '[Cedar Park House](https://www.trendhunter.com/trends/dune-houses),' located in Seattle, Washington. Exposure to water threatens to derail the home from its precarious position on a slope, meaning the architect had to come up with an energy-efficient way of collecting water before it can do any damage to the foundation. This was done through the use of a water-collecting roof and [cast-concrete walls](https://www.trendhunter.com/trends/omer-arbel). The walls are a defining aspect, as they delineate the interior and exterior and set up the spatial arrangement of the home. More importantly, the Y-shape that the walls create forms a datum against which the site's [slope is calibrated](https://www.trendhunter.com/trends/capuchinas-house). Meanwhile, the water-collecting roof prevents landslides and erosion that can occur on the sloping site, (especially if it becomes water-logged). The roofs have different methods of carrying out their function, with the western roof relocating the water to be drained at street-level, and the eastern roof collecting water in a gable, and then, cistern. ## Trend Insights (Trend Hunter) - Score: 2.6/10 - Popularity: 46% | Activity: 24% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Design](https://www.trendhunter.com/design) ## Key Themes ### What's Driving This Trend - **Water-collecting Roofs:** Innovative water-collecting roofs provide energy-efficient solutions for collecting water and preventing foundation damage. - **Cast-concrete Walls:** Cast-concrete walls define the interior and exterior of a structure while acting as a barrier against sloping site challenges. - **Spatial Arrangement:** The spatial arrangement of a home is optimized through the use of Y-shaped walls that calibrate the site's slope. ### Who This Affects Most - **Architecture:** The architecture industry can leverage the use of water-collecting roofs and cast-concrete walls for sustainable and resilient building designs. - **Construction:** In the construction industry, incorporating innovative water management systems and spatial arrangement techniques can enhance the durability and stability of structures built on slopes. - **Environmental Engineering:** Environmental engineers can explore opportunities to develop advanced systems for managing water flow and erosion in sloping landscapes, contributing to sustainable development. ## Related on Trend Hunter - [Recycling-Centric Waterfront Homes](https://www.trendhunter.com/trends/shor-house.md) - [Stepped Hillside Residences](https://www.trendhunter.com/trends/b2a-architects.md) - [Faceted Cedar Houses](https://www.trendhunter.com/trends/the-house-on-a-hill.md) - [Hillside Embedded Residences](https://www.trendhunter.com/trends/house-in-the-slope.md) - [Flood-Mitigating Wooden Homes](https://www.trendhunter.com/trends/ushijima-architects.md) - [Wooden Clad Jagged Residences](https://www.trendhunter.com/trends/shed-architecture-and-design.md) - [Sloped Site Concrete Residences](https://www.trendhunter.com/trends/oeiras-house.md) - [Cedar-Clad L-Shaped Beach Homes](https://www.trendhunter.com/trends/ospreys-landing.md) - [Mountainside Cedar Alpine Houses](https://www.trendhunter.com/trends/elizabeth-roberts-architects.md)
