Folded Roof Structure Featuring Grass Cover and Reinforced Concrete in a Community Café Setting

Project in-detail

The architectural design incorporates a folded roof structure and grass cover, utilizing reinforced concrete and laminated veneer lumber to create a functional community café that integrates seamlessly with the volcanic landscape of Iceland.
5 key facts about this project
01
Utilizes a folded roof structure to enhance rainwater collection and thermal performance.
02
Incorporates grass covering to blend the building with the surrounding volcanic landscape.
03
Features laminated veneer lumber for structural support and reduced environmental impact.
04
Designed with extensive glass panels to maximize natural light and views of the landscape.
05
Serves as a multifunctional community space, promoting social interaction and environmental awareness.
The Folded-Roof Turfhouse is an architectural project situated near the Hverfjall volcano in Iceland. Designed to function as a coffee shop, the structure embodies a blend of modern aesthetics and traditional Icelandic architectural methods. The primary objective of this project is to create a communal space that resonates with the surrounding landscape while providing shelter and comfort to visitors. The design prioritizes thermal efficiency and environmental integration, making it suitable for the region's climate.

The most defining characteristic of the Folded-Roof Turfhouse is its unique roof structure, which features folded surfaces that mimic the natural topography of the volcanic landscape. This geometric design not only aids in rainwater drainage but also enhances the building's thermal performance, addressing the local climate's demands. The incorporation of traditional elements, such as a grass-covered roof, further connects the modern structure with historical Icelandic architecture, promoting sustainability and ecological awareness.

The project utilizes a material palette that consists of reinforced concrete, laminated veneer lumber, glass, and grass. Reinforced concrete ensures durability and structural integrity, while laminated veneer lumber offers a lightweight yet strong alternative for beams. Glass is employed for extensive fenestration, maximizing natural light and providing panoramic views of the volcanic landscape. The grass roof enhances insulation while blending the structure with its environment.

Inside, the layout is organized to accommodate multiple functions including a café, exhibition space, and flexible work areas. The design fosters interaction among visitors, creating a welcoming environment. Large windows and skylights not only brighten the space but also heighten the connection to the landscape outside.

A significant aspect of this architectural design is its commitment to sustainability. The building incorporates an innovative approach to energy management, integrating systems for solar energy collection and rainwater harvesting. This minimizes the ecological impact of the structure while promoting local resource use.

The Folded-Roof Turfhouse distinguishes itself from similar projects through its seamless integration of form and function, meticulous attention to material choice, and commitment to sustainability. Its architectural design addresses both aesthetic and practical concerns, making it a relevant example for future architectural endeavors in similar climates.

For those interested in a deeper understanding of the project, examining the architectural plans, sections, and detailed designs can provide insight into the thoughtful design ideas that define this architectural endeavor. Explore the unique features and functional layouts that make this project a reliable model in environmentally responsive architecture.
