Folded Roof Structure Enveloped in Green Roofing with Sustainable Wooden Materials Functioning as a Community Coffee Shop

Project in-detail

Nestled beneath a folded roof that harmonizes with the volcanic landscape, the sustainable coffee shop incorporates a green roofing system and locally sourced wooden materials to create a welcoming space for community engagement.
5 key facts about this project
01
The folded roof design mimics the natural contours of the surrounding volcanic landscape.
02
A green roofing system integrates local vegetation for enhanced insulation and environmental benefits.
03
Sustainable materials include charred wooden shingles, which provide durability and weather resistance.
04
The coffee shop features high-performance low-E double glazing to optimize energy efficiency.
05
Movable partition walls allow for flexible space usage, accommodating various community events and gatherings.
The Folded-Roof TURFHOUSE is an architectural project designed to function as a coffee shop, carefully situated in the scenic landscape near Hverfjall, a volcano within the Mývatn region of Iceland. This project embodies a thoughtful integration of contemporary architecture with traditional design principles, drawing inspiration from Iceland's historic turf houses. Through its innovative form and sustainable practices, the TURFHOUSE represents a blend of cultural heritage and modern functionality.

This architectural design serves not only as a gathering space for visitors to enjoy coffee but also as a venue for community interaction and cultural exchange. The central idea revolves around creating a space that is both welcoming and reflective of its surroundings, engaging with the natural landscape while delivering an efficient and inviting atmosphere. The primary visual element of the building is its folded roof, which mirrors the undulating forms of the local terrain and volcanic features. This unique roof design reduces wind resistance, an essential consideration given the often harsh weather conditions of Iceland, while also allowing for rainwater collection that contributes to the building’s sustainability.

The project incorporates several essential materials that enhance its structural integrity and environmental performance. Concrete is employed for the main framework, providing durability, while laminated veneer lumber (LVL) is used for the roof beams, allowing for a lightweight yet strong construction. The green roof system not only promotes insulation but also enriches the visual aesthetics with naturally occurring vegetation. The building is equipped with low-E double-glazing windows, optimizing energy efficiency by regulating heat and light, and solar panels are integrated into the roof, making the coffee shop self-sufficient in energy use.

Spatially, the interior layout features a central hall designed to serve as the core of the coffee shop, offering a flexible environment that accommodates various functions. The high ceilings and strategically placed skylights ensure abundant natural light, creating an uplifting atmosphere conducive to social interactions and relaxation. Additionally, movable partition walls are provided to allow for adaptability in space usage, supporting diverse community events and gatherings.

One of the standout aspects of the Folded-Roof TURFHOUSE is its deliberate engagement with the local environment and climate. The green roof features not only serve practical insulation purposes but also foster biodiversity by providing a habitat for local flora and fauna. The design reinforces a sense of place and identity, respecting the historical context of traditional building techniques while presenting a contemporary perspective on architecture coupled with ecological considerations.

The project highlights significant design approaches that resonate with the shifting narratives of modern architecture, particularly in a region like Mývatn, defined by its natural beauty and unique geological features. By incorporating traditional Icelandic concepts while embracing innovative building technology, the TURFHOUSE stands as a notable example of how architecture can enhance communal experiences and foster relationships with nature.

In exploring the architectural plans, sections, and overall design ideas of the Folded-Roof TURFHOUSE, one can gain deeper insights into the careful thought that has gone into this project. The nuanced interplay between resilience, sustainability, and cultural significance is evident throughout, making this coffee shop a meaningful addition to its environment. For anyone interested in the intersection of contemporary architecture and historical practices, an exploration of this project presentation will offer a wealth of details and a clearer understanding of its architectural merits.
