沿着赫夫菲亚尔火山口步行，你会爬上一座已死火山的山坡。在史前的玄武岩石和黑土地景观中，你会感受到脚下的石头和不平坦的地面，风在荒凉的白色天空中呼啸，还有坡和山的动力。你会来到一个令人惊叹的北部景观，眺望米夫托湖，远处的特罗拉斯卡吉山脉和湖对面的温德贝尔格亚尔峰。然后你会沿着漫长的路程下山...

概念
我们的咖啡店灵感来自于岩屑锥形火山和冰岛环路的形式和体验。它是疲惫的徒步旅行者在登上火山口之前和之后的休息场所。圆形的形式受到了环形漫游的影响，而朝内的斜屋顶则向岩屑锥形火山口的内部结构致敬。

体验
咖啡店的中心是一个带有冰岛花园的开放式庭院。游客们在这个空间中循环，远处的火山口映入眼帘。建筑分为四个象限，每个象限提供独特的功能：咖啡店、洗手间、展览空间和有盖观景台。

游客从环形的开放式角落进入建筑。从接待区，他们可以向左移动使用洗手间和座位。或者，他们可以向右进入咖啡店，那里有一个优雅的咖啡吧和温暖的木色内饰。徒步旅行者可以在欣赏花园宁静景色的同时，放松身心，品尝热咖啡和小吃。穿过咖啡店，游客可以进入展览空间，通过低矮的画廊窗户，透过自然光线，了解到该地点地质的全面故事。最后，游客从画廊走出来，进入有盖的露台，可以欣赏到米夫托湖及其周围广阔的美景。

结构
该项目采用简单高效的模块化木框架结构。两根平行的大木梁形成了中心的十字形开口，朝内的胶合木椽子将正方形内框架与圆形外墙相连。大尺寸的门窗从咖啡店和展览中提供庭院景观。三个程序空间是相似尺寸的模块化组件，设计成易于在运输前进行预制，由卡车运到现场。建筑外立面采用烧黑的深灰色雪松木板，与现场的黑色玄武岩地面相呼应，而内部则采用温暖的裸露雪松木，与粗糙的石材家具和铜色金属亮点形成对比。

可持续性和运营
咖啡店位于偏远的国家公园中，可持续性是首要考虑。咖啡店采用地下地热泵提供电力和供暖，而凸起的混凝土地板采用辐射供暖。低辐射率三层玻璃减少了窗户和门窗的不必要热量损失，混凝土和木材外观具有较高的保温性能，隔绝了冰岛不可预测和恶劣的气候。朝内的斜屋顶可用于收集雨水，并将净化过的水存储并用于饮用、洗手和冲水。提供的厕所是干式堆肥，多余的堆肥可以用作花园肥料。用过的咖啡渣也提供额外的肥料，并有助于厕所堆肥。

咖啡店的设计可最少化员工，并可以在几乎不需要维护的情况下运行。我们建议咖啡店提供在较暖的国家生长的火山土壤咖啡豆，以补充赫夫菲亚尔火山口的徒步旅行。

Walking along Hverfjall Crater, you'll climb a slope to a long-dead volcano. In a prehistoric landscape of basalt rocks and black soil, you'll feel the rocks and uneven ground below your feet, the wind blasting across a barren white sky, and the momentum of slopes and hills. You'll arrive at a stunning northern vista, staring across Lake Myvatn, the mountains of Tröllaskagi beyond, and Vindbelgjarfjall across the lake. Then you make the long trek down...

CONCEPT
Our coffee shop is inspired by the form and experience of the tuff cone volcano and Iceland's ring road. It serves as a respite for weary hikers before and after their pilgrimage up to the crater's edge. The circular form is inspired by the circumambulation of the crater, while the inward-facing pitch roof pays homage to the tuff cone crater's interior structure.

EXPERIENCE
At the coffee shop's heart is an open courtyard with an Icelandic garden. Visitors circulate around this space that frames the volcano in the distance. The building is divided into four quadrants, each providing a unique function: coffee shop, restrooms, exhibition space, and a covered observation terrace.

Visitors enter the structure at an open corner of the ring. From the reception area, they can move left to use the restrooms and seating. Alternatively, they can move right and enter the coffee house, where they are greeted by an elegant coffee bar and a warm, wood-toned interior. Hikers can relax with hot coffee and light snacks while gazing out at the tranquil scenery of the garden. Moving through the coffee shop, visitors can then enter the exhibit space, which tells a comprehensive story of the site's geology while natural light streams in through low gallery windows. Finally, visitors exit the gallery onto the covered terrace, which frames expansive views of Lake Myvatn and its surroundings.

STRUCTURE
The project employs a simple and efficient modular wood frame structure. Two parallel mass timber beams form a cruciform opening at the center, and inward-facing glulam rafters bridge the square interior frame with the circular exterior wall. Large-format storefronts provide courtyard views from the coffee shop and exhibit. The three program spaces are modular components of similar dimensions, designed to be easily prefabricated before being transported to the site by truck. The building's exterior features a charred, dark gray cedar facade that relates to the black basalt grounds of the site, while the interior features warm, exposed cedar juxtaposed with rough stone furnishings and copper-toned metal highlights.

SUSTAINABILITY & OPERATIONS
The coffee shop is sited in a remote national park, sustainability is a priority. The coffee shop employs underground geothermal heat pumps for electric and heating needs, while radiant heating is used on the raised concrete floor. Low-E, triple-pane glass reduces unwanted heat loss through windows and storefronts, and the concrete-and-wood exterior presents a high R-value, insulating against Iceland's unpredictable and harsh climate. The inward-facing pitch roof allows for rainwater capture, and the purified water can be stored and used for drinking, handwashing, and flushing. The provided toilets are dry composted, and excess compost can be used as fertilizer for the garden. Used coffee grounds also provide additional fertilizer and assist with toilet composting.

The coffee shop is designed to be minimally staffed and can operate off-grid with little maintenance. We suggest the shop offer a variety of coffee beans grown on volcanic soil in warmer countries to complement the Hverfjall hike.
