The OrCS Tower is a remarkable structure located in the unique geological environment of Grjótagjá Cave in Iceland. It is positioned over the Continental Shelf and is intended to offer visitors expansive views of the surrounding landscape, including Lake Mývatn and Hverfjall volcano. The design concept takes cues from the local volcanic forms, creating a structure that reflects the natural features of the area while also serving as a point of interest for visitors.

SUSTAINABLE DESIGN

Sustainability is a core element of the OrCS Tower. A rainwater catchment system has been integrated into the design, providing a reliable source of potable water. This helps to minimize the environmental impact of the building. The project also makes use of geothermal energy for electricity and heating. This choice aligns with current practices in sustainable architecture, aiming to reduce reliance on nonrenewable resources.

ACCESSIBILITY

Accessibility is an important aspect of the tower’s design. A vertical platform lift allows all visitors, including those with disabilities, to reach the viewing deck. This feature highlights a growing awareness in design that prioritizes equal access for everyone, ensuring that the structure can be enjoyed by a wide range of users.

FUNCTIONAL SPACES

In the layout of the tower, public and private areas are clearly defined. Bathing facilities are reserved for guests, creating a more private experience. Public areas are open to all, allowing visitors to engage fully with the space. This thoughtful organization enhances the overall utility of the building and ensures that it meets the diverse needs of its users.

The distinctive outline of the OrCS Tower is complemented by its connection to the landscape. The loop bridge not only links the two continental shelves but also serves as a means for exploration. It invites visitors to observe the surrounding natural beauty and geological features, fostering a sense of connection to the land.
