The project at Liepaja beach in Latvia features a hut designed to provide shelter while encouraging connection to the coastal surroundings. Its design concept focuses on simplicity and functionality, ensuring that the space serves both practical needs and aesthetic appreciation. The hut is situated to take advantage of its location, referencing local architectural traditions while creating an inviting environment for those who use it.

Form and Spatial Configuration

The design includes a single internal space that is mirrored in the external shape, characterized by a steeply pitched roof. This form respects the traditional Latvian houses, creating a familiar silhouette that blends with the landscape. The barrel-vaulted walls are intentionally positioned at eye level, allowing for wide views of the sea and sky. This strategic arrangement invites occupants to immerse themselves in the natural beauty surrounding them.

Material Choices

The exterior of the hut is wrapped in marine-grade plywood, selected for its ability to withstand the harsh coastal climate. This plywood is complemented by curved battens that provide additional support and visual interest. Inside, locally sourced larch hardwood forms the load-bearing elements, such as columns, beams, and joists. This choice adds both strength and warmth, contrasting with the umber tones of the exterior. The flooring, made from naturally finished silvered birch wood, connects the interior space to the local ecosystem.

Functional Design Elements

Accommodating four adults, the hut offers a well-thought-out layout. Two sleeping areas are located in a raised mezzanine, while another area on the lower level provides additional space. The design incorporates removable beds into the storage solutions, allowing for flexible use of the area. A wood-burning fire serves as the main heat source and cooking facility, reflecting a commitment to sustainability through the use of locally sourced fuel.

Essential hygiene facilities are located in a separate outbuilding, which includes a compost toilet and a gravity-fed shower. These designs help reduce the environmental impact while ensuring that all necessary functions are conveniently addressed.

The exterior features ample openings that enhance natural light and air circulation. A high window allows for clear views of the sky, creating a sense of openness that promotes relaxation and contemplation. This attention to both form and function allows the hut to coexist comfortably with the coastal landscape while serving the needs of its occupants.
