Curved Metal Walls and Compost Toilet in a Compact Living Space

Project in-detail

With its curved metal walls and a compost toilet system, this compact living space efficiently blends sustainability with functionality, creating an innovative retreat that prioritizes ecological sensitivity.
5 key facts about this project
01
Curved corrugated metal walls serve as both structure and compost silo.
02
A compost toilet system enhances environmental sustainability.
03
The living space features a raised pedestal bed with integrated storage.
04
Prefabrication techniques reduce on-site construction time.
05
Large glazing connects indoor areas with the surrounding landscape.

The site is surrounded by a peaceful landscape, highlighting a design that prioritizes balance between the built environment and nature. This structure is centered around creating a practical living space that enhances the experience of its users. A minimalistic approach allows for a better connection between indoor spaces and the outdoor setting, encouraging light and air to flow throughout.

Spatial Organization

The design consists of a main module that emphasizes simplicity and efficiency. This main area is divided into three distinct zones, each defined by thoughtfully arranged furniture that makes the best use of the available space. Upon entering, an inviting corridor introduces occupants to the surrounding views, establishing a direct relationship with the outside. This corridor serves practical purposes as well, functioning as a storage area and wardrobe space while directing movement within the accommodation.

Sustainability Focus

Environmental responsibility is a key feature of the design, evident in the arrangement of the wet area. A shower space is illuminated by a skylight, while the walls are made of curved corrugated metal. This metal serves a dual purpose; it acts as a physical boundary and functions as a compost silo for waste management. The inclusion of a compost separation toilet demonstrates a commitment to sustainability by efficiently managing waste and minimizing the impact on the environment.

Materiality and Construction

A careful selection of materials contributes to the overall character of the space. Wood, ceramic tiles, and curved corrugated metal are used to create a healthy indoor climate. The construction process emphasizes prefabrication, allowing the sleeping pod to be assembled off-site and delivered as pre-assembled segments. Ground screws provide stability for the structure, ensuring that the natural landscape remains intact during installation.

Interior Experience

In the sleeping area, large windows promote a strong connection to the surrounding environment, giving the space an airy feel. A balcony extends the living area, further integrating indoor and outdoor experiences. The bed is designed to be raised, resembling a pedestal, with built-in storage that reduces the need for extra furniture. This thoughtful design choice creates a calming atmosphere where functionality and comfort are prioritized. The arrangement fosters a sense of peace, making it an ideal space for reflection and rest.
