The Micro-dome-ship is located in West Cork, Republic of Ireland, and represents a modern approach to sustainable living. Designed for a couple, this compact home combines elements from different building methods while following a permaculture approach. The aim is to create a space that respects the environment and reduces waste.

Architectural Concept

The design makes effective use of the internal ground floor area of 24.28 m², creating a functional living space despite its small size. It includes separate zones for different activities: a mezzanine bedroom in a half-moon shape, a living area with a thermal mass bench for chilly evenings, and a kitchen that operates on gas sourced from a bio-digester. This careful organization of space ensures comfort while maximizing usability.

Material Usage

A significant focus of the project is its sustainable material choices, with 87% of the structure composed of natural and recycled components. The external walls feature earthbag construction, which serves to provide thermal mass and enhance energy efficiency. Cladding made from recycled copper, lime, and rock contributes to the building's longevity while aligning with environmental goals. Inside, the wall that hides the WC uses recycled bottles held together with lime mortar, reflecting a thoughtful approach to reducing waste.

Innovative Systems

The design includes a bio-digester tucked away in a utility closet. This device processes organic waste, turning it into compost and methane that can fuel the kitchen. This feature emphasizes the home’s self-sufficiency. The green cell terrace supports this system by managing grey water and carbon dioxide, resulting in an integrated design that focuses on sustainability.

Passive Design Elements

Effective temperature regulation is a key aspect of the Micro-dome-ship, thanks to its passive heating and cooling strategies. The ground floor is divided into two zones, with the green cell terrace acting as a heat pump. In winter, it captures warmth from the low sun, while in summer, it vents excess heat. This attention to climate considerations enhances the comfort of the living environment.

The project also incorporates bamboo as the primary wood material, demonstrating a commitment to sustainability by sourcing materials close to home. It is a choice that aligns with the overarching goal of creating an environmentally responsible living space.
