Rammed Earth Facade With Geothermal Heating in a Sustainable Residential Design

Project in-detail

Combining a rammed earth facade with geothermal heating systems, this residential design prioritizes sustainability and energy efficiency while seamlessly integrating into its natural surroundings.
5 key facts about this project
01
Rammed earth construction enhances thermal performance and durability.
02
Geothermal heating reduces energy consumption for temperature regulation.
03
Sustainable materials include locally sourced elements to minimize transport impacts.
04
A green roof design promotes biodiversity and thermal insulation.
05
Cross-ventilation strategies optimize natural airflow throughout the living spaces.
The Apothalassia House is an architectural design project that exemplifies a commitment to sustainability, energy efficiency, and an integration with the natural environment. Located in a scenic area that allows for expansive views, the project is designed to minimize energy consumption through various passive design strategies. The architecture serves residential functions while promoting ecological stewardship by utilizing materials and methods that align with this ethos.

The overall design features an organic silhouette that complements the landscape's natural contours. The building emphasizes cross-ventilation and maximizes natural light, creating an inviting atmosphere. Key materials include rammed earth for the facade, which provides thermal mass and durability while enhancing the aesthetic of the building. The choice of local materials not only supports sustainability but also fosters a deeper connection to the regional context.

Architectural Features and Unique Approaches

A notable aspect of the Apothalassia House is its innovative approach to sustainability. The project incorporates geothermal heating systems, efficient grey water recycling, and rainwater harvesting, contributing to an integrated framework of environmental responsibility. The design emphasizes passive systems to reduce reliance on mechanical heating and cooling, which positions the building as a model for energy-efficient residential architecture.

Another unique feature is the extensive use of rammed earth throughout the building, setting it apart from typical construction practices. This material selection contributes to low embodied energy and promotes thermal comfort. The integration of green roofs further aids in insulation and enhances biodiversity, establishing an ecological footprint that aligns with the surrounding environment.

Spatial Organization and Interior Design

The interior design of the Apothalassia House focuses on functionality and comfort while maintaining a cohesive aesthetic. Large windows throughout the living areas frame the external landscape, inviting natural light to permeate the space. The open layout facilitates easy movement and connection between different areas, enhancing daily living experiences.

Materials used within the interior such as gypsum plastering and plaster boards ensure a modern yet warm ambiance. Furniture selections complement the overall design philosophy, with an emphasis on natural materials and soft forms that resonate with the external environment.

The Apothalassia House serves as an important example of how architecture can prioritize sustainability without compromising aesthetic appeal or functionality. The effective integration of passive design strategies, innovative materials, and user-centric spaces demonstrates a comprehensive approach to residential architecture.

For further insights into the architectural plans, sections, and designs of the Apothalassia House, interested readers are encouraged to explore the project's detailed presentation. This examination will provide a deeper understanding of the architectural ideas and their implementation within this significant residential project.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
