JOANNA DAY, NICHOLAS LANGSTAFF
Rammed Earth Wellness Retreat Integrating Natural Water Elements

Project in-detail

Constructed from rammed earth and situated adjacent to a natural pond, the Eco-Spa provides a sustainable retreat focused on wellness and environmental sensitivity.
5 key facts about this project
01
Constructed to minimize carbon footprint, the Eco-Spa uses locally sourced rammed earth for its walls.
02
The design incorporates floating reed beds to enhance the pond's water quality and promote biodiversity.
03
High-level clerestory windows provide ample natural light while facilitating cross ventilation.
04
A hydrothermal heat pump system delivers efficient heating and cooling through renewable energy sources.
05
The living roof serves as a green insulation layer, aiding rainwater management and supporting local flora.

The Elemental Eco-Spa offers a refined approach to architecture by combining luxury with sustainability in the Latvian landscape. The design promotes wellness and relaxation while being carefully integrated into the natural terrain. It aims to create a zero carbon retreat that enhances the environment instead of disrupting it.

Architecture Concept
The design seeks harmony with the existing landform, allowing the Eco-Spa to rise naturally from its setting. This connection to nature is underscored by its orientation, which guides visitors towards a central pond that serves as both a beautiful focal point and an essential resource for the resort. By preserving existing trees and the contours of the land, the architecture fosters a sense of place.

Materials and Sustainability
Rammed earth is the main building material, chosen for its ability to store heat and control humidity. The walls exhibit colors made from local clay, providing an aesthetic that reflects the region’s geology. This choice of materials supports sustainable practices by reducing transportation needs, highlighting the commitment to environmental responsibility.

Water Management and Functionality
A central feature of the Eco-Spa’s design is its water management system. It uses an open loop hydrothermal water source heat pump combined with a fired clay filtration process. The system operates with energy from photovoltaic panels, effectively meeting the hot water demands of the resort while maintaining a low carbon footprint. The pond is enhanced by floating reed beds, contributing to water purification and promoting biodiversity within the ecosystem.

Natural Ventilation and Light
The interior spaces are designed to utilize natural light and airflow. High-level clerestory windows and south-facing glazed facades allow ample sunlight, while also enabling cross ventilation. These design choices create comfort throughout the year and establish a calm environment. The thoughtful use of light and air supports the Eco-Spa’s focus on wellness, inviting guests to engage with the landscape.

The presence of rammed earth walls alongside views of the pond creates warm spaces. These areas encourage relaxation and contemplation, reflecting the integration of architecture and nature.

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.
