Equipped with a rainwater harvesting system and constructed using an Xlam framework, these modular living spaces provide an environmentally sensitive solution adaptable to diverse climatic conditions.
5 key facts about this project
01
Modular units designed for easy rearrangement to fit site-specific conditions.
02
Integrated rainwater harvesting system enhances sustainability and self-sufficiency.
03
Constructed with an efficient Xlam framework for improved structural integrity.
04
Facades clad in wooden slats contribute to thermal performance and aesthetic appeal.
05
Solar greenhouse promotes biodiversity and provides natural cooling for living spaces.

IMPLUVIUM WOODEN offers a modular housing solution designed for both Mediterranean and Alpine climates. The project focuses on flexibility and sustainability, featuring nine distinct modular units. These units adapt to various living needs and promote a practical approach to construction and habitation. The design seeks to create comfortable living spaces through careful planning and environmental consideration.

Modularity and Efficiency

The design features nine modular units, most of which are dimensioned at 3x4x3.3 meters. This uniform size allows for various arrangements, accommodating the unique preferences of residents. The construction process is methodical, including important stages such as excavation, tank insertion, and the positioning of a concrete slab foundation. These steps ensure a smooth building experience and expedite the transition to livable spaces.

Sustainable Design Features

Sustainability is a key aspect of the design. Each housing unit incorporates photovoltaic panels, generating energy to reduce reliance on external methods. Additionally, there is a solar greenhouse that supports natural cooling and enhances local biodiversity. The rainwater harvesting system comprises components such as impluviums and UV filters, emphasizing the overall commitment to efficient water management.

Material and Construction Details

Construction relies on a lightweight Xlam framework that provides strength and durability. The facade is clad with wooden slats, which adds visual appeal and improves thermal performance. Various insulation types contribute to maintaining a comfortable indoor environment. A breathable exterior plaster is applied to enhance resilience against changing weather conditions, ensuring longevity.

Final Design Detail

The arrangement of the modular units allows for the creation of community spaces that foster interaction among residents. By designing neighborhoods that blend individual living areas with shared environments, the proposal encourages a sense of belonging while respecting personal privacy. Ultimately, the design reflects a modern approach to housing that considers both individual and communal needs.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
