Corten Steel and Prefabricated Concrete Harmonizing with Native Landscape

Project in-detail

Constructed with Corten steel and prefabricated concrete, the design integrates rainwater management and preserves native vegetation to create adaptable residential spaces in a harmonious relationship with the landscape.
5 key facts about this project
01
Constructed using prefabricated concrete to minimize energy waste.
02
Incorporates a rainwater collection system for self-sufficient water use.
03
Features a "U" shaped floor plan to enhance indoor-outdoor connectivity.
04
Prioritizes native vegetation, preserving the local ecosystem.
05
Includes separate modules for public and private living spaces.

"Bucolic Housing" is an exploration of sustainable modular living in the landscape of Évora, Portugal. The design works to connect with nature while providing a functional residential solution. The focus is on a modular layout that adapts to different lifestyles, emphasizing simplicity and environmental responsibility.

Design Concept

The layout consists of a "U" shaped floor plan that creates a flow between indoor and outdoor spaces. It has three main modules that guide movement from public to private areas. The entrance module includes the living room, a small service bathroom, and storage space. Next, the kitchen and dining area are designed for shared meals and gatherings. The private area consists of bedrooms, each with its own bathroom, allowing for privacy.

Sustainability Initiatives

Sustainability is at the heart of the design. The project carefully preserves the existing native plants, which helps maintain local ecosystems and avoids using non-native species. The design also ensures that soil permeability is kept intact, which contributes to ecological balance. This thoughtful approach reflects an awareness of how the built environment interacts with nature.

Material Usage

Material choices play an important role in the design's sustainability goals. Prefabricated concrete is the main structural material, chosen for its efficiency and reduced energy use during construction. This decision helps lower the overall environmental impact. Corten steel is used to provide durability and aesthetic appeal, weathering naturally over time. Glass is incorporated to enhance natural light and strengthen the connection between inside and outside.

Rainwater Management

An effective rainwater collection system is another key feature. It captures rain from the roof and directs it to a filtration and storage setup. This allows for the use of treated water within the plumbing system, reducing reliance on other water sources. By integrating this system, the design promotes responsible water use and underlines the principles of sustainable living.

The design includes careful attention to solar orientation, which optimizes natural light and reduces energy consumption. This method creates a living space that respects its surroundings while providing comfort and function for its inhabitants.

`
Competition organisers

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.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
