Mobile Eave Structure with Cross-Laminated Timber and Microcement Finish

Project in-detail

A mobile eave system enhances solar access and rainwater collection in a low-cost prism structure, constructed with cross-laminated timber and microcement, providing efficient residential space.
5 key facts about this project
01
Mobile eave system adjusts to seasonal sunlight and weather.
02
Integrated rainwater collection system optimized for efficiency.
03
Cross-laminated timber structure enhances structural strength and sustainability.
04
Unique bent A-frame design maximizes interior space and natural light.
05
Microcement finish provides durability and a modern aesthetic.

The project showcases a thoughtful approach to sustainable design, embedded in an urban environment that balances ecological care with social value. The focus is on a low-cost prism structure that efficiently serves its function while aiming to reduce environmental impact. The overall concept blends economic factors, ecological responsibility, and social engagement, creating a coherent response to modern architectural needs.

Sustainable Design Concept

The design begins with a basic rectangular prism, modified to enhance the use of solar energy and the collection of rainwater. Lowering one vertex creates a sloped surface that maximizes sunlight exposure and facilitates water harvesting. This clever solution enhances both the building’s functionality and its appearance, allowing for seasonal adjustments in light and climate management.

Ventilation Strategy

The project emphasizes an effective ventilation strategy that promotes natural airflow. Openings are thoughtfully placed at various heights, enabling cross ventilation throughout the interior. This design choice improves indoor air quality and comfort while reducing the need for mechanical cooling. The approach aligns with sustainable design principles by fostering a healthier living environment.

Material Selection

Materials have been chosen with care, ensuring both performance and environmental responsibility. The use of aluminium roofing sheets, cross laminated timber, and rigid thermal insulation are notable choices that reflect a focus on durability and energy efficiency. The Exterior Insulation Finish System contributes to the building's overall energy conservation, while microcement flooring, reinforced concrete, and extruded polystyrene foam enhance thermal performance and longevity.

Design Outcomes

The careful selection of design elements leads to a building that meets practical needs while engaging with its environment. The result is a structure that blends well with its surroundings and speaks to its purpose. The mobile eave serves as an effective shading system and protection against rain, adapting to varying weather conditions and enriching the user experience through its responsiveness.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
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.
