Natural Wood Accents and Lattice Shading Define a Sustainable Living Space

Project in-detail

Utilizing prefabricated concrete walls and innovative lattice shading, the design creates a harmonious indoor-outdoor connection, offering a sustainable living environment tailored for modern family dynamics.
5 key facts about this project
01
Utilizes prefabricated concrete walls for rapid construction and reduced waste.
02
Incorporates customizable lattice shading to optimize natural light and ventilation.
03
Features a green roof system designed for biodiversity and stormwater management.
04
Employs recycled materials throughout to enhance sustainability.
05
Creates flexible interior spaces that can adapt to changing family needs.

### Overview
Located in a region characterized by a hot, arid climate, the project centers on the creation of a sustainable and adaptive living environment. The design is informed by principles of bioclimatic architecture, aiming to develop a structure that reacts dynamically to climatic conditions and user needs. The intent is to serve as a reference point for future residential developments, balancing functionality with environmental stewardship.

### Spatial Strategy
The design features a clear volumetric progression, employing grid frameworks and varying mass to create double-height spaces that enhance spatial flow. Distinct zones within the home include bedrooms (35%), social areas (30%), service zones (21%), and circulation spaces (14%), allowing for both privacy and communal interaction. A modular approach enables adaptability, permitting rooms to serve multiple functions and enhancing everyday usability.

### Materiality and Sustainability
Construction materials prioritize sustainability and efficiency. Prefabricated concrete walls accelerate assembly and minimize waste, while alveolar concrete slabs provide thermal mass and acoustic insulation. The incorporation of recycled materials into lattice systems reflects a commitment to eco-friendly practices. Features such as sliding glass windows facilitate natural light and ventilation, complemented by customizable lattice shading modules that regulate sunlight and maintain indoor comfort. The integration of solar panels and water recycling systems contributes to energy efficiency and self-sufficiency in water usage. Effective cross-ventilation strategies further reduce dependence on mechanical cooling, supporting a holistic approach to sustainable living.

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.
