ETFE-Focused Urban Living Solution Integrating Modular Units and Efficient Use of Space

Project in-detail

Incorporating transparent ETFE materials and a compact technical box, this urban living solution redefines efficiency and adaptability in a minimal footprint designed for two occupants.
5 key facts about this project
01
Constructed using ETFE for enhanced lightness and transparency.
02
Incorporates a technical box that centralizes utilities for space optimization.
03
Features a modular design allowing for flexible interior configurations.
04
Utilizes repurposed shipping containers to promote sustainability.
05
Integrates a pocket bathroom concept to maximize living efficiency.

**Overview**
Located in a densely populated urban setting, the project addresses the challenges of compact living while fostering a dynamic social environment. With a minimal footprint of approximately 25 square meters, the design caters to the needs of two individuals, aiming to provide an effective solution to off-grid living. The approach reflects the critical issues present in rapidly urbanizing areas, where both space limitations and cultural deficiencies are prevalent.

**Adaptability and Spatial Optimization**
The design philosophy centers on adaptability, allowing the living space to evolve with its occupants. The structure, intended to maximize utility, is designed to integrate into existing urban voids, fostering a relationship between new and established buildings. This adaptability is further exemplified through features like the technical box, which consolidates plumbing and electrical systems, and the "Swiss pocket-knife bathroom," a compact solution that offers multifunctionality within limited square footage. Such configurations promote personalization, enabling various arrangements for living and sleeping areas while ensuring access to natural light.

**Material Selection and Sustainability**
The project employs a carefully curated selection of materials that enhance both functionality and aesthetics. ETFE, known for its flexibility and light permeability, is utilized to optimize natural light while minimizing thermal mass. Complementary materials, such as insulated Kingspan panels and lightweight hollow core concrete, contribute to energy efficiency and structural integrity. Floor finishes include terrazzo, providing durability alongside visual appeal, while repurposed shipping containers serve as a sustainable building option. The design’s emphasis on these materials supports an environmentally conscious approach to urban residential design.

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.
