Vertical Green Systems and Cellular Concrete in Compact Urban Living

Project in-detail

Incorporating vertical green systems alongside cellular concrete, the design integrates sustainable elements and adaptable modular spaces to create a compact home tailored for urban living.
5 key facts about this project
01
Modular design allows for flexible expansion and reconfiguration.
02
Vertical green systems enhance biodiversity and urban integration.
03
Cellular concrete promotes effective thermal insulation and lightweight construction.
04
Self-supporting platform elevates the structure, improving aesthetics.
05
Bioclimatic orientation optimizes natural light and energy efficiency.

The Microhome is designed to meet the growing need for compact and adaptable living spaces in urban areas. With a focus on both public and private functions, the design merges innovative modular construction with an emphasis on sustainability. The aim is to create efficient homes that can easily adjust to the needs of families while promoting environmental consciousness and energy efficiency.

Modular Construction

The project utilizes a base construction module measuring 50x50 cm. This allows for flexible configurations, catering to the varying needs of residents. This modular approach optimizes space and enables multiple units to be combined in different orientations based on individual preferences. The layout ensures a clear separation between public and private areas, enhancing functionality.

Structural Design

A bolted metal framework supports the Microhome, resting on a self-supporting platform. This structure provides stability while maintaining a lightweight appearance. The elevated design enhances visual appeal and offers the possibility of dismantling if necessary. The external walls are made from cellular concrete blocks, which allow for easy installation and provide effective thermal insulation, improving energy performance.

Bioclimatic Orientation

The layout is intentionally oriented to capture natural light and optimize thermal conditions. The living area benefits from sunlight, which increases energy efficiency and comfort. Additionally, micro-perforated sliding panels offer shade during warmer months, creating a balanced indoor climate without excessive reliance on artificial heating or cooling. The presence of photovoltaic panels on the roof highlights a commitment to renewable energy within the design.

Green Integration

A notable feature of the Microhome is the vertical green system, which serves as a private garden space within the urban setting. This vertical garden not only adds to the visual appeal of the home but also supports local biodiversity and enhances the ecological value of the area. This design element aims to create a better connection between the built environment and nature.

The Microhome combines many thoughtful design elements that offer practical solutions for contemporary living. Its adaptable nature and integration of green principles aim to address modern housing challenges. The vibrant vertical garden introduces life and greenery against the minimalist backdrop, showcasing a balance between nature and architecture.

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.
