05
Enhances microclimate through shading and cooling.

The Vertical Spring project is an architectural initiative located in the city of Cologne. It aims to blend natural elements with the urban environment. The design encourages a connection with nature in a setting where green spaces are often limited. Instead of celebrating spring in parks and gardens outside the city, the project brings vibrant greenery directly into urban areas. The overall goal is to enhance biodiversity and improve the visual landscape through the integration of vertical gardens.

Facade Integration

The design incorporates a modular facade system that features green walls throughout the structure. These walls utilize hexagon planter boxes to support a variety of plant types, including both spring-blooming and evergreen species. With this arrangement, the project fosters a diverse visual experience while ensuring that the plants receive the necessary care through integrated irrigation and drainage systems. This design not only enhances the building's facade but also contributes positively to the surrounding environment.

Microclimate and Environmental Benefits

Vertical Spring is designed to improve the microclimate around the building. The green facade helps reduce heat gain by adding shade, which in turn creates a more comfortable internal environment for occupants. Expansive glass sections allow natural light to enter the building while being tempered by the greenery. This balance between glass and plants serves both aesthetic and environmental purposes, demonstrating that urban architecture can be both functional and pleasing to the eye.

Material Specifications

The structure is supported by lightweight metal hollow sections used within the planter boxes. This choice ensures that the planters are durable and can carry the weight of the plants while remaining manageable. The design also hides essential irrigation and drainage elements, promoting a clean visual appearance. The selection of materials is crucial for maintaining the health and sustainability of the vegetation over time, allowing the project to thrive as part of the urban landscape.

Incorporation of Nature

Vertical Spring moves beyond the boundaries of conventional urban development. Its design allows for adaptation to various building forms while placing a strong emphasis on ecological consideration. The result is a living environment that encourages interaction between people and nature. The project symbolizes a shift in how cities can grow—combining architecture with vibrant green spaces that enhance the quality of life. It reflects the potential for urban areas to include more greenery, making them not just places to live or work, but spaces that actively engage with nature.

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.
