Biophilic Design Enhanced by Photovoltaic Tiles and Hydroponic Integration in a Community Cafe

Project in-detail

Incorporating hydroponic systems and photovoltaic tiles, the design creates a sustainable community cafe that not only enhances air quality but also generates its own energy, fostering a vibrant public space for social interaction.
5 key facts about this project
01
Dynamic fluid forms mimic the movement of coffee.
02
Integrated hydroponic systems improve indoor air quality.
03
Photovoltaic tiles ensure on-site energy generation.
04
Perforated metal components allow for natural ventilation.
05
Charcoal filters enhance the efficiency of rainwater systems.

The Kremm Cafe serves as a modern coffee house that brings people together while respecting its environment. Located in an urban area, it focuses on creating a welcoming space for social interaction and community. The design draws inspiration from the coffee bean, which influences not just the space but also the experience of enjoying coffee. Fluid and organic forms are evident in the architecture, giving it a dynamic character that connects with the essence of what the café represents.

Energy Systems and Sustainability

Sustainability is an important aspect of the Kremm Cafe. The structure uses photovoltaic tiles on the roof to produce energy, allowing it to function with less reliance on outside sources. Micro turbines also support this energy strategy, making it more self-sufficient. To regulate temperature inside, tinted double-layered heat-absorbing glass, known as a Trombe wall, is utilized. This material allows sunlight to warm the space while keeping it cool during warmer months.

Architectural Form and Community Interaction

The layout of Kremm Cafe emphasizes fluidity, with open areas and sweeping lines that encourage movement and connection. Seating is arranged to promote social engagement, making it more than just a coffee shop – it serves as a place where the community can gather. The design mimics the experience of pouring coffee, creating an inviting atmosphere that resonates with visitors.

Environmental Integration and Biophilic Design

A key feature of the café is its incorporation of hydroponic systems, which add greenery and help improve indoor air quality. Plants such as English Ivy and Peace Lily are strategically placed to absorb carbon dioxide, contributing to a healthier indoor environment. Rainwater and greywater collection systems, equipped with charcoal filters, are also integrated into the design, reflecting a commitment to environmental responsibility.

Material Composition and Structural Elements

The café's structure features perforated metal components, which allow for practical integration of elements such as photovoltaic cells and micro turbines. This design not only enhances functionality but also creates interesting shadows and light patterns within the space. The strong choice of materials contributes to the whole experience, making the café a place that feels connected to the world outside.

A final detail in the design includes internal perforations that serve as CO₂ catchers. These features improve air quality while enriching the atmosphere inside the café. This attention to environmental impact shows a dedication to sustainability, providing a refreshing place for patrons to enjoy their coffee.

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.
