Terraced greenhouse sectors create a unique microclimate system while seamlessly incorporating a restaurant that emphasizes sustainable practices and efficient resource management.
5 key facts about this project
01
Terraced design optimizes views of Hverfjall volcano.
02
Four distinct climate zones support diverse plant species.
03
Off-the-grid systems ensure complete self-sufficiency.
04
Biogas plant converts waste into usable energy.
05
Water treatment system utilizes plants for gray sewage recycling.

The Green Cascade project is located near Hverfjall volcano in Iceland. It combines a restaurant with a greenhouse, focusing on preserving the beautiful views of the surrounding landscape. The design concept emphasizes the relationship between the built environment and nature while promoting sustainability and enhancing the user experience.

Terraced Greenhouse Design

The layout of the project features multiple terraces that adapt to the site's slope. This design allows the greenery to flow downwards visually, connecting the building to the landscape. Each level creates opportunities for people to engage with nature. Different greenhouse sections encourage various kinds of plant growth, adding to the overall aesthetic appeal.

Climate Zone Integration

Inside the greenhouse, there are four specific climate zones, each designed for different types of plants. These include a temperate area, a tropical zone for bananas and dates, a nursery for young plants, and a section for Mediterranean climate plants. This division not only supports a diverse array of agriculture but also provides educational experiences for visitors about different ecosystems.

Sustainability Practices

Sustainability is a key focus of the project. It follows an off-the-grid model, aiming for complete self-sufficiency. A biogas plant processes organic waste into energy, while a compost heap converts biodegradable materials into fertilizer. Additionally, a water treatment system cleans gray sewage by using plant systems, ensuring that water is reused and contributing to the project's environmental goals.

Thermal Efficiency and Functionality

Thermal efficiency is carefully considered in the building's design. The arrangement of spaces minimizes heat loss, placing the warmest areas away from cold exposure. Public and private spaces are clearly defined. Public areas center around the greenhouses, while support zones like the kitchen and nursery are less visible. This layout improves the flow of operations and enhances the overall visitor experience.

Visitors can enjoy the dynamic interaction between the restaurant and the lush, vegetated terraces. The design encourages guests to appreciate the natural surroundings and engage with the lush greenery while enjoying their meals.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
