Augustine's Garden is a residential ensemble resulting of a transformation of former low-rise industrial buildings in the courtyard of a 1900s quarter. The site is converted into a contemporary urban garden, and the post-industrial aesthetic of the buildings reflects the concept of adaptive reuse.






















The residential project of 38 dwellings combines sustainability, functionality, and a social character. It uses local materials such as compressed earth blocks and timber, reducing the carbon footprint. The spaces are flexible, well-ventilated, and promote community living and energy efficiency.













At Beaucastel, water, wind, soil, and sun shape an architecture rooted in place, using excavation earth for cellars and walls and a rain-fed cistern that supports winemaking and cools interiors passively. Lime, clay, earth, sand, wood, stone ensure an aging well and self-sufficiency project.











































How to tackle the typical Flemish “Fermette?” After a critical analysis, the answer was found in densifying and reconnecting with the surroundings. Doing so by transforming a part of the roof into a wintergarden and optimizing the existing spaces.






























A very small house, built without cement or adhesives. Foundations are solid granite blocks. Prefabricated timber walls filled with hempcrete, which insulates and wraps the building, plastered with lime. This "neo-timber-frame" method minimizes thermal bridges and uses natural, sustainable materials












The interior was made with reclaimed materials: terrazzo from discarded grave monuments, walls from an Audi pavilion and panels made from wool of Rotterdam sheep. The materials are not used "as found"; we've tried to design new aesthetics with respect, love and dedication.

















Our Tiny Office is a functional but compact, serene workspace built from mainly wood, hempcrete and rammed earth. Natural materials and minimal tech reflect our vision for sustainable design proving that eco-conscious building enhances comfort and atmosphere, and does not limit it.









Bademaschinen lies in the Oslo Fjord and is inspired by the Sjøbadehus with their traditional roof shapes and towers. The primary design driving factor was the reuse of teak window frames from a 1960s nursing home outside of Oslo that was undergoing rehabilitation and conversion into housing.
The Re:House renovates and extends an existing house ensemble; all construction measures were implemented with aim to minimize the ecological footprint; 60-65% ReUse building materials were used within a radius of 15 km; local harvested materials etc.










The Beesculpture is a space for Bees and Humans. The exterior design shows the negative form of a bee cell and reflects the basic hexagonal structure of bees. The 7 meter high space was built with sustainable materials in a collaborative effort with many volunteers. A space for contemplation.







Kiosk zur FÜRstin is a collaborative project together with Studio Stadt Region from Munich. The kiosk consists of 90% reused building material that were obtained directly from the surrounding mayor construction site – its offcuts, its demolition waste or the trees that had to make way. We built without using any cement or fresh concrete.

Here are the top three projects chosen by our community.
Rear garden extension and refurbishment of a Victorian terrace in East London. The design introduces large sliding doors, pivot door, and roof-lights for daylight, with bespoke timber joinery, exposed structural timbers, and cork flooring. Focus on sustainable materials and cost-effective detailing.














The Blue House is a sustainable retreat in the Azores, built with wooden prefabricated elements and clad in up-cycled ocean plastic, and local carpentry techniques. Blending modern design with local stone and native plants, it exemplifies low-impact architecture in harmony with its coastal setting.

















Through the renovation, a landscape architecture firm expands its office. A black steel staircase sculpture connects all levels and recalls the barn’s original use. Natural materials like clay, wood, and concrete link old and new, creating a timeless architectural intervention.
