Private project design and production
Building a mobile sauna from mainly reused or biodegradable materials.
An exploration into sustainable, adaptable design, this project centers on the creation of a mobile sauna built on a reclaimed bike trailer, using primarily reused and biodegradable materials.
The sauna’s structure is crafted from construction timber, reclaimed wood, and recycled metal, providing strength while reducing reliance on new materials. The walls incorporate reused polycarbonate panels and car insulation, with additional insulation provided by repurposed yoga mats. In its own small-scale way, the sauna emphasizes a commitment to sustainable material choices over conventional, resource-intensive options.
Constructed on a bike trailer, the sauna can be easily transported to various locations, inviting users to experience the beauty of the temporary while preserving the integrity of these environments.
As a building project, much learning has come from the process—not only through repeated reminders that materials have a life of their own beyond 3D models but also through the importance of proper facilities and tools for effective construction.
SIZE: 4 m2
LOCATION: Basel, Switzerland
TIME: 8 weekends (spanning over a year) Worked on the project with a fellow architect.

A modest cloth sheet at the entrance creates a small changing area, lending a sense of ritual to the experience.




With semi-translucent polycarbonate walls, the sauna offers glimpses of movement within—suggesting activity but preserving a sense of privacy. From inside, users can look out, letting the colors and light of the surroundings filter softly through the walls, connecting the interior to its setting.
Inside, the compact layout provides seating for up to four, inviting a close, shared atmosphere.

Lists are used to secure the polycarbonate and cover areas where the raw use of handheld tools is most evident.

The sauna’s walls, crafted from reused polycarbonate, are secured with metal plates that hold the panels in place without penetrating the material, exemplifying a thoughtful design for disassembly.
The entrance features a simple door that rotates around a wooden rod. Upon entering, visitors are asked to bow down, creating a sense of entering a sacred space and emphasizing the transition from exterior to interior.
Master thesis Sustainable Architecture
Transforming an old farm into a sustainable settlement through a circular mindset.
A critical remark regarding the current take-make-waste culture prevailing in both the Danish building industry, as well as in the Danish lifestyle, concerning a transformation of an old farm located at a site central in the city Rebild, Denmark.
Selective demolition has been proposed by the municipality, which this thesis aims to challenge by introducing the advantages and possibilities of transforming the existing buildings into new functions, maintaining the history and integrity of the site.
The thesis proposes to develop new dwellings on the empty plot next to the existing farm, taking offset in the continued demand for housing in the municipality. The design of these new dwellings aims to push the current Danish building culture of larger and larger homes, by proposing that we can get more out of less with better-planned space and more shared facilities, which is inturn introduced in some of the existing buildings on site.
With a tectonic approach to the design, the thesis revolves around lowering the embodied energy in the new buildings, working mainly with biodegradable materials and reusing materials available from the site, sustaining a comfortable indoor climate while also proposing greener alternatives to some of the daily routines of a Dane.

Due to an efficient building envelope, the new buildings have a total energy frame of 37,4 kWh / m2 / year and they, therefore, comply with the Energy frame BR18 of 38,3 kWh / m2 / year. If solar panels are added, the dwellings can reach the low energy frame of 27 kWh / m2 / year.
Since the reusable material from the site, was not enough to make up all new buildings, new materials were instead analysed, to find the most sustainable solutions. Here it was also taken into consideration, that the different procedures for reusing materials on site would result in different global warming potentials - as seen with the reused metal sheets which would be significantly more sustainable if reused directly.

Design project, 8th semester. AEC global teamwork project
Aim: To be resilient against hurricanes and earthquakes, self-sustaining with water and electricity and Eco-friendly using local materials such as bamboo and terrazzo.
This project is focused on providing a modern and resilient engineering faculty for the students of Puerto Rico.
This was an AEC Global Teamwork collaboration organized by Renate Frucher, lecturer at Stanford University. It involved structural engineers from China and Colombia, construction managers from Denmark and Turkey and an MEP engineer from Switzerland.
The innovative project aims to educate the next generation workforce by engaging with multiple disciplines internationally through Project-Based Learning (PBL) activities.
The course objectives include developing, implementing, testing, and assessing:
1) innovative learning and collaboration technologies such as Meet-in-VR and Prospect.
2) knowledge capture, sharing and use technologies, such as BIM360, Dynamo, Insight and other Revit plug-ins
3) complex processes involved in international collaboration work

Large Classroom - Mobile furniture allows flexible layouts, with classrooms opening to exterior tribunes for an amphitheater-like stage. Rooms can also be cleared and repurposed, such as for testing during a pandemic.

Throughout the faculty, diverse study spaces are offered, with terrazzo zoning in the naturally ventilated areas. This design ensures effective functionality during a pandemic by supporting airflow and adaptable seating for social distancing.

Junior architect Sustainability consulting
Aim: To understand the processes of working in a bigger design studio, handeling different projects at various stages, always focusing on sustainability and building performance optimization.
As a Sustainability Consultant at Herzog & de Meuron, I developed workflows and strategies to optimize internal analysis and simulation processes, performed Life Cycle Assessments (LCA), conducted daylight and solar studies, analyzed thermal and visual comfort, and carried out wind studies. I also provided sustainability and performance consulting, formulated sustainability strategies for competition and early design phase projects, and supported team members in effectively using software tools for project work.
Additionally, I contributed to the firm’s knowledge base by documenting and sharing sustainability insights, as well as developing analytics processes. I enhanced the functionality of the Rhino toolbar, streamlining design processes for the team.
Finally, I conducted a research project on the carbon emissions of eight finalized projects, reverse engineering them to estimate embodied carbon during early design phases. All of which was showed cased to the rest of the office during the annual summerparty.

Integrated Design of Sustainable Tectonic Architecture
Off-grid cabin in the woods working with passive and active solutions, genius loci and the human sense of vision, touch, and movement.
Located in Vodskov, Denmark, nearby one of the lakes, tugged in between two pathways and into the slope of the hill, one finds this small cabin. The cabin functions as a writer’s retreat, where the writer can pull away from the noise of everyday life and focus of the nature with an undisturbed view of the forest through the window over the desk. A smaller excavation of the hill makes space for two concrete walls to lay the backbone of the cabin, while the main body is constructed in wood.
This main body is a furniture, where the occupant is offered different niches to retreat and occupy for whatever purpose they see fit. In that way the retreat relates both practically and poetically to the place it is situated, responding to the genius loci, and addressing the human sense of vision, touch, and movement.
With passive and active solutions and off-grid strategies the cabin can keep a low energy consumption while providing the visitors with a soothing indoor environment. Different DGNB requirements have been obtained, such as visual comfort, users’ possibility to control indoor environment and the use of drinking water and management of wastewater.
