Togthere with Nanine Carree, Miranda Reitsma I was asked to give feedback at the mid term review and the final presentation on June 11the of the design course featuring the N203 at the faculty of Built Environment of the Amsterdam Univesity of Applied Sciences.

The students developed impressive ideas vor future transit oriented development (TOD) along the N203 road and the train stations parallel to it by solving complex spatial puzzles with fresh ideas and the drive to improve quality of life.

The new head of urbanism at the Amsterdam University of the Arts, Academy of Architecture, Anna Gasco, asked Mathias to teach for the P1 design studio in 2024.

The assignment for this multidisciplinary design class will address the public space and buildings as ‘skin of the city’ in the areas around train stations.

Nature-inclusive construction was the central topic of the expert session of April 9, 2024, hosted by Utrecht Province. As an expert in this field, Mathias Lehner was invited to deliver the key note. He took the audience through his vision with appealing nature-inclusive design examples, that increase biodiversity in the city.

The event was hosted by Bob Dijkman-Dulkes, manager of the Provincial accelerator program housing. Consecutive speakers were Remo Wormmeester and Martin Heinen of ecogroen, and Amber Holdijk explaining the experiences of Veenendaal Municipality with a nature inclusive system of points for building projects.

The expert session was part of the accelerator program for housing of Utrecht Province.

On 8th of April 2024 Mathias was chairing the design atelier for nature inclusive building held by Utrecht Province in the Municipality of Zeits.

The Municipality and developer BPD introduced case of former caming are situated on a larger estate to be converted into forest and park dwellings. Landscape architect Bosch Slabbers took on the atelier’s advice to develop a more nature inclusive plan.

The N203 is a provincial road of 2 by 2 lanes that runs for more than 10km as a traffic artery through Zaanstad Municipality. What is the future potential of this highway like road? Originally laid out in meadows at the backyard of the villages along the Zaan river the asphalt strip has become a spatial center piece – and barrier.

Upon initiative of and in collaboration with the Babel architecture centre Mathias is coaching students at the Amsterdam University of Applied Sciences. In autumn 2024 a public exhibition will show the students’ works.

Giulia Gualtier, a PhD candidate at Eindhoven University set a Community or Practice (CoP) on nature inclusive design. Mathias was asked to join this CoP, an international network of experts in the field of design, government and research. A great opportunity to exchange experiences and knowledge to propel urban biodiversity, and a great pool to feed Giulia’s research.

As part of his rol as strategic advisor urban development Mathias explores various sites in inner urban fabrics in order to discover optimal conditions for urban growth addressing the integral needs and challenges in city development.

The findings are used to establish clear guidelines for growth with quality in future studies and urban plans, while at the same time exploring attractive density, connecting the urban weave and indicating the extend of inner urban redevelopment potential.

On October 17th, 2023, Mathias will speak at the Real Estate Dialogue in twin cities Reutlingen ‘the metropole in a bioshere area’ & ‘university city’ Tübingen, together 250k+ inhabitants in the innovative South of Germany. The conference on sustainable regional development is organized by Heuer Dialog in partnership with Instone Real Estate.

Mathias’ lecture will focus on the newest insights when it comes to strategies and benefits, but also cost and return of ‘green’ in sustainable urban development and future-proof real estate.

Other speakers include Max Wörner (robot-driven wood company TriqBriq), Hanno Brühl (Stadtwerke Tübingen, who offer energy, public transport, parking and e-mobility), real estate expert Peter Wilke (GER) and mayors and urban planning directors Angela Weiskopf, Thomas Keck amd Cord Soehlke.


Within the Program of Integral Knowledge of Space for Zaanstad Municipality Mathias chaired the last session before the summer break. On the 4th of July 2023 this event about the spatial problems in the soil took place underground, a more than 800m long space underneath Beatrix Bridge.

The session exchanged knowledge on the various spatial claims in the underground, such as cables, pipes, sewage, city heating and of course soil life and roots for the trees. External expert Jos van der Wersch from Leiden Municipality gave an introduction and reported of a pilot of new vertical order of installations in the soil.
