To be able to continue this kind of research, it appeard necessary to expand the current housing at the Uithof in Utrecht. The Westerdijk Institute is housed here along with the Hubrecht Institute of the KNAW, for which Aronsohn recently expanded the building with a new part.

The expansion of the Westerdijk Institute included offices, a cryo-freezer area for the fungus collection, a refregirator, a biophysical lab, two BSL-2 labs and a BSL-3 lab. The designation BSL stands for Biosafety Level. BSL-3 is the second highest level of security and meet very high requirements to air management, air density, furnishing and completion of the room. Building such a lab required a lot of the designers and contractors.

Aronsohn has guided the entire design and implementation process. For the contractors the phase A/B method was applied.
