Utrechtseweg 301 is a single-tenant office building in an authentic long-house farmhouse, originally built in 1770, on the Sandwijck estate in De Bilt. It has been rebuilt several times and was last partly renewed in 2021 with a focus on sustainability. A walking route across the estate, past meadows and winding water features, starts less than a minute's walk from the building, and the A28 and Utrecht Science Park are a short distance away.
