What the buyer is looking for
The assignment concerns the architectural development of the renovation, including the outdoor space, of the Montessori Vaklyceum at Vondellaan 83 in Groningen. The task includes the preparation, design and further elaboration of a future-proof educational housing, in line with the ambitions of Public Education Groningen and the municipality of Groningen. The renovation consists of the preservation of approximately 1,300 m ² of the existing building from 1968 and the realization of approximately 4,000 m ² new construction, together approximately 5,300 m ² BVO. The existing building from 1968 represents an important cultural-historical value and is therefore not only an existing building that is preserved, but an essential starting point for the design task. In addition to the building, the direct outdoor space is also part of the design task.
