Both the façade of the Trippenhuis complex and one of the outer walls adjoining the courtyard have recently been cast in bronze. On the video you can see how craftsmen of Royal Eijsbouts cast a mold intended for the two bronze panels of the complex. Office Winhov has opted for bronze to create more unity with the adjacent historic building on the Kloveniersburgwal 29. Both parts are owned by the Central Government Real Estate Agency and house the Royal Netherlands Academy of Arts and Sciences. Office Winhov is in charge of the transformation and renovation of the reception and public rooms, as well as the long-term vision for the restoration of the historic complex. HOEK architecture & preservation is responsible for the renovation of Kloveniersburgwal 29.
