Since all the required wiring and piping (for the safety and preservation of the palace and the Paleis Het Loo collection) has been installed, specialist construction companies are reinstalling the original wooden wall panels and floorboards.  

In the palace, the library regains the original shape and layout. The wooden cabinets and floors have been fitted back into place with preciscion and craftsmanship. When reopened, the bookcases will be full of books again.

The Underground Expansion is almost completely closed. The glass parterres on the Bassecour provide natural light in the Grand Foyer below. In the exhibition rooms light will be staged to display the collection, all the while protecting the pieces against the harsh light from outside.
