The Binnenhof has said goodbye to its residents and the research phase can finally begin. Splinter looks back with former Binnenhof residents who said goodbye to their special time there. He walks through the building with architect Frank van der Vecht, among others, to see what is left of the original state of the building.

He also visits the House of Representatives with former parliamentary reporter Ron Fresen and usher of the House of Representatives Sarah Baronete.

Minister Hugo de Jonge updates Splinter Chabot about the costs incurred and all the defects that have come to light. Splinter looks with architect Joep Mol at what the new public entrance to the Senate will look like. The public will soon walk under one of the most special ceilings of the Binnenhof. Together with former Senate Presidents Yvonne Timmerman-Buck and Ankie Broekers-Knol, Splinter wanders through the corridors of the Senate. Historian and theater maker Eveline van Rijswijk highlights various special women from the history of the Binnenhof.

Architects Camiel Berns and Eric van Noord examine the former Hotel Central from 1911, part of the House of Representatives, during the renovation. Berns and Van Noord are determined to bring back the atmosphere of the past with a modern twist and show Splinter how they will do that. Color history researcher Judith Botan also hopes to restore the rooms in the former Ministry of Justice of the House of Representatives to their former glory and she tells Splinter about a special and very expensive wallpaper from that time.
