From the books lying open on a desk, to the linen towels hanging neatly in the bathrooms, the Sonneveld House here has long looked much as it did shortly after its original owner, the industrialist Albertus Sonneveld, moved in with his wife and their two children in 1933.

Anyone visiting the house, which opened to the public in 2001, over the next few months will find the books and towels in their customary places, but will also see them from unexpected perspectives in the reflections on the mirrored floors installed by the Dutch interior and landscape designer Petra Blaisse. As well as creating exquisite visual effects from changes in the climate and light, the reflections expose things that are usually hidden from view, like the servants’ bell concealed beneath a dining table and the soundboard under the piano. They also remind visitors that they are not in a real home, but in a museological reconstruction, by revealing the sensors, alarms and other gizmos with which it is controlled.

Ms. Blaisse’s project, which opened on Sunday and runs through Sept. 13, is part of a series of experiments with which Het Nieuwe Instituut (the New Institute), the cultural center that manages the Sonneveld House, is developing new ways of exhibiting design, architecture and technology. Inviting artists and designers to install their work in “house museums” like the Sonneveld is a proven means of encouraging more people to visit. But Ms. Blaisse has gone further by raising questions about the functions of such places and their presumed authenticity.
