It was then owned by the merchant and leading citizen in Stavanger, Gabriel Schanche Kielland (1760-1821).

He gave the estate its present name after the last letters of his and his wife's names: Gabriel Schanche Kielland, Johanna Margaretha Bull.

The estate is today a royal residence, a museum and the representation building of Stavanger municipality.

[2][3] In 1989 a painting of the residence was displayed at Nasjonalgalleriet as a part of the exhibition Kulturminner i norsk kunst.

The painting was reviewed and commented during the opening day tour by King Olav V.[4]
