The ambassador's responsibilities included maintaining continuous dialogue with the Belgian government, especially regarding EU affairs, and fostering economic and cultural ties between Belgium and Sweden.

[4][5] From 1 April 1944, Gunnar Hägglöf served as envoy extraordinary and minister plenipotentiary to the Belgian government in exile and the Dutch government-in-exile in London.

According to Foreign Minister Carl Bildt, the decision was a consequence of the Riksdag deciding to cut the grant to the Government Office by SEK 300 million.

The consulate general's focus is consular activities, including ensuring readiness to assist individuals in crisis or disaster situations.

[15] The ambassador's task was to conduct ongoing dialogue with the Belgian government, particularly on EU matters, and to promote the economic and cultural relations between Belgium and Sweden.

[19] With the German occupation of Brussels in 1916, the mission moved to Hotel des Indes in The Hague, Netherlands, which was neutral during the war.

[29][30] From 2000 until the closure in 2011, the address was Sweden House, Rue du Luxembourg 3, a few hundred meters from the Royal Palace of Brussels.

[31][32] In 1928, on the initiative of then envoy Gustaf von Dardel, the Swedish state purchased the house at Avenue Géo Bernier 13 in Ixelles.

It includes ceramic relief panels on the back, which are replicas of Andrea della Robbia's decorations on Brunelleschi's Ospedale degli Innocenti in Florence.

At the time of acquisition, renovations were carried out, including the conversion of the architectural firm's office into a banquet hall and the construction of a fireplace with the Swedish national coat of arms.

This included the roofs, façades, entrance, hall, staircase, and landing, along with three rooms on the first floor facing the street, as well as the lower gallery at the back.
