In January 1918, the Swedish King in Council proposed creating a ministerial position in Helsinki.

Foreign Minister Johannes Hellner commented that, given Finland's new status as an independent state, it was essential to establish a diplomatic mission in Helsinki as soon as possible, with a minister and a legation secretary.

[1] In September 1954, the Swedish government decided to elevate the legation in Helsinki to an embassy, and at the same time the current envoy, Gösta Engzell, was appointed ambassador in Helsinki.

It was originally designed by architect A. F. Granstedt, but after becoming a diplomatic mission, it was heavily changed.

The architect of this was Swedish Torben Grut, who designed it to look like the Stockholm Palace.
