Inkognitogata 27 (1906–present)

The chancery and residence is located at Inkognitogata 27 in the Uranienborg neighborhood in the borough of Frogner. The house was designed by the Norwegian architect Ove Ekman and was built in classicist style in 1872–1873. The house dates back to the 18th century when it was part of a country estate just outside the city limits. Today, the property's surroundings are made up of the Royal Palace and the Palace Park. From the beginning, the house had a rectangular building, two floors and a plastered facade. The owner of the house, wholesaler Adolph Holter and his family, lived here until the end of the 19th century when Holter had such great financial problems that he had to sell. The house was purchased by the Swedish state in 1906 for SEK 100,000 and is the third oldest state-owned Swedish property of the Swedish foreign service after the one in Istanbul (1757) and the one in Madrid (1904). In connection with the purchase, the house was rebuilt to partly create a building with a more Swedish character, partly to adapt the house for its new purpose as a chancery and residence. Another floor, to accommodate the chancery and guest rooms, was added as well as extensions for the kitchen, serving room, entrance hall and veranda. The facades were also replastered.^[3] The rebuilding in 1906–1907 was led by the Swedish architect Fredrik Lilljekvist.^[4] Until the end of World War II, the house functioned as both a chancery and residence for the Swedish envoy and his family.^[3] From 1945, temporary premises were rented in the area until the chancery moved into newly built premises at Nobels gate 16 in 1957. Areas that were vacated with the move in the house on Inkognitogatan were converted, among other things, into guest rooms and a chef's residence. Somewhat later, a gatekeeper's house was also built in the style of the main building.^[3]

As both houses on Inkognitogata and Nobels gate were too large and had empty areas, the solution was to combine all functions at one address.^[3] In February 2017, the National Property Board of Sweden petitioned the Swedish government to carry out the reconstruction of the residence for an estimated SEK 30 million, and in August of the same year the project was given the greenlight.^[5] In 2018–2019, a reconstruction by architect Bo Hofsten took place. Renovation and adaptation was done to re-house the chancery in the same building as the residence.^[3] When the National Property Board of Sweden began the renovation in 2018, the residence consisted of a basement, two floors and an attic alongside a couple of smaller houses such as a garage and a gate house. Interior-wise, the renovation has mainly concerned the attic, which was converted to function as a chancery. When the house was empty, all surface layers, where there was a need, were also refreshed. Externally, the garage was demolished and replaced with a new building of the same size, in the same location. The building's new entrance and the consular office were moved here. The front door was artistically designed by Göran Strååt in the 1950s and has been moved from the former chancery. Accessibility was also significantly improved during the renovation by adding a new accessible lift, an accessible toilet and a lifting table in the consular office. In terms of energy, the biggest improvement was the old electric boiler which was removed and that the house has been connected to district heating instead. The project in Oslo was in line with the National Property Board of Sweden's work to contribute to the global goals in Agenda 2030 and the goal of social sustainability.^[5] In 2019, the residence and the chancery were inaugurated by Foreign Minister Margot Wallström in the presence of the National Property Board of Sweden's Director General Ingrid Eiken Holmgren.^[5]
