Tillbergska villan, Residential building in Diplomatstaden, Stockholm, Sweden.

Tillbergska villan is a palace-like villa at Laboratoriegatan 10 in Diplomatstaden, designed by Ivar Tengbom and built in 1918–19. Its plastered facades are painted an old rose tone, one of only three villas in the district not in red brick. The plan forms a mirrored C around a courtyard, with a stair tower and a long balustraded balcony facing the inner yard.

Knut Tillberg applied for a building permit on 3 July 1917, attaching plans by Ivar Tengbom dated 9 June 1917. The villa was built in 1918–19; Tillberg lived there from 1920 to 1923, and Axel Wenner-Gren moved in during 1924. From 1977 to 1989 it housed Dansmuseet, and since 1993 the South Korean embassy.

The villa is one of only three in Diplomatstaden with plastered facades; the other nine have red brick. Its name comes from Knut Tillberg, who lived here 1920–1923, and it was long called the Wennergrenska palatset after Axel Wenner-Gren. Since 1993 it has housed South Korea's embassy, so the former ballrooms and salons now serve diplomatic work.

The building faces Laboratoriegatan to the north and Nobelgatan to the south, with its main volume along Nobelgatan. The 2,043 m² plot is almost entirely built over, leaving only a narrow courtyard. Since 1993 it has housed the South Korean embassy, so only the exterior can be viewed.

The property features a mirrored C-shaped floor plan that wraps around a central courtyard. This unusual layout with a distinctive balcony and turret on the southern side creates an interesting architectural composition.
