The Nyberg-Swanson House is on the National Register of Historic Places and protected by the City of Dania Beach’s Historic Preservation Ordinance.

The Nyberg-Swanson House is significant at the local level in the areas of architecture and community planning and development. The house was constructed ca. 1912 for Charles Nelson, a native of Denmark and one of the community’s early residents. Nelson was a developer of property, a farmer, and a politician active in the political and social life of the city. In 1917, the dwelling was acquired by Swedish immigrants Carl Gustaf Nyberg and his wife, Emmy. They made their own contributions to the economic and political life of the community.

Following the death of her husband in the early 1920s, Emmy Nyberg married John Swanson, also a native of Sweden. Swanson was a successful farmer and served several terms on the town council during the 1930s.

The building is also architecturally significant as an excellent local example of the Colonial Revival architecture style and is the longest example in the city of a dwelling constructed of distinctive rough-faced cast concrete block.

The building should also be considered as a resource removed from its original location, but which is significant primarily for its architectural value, and as the surviving structure, most importantly associated with a historic person and event.
