Das Norwegische Holzhaus, Timber-framed house in Wuppertal, Germany.

Das Norwegische Holzhaus at Kohlstraße 64 in Wuppertal-Uellendahl-Katernberg is a single-storey, gable-fronted house with a saddle roof, set on a rendered masonry base. Its timber-frame construction was originally filled with triple wall boarding, and the bays carry plank layers. The south-west gable faces the street with two axes and red shutters on the ground-floor windows; the roof overhangs with decorated bargeboards. A later terrace with a lean-to roof on wooden posts runs along the north-west side.

Banker August Freiherr von der Heydt bought the house at the 1900 Paris World's Fair and had it moved by rail to Elberfeld after the fair closed in 1901. It was set up in the Mirker Hain beside the dance hall known as "Waldhaus Sanssouci", now gone, and opened as a restaurant in 1905. It was listed as a monument on 19 November 1992.

The name comes from the Norwegian architects whose prefabricated wooden houses were shown at world's fairs around 1900. This one, designed as a dwelling, was bought by banker August Freiherr von der Heydt at the 1900 Paris exhibition and reopened in 1905 as an excursion restaurant. From May 2006 a tenant ran it as "The Old Woodhouse", serving rustic American food with occasional live blues.

The house stands at Kohlstraße 64 on the edge of the Mirker Hain in the Uellendahl-Katernberg district. The south-west gable with its two axes and red shutters faces Kohlstraße; the later terrace with its external wooden posts and iron-railed stair lies on the north-west side. The building was closed as a restaurant from October 2008 and has been used as an insurance office since May 2018, so it is seen from the street rather than entered.

The house was bought by banker August Freiherr von der Heydt at the 1900 Paris World's Fair and moved by rail to Elberfeld after the fair closed in 1901. It was set up beside a dance hall called "Waldhaus Sanssouci", which no longer exists.
