Von Veltheimsches Haus in Braunschweig, Timber-framed house at Burgplatz, Brunswick, Germany.

Von Veltheimsches Haus is a timber-framed building with three residential floors and a multi-story bay window that rises prominently across its front. The structure displays characteristic features of late Gothic and Renaissance design with elaborate carved details.

Achatz von Veltheim auf Harbke and Margareta von Saldern had the house built in 1573, as an inscription with two coats of arms above the passage still records. In 1944 the NSDAP district leadership moved in after the Villa Rimpau was damaged in the 15 October bombing; it stayed until the city was handed over on 12 April 1945. US military administration under Colonel Brodie took over on 15 April, and command passed to British forces on 5 June 1945.

Above the side passageway, an inscription with two coats of arms records the builders: Achatz von Veltheim auf Harbke and Margareta von Saldern, married in 1573, the year the house was built. The carved diamond band on the sills and the horseshoe-shaped rows of beads on the posts are ornaments taken from stone architecture.

The house stands on the north side of Burgplatz, next to Brunswick Cathedral, and is used today by the Braunschweig-Lüneburg-Stade Chamber of Crafts. Visitors see the timber facade from the square; the side passage and the bay window with its 1868 renovation date are best viewed from the street. The building was renovated in 1974/75.

The building features an unusual architectural element called a Frauensitz, a bay window construction that extends through multiple floors and forms a distinctive part of its structure. This type of multi-story window design was favored in wealthy homes during the late medieval and Renaissance periods.
