Gerloffsche Villa, Architectural heritage monument at Löwenwall, Brunswick, Germany.

The Gerloffsche Villa at Löwenwall 16 is a Gründerzeit mansion built in 1888/89 by city architect Ludwig Winter. Its show façade has a white stone ground floor with a loggia, a red-brick bel étage with three arched window pairs, and an Italian-style flat roof. Because the site slopes, only two storeys and a mezzanine face the street, while five storeys face the garden.

The building was constructed between 1888 and 1889 by architect Ludwig Winter for sugar wholesaler Georg Ernst Ludwig Gerloff and his family. It emerged during a period when wealthy merchants in Brunswick were outfitting their homes with new technical and design features.

The villa's Italian Renaissance style shows in the white stone ground floor with its loggia and the red-brick upper floor with three arched window pairs. The loggia gable carries a sugar loaf and a sugar beet, and the side entrance bears the monogram L.G., both referring to owner Louis Gerloff's sugar wholesale trade. In the octagonal vestibule hangs a large porcelain Brunswick lion from the Fürstenberg manufactory, one of only eleven examples.

The building is easily visible from the outside and sits at a central location in the city center. Visitors should know that the interior now houses administrative offices and not all areas are open for public viewing.

The house was one of the first in Brunswick to feature central heating, which was quite rare for private residences at that time. Inside, carved dark wood rooms and design elements reference the sugar trade of its original owner.
