Hofanlage Osterholzer Straße 11, Traditional farmstead in Syke, Germany.

Hofanlage Osterholzer Straße 11 is a protected farmstead in the Osterholz district of Syke, Lower Saxony. Its main building is a two-post hall house with timber framing and red brick infill, a half-hipped roof and a Low Saxon gable with an owl hole. A separate timber-framed barn with red brick infill has a tiled hipped roof; a timber-framed granary under a saddle roof was demolished with permission in 2008.

Osterholz was first recorded around 1250 as Osterholte in the Bremen Weser bridge list. The farmstead's timber-framed buildings with red brick infill date from later centuries; the storage building under a saddle roof was demolished with permission in 2008. By 2012 the remaining buildings stood in a very dilapidated state and were no longer in use.

The farmstead's name comes from Osterholz, first recorded around 1250 as Osterholte in the Bremen Weser bridge list. The residential and commercial building is a Zweiständer-Hallenhaus, a two-post hall house with a Krüppelwalmdach (half-hipped roof) and a Niedersachsengiebel (Lower Saxon gable) featuring an Uhlenloch, an owl hole. The barn is a timber-framed building with red brick infill and a tiled hipped roof.

The property is viewable from the street, allowing visitors to study the architecture and facade details from outside. The exposed timber framing makes it easy to understand the traditional construction techniques used throughout.

The gable of the Zweiständer-Hallenhaus carries a Niedersachsengiebel with an Uhlenloch, an opening traditionally left for owls. The farmstead also had a timber-framed granary under a saddle roof, demolished with permission in 2008; by around 2012 the remaining buildings stood unused and in a very ruinous state.
