Korshagehus, situated at Korshage Fjordvej 1, just north of Rørvig, Odsherred Municipality, Denmark, is a Modernist summer house constructed in 1960 by architect Erik Korshagen for his own use.

They are all constructed in timber with steep, thatched roofs to a Minimalist design with inspiration from Japanese architecture.

The summer house is located on top of a former coastal cliff whereas the two other buildings are situated at the foot of it.

A plastered and black-painted brick basement has later been added below the central part of the building to provide support for the timber structure.

The southern portion of the building contains a large living room, partly separated from the adjacent kitchen by the central brick core with fireplace and cupboards.
