Haus Lange and Haus Esters are two residential houses designed by Ludwig Mies van der Rohe in Krefeld, Germany, for German industrialists Hermann Lange and Josef Esters.

Hermann Lange and Josef Esters established in 1920 the "Vereinigte Seidenwebereien AG" (United Silk Weaving Mills Company), or Verseidag.

[7] In 1927, Josef Esters and Hermann Lange commissioned the design of two adjoining houses to the architect Ludwig Mies van der Rohe.

Closed on the street side, both have high windows that open onto a landscaped garden.

The gardens alternate grassed areas, paths and flowerbeds according to geometric principles that evoke the continuity of interior and exterior spaces.
