Ländtestrasse 1–13, Residential ensemble of New Building in Neustadt Nord, Biel/Bienne, Switzerland

Ländtestrasse 1-13 is an architectural ensemble in Bienne's New City North district featuring several residential buildings with clean geometric forms and well-proportioned facades. The structures display the local modernist approach to housing: functional, light-filled, and without unnecessary ornament.

The five houses were built in 1930 and 1933 as part of the Bahnhofquartier north of Biel station, laid out between 1927 and 1948 under Neues Bauen rules. City architect Otto Schaub (in office 1925–1947) imposed special regulations for the Ländtestrasse plot requiring a modern building form and flat roofs. No. 13 housed the showwoman Marguerite Weidauer-Wallenda until 1969. The row was listed as protected in 2003, No. 1 following in 2015.

The street takes its name from the Schiffländte, the former lake landing stage. No. 13 housed the showwoman Marguerite Weidauer-Wallenda until 1969. The row belongs to the Bahnhofquartier, built 1927–1948 under city architect Otto Schaub, whose special rules required flat roofs and a "modern building form".

The five houses stand between Ländtestrasse and the railway tracks running northwest to southeast in Neustadt Nord, north of the Schüss. At No. 17 by the Unterer Quai, the 1953 electricity substation, repair tower and switch hall adjoin the row. The lakeside ground is green, and the Gymnasium Biel-Seeland occupies the southern end.

House number 13 was home to the showwoman Marguerite Weidauer-Wallenda until 1969. The corner house at number 1 was designed by city architect Otto Schaub himself as his own home, and its garden now serves as a car park.
