Buy building land in the canton of Thurgau: undeveloped plots

In the canton of Thurgau, the official geodata analysed show 2'589 undeveloped plots in building zones across 80 municipalities (data retrieved 11.11.2026).

Of these, 1'447 plots carry the mark «Aerial image checked: nothing noticeable». On the evaluated aerial image (swisstopo, flight year 2025), no building and no installation was detected on the plot (except small structures under 12 m²), and no building of 12 m² or more is recorded in the official cadastral survey (status 04.11.2026). Trees and shrubs are possible; in this evaluation, vegetation does not lead to the classification «to be clarified on site». The check is automatic, on our own infrastructure. Every plot is checked on the aerial image and in the official cadastral survey. In two randomly drawn samples of 150 plots each, separate image evaluations supported the finding in 86 to 95 % of cases, depending on the counting method (status 04.11.2026; method: bauland-scout.ch/en/methode.html). The mark is an indicative value and does not replace a site visit or information from the building authority.

Thurgau runs from Lake Constance and the Untersee through the Thur valley to the rolling hills of the Hinterthurgau. Frauenfeld is the capital and German is spoken. Villages, hamlets, orchards and small towns shape the landscape, and building zones often grow out of historic village centres. For a building land search in the canton of Thurgau, Bauland-Scout relies on cadastral survey and zoning data from geodienste.ch, plot by plot. You can find building land among undeveloped plots identified in the official data we analyse, whether or not they are advertised. Where there are enough sales, the dossier includes a price guide from the cantonal tax administration of Thurgau. The municipal building authority and the land registry office will take your questions from there.

The pages for individual municipalities are in German.

Official federal map viewer

Bauland-Scout brings together official geodata and filters out the undeveloped building zones. It does not replace the cantonal geoportal (GIS) or the PLR cadastre: legally binding extracts, the zoning plan and certified cadastral extracts (cadastral surveyor or land registry office) are available from the official authorities.
