Ich war äusserst zufrieden mit der Beratung.

Noma Immobilien und Verwaltung AG was founded in Engelberg in 1973 by Noldi Würsch and Max Albert Krucker, initially focusing on the sale of holiday and second homes in Nidwalden and Obwalden. In the 1980s, the company expanded its activities to include residential and commercial properties as well as its own construction activities as a general contractor. By the end of the 1990s, numerous projects had been completed in Engelberg, Emmetten, Kriens and Seelisberg in collaboration with a partner architect, supplemented by initial management mandates. At the turn of the millennium, the company became wholly owned by Max and Maria Josefa Krucker. With the opening of the Stans branch (in 2003), the company began to focus clearly on real estate brokerage and services, expanding its catchment area to cover the whole of Central Switzerland. The arrival of the next generation – Steven and Daniel Krucker – brought additional expertise in planning, conversion and marketing via new media. The family structure and broad experience enable personalised and efficient customer service. In 2016, the Stans branch was closed and Emmetten has been the main location ever since. To mark its 50th anniversary, the company was gradually handed over to Steven Krucker from 2023 onwards. We are happy to advise and assist you in German, English, French, and Spanish.
