Although he was chiefly known for his work for the Roman Catholic church, he also worked on a number of secular public buildings and developments, and carried out many renovation and restoration projects on "historical" churches in German-speaking German speaking central and eastern Switzerland.
[2] His father, Alois Moser (1900–1972), was also responsible for a number of important new Catholic churches, including those in his home town of Würenlos (condemned at the time by locals as "much too modern"), Untersiggenthal and nearby Killwangen.
He entered a number of architecture competitions which led to a series of commissions for new Catholic churches in German-speaking German speaking Switzerland.
The development has subsequently undergone extensive repairs, but the "brutalism" of Moser's 1970s designs has been respected.
His contributions include the Grünau retirement home, the school building, the kindergarten and the public swimming pool, which between them set the architectural tone for the overall development.
