Casa Kuschel, Historical mansion in Puerto Varas, Chile.

Casa Kuschel is a mansion in Puerto Varas featuring distinct wooden cladding patterns across its levels and a prominent tower structure. The building combines horizontal wood paneling on its lower floor with vertical paneling above, supported by two substantial structural elements.

Bernardo Kuschel commissioned Casa Kuschel as a residence, built around 1915–1917 in the eclectic style of the Llanquihue Lake chalets. It is one of the few surviving early houses of the German colonists who settled near the lake from the mid-19th century, alongside the Götschlich, Jüpner, Maldonado, Yunge and Raddatz houses. Chile declared it a National Historic Monument by Supreme Decree 290 of 4 June 1992.

Casa Kuschel is one of the few surviving early houses built by German settlers who reached the Llanquihue Lake area from the mid-19th century; the Götschlich, Jüpner, Maldonado, Yunge and Raddatz houses are its companions. Its name recalls Bernardo Kuschel, who commissioned it as a residence. The eclectic facade mixes Bavarian Baroque on the tower, Neo-Gothic on the eave brackets and friezes, and Neoclassical window surrounds.

Casa Kuschel stands on a 1,168.1 m² lot in Puerto Varas, with the house itself covering about 796.6 m² over a main floor, an attic level and a basement. Since September 2024 it has housed the Patagonia Biotech Hub, and a marine-products shop run by AquaChile operates in a side space. Visitors can view the exterior and the eclectic tower from the street.

The house belonged to the Pumalín Foundation, formerly Douglas Tompkins's, and housed the Puerto Varas offices of Pumalín Park. Since September 2024 it has been the seat of the Patagonia Biotech Hub, with an AquaChile seafood shop in a side space.
