The Musgum houses in Cameroon are made from compressed sun-dried mud. Their dome shape are very close to the catenary arch, the ideal mathematical form for maximum rigidity with a minimum of material. As well as being decorative, the raised pattern on the outside wall contribute to the drainage of rain and access to the top of the building for regular maintenance of the coating.

Casa Batlló was originally built between 1875 and 1877. In 1900 it was bought by the rich industrialist Josep Battló i Casanovas who commissioned Gaudí to tear down the old house and reconstruct a new one. Gaudí however convinced Battló to remodel the existing building. Between 1904 and 1906 Gaudí redesigned the facade and roof, added an extra floor and completely remodeled the interior.
