Around 1928 the pair collaborated with Charlotte Perriand to design a line of furniture that incorporated modern simplicity and industrial materials for the Villa Church outside of Paris. The line included the iconic chaise lounge (LC4) and the Fauteuil Grand Confort, petit modèle, both presented at the Salon d'Automne in 1929. Other noteworthy accomplishments include the partnership’s first place design of the League of Nations building in 1926, and their plan for the new Punjab capital city in India, Chandigarh. After construction of the massive urban planning project was complete, Jeanneret stayed on as Chief Architect of the city for over a decade.
