[3][4] Many of Ludwig's Bauhaus-style furniture designs for the Hochschule für bildende Künste were mass-produced and used for decades,[1][2] and he outfitted some shops on the Kurfurstendamm.
He designed the Berlin pavilion for the International Traffic Exhibition in Munich in 1953, consisting of a box of fibre cement on stilts.
[3] He designed many open-plan bungalow houses inspired by Mies van der Rohe's Barcelona Pavilion and also by Sep Ruf.
[3] Ludwig won out over 324 others in the competition to design the monument to those who died during the Berlin Airlift of 1948–49,[2] although for reasons of cost and materials shortages, the aluminium cladding he had specified was replaced with reinforced concrete.
His design was also selected for what is now the Protestant Church of St. Martin in the Tegel district of Berlin, which was completed after his death by his friend and colleague Karl Otto.
