The steps taken to clean up London were :
(i) Attempts were made to decongest localities, green the open spaces, reduce pollution and landscape the city.
(ii) Large blocks of apartments were built Iike those in Berlin and New York.
(iii) Rent control was introduced in Britain during the First World War.
(iv) Demands were made for new 'lungs' for the city and some attempts were made to bridge the countryside through ideas as the Green Belt around London.
