query: What are the proposed redevelopment plans for specific locations within Elm Grove, Brighton?
answer: There are several redevelopment projects mentioned in the text.  One involves demolishing Ainsworth House and building a higher-density high-rise "family complex" (Balchin Court). Another project involved demolishing former nurses' homes and replacing them with flats and a community centre.  A lapsed plan involved the partial demolition and redevelopment of a detached villa at number 18 Wellington Road.  Redevelopment of the former railway cutting created William Clarke Park.
