Casson's vision for Dorset House was that of a 'community where every individual was encouraged to feel that she had a real object'. Having seen the benefit, in the United States and at Octavia Hill, she combined medical interventions with education and recreational approaches. She actively involved herself in the daily therapeutic activities, often inspired by her artistic childhood and build closer relationships between patients and staff, creating a community feel. At one point she even cast herself in Dorset House's drama production, playing Mr. William Collins in their 1934 rendition of "Pride and Prejudice".
