Derek and his partner Kenneth Partridge were at No. 8 Chichester Terrace (which was only rented) from 1952 until 1964 when Derek bought flat No. 7, 10 Chichester Terrace.
They remained there until some date towards the end of the seventies when he bought flat 5, No 9 Chichester Terrace and knocked No. 7, 10 Chichester Terrace and flat 5, 9 Chichester Terrace into one single flat running across the two houses.
