According to the London Evening Standard council workers claimed they found rubbish - including plastic food wrappers, glass bottles, rubble and faeces piled as high as 1.5 metres in the house.
Upstairs in the bedroom there was just two foot of standing room.
The house has since been boarded up to prevent Ms Towers from returning, she told the Evening Standard: "I'm okay, I will go and stay with some friends in Snaresbrook. It will be a new start."
Rozmin Najak, 26, who lives opposite told the paper: "We thought she was dead. We had not seen her for a week, and she was not the type to go on holiday."
The waste disposal company involved in clearing the house claimed there was "at least 20 tonnes of stuff in there."
A spokesman for the Metropolitan Police said they were called to the scene on Tuesday by reports of "a person trapped behind closed doors".
He added: "Police and London Fire Brigade (LFB) attended the scene. On arrival the structure of the address was found to be unsafe due to the collapse of the front room ceiling."
