A transcript of the BBC television interview, details of which have been obtained by the AJ, sees Farrell warn of the creation of 'ghettos' if too many houses are built in the area.
The architect has claimed that alternative proposals would be much more beneficial to the Thames Gateway.
These alternatives, designed by him, would turn the region, which stretches from London to Margate, into a national park, with wildlife areas mixed with sustainable housing.
When questioned about the proposals, Farrell said: 'I'm not saying we shouldn't build houses.
'But we need to create a desirable environment first. If we simply build on brownfield sites, effectively creating whole villages from nothing, we are in danger of repeating the ghetto effects of the '60s.'
Speaking in June (AJ+ 28.06.05), Farrell accused the government of being too committed to economic arguments to the detriment of good design in the Thames Gateway.
Speaking at the Public Design Review of his proposals for a new National Park for the Thames Gateway, Farrell said there was a problem with the attitude of Westminster decision-makers.
Farrell's comments can be seen on Inside Out, which will be screened on BBC1 at 7.30pm this evening (26 September).
