The projects represent a fresh attempt to regenerate a place which has become synonymous with the classic cult film A Clockwork Orange.
The two schemes, for the Gallions' Housing Association, were commissioned to act as landmarks for a major thoroughfare.
One of the schemes is on the site of an old boilerhouse, while the other will replace a redundant boxing club. Together they will provide 109 new residential units.
'Together, the developments hold the potential to form a new edge to the southbound carriageway of Carlisle Road,' director Sue Konu said. 'This is an opportunity to create two new striking urban statements that will signal regeneration in Thamesmead.'
