The scheme for developer Sherwood Street - replacing a 1950s pub - would include seven residential units and one live-work unit.
However, Trentham has warned that the building, clad in Cor-ten, is likely to have trouble with planning due to the attitude of the local conservation officer. Officials have told him that his project is not in keeping with the surrounding 'pattern-book' housing.
Trentham has attempted to argue that the Cor-ten cladding reflects the iron-and-tinware works that were replaced by the existing homes.
Trentham said: 'We have spent a year developing the project with Southwark Council and although it is not in a conservation area we have been frustrated by the conservation department's insistence on keeping in context with the surrounding housing.
'[This housing] is completely out of character with the previous warehouses that were on the site and that formed the rich heritage of Bermondsey - in stark contrast to the contemporary urban vernacular previously supported by the council.
'It is important to rise above this mediocrity of the surroundings and not dumb down to its level.'
