The Swansea Foyer project - the first of its kind in Wales - offers affordable accommodation, personal development support and access to training and employment for vulnerable young people aged between 16 to 25.
Mrs Hart said: 'I am delighted to have the opportunity to view the work of the Swansea Foyer. The 'joined-up' approach adopted by the centre recognises that the needs of homeless youngsters is neither simplistic nor one-dimensional.
'As is so often the case with the most vulnerable groups within society today, the real solutions to the problems of homeless youngsters cannot lie within a single focus, but rather in tackling a complex combination of housing, support, training and employment needs.'
The centre is managed by Tai Trothwy - formed last year by the merger of Gwalia Housing Group's Community Care Department and the former Trothwy Housing Association. It is part of a rapidly-growing UK movement which began life in 1992.
There are now four other operational foyers in Wales at Cardiff, Port Talbot, Wrexham and Newtown.
At the end of their stay in the foyer it is hoped that young people will have the skill and confidence to obtain and sustain permanent employment and be able to live independently as fully-integrated citizens.
