The East Wing of St Thomas' Hospital has been a feature of the Lambeth skyline since the 1960s.
But it now needs repair and modernisation.
The Guy's & St Thomas' NHS Foundation Trust claims that new energy efficient cladding and replacement windows will improve the patient experience, significantly reduce its carbon footprint and save costs.
The hospital is holding a Design Competition for the East Wing Recladding Scheme in conjunction with RIBA (Royal Institute of British Architects) to select the best design for the project and they would like to invite you to comment on the proposals.
An exhibition of the six shortlisted designs will be on display during August at various venues on both hospital sites and in the community.
Hospital staff will be on hand to answer questions and there will be a feedback form so that you can tell them what you think of the designs.
