The project will form part of Nottinghamshire County Council's bid to book a place in the next stage of the Big Lottery Fund's Living Landmark's grant programme.
The scheme, called 'Sherwood Forest: The Living Legend' is one of six regionally significant community regeneration projects to have been shortlisted for the upper stream of the Living Landmarks funding.
Each of the shortlisted projects has been awarded a development grant to progress their application, which is due to be submitted in May 2007.
The RIBA competition office is inviting expressions of interest for the 3,000m 2multi-purpose visitor complex for the sustainable development of Sherwood Forest.
It will need to balance visitor experience with the environmental needs of the forest, together with the social and economic benefits to the local community.
Up to six teams will be invited to develop design proposals, with each of the shortlisted teams receiving an honorarium of £4,000.
The expression of interest deadline is 1pm, Friday 13 October 2006. For more information please visit www.architecture.com/competitions
