Eden Project has submitted plans to Cornwall Council to build a £6m hotel at its site at Bodelva near St Austell.
The new 115-bed hotel has been designed to blend into the countryside and have 'high standards of accessibility, energy-efficiency and sustainability'.
There would be no provision for any catering in the building. This is deliberate as the proposal is for sleep accommodation only, allowing the guests to access catering facilities on the main Eden site.
The timber-clad hotel, which would be funded by the private sector, would be similar in style to Eden's Foundation Building which sits outside of the main visitor area.
