London-based architects Carmody Groarke have submitted a planning application to the Lake District National Park to redevelop the Windermere Steamboat Museum into a heritage attraction.

The £13.4m museum development will include exhibition space, a wet dock to display heritage boats and a conservation workshop open to the public.

Highlights of the collection will include: steam launches of the 1890s and 1900s; SL Dolly (1850) - the oldest mechanically powered boat in the world; and Beatrix Potter's tarn boat that she used to sketch in on Moss Eccles Tarn.

In addition to core display space, the museum will feature a learning centre and café with views to the north of Windermere.

The completed museum is expected to attract 100,000 visitors a year and 200-300 school groups.

It will create 94 direct and indirect jobs and create training and apprenticeship opportunities.
