Conceptual design to convert the barns to residential accommodation.

Treboul Farm Barns, St Germans

During the 19th Century, Isambard Kingdom Brunel extended the Great Western Railway into Cornwall but included gaining a license from the Port Eliot Estate to enable the lines to cross over land owned by the Estate and to construct the various elements of infrastructure to enable the proper operation of the railway extension.

Searches at the County Records Office revealed some original drawings.  Sadly the barns were not constructed with all the features of the original design, but they are significantly influenced by railway design of the time.  The barns are listed buildings.

The Listing details taken from ref. No.4400765 – 05/0164/2
