What is possibly Cornwall's tiniest office, known as the Tardis House, is on sale for nearly £20,000. The 7ft by 6ft building, close to Truro's cathedral, has room for a table, chair, computer and very little else.
The building, originally built as a loo, is being offered for sale with a 125-year lease at £19,950. A business is currently being run from the site, which is built over the river on Wilkes Walk.
"It is the smallest office building we have ever sold," estate agent Neil Sargent from Stratton & Holborrow said. "I can stand in it with my arms outstretched and touch the walls. When there's two of you in there it gets pretty friendly."
