Tynecastle underwent substantial changes in the early twentieth century. A small stand and pavilion were built in 1903. The banks of terracing were greatly increased in 1906, giving a total capacity of 61,784. In 1911, a covered enclosure was erected on the western "distillery" side. The two old stands and pavilion were replaced in 1914 by a pitch-length grandstand (the present Main Stand), designed by the renowned stadium architect Archibald Leitch. To partly fund the cost of the new stand, Hearts sold Percy Dawson to Blackburn Rovers for a British record transfer fee of £2,500. A number of items were omitted from the first estimate of the stand, which meant that its cost doubled to £12,000.
