Paisley Museum and Art Gallery has a map dated 1864 on which Wotherspoon and his agents, Reid and Henderson, writers, extol the virtues of their new venture. The map shows Castlehead with the housing plots marked and conforming fairly accurately to the layout that has survived to the twenty-first century. A note in the bottom right corner states "The ground is beautifully situated, commands the finest views around Paisley, has fine southern and western exposures, is within a seven-minute drive of the railway station, and the soil is of the richest nature".
