The enclosing yew hedge around the pond garden is a typical feature of period. The lime tree avenue which is north of the palace gatehouse was built sometime between 1894 and 1912–13 according to the Ordinance Surveys of those periods. The Victorian glass house was built in 1890 by Mckenzie and Moncur from Edinburgh for Lord Bute and was used mainly to grow flowers and exotic plants. Plant hunting was popular at that time and wealthy people would travel the world to find specimens, and plant in their gardens for display to friends. There is also evidence that there was a second glass house in the garden near the existing one.
