Part of the ambience of country house hotels is due to their British origins and thus their natural focus on gardens. From the outset, the transformation of Langdon Hall from a private residence into a luxury country house hotel as envisaged by its founders architect William Bennett and Mary Beaton, embraced the British tradition. There would be significant gardens at Langdon that combine restoration of earlier gardens and development of new landscapes.

To compliment the English ambience that is alive inside Langdon Hall, much has been done to renovate the grounds and gardens to their original Victorian magnificence.

Dr. Leslie Laking, retired director of Hamilton's Royal Botanical Gardens, worked with landscape artist Owen Scott and Langdon Hall's gardeners, tracing the long-lost shapes of the flower beds and making an inventory of trees.

With the help of old landscape drawings, the gardens have been restored. In 1991, Langdon Hall's head gardener put in a large Kitchen Garden, growing fruits, vegetables, herbs and edible flowers for the chef's to use in his dishes.
