Cabin Park was Douglas Cook’s major extension of the garden in the mid 1930s. He set out a series of tracks up the hill at the north western end, and in 1936 built his ‘Canadian Cabin’ and planted material he thought was frost tender.

Along the gullies in between the house garden and the Burma Road, he set out more extensive areas of conifers, planting groups of them for effect.

The variety of material available from New Zealand nurseries was quite extensive and varied, some material such as Xanthcerus sorbifolia & Fokenia hodginsonii were not to available again in New Zealand until the 1990s.
