Penders is also rare as an early and pioneering example of a site that demonstrates ecological aims in the remediation of a remote coastal landscape. The partially extant plantations on site represent some of the earliest examples of private Eucalypt plantation management in the state. The place is important in demonstrating the principal characteristics of a class of cultural or natural places/environments in New South Wales. Penders is representative of coastal holiday retreats on the south coast. The "Barn" and the Myer House have significance as representative examples of new building types for holiday accommodation, following the introduction of the motel in the 1950s postwar tourism boom. The "Barn" in particular represents an idealised way of living in the Australian climate and landscape in the 1960s. The adjustable blinds, the original lighting on the Barn's Perimeter, and the construction materials taken from the site, demonstrate an early and serious attempt at an ecologically responsible architecture. The "Barn" is an iconic representative example of the work of the fourth phase of Roy Ground's career, between 1960 and 1981, that was dominated by the commission for the National Gallery of Victoria and the Victorian Arts Centre. Both building complexes are listed as of state significance in Victoria.
