Wellesley College is a boys-only independent primary school in Day's Bay, Eastbourne, New Zealand. Day's Bay House was built in 1903 for the Wellington Steam Ferry Company Limited which had made the heart of Day's Bay a destination resort and sports complex. The hotel operation met with only moderate success and in 1913 with its immediate surrounds, 4 acres, it was sold to Miss Gladys Sommerville so she might expand her successful Croydon School then at 81 Hill Street Thorndon. With little or no change Day's Bay House became Croydon Preparatory School for Boys. The old croquet-lawn became the sports field and in the 1920s the hotel's bowling-green became the boys' tennis courts. The rugby field remained at the southern side of the driveway but was not part of school grounds. The Pavilion and its amusements like the ferries and their wharf became part of (out-of-bounds) school life. Upstairs on the northern side two pairs of bedrooms became dorms 1 and 2 and the upstairs guest sitting-room became dorm 3. Ultimately the (lightly) enclosed upstairs central verandah became a dormitory for the bigger boys.
