The center is a two-story wood frame structure, 2-1/2 stories in height, with a dormered gable roof and a three-story circular observation tower at one corner. The roof extends down to shelter a porch that encircles the building. The exterior walls are finished in wooden clapboards, with bands of decoratively cut wooden shingles. The structure is built directly on a ledge that slopes down to the shore, where there is a rocky beach.
