 Three of the original buildings of Barrhill plus the gatehouse at Wason 's homestead were constructed of concrete , and they still exist to this day . One of those buildings , St John 's Church , is registered by Heritage New Zealand as a Category II heritage building , and the gatehouse is a museum that is open on request . Today , few buildings exist in the village , but the formal layout of avenues still exists , giving the setting a charming appearance .
