This fine old homestead, called The Valley, was built about 1874 by Allan McLean as the homestead for his very large Waikakahi Station. It is a large weatherboard house built of heart Kauri and roofed with corrugated iron and also pan iron. It has distinctive high gables. The wall linings are of lath and plaster. In all, there were 21 rooms, including four large bedrooms upstairs and large servant's quarters at the back. Downstairs there was a long billiard room with china-blue wallpaper. The Valley had a very good glasshouse and a formal English garden, of which there now remains a large front lawn and many mature English trees. It is one of few early station homesteads in Canterbury to have been built at one time, instead of growing by successive additions, and there have been few alterations. The present owners, Mr and Mrs T Bailey, live in the house.
