Sometime between 1842 and 1851, Joihn Moore hired Weston architect, William Tyrrell, to design the house that still stands at 11 Great Oak Drive. Tyrrell was an important local architect and builder.  Other examples of his work include the 1844 St. George’s Anglican Church-on-the-Hill; the 1851 Peter Shaver home “Applewood” on The West Mall; William Gamble’s 1849 grist mill on the Humber River at Bloor (“The Old Mill”); and many buildings that still stand in Weston.The Moore house is a simple 3-bay Georgian farmhouse of 1 ½ storeys made of brick laid in a Flemish-bond pattern, now painted white. 

The brick is a light grey colour and was kilned on the property. The eaves have prominent cornice returns at each corner of the house, each  embellished with a quartet of decorative wood modillions.  The front cornice is decorated with nine pairs of small, curved modillions.  The house retains its original eight-panelled front door in a double cross pattern, topped by a transom window of multi-coloured glass. The front door is flanked by tall sash windows with panes of glass in a 12 over 12 pattern.  Original wooden window frames rest on lug sills and are topped with shallow radiating brick arches. A kitchen at the rear was added later in the 19th century and is made of red brick with a contrasting yellow brick radiating arch over the entry door.
