Beautifully renovated traditional colonial cottage with native plant gardens to the front. The pebbled driveway leads to a gate set in overgrown bushes. The grounds and gardens are extensive and beautiful. No double garage. No 40 Irwin Street is a single storey house constructed in limestone and rendered brick with a hipped corrugated iron roof. It is a fine expression of the Inter-War Bungalow style. The front elevation is symmetrically planned with a central door and hopper light flanked by double hung sash windows. The facade features a full width skillion roofed verandah supported on timber posts. A vertical timber balustrade spans between the posts. The walls are limestone with rendered quoins and sills. The roofscape features a pair of rendered chimneys. There are concrete stairs from the verandah to the garden.
