Alfredson's Joinery, Heritage-listed joinery workshop in Cooran, Australia.

Alfredson's Joinery is a heritage workshop complex located at 28 King Street in Cooran, comprising several buildings with varied roof designs. The structures are arranged across a sloping site, with gabled, sawtooth, and skillion roofs covering different work areas.

Mervyn Alfredson, born in Nambour in 1912, bought 950 m² opposite Cooran railway station in May 1933 and set up a woodworking shop. In 1944 he formed M.W. Alfredson & Company and bought the Widgee sawmill near Gympie to supply timber. From the early 1950s, with Queensland Pastoral Supplies, he made pre-cut morticed-and-tenoned house frames, bundled and stencilled, despatched by rail from Cooran.

Mervyn Alfredson, born in Nambour in 1912, trained as a cabinetmaker with Page Furnishers in Pomona and completed his apprenticeship in Gympie. He set up his woodworking shop in Cooran in 1933, and the business remained in the Alfredson family, with the house at 7 Henry Street occupied by the family from about 1938.

The complex sits on a sloping site at 28 King Street, opposite the former Cooran railway station, with the joinery at the front and the pre-cut house workshop and sawmill extending south. The multi-level timber buildings have steps and uneven ground between sections. The site is a heritage-listed former workplace, so check access arrangements before visiting.

Mervyn Alfredson devised the pre-cut system in the early 1950s from ideas he read in journals, working with Queensland Pastoral Supplies, whose mail-order catalogues reached country customers. Bundles were stencilled for assembly and railed from Cooran station with plans, mouldings, doors, windows, hardware and roofing.
