Originally a supplier of milking machinery and tractors, Hastings Diesels Ltd moved from their Melbourne Street premises at South Brisbane to Kerry Road, Archerfield in 1957. The property was transferred in April 1968. Currently named Hastings Deering, the company operates large scale sale and servicing of earthmoving equipment. There have been a few major changes to the Hastings Deering site, including the addition of a single-storeyed administration building to the end of igloo no.2, the construction of additions for such purposes as painting and engine testing, and the re-roofing of the igloos. The site comprises four timber framed igloos with corrugated iron and ribbed metal sheet cladding. Numbered from the eastern end of the site, the igloos are identified by a number from 1 to 4. The site fronts Kerry Road to the north, with a recreation reserve to the south fronting Mortimer Road. All four igloos are of similar construction, and use nailed timber arch construction, where each arm is made up of two half arches pinned at two abutments close to the ground level, and at a central or crown pin. Each half arch consists of two adjacent trusses laced together at top and bottom chord level and each truss consists of a top and bottom chord laced together in arch form. Each truss is therefore made up of four main timber chords sprung into arch form, and light timber bracing nailed into position to form a curved open-latticed box truss. The structures were originally sheeted in corrugated iron, however igloos nos. 1-3 have been re-sheeted with ribbed metal sheeting. The structures also have translucent sheeting at regular intervals, approximately located between each box truss, which provide adequate lighting levels. The igloos have ridge ventilators, concrete floors, and the abutments are fixed by timber plates into concrete footings. Original external stormwater drains along the side of each igloo are still in use, some with grates known as 'Bailey's matting'. Internally, the igloos are used for a range purposes including storage and manufacturing, and consequently have various free-standing structures. Igloo no. 1 is the former store, and is the smallest of the four igloos. It is located closer to Kerry Road than the remaining three igloos which are in alignment facing north-south. When constructed, it was described as being long and span and of Oregon construction, and currently has skillion roofed side annexes.
