Much Marcle Garage

Much Marcle Garage is a 20th-century building constructed with a timber frame and clad in corrugated metal. The structure features timber doors, interior partitions, and fittings, as well as timber windows. The main building, which was formerly a hangar, has a simple rectangular shape and measures approximately 73 feet (22.4 meters) by 38 feet (11.5 meters). It is oriented northwest to southeast and has double doors at the front, flanked by small offices. There is also a lean-to extension on the southwest side.

The exterior of the building showcases a segmental arched roof above the central double timber doors, with multi-paned timber windows filling most of the remaining elevation. The rear elevation mirrors this with a segmental-arched roof and features a wide doorway with a sliding door, alongside a multi-paned horizontal window with closely-set timber mullions. Each long side of the building has square, four-paned timber windows. The southwest side includes a small lean-to extension that matches the main building's cladding. The roof is supported by elaborately-scrolled brackets that were originally topped with gas lamps.

Inside, the workshop space occupies most of the building and is characterized by the lattice construction of six Belfast roof trusses, including those at either end. The exterior cladding is attached to exposed timber uprights, three in each bay. The southeastern bay contains a central double doorway, with offices on either side separated from the workshop by partitions that have flat roofs lower than the roof trusses. The office in the southern corner features timber matchboard partitions and a panelled door that opens in two parts. The opposite corner office has internal partitioning originally from a railway carriage, with a sliding door leading to an internal office and a drop-down hatchway installed upside-down. The rooms are fully matchboarded, including the ceilings.
