Essentially, Glengallan's story is one of boom and decline: The boom years of wealth and standing; the successful pastoralist erecting a suitable ediface for his hard-won station. But before even the homestead was completed, drought and rural downturn would take their toll.

The visionary John Deuchar would die, bankrupt, a broken man. Under later owners, the Slades and Gillespies, Glengallan did again experience good years but never saw its grand plan realised nor even known.

Only one wing was completed. The plans have never been found.

The homestead, incomplete and inadequate, eventually became derelict, seemingly beyond repair and certainly beyond the means of subsequent owners of an ever decreasing acreage.

The once-great Glengallan went into a decline lasting more than 70 years during which furniture and fittings were sold or removed from the building. The house survived event the post-war threat of demolition but the ravages of time and neglect took a dreadful toll.

Even a Federal Government Centerary of Federation grant of $2 million could not totally restore Glengallan. But the project it enabled goes a long way towards telling the story.

Glengallan's past is encapsulated in history. Its future, as a significant attraction of the Queensland Heritage Trails Network, carries the promise of return to glory. As history unfolds, and more evidence and information come to light, the restoration can continue.
