The Antique Royal Orangerie has the same dimensions as the Royal Orangerie but leans more heavily into the Victorian aesthetic, featuring glass glazing panels that are narrower than most Janssens models. It looks extremely similar to the Royal EOS T model, though it is a bit larger and its entry foyer a bit taller (as it lacks the roof dip). Like all Janssens models its 4mm tempered glass and 17 gauge aluminum frame make it resilient enough to withstand strong wind gusts and moderate hail. Its doors and windows can be installed nearly anywhere, providing substantial flexibility in design. The primary benefit of the Antique Royal Orangerie over other T-Shaped models is its aesthetic, and it is primarily chosen by gardeners and recreators who want a true antique look.
