The Victorian Greenhouse Collection represents America’s premium line of backyard greenhouse and multi use structures. Made of aircraft grade aluminum and tempered safety glass, these units are built to stand the test of time and maintain their elegant beauty in any climatic condition.

Developed in Belgium where gardening is a way of life, these greenhouses have been refined for over thirty years and are Europe’s Top Class structures due to their rugged construction, attention to detail and classic English conservatory design features including decorative ridge finials.

The 4mm tempered safety glass and rubber sealing system, create a draft free environment and increase warm air retention inside during cold nights and months. The automatic roof window openers allow hot summer air to escape at the appropriate times. The elegant interior shade netting can be drawn open or closed depending on your seasonal or daily needs. In addition, enjoy the overhead misting system to keep your plants fresh at all times. With side walls measuring over six feet in height and the roof extending from there, enjoy the unusual head and shoulder room of each sized unit as they give a relaxed spacious feel, as well as enough height to grow exotic tropical plants and small trees if desired. Also utilize the two long shelves that run the length of the greenhouse. These units even come with gutters and downspouts if you wish to capture the natural rainwater.

The larger units (see all three options) are often used as multi purpose structures. It is not uncommon to see sitting room arrangements in amongst the foliage, and also spas placed at one end to take in the protected tropical possibilities. Another common use is for winter storage of both sensitive plants and outdoor tools and equipment.
