To support the longer roof glass panels of this unique glass greenhouse design, the aluminum roof rafter/profiles are twice as thick as our normal profiles. All standard units also include additional triangle cross supports.  The strong frame combines with the 4mm tempered safety glass construction make for a very durable, long lasting structure with little maintenance.  Additional optional triangle supports can be added to further increase the roof strength.

NOTE: M23 roof glass is one long piece per panel, M34/M36 units will have two overlapping panes on the roof, rather than one long piece.  Assembly and delivery is easier and safer due to a more manageable size and weight.

This beautiful greenhouse is highly customizable by special order - size, glazing material, frame color, roof and wall features such as doors, panels, and windows. Call us at 888-648-5333 to arrange a free design session to configure your dream version!

Black is standard, available in other colors by custom order (at extra cost):

8x10 ft (M23), 10x15 ft (M34), and 10x20 ft (M36) are the standard sizes, other sizes are available by custom order (at extra cost and longer shipping turnaround time):

Narrow glass panels (half the width of the standard panels) also available by custom order.

Ground mount is standard.  You can also select that you are building the greenhouse on a 16" or 24" wall (see exact dimensions in the manual) - the glass of the greenhouse wall will be shorter to maintain the same gutter height.  The door will extend to the grade level in a cutout in your wall.  You can also special order for an 8" wall - call 888-648-5333.

If you want to build the greenhouse on top of your wall with the normal full height glass to raise the whole greenhouse up), you will need a drop door kit to lower the door to the grade level, and you will need to provide your own piece of tempered glass to fit above the dropped door.  Be sure to let us know your wall height when ordering this way, so we can be sure the drop door kit is long enough.
