The Portico greenhouse is available with two porch configurations. Shown here is the wider of the two accommodating double doors. Such a greenhouse is easily accessed through the porch allowing plenty of space for greenhouse staging and even a table and chairs.

The full length of the main greenhouse ridge together with that of the ridge of the porch are ventilators that operate on wax filled pistons. In the warmer months of the year the wax in these pistons expands pushing the greenhouse vents up and allowing the warm air to exit the greenhouse. As the temperature in the greenhouse cools the wax contracts and the vents close.

The Portico greenhouse is modular in length and is available in several widths. Should you choose to have cold frames you may opt to put them either side of the porch or down the complete length of the greenhouse.
