Freestanding or Attached?

With a spacious site, plenty of sunlight during the cooler months, and access to power and water supplies, a freestanding greenhouse is often the first choice.
And we’ve built many freestanding greenhouses in the Charlotte area, ranging from 8’x8’ to 16’x24’, with rugged, red cedar frames, multi-wall polycarbonate glazing, automated vent windows, and other climate control equipment.
But not every grower in the Charlotte area has the ideal site or the budget for a freestanding greenhouse.
Sometimes, the ideal greenhouse site happens to be right beside an existing structure - like a storage shed or a detached garage. Or even right beside a grower’s residence.
In these cases, an attached greenhouse design is typically the answer, and very often, this is built using a shed roof or lean-to style design.
The biggest advantage to attached greenhouse designs - whether it’s an upscale conservatory attached to your home, or a simple, cedar-framed greenhouse built onto the side of a detached garage - is lower cost, because there are fewer walls to build than in a freestanding greenhouse.
Conservatories, solariums, and sunrooms describe the high-end version of the attached greenhouse concept, and there are companies who specialize in these structures.
One of our favorites is South Carolina-based Florian Greenhouse, who builds and installs elegant, metal-framed conservatories and solariums, with multi-pane, high performance glass glazing, in the Charlotte area.
These high-end, attached greenhouse structures can add value to your home, reduce your heating costs during the winter months, and add welcome humidity to the air inside your home, during the winter.
Conservatories, solariums, and sunrooms offer the convenience of access from inside your home, and these structures often house hot tubs, reading, dining, and entertaining areas - in addition to plants.
And, as you might imagine, these handsome structures usually come with a handsome price tag to match.
At Microfarm, we build space-saving, budget-friendly, lean-to style greenhouses, framed with red cedar, and attached to a side of non-residential buildings, like storage sheds and detached garages.
Just like in our freestanding, cedar-framed greenhouse designs, we use either twin or triple wall polycarbonate to glaze our lean-to greenhouse designs.
We prefer multi wall polycarbonate glazing because it has outstanding insulation value, various options for heat screening and light transmission, and multi wall polycarbonate greenhouse glazing is virtually shatter-proof.
It’s easier for our crew to transport and install than glass. It’s safer for the people using the greenhouse, and much easier to remove and replace, in the rare instance that it ever is damaged.
Our cedar-framed, lean-to greenhouse designs can be fitted with automated vent windows, louvered shutters, exhaust fans, grow lights, cedar potting benches, and raised garden beds - just like our freestanding cedar-framed greenhouse designs.
A single entry door that allows access to the greenhouse from outside the adjacent building is standard, but in some cases, we can cut another door for access to the attached greenhouse from inside the non-residential shed or garage.
And while of our cedar-framed, polycarbonate glazed lean-to greenhouses may not spike the value of your home the way a fancy glass conservatory might, there are some notable advantages to ‘keeping it simple’ with a smaller structure that’s attached to a non-residential building.
Conservatories, solariums and sunrooms that are attached to your home are certainly more convenient, and the warm, humid air is often welcome inside the home in the dead of winter.
But in the summer months, this very same warm, humid air - which is likely to become even more warm, more humid, and also include a variety of winged insects - must be dealt with by sealing off the access door from the sunroom to the home, shading the structure with blinds or shade cloth, investing in low-e and other high-performance, heat-screening glass glazing, applying insecticides, and usually some very, very capable ventilation equipment.
These summer issues that come with with conservatories, sunrooms, and solariums attached to a residence, are usually non-issues with smaller, lean-to greenhouses built onto the side of a a shed or garage.
With these more modest attached greenhouses, it’s generally understood that, while the greenhouse can be used to grow plants most of the year, during the summer months, it will be too hot inside for growing, and the lean-to style greenhouse will serve as more of a storage space for garden tools and supplies.
