Glass Garden Greenhouses
Meet The Cottage: timeless glass architecture, a cozy lounge inside, and garden views in every season.
View All ModelsGlass, polycarbonate or solid wood. Every range is engineered to the same standard, so the only real question is the look and the space you have.
For the ones who want the best seat in the garden. A modern glass room where you have coffee in January and dinner with friends in October — and that makes the whole yard look designed.

For the ones who'd rather eat what they grew. Tomatoes from March to November, picked ten steps from the kitchen, and you know exactly what did — and didn't — go on them.

For the ones who want both. Seed trays on one side, armchairs on the other, in hand-finished wood that looks like it has always stood there.

Living spaces designed to blend elegantly into your everyday life.
Thicker panels, heavier steel, and an arch that sheds wind and snow — here's what that means for your garden, season after season.
Heavy-duty galvanized steel tubing delivers 50% more rigidity than standard aluminum frames, built to handle wind, snow loads, and years of use.
Twin-wall polycarbonate panels are 70% more impact-resistant than single-wall. UV-coated, insulating, and built to stay clear for years.
The arched structure naturally deflects wind and sheds snow. Rated for 65 mph gusts and 32 PSF of snow load, about 3 ft of snow, grow through any season.

Answers to the most common questions before you buy.
No full concrete slab is required on any of our models. The polycarbonate range anchors its arches directly into the ground, with the steel base plate included. The glass and wood ranges sit on a flat, level and stable surface with their anchoring points secured into the ground, concrete footings or pavers. Footings are recommended on exposed or very windy sites.
No specialist skills and no professional installer are needed, but plan a real project rather than an afternoon. Two people and common household tools are enough. Count 1 to 2 days for a polycarbonate greenhouse, 2 to 3 days for The Retreat, The Cottage and The Residence, and 5 to 7 days for the larger Manor and Estate. In the wood range, 1 to 2 days for The Snug and 3 to 5 days for The Lodge and The Homestead. Every part is pre-cut and labeled, with an illustrated manual included.
Yes, and the rating depends on the range. Polycarbonate models are rated for 65 mph winds and 32 PSF of snow load, about 3 ft of snow. Glass models are rated for 115 mph winds and 48 PSF, about 4.5 ft of snow. Wood models are rated for 115 mph winds and 32 PSF, about 3 ft of snow. Twin-wall polycarbonate and tempered safety glass both resist hail without cracking.
Polycarbonate is the practical, high-yield option: about 85% light transmission, strong insulation, the widest range of sizes and the lowest entry price. Glass gives up to 95% light and a permanent architectural presence, for a garden room you live in as much as grow in. Wood combines the two: tempered safety glass on a solid Nordic spruce frame, for a warmer, more traditional structure.
Very little upkeep in every range. Galvanized steel and powder-coated aluminum wipe clean with soapy water and never rust. Polycarbonate panels rinse off easily and tempered glass washes like a window. The only recurring task is on the wood range: one coat of outdoor wood oil per year keeps the wood protected.
Shipping is free and fully insured to the 48 contiguous states, delivered curbside on a pallet by freight carrier. Estimated windows are 4 to 6 weeks for the polycarbonate range, 10 to 12 weeks for the wood range and 14 to 16 weeks for the glass range. Tracking is included and our team is available for any question about your delivery.
The polycarbonate range is modular: it can be extended at any time in 6.6 ft sections using the extension kit, up to about 98 ft of total length. The glass and wood models are fixed structures, so choose your size at the outset.
PrimeGreenhouses sells 13 walk-in backyard greenhouse kits in three materials: twin-wall polycarbonate, tempered glass and solid wood. Every model is a real outdoor greenhouse you can stand and work in, shipped free to the 48 contiguous states with pre-cut, labeled parts and an illustrated manual. Whether you need a small greenhouse for a side yard, a hobby greenhouse for seed starting or a large glass garden room, the whole range is built to the same standard.
Our polycarbonate greenhouses use twin-wall panels in 4 mm or 6 mm on a galvanized steel frame, rated for 65 mph winds and 32 PSF of snow load. Five models, from the 6.6 ft wide Compact to the 9.8 ft wide Timeless hoop house and the Peak gothic arch greenhouse, cover 43 to 388 sq ft and extend later in 6.6 ft sections.
Our glass greenhouses combine 4 mm tempered safety glass with a reinforced aluminum frame, rated for 115 mph winds and 48 PSF of snow load, with a 12-year frame warranty. The range runs from The Retreat, a lean-to greenhouse for a house wall, to The Estate, a 750 sq ft U-shaped orangery.
Our wood greenhouses are built from solid FSC-certified Nordic spruce with 18 mm walls and tempered safety glass, rated for 115 mph winds. From The Snug potting shed to The Homestead garden room, they bring the warmth of a wooden greenhouse to the backyard.
Start with the space you have and how you will use it. To grow vegetables on a budget, a polycarbonate greenhouse kit gives the most growing area for the price and strong insulation. For a greenhouse that doubles as a sunroom or a place to entertain, choose glass. For a traditional look that blends into the garden, choose wood. None of our greenhouses requires a full concrete slab.
