Buy a Greenhouse – Quality from the Experts
When you want to buy a greenhouse, you often have many questions at the beginning. It's good to know that you will be properly advised. Just like at Hoklartherm, because our goal is the perfect greenhouse for you! Whether you're looking for a traditional greenhouse, a balcony greenhouse, or a raised bed kit, whether it's a large or mini greenhouse, for growing vegetables, exotic ornamental plants, or even as a living space – we reliably fulfill your greenhouse dreams. We distinguish ourselves from other greenhouse manufacturers not only by the wide variety of greenhouses you can purchase from us. Our quality is also unparalleled. This can be seen in many small and large details, such as the fact that all our greenhouses come without unsightly cross braces in the glazing fields, or our principle that a greenhouse must also have spare parts and upgrade options. Our artisanal operation has grown with greenhouses for vegetables – over 40 years of experience flow into our products and form the basis for your personalized consultation.
And what does a greenhouse cost? Well, that naturally depends on the model and the features. Don't be misled when you compare greenhouse purchase offers. The decisive factor for the price of a greenhouse is not the square footage, but the volume of space. So, also compare the wall height and the ridge height. Equally important are the type of glazing and the weight of the aluminum (the thickness of the profiles): The more stable the aluminum base construction, the more resistant to twisting and thus safer the greenhouse stands. Good to know: With us, you can rely on the highest quality of all materials and constructions – that's why Hoklartherm offers a 10-year guarantee on twin-wall sheets and a 25-year guarantee on profiles and constructions. By the way, with us, anthracite or fir green aluminum profile coatings are standardly included in the price of many models: this is also a criterion when comparing greenhouse prices because many manufacturers generally calculate with plain "natural aluminum." If you prefer a coated structure, you'll have to pay extra. Therefore, it is worth multiple times to buy reliable greenhouse quality.

Stable and Winterproof Greenhouse: Aluminum or Wood?
Not only does the glazing have to meet high standards, but the greenhouse structure itself must also be stable and durable, winterproof, storm-resistant—and not too bulky, as it should not block light. The structure must effortlessly handle temperature differences of up to 50°C between the inside and outside, as well as high humidity (both from inside and outside). Moreover, it must be as well-insulated as possible, just like the glazing.
So, which material should be used for the greenhouse?
The two most important materials for greenhouse structures are wood and aluminum. To give you our conclusion up front: At Hoklartherm, we rely on high-quality and stable aluminum for many reasons—but we don't want to withhold from you the pros and cons of using wood.

Living in a Greenhouse: The Greenhouse Conservatory
There are wonderful ways to experience "living in a greenhouse." For example, you can use the greenhouse entirely as a conservatory, essentially as an additional room for your home. This is possible with our popular, freestanding residential greenhouse "Livingten" for DIY enthusiasts. With its comfortable standing wall height and clear real glass glazing without cross braces, it creates a pleasant sense of space filled with natural freedom while still being protected. If you prefer living amidst your beloved plants, combine a greenhouse and a conservatory!
Ideal for realizing this second option are greenhouses with smart space distribution, like our old English greenhouse York TH. This excellently insulated greenhouse features a bay window that can be used as a small sitting area in front of a dedicated greenhouse zone – or simply as a practical extension of the garden shed. Naturally, the living and plant areas do not have to be strictly separated: How about a garden sofa for relaxing or two lounge chairs directly under palm trees? We are happy to help you realize your best ideas.
Greenhouse: Build It Yourself or Have It Built?
Do you want to build your greenhouse yourself? At Hoklartherm, you're in the right place for a DIY greenhouse – as long as it’s not made from old windows or wood! We can supply you with nearly all of our greenhouse models as kits: from a small DIY tomato greenhouse to the large Arcus L arch greenhouse. With our well-thought-out modular systems, the construction is straightforward, shading is no problem, and we even provide instructions for building the greenhouse foundation. (That is, if a foundation is necessary at all, as our engineers have also devised clever greenhouse solutions that can do without a concrete foundation.)
