ᐅ Greenhouse – Which brands are recommended?

About 25 years ago (I can’t say the exact time), my parents bought a structure with a floor area of about 10 m² (107.6 sq ft). It was fitted with 4 mm (0.16 inch) multiwall sheets. These are easy to handle, and if one should break due to some influence, at least there are no sharp shards lying around that could cause injury when picking them up. For that reason, I find these sheets very convenient. However, there is one downside. I cannot say which plastic the sheets are made of, but after some years, small round holes appeared on the outside of the sheets. At first, I thought birds were trying to reach earwigs, which like to retreat into these hollow spaces, and in doing so damaged the sheets. But this was not the case; hail was the cause. Furthermore, the sheets discolor over time, making the interior increasingly darker. I cannot say whether polycarbonate sheets are better, as I do not know what was actually used in that greenhouse.

The foundation for the house was built as follows.

60 x 60 x 10 cm (24 x 24 x 4 inch) paving slabs were used. These were buried about 50 cm (20 inch) deep, so the house now stands approximately 10 cm (4 inch) above ground level. Inside, the aluminum frame of the house was fastened to the stones on the side with galvanized flat iron using anchors.

As ypg already mentioned, there are also foundation frames. Just check the manufacturer websites to see what they recommend for foundations.

Regarding the pond, here are some points to consider.

You should have power available. Depending on what you want to put into the pond, you will need an air pump or even a more or less complex filter system.

Also, please keep in mind that the pond should be deep enough so that it does not freeze completely in winter and leave you with frozen fish. This is recommended if you plan to keep fish; otherwise, you might face a mosquito infestation.

I would always reconsider having a pond with small children around – or are they already old enough?

We have made some progress regarding the greenhouse:
We purchased one with 10mm twin-wall polycarbonate and about 8 square meters (approximately 86 square feet) of floor space.
The foundation frame was included in the September order.
So far, we are at a total cost of around 2,000 euros, which means after extensive online research and gathering information, we chose a larger and better option, making it more expensive.
What I found out: glass is not more expensive than good quality twin-wall polycarbonate, but it does have some drawbacks.
We installed the foundation frame on eight individual concrete footings.
When considering how to design the floor (pathway made of wood or paving slabs, laying or concreting, insulation or not, how to cover the rear area for seating furniture?), it turns out to be like any own work: you need to add another third of the purchase costs to make everything usable.

How is it going with you?

We have done a lot of planting recently and built two garden sheds.
The greenhouse is not set up yet.

Which brand have you chosen now?

It is called Juliana Compact (not a very flowery name, unfortunately)
