I bought a greenhouse that has three walls - i.e., one wall is missing. Instead of placing the greenhouse against the house facade, I plan to build a fence/wall in the garden and attach the greenhouse to it.
How would you build this fence/wall? The length of the house is about 4 meters, so the fence/wall needs to be the same.
How would you construct it at the bottom? I'm considering placing a beam at the bottom and then setting posts in the corners to anchor it, and also placing regular slabs along the bottom edge for the greenhouse to rest against. Or are there any other suggestions?
It only gets humid in a greenhouse if you use it like the professional growers do. Lots of plants and watering over everything every day. In a more normally (?) used greenhouse by homeowners, with a few pots and a seating area perhaps, humidity is not a problem at all.

That may very well be the case.
However, I thought it would look nicer to have it out in the garden and not connected to the actual house.
Regardless of the material used to build the wall, a heavy/massive construction is advantageous. It serves both as support/stiffening for the greenhouse and as an equalizing heat storage, as well as an anchor in storms.
Small greenhouses often suffer from rapid/drastic temperature fluctuations. Therefore, a heavy wall is good.
A stone wall is never wrong, but a plank wall also works.

Let's say I want to build a wall with Leca. How do you go about making it stable? The height will be 2,4 meters high, and the idea is to cast a foundation on which the greenhouse will be placed. Also, what dimension of Leca is preferable at this height?
I'm currently building a foundation for a greenhouse. However, it's a slightly larger greenhouse, 16.5 x 16.5 m and about 9 m high We are casting a footing around it at 1.7 m x 0.3 m, concrete footings of 50x50 cm for the loads from the 6 greenhouse beams, leca in between. 2 km of rebar One leca wall will be almost 3 m high since it is one floor lower than the rest.
You probably don't need equally strong structures but a footing about a meter wide and 20-30 cm high, 10-12 rebars of 12 mm at two levels. On that, you build with leca. We use 29 x 19 x 59 leca with reinforcement in every layer, full joint masonry.
Buttresses and additional walls provide side support, I think you need support for stretches longer than about 7 meters. However, we have quite a lot of ground pressure to account for that you might not have, so our design is based on that.
It might be good to let a constructor/structural engineer calculate and design a bit so it turns out well and lasts a long time.
Fun to build with masonry by the way, you get strong with 29 leca
I'm not a big expert at masonry, but I think it will be fun to try. What I'm most unsure about is the foundation itself.
I want a footing where the three walls will stand and a 2.4 meter high wall against which the greenhouse is assembled.
According to Finja, you can build a wall that's 2.4 meters high using 29-leca and at the bottom, their u-block without pouring a proper footing.
Does this sound reasonable for a greenhouse wall? The wall itself probably won't be loaded more than if it were just a wall since the greenhouse will have more anchor points in the foundation.
