Properly planning an insect hotel - tips wanted

Hello dear garden friends,
last year I spent time preparing a poor meadow. About 40m² all dug up, edging stones set and mixed with sand. Now an insect hotel is to be placed in the middle. Unfortunately, I have no idea about this yet. There are supposed to be ready-made hotels that are completely wrongly built and therefore not accepted.

Has anyone of you dealt with something like this before and can give tips? Or are there websites where you can get particularly good information?

So I am just starting and wonder, for example:
- what is the best orientation to the sun?
- should I plan separately for each insect (e.g. bee room, beetle room, lacewing room, etc.)?
- can wild bees be combined with others at all? Or do some always need to get their own "home"?
- Where can I order "building materials" cheaply?

I am grateful for any advice!

Hello Katja, great idea!!! Hopefully you will succeed well! I myself have an orchard meadow in the forest. There I have a bee hotel, exclusively for wild bees because of the matter of pollination. I bought the first 200 bees and now it runs on its own. The hotel is located directly on the south side, but shaded by trees. The opening faces east so that no driving rain can come in. I bought the largest hotel I could get and supplemented it myself. The building material for me is exclusively untreated wood (I took a piece of a roof beam) with 8mm tubes inside. For you, pine cones, bundles of reed stems, but also bricks with holes would be suitable. Most conservationists also offer construction instructions here. I’m keeping my fingers crossed …

I think the idea is great! Have you ever checked with Nabu for instructions/tips? They have quite a lot of information online and I think this information is probably not the worst. So far, we have only drilled multiple holes in two thick pieces of bark and hung them in a tree or on the shed. The things were inhabited after a few weeks

I hope you keep us updated

That exact spot was what I meant, I just didn't dare to mention the name. Great tip!

Nabu has, if I remember correctly, construction manuals and finished hotels.

You should be able to get most things at the hardware store

I haven't found anything at Nabu so far. Just small stuff. The website is somehow confusing. The shop has no categories at all. ops:
