Anybody know how to build a bee house?

Hai there! Just wanted to ask for second opinion. Anybody here ever build a bee house before? I am thinking of building one at the back of my house. Read about it. But still a bit confuse. It is advisable to build the house from breathable material. Can I use Bamboo? Or should I use real wood? A little help would be wonderful!

I have not built one so I found some threads on how to build a mason bee house:

Also if you build one you might take picture to qualify for a Badge Bit:

I’m sure there are better native bee experts out there than I and I’d love to hear what they think. I think that the keys are to not use treated wood, use local sourced hollow stemmed plants, make sure that the cavities are as deep as possible, the opposite end needs to be plugged. Then remember that many native bees are ground nesters too, so bare soil that is well drained is important too. https://www.xerces.org/ Has lots of good info.
