Build hives yourself? Buy it all? or Mix home work with comercial products? edit: open source CNC beehive file site https://www.osbeehives.com/ I found after posting (picture is a yard bee)

My bee journey will not start till next year(signed up for two queens and 2kg of bees), which is meh but also will give me time to prep the area and build/buy proper equitment. I just wanted to ask for input from anyone with experince in bee keeping and being... not flush with cash. As the title indicates I am somewhat handy at woodworking, I was wondering if it is worth/advized building my own hives from scatch. I enjoy the idea of having a veiwing port in the hive that can be covered when I am done creeping on the colony activity. I am sure I am not the first to build their own colony, links to good build guilds would be wonderful too.

Ps. Am I the only one who finds the measurement of worker bees weirdly hilarious, buying 1kg of bees at a time haha
