You have literally made going out redundant now. You can work from home, and also work out from home. With this setup, you can afford to never see the sunlight again, if you don't want to .Almost 70k on the rack.
Pipe cost: 15k
nuts and bolts: 3k
linear bearings: 3k
steel rods: 10k
powder coating: 4k
rest: on other raw material and labour
Since this was done on my own with no prior experience about material and gym machines, I can confidently say that I've spent some extra amount here and there but that's the perk of diy, you learn something new everyday.
I bought the bench from market for 10k and the 150kg plates for around 22k. Barbell was around 4k and stall mats around 6k. I also spent around 20k on Bullrock adjustable dumbbells but send it back and got refund. So overall cost of the setup comes to ~1.15L.
Just add some shotguns to this rig and you are ready for an (impending?) Zombie apocalypse!
