You can't do it. You need to create an account.
You can build anything on ROBLOX, BC is for upgrades, like more active games, daily robux, and BC games, etc.
There are several million Roblox accounts, however it is impossible to know exactly how many members there are. This is because of two reasons, first off there are constantly new members that are joining every minute. Secondly, there are many alts of other accounts, so the true number of people that play Roblox is unknown.
Builders Club is a premium Roblox feature that allows users to do things such as sell clothes and other items, as well as build up to 10 places instead of just one. There are also other benefits such as the fact that you don't see external advertisements on the Roblox website when you subscribe to Builders Club.
You don't make it, ROBLOX makes it itself, then you can build on it.
