Combine two commands for the same line in Linux

I need to execute two commands in the same line from the terminal. But it executed only the first command.

./build.py || cd /ns-3.20

That command only build was working and doesn't navigate to next directory.

Where am I get wrong?

With ./build.py || cd /ns-3.20 you only go to /ns-3.20 when the first command fails.
Is /ns-3.20 a directory you can access and has some files you need for repairing the build?
When you want to go to that directory only after success, use &&. When you want there independant of the result, use ;.
