How come Architecture has no specific requirements?

I expected to see the same thing I saw with Engineering but quite the opposite.
Thoughts? Answers?

You do need a creative course and/or a portfolio of work to apply.

It's a training program of 5 years study and 2 years work placement - that's time to train people from a broad range of backgrounds if they have the right visual skills

That is much longer than I expected. Didn't realise it was 7 years

3 years for a BA/BSc/BArch, 1 year work experience (paid), 2 years for an MArch (funded like undergrad courses are), 1 year paid work experience followed by an exam to qualify

There's other routes and some people don't progress further than the BA but still work within architecture

The majority of people do more than 2 years working "experience" too; for most people the total time to qualify is often nearer to 10 years. Realistically though once you've done you're MArch you're basically done with university and getting paid so its not too bad (it's terrible but still).

The pay isn't good is it?
