Hi Nimas, both are possible and correct. :) You could also say "I had a house built for myself" if you did not build the house yourself (with your own hands, for example), and hired someone to build it for you.

Hi Ramin! "Being" is the present progressive form of "to be." "To be" indicates a state, so something that is ongoing and usually unchanged over time. "Become" indicates an event or action that changes a state. Examples of to be/being: "He wants to be a scientist." "Being the center of attention is never fun." "She likes being in charge of projects." Examples of become: "He became a scientist after he graduated from college." "Once she found out what he did, he became the center of attention." "She became in charge of this project after the old boss quit." I hope this helps!

Hi Cilla! These are some good questions that I even struggle to answer as a native speaker. For ''1888: Jack the Ripper strikes in London - he is never caught,'' I think this may be similar to your second question where you mention the use of présent historique. In this case, "he is never caught" would be correct since he never was caught. Saying "he had never been caught" would imply that he would be caught at some point, which is not historically true (I had to look this up, I didn't know these details, hahaha). Also, I just looked into it and English also has a ''historical present'' verb tense! It just isn't used very often, mainly in books/sometimes when talking about history/sometimes when telling bad jokes.
