Kudos to you man. In the Phils I don't think I'd want to get into that. I grew up with parents that worked together very well on doing that.
My dad had his own construction company, and on top of all the houses/barns/commercial buildings that he built during the day, he'd come home and be working on out house. Parents always had at least 2 houses and each had their personal address at different houses. Tax reasons behind that. But, I moved at least once a year growing up. Often I wouldn't leave the school district/town we were in, but always moving and moving into half remoded homes that I was the free labor at around age 10 to help remod houses we lived in...sometimes the one owned but not lived in.
I can remod just about any house in the US now. Hated doing it as a kid, but now I never need to hire anyone to do anything on any of my houses, including additions. So NOW i'm happy I was raised the way I was....but what I live in here and see here are nothing like what I worked on growing up. From the electrical, to plumbing to building material and setup. Hell, my first official job was building log homes...I worked a summer before that under the table on the "styrofoam" with column based homes(pretty interesting really, but rarely done, at least in Michigan). So I have a wide experience...but stuff here is crazy off.
So best of luck to you. Be it in form of getting the supplies you need or the people to help you do it. I just shake my head at the crazy electrical systems I see here. I think it would take a month alone just to take an existing house and rewire it to the code that would make me comfortable when it comes to the circuits and being grounded and proper breakers and all.
Took me a week to do our home after I showed up and I was lucky I caught the electrician still working on it an stopped him. Breakers off of breakers off of breakers? What kind of madness is this? Then after you rip it all out and redo it you still need to get out the concrete mix and recover the wires.....
I just don't think I have the patience to go through a full remod of a house here in the Phils that was a complete build by local construction norms. At least not a remod to the level I am comfortable living in.
