I understand your concern and advice.

My house was built using a logic that only the outter walls, which are stone on the ground floor and cement block on the top floor, are load bearing.

These will not be touched, besides removing and replacing old mortars.

On the inside, all the walls are for show, made of wood I want to reclaim and a couple that were built in clay bricks but that have no load bearing capability nor structural role.

Drawing the blueprints as the house exists today will serve to have a birds eye view of the house to work on, even with professionals, if the need arises in the future.

This sort of house is not considered interesting for professionals in my area; the structure is too simple and can not accomodate that many changes. And because I'm not rebuilding but just renewing, no projects, licenses or consultancy is required. This makes this kind of job not very appealing.

And thank you for reminding me that electrical and water plants are a thing, aswell.
