Let me get into the motivations!
"I had just be challenged by my son and two daughters (one is a Lawyer and the younger she is an an Architect).
They blame me about decisions that have taken place in September 2013 - by the four of us, with a contractor for refurbishing  my 1980 (36 years age) house. They blame my psychological status for: first of all by a decision I had taken about to have a 24 square meters on top of the concrete slab - an extra room, a toilet and a veranda and also about  the huge gap between the amount of payments I have been charged for and the rhythm that the tasks were never get to an end and those that have not yet being performed! Or either were not performed accordingly to the previewed time-scheduled. 

That has turned out in a huge disruption on my life: mainly because I had to move out from my home and go to live with a old couple, who are volunteers of a ONG. Then there was a cousin's apartment free in between rental decisions and selling phase, where I also was able to move in for a month. 
This man had been hired and turned into a nightmare. 

 

For the following  couple of months I had to moved in to by son-in-law and daughter's summer apartment which was temporarily empty. 
Meanwhile I could afford to buy the needed  materials to all works to be finished up. The porcelain tiles, WC and all new taps and sinks that remain stored on site. Although no room got ready for beeing occupied - a   slow motion works are still to be carried on. 
The situation has been caused by an excessive trust and confidence on not reliable contractor.  
We have signed a very poor of detailed obligations for both parts. Actually it was due to a written  agreement that has been formally set with a contractor.

The error had been not only the written accord that does not refer to the timing but also the lack of knowledge I have about the sequence of rebuilding works needed.
This man is an Architect. The contractor himself as a senior Architect appeared to be a solution. who has proved to have a small contraction entrepreneur - which he was not willing to take the us as clients of his business ARCO _(architecture & construction works) . He had promised us that will get prices higher.
This arrangement has been set as soon as he had been refereed to us by a junior close friend of my daughter.
  I have payed for some structural and refurbishing works needed at my house - built 30 years ago. Unfortunately the works were poorly planned. Therefore the payments and the rhythm at construction site got far apart. To set a new contractor I have written a more specif chronometer for the installments to be paid. Again... the same problem. Too little work done for the payments. Exceeded budget has been the reality I had faced.
Last year (2017)  I was able to suspend the Architect technical responsability signed in the licensed for remodelling my house and I hired a second contractor.
