There are currently 9 tenants in the building, ... doctors, pharmacy, medical supply store, pedicure, alternative practitioner.... They will do the same with everyone, and no one will accept/rent the standard. As far as I am informed, other tenants will also be getting air conditioning. But it is not necessarily the air conditioning that bothers me about the "AGK". I could even understand that, because it had to be included as a fixed plan in the new building. I am more concerned about the "little things" that can be exchanged without effort. For example, I want different faucets. I discussed this with the installer. He removed the simple short fixtures (at 50 euros) from the offer and put in the desired ones for 120 euros. With 70 euros extra per faucet and 11 washbasins, that is 770 euros! The builder had nothing to do with obtaining the offer, presenting it to me, or anything like that. He only forwards the new offer with 770 euros extra to me and charges nearly 120 euros as "general business costs" for it. Of course, I also pay the 770 euros (which is also self-evident). And this business method generates quite a bit in total!! I am also convinced that these "special extras" are not additional work. The installer does not care which faucet he orders and installs. Nothing has to be relocated or broken open. Everything is still in the shell construction phase. The selection for the "standard versions" was only made after the lease agreement was signed. Then they put terribly ugly standards into the folder and collect money first. The freedom to choose equipment beyond that was promised to me beforehand. That is even stated in the lease agreement, and that I have to bear the additional costs. But nothing about additional costs for AGK is stated! For me, a real outrage!
