Hello. Unfortunately, I’m not an expert in the arrangement of rooms. But my friend is an architect, and he could take a look at this plan. I’ll show him this next week when he comes to my house. But if you still need an urgent response, I’ll send it to him by email if you don’t mind. I’ll take a loan to make such an extension of the house. I’ve already talked about this extension with Mortgage Broker Wigan. My broker said I have a good enough credit history to get a loan without problems. The bank will give me $12k to build such a room on the second floor. Do I need to talk about this with the developer if I’m the apartment’s owner?
