I got your letter regarding the noise come out from my house at night and how it has been spoiling your evening and causing you some distress.
I shocked when I got it and I am really really sorry for that, since I had no idea that it would be able to hear outside my kitchen.
As you may have guessed, I am trying to refit and redecorate my kitchen by my self as I need more space and renew it. but i couldn't work in the morning because you know my duty time which is start at 9 Am and end late evening. I thank it can be finish within a couple of days, but it took longer than expected, so that has meant a lot of hammering and banging.
Since the kitchen is still not finish, and It's hard for me to work in the day time then I'll call the professional builder to do it, so he would not disturb your night and will finish it as fast as he can.
