This estate has the same kitchen interiors as Casa 01, including same windows as well. Like always some added custom patterns as well, which I do not remember where I downloaded from. I use most of this custom contents to my estates. But all estates are mostly of maxis own content.
I have used a few patterns that I have downloaded, but most of them i do not remember from where anymore since it was a few years back. The Kitchen Interrior is by ShinoKCR from The Sims Resource. The Bungalow window used in this estate is made by Muske at the sims resource where you also can download it.. All credits goes to the pattern designer and to the other designers that had made the few custom content i use to my houses..
