I adore both Interia and Lo and Co Interiors for hardware. They aren't cheap but I wouldn't say they are super expensive. If you use some of their statement hardware, you could just do them on lower cabinetry and leave the upper cabinetry as push-to-touch and keep it simple and a bit cheaper.

look on the page where you found them on houzz and you can send a question to the pro!

These are my hand made Spanish tiles. They have the undulating surface which give texture and interest. I think this is what the blue tiles are. Hope you locate the blue tiles, the kitchen will look fantastic. I wish now I had taken more risks with colour, and not listened to my husband.....oh well, maybe our next house....

I think it would depend on location and the number of lights installed. In the kitchen you would need more light then in the Tv room where you would have other type of lighting like floor or table lamps. Maybe post some photos and size of the rooms.
