Hello - this is a lovely home! (I keep coming back to it in my Houzz.com perusings :-) I have several questions: 1) Would you mind sharing what type of flooring this is? ... and in the kitchen and entry hall? Are the 'slabs' very large porcelain tiles, or are they sections of poured cement? Also - would you mind sharing who is the manufacturer and installer of these? 2) Would love to know what window manufacturer was chosen for this project. I see there are wooden AND aluminum and/or vinyl (?) windows. If you would be so kind as to share the brand, I would be appreciative. Kind thanks! Ruth
