It is the "Elena" sofa from Italdivani, a company in Montreal, Quebec. You can customize the material. I purchased it in a small shop in Yaletown, Vancouver, and it was shipped from Italdivani in Montreal.

Love this space. Can you please share the wall color?

All walls in the main living areas of this house, including this children's library, are half strength "Old Prarie" by Benjamin Moore, OC42. Trim is cloud white, Benjamin Moore, CC-40. The house was built over 5 years ago, and is Canada, so not sure if you can find a match to these. I originally chose this Color in a previous house of ours because I liked the Color of drywall when it was raw! That house was my 3rd using that Color, although I think at our farmhouse, I may even have used quarter strength Old Prarie. I like light and plain coloured walls so I can breathe! The painting company was Copper Britsle in Vancouver.

can you tell who is the window supplier
