Houzz is the new way to design your home.
Desk in the Lantana study could be angled to face both the window and french doors. I also like the book case above the filing cabinets and love the ceiling design and window trim.
Build in book case needs to be stained wood. However, I like the bookcase up with cabinets below to include multiple file cabinets. Could use shelving for home intertainment system components.
I like the shelving above filing on both sides of the window and the wains coated walls to match the lower level of the bookcase.
Double desk facing the wall option
His & Hers desk, one facing out the windows
A bit much, but I like everything about this study
Rounded book case
