Hi, just moved in to a new place and need some advice on home office set us. We have bought 2 industrial chic pieces from mobilia in rosewood-- a desk, and a bookshelf measuring 60 x 78. Now I'd like to add wall to wall shelving on another wall measuring 148 inches wide x 7 feet high, without having to spend an arm and a leg. It should include drawers and filing cabinet. The grain on the pieces I have exhibit honey brown, dark brown, and a little black coloration. I need help determining what type and color shelving to get ( espresso, white, or brown), where to get it from, and what type of chair to match. I also have some persian rugs I can utilize in the room, or am open to getting something else like cowhide. Would love some ideas!
