On the Project, modernism is prefront according to you desire. Furnitures are almost designed by brands that you preferred. For kitchen , design was thought matching with living room and connected dining part to kitchen to close conversationJ l left White between upper cupboard and counter so you can keep White as a colour or you can do acrilic material.(corian, samsung , lg or other brands) On the other hand , you can do 3d wallpaper or artificial material for tv unit. As you want comfortable sofa, it is better sectional ( L corner) for more modern& contemporary spaces.
