Q: "Seriously need some help with what to do on this wall..."
A: Great cabinet piece below the tv! The proposed millwork design options are based on the existing cabinet so that everything would mesh well together.
- The cabinet reminds me of a modern farmhouse/industrial aesthetic. You could add a few stacked shelves on one side of the tv or one wide shelf above the tv. Please see examples of a metal finish or painted MDF finish to coordinate with the hardware detail on your tv unit.
- You could use metal brackets to tie in the base cabinet design. I have had custom cost effective shelves made by a local millwork shop and added brackets that I purchased from Restoration hardware, Ikea etc. Shelves can alternatively be purchased from Ikea, Cb2, West Elm, etc and paired with these brackets.
- Alternatively these retailers also sell shelving that you can mix and match with brackets or hardware. Other options would be for an art or accessory ledge wall design (refer to photo) Tv mounting height is ideally eye level when you are sitting. I would adjust the height if required prior to mounting shelving beside or above. Please let me know if you would like supplier information on any of the included items.
