We like designing custom made joinery, as it allows us to create something bespoke for our Clients. Our favourite combination for a TV unit would include some storage below and shelves above. This design allows for both: loads of hidden storage and also space for display. Some nice floating shelves could also create a great atmospheric space for your TV area. Basically, the TV unit can be anything, but our advice is to try and design it in a practical way, allowing space for some storage, of course.
