Personally, I'd prefer a WIR as opposed to a large "wall" of cupboards. I like the ability to open a single door and see all my clothes, rather than opening and closing multiple doors for various bits and pieces (e.g. pants in one cupboard, shirts in another). I think the WIR would be cheaper as nice cabinetry for the second option could be expensive. And I think the WIR would be better for resale value. Also, it's just a personal opinion, but the example photo reminds me of a gym locker room. A nice gym locker room, but that's the impression I have from all the cupboards with the bench in the "middle".

I've realised that the text on the designs may be too small to read or blurred when enlarged so have attached the 5 designs separately. thanks

Both look like nice designs! If you like this style you should check out what Zanda Architectural Hardware has on offer - they've got a great range of modern door handles.

Selling a second-hand door can be quite tricky as not all doors are the same size in width, height and thickness. The market is limited to those who are happy to make a custom frame for it as it is likely that it won't fit into a standard door frame. Despite the craftsmanship I would not expect top dollar, and would let the market decide via auction, such as Ebay. Such a pity as it has so much character, is such a conversation piece, and is not a generic door. Best of luck, Dr Retro of Dr Retro House Calls
