Ours used to have a very similar configuration!
Since converted, we now have 3 beds off a very small half landing and the storage knocked through. You can’t swing a cat outside the bedroom doors though.
I’d buy that if I had the cash. I’d put en suites in the storage and lose the downstairs bathroom. Alas in ours we couldn’t add plumbing upstairs so downstairs bathroom it is (but worth it as we live in a chocolate box thatched haven in a perfect village).
