Have noticed a need for larger 'static' hab modules while designing interplanetary craft. As those usually use a 3.75m or 5m form factor, some habs that work with that size would be a good addition.

Can use scaled up COS models with adjusted ladder geometry? (at least for prototypes?)

Would really like a new model style for these parts. Something a bit more kerbal, and with windows and airlocks built in. Parts need to be usable both for orbital installations and ground bases.
