If space is needed and especially a good number of bedrooms and bathrooms, then a former bed and breakfast establishment or a hotel for sale might be a property worth considering.
There will be bedrooms aplenty, and surely bathroom and ensuite facilities in abundance, and the site might even be ideal to reopen as a business, convert into apartments subject to planning consent, or invite a good number of family members to make the move with you.
Or if you have a business that needs space but want to live at the site too, then with the appropriate consents in place, a former hotel might be a perfect property to be versatile to suit your needs.
