Well, congratulations!
That said, I presume that your business has risen to the level where it is making enough money to pay the monthly rent of having a commercial space, or that you intend to invest enough effort to create inventory to run a retail operation.
I can certainly see the advantages of having the shop at a different location from the house, the reduction in distractions would be tremendous and allow one to focus more on just printing. I guess the thing I would go for is a storefront shop with living quarters upstairs.
One problem I can see, that I’ve noticed with a local letterpress retail shop: the inability to get work done because customers are always coming in and need to be taken care of. You either will have short retail hours, or a second person to field the customers–or print at night.
