The above examples and 99% of all websites are built the traditional way, the same as constructing a building - put in the foundations, build the framework, add the walls, roof, doors, windows and connect the utilities:- only then can it be decorated and furniture be moved in.
In the real world small businesses don't generally have their own premises built from scratch, they just rent an industrial unit, office, shop, art gallery, restaurant, cafe, workshop or whatever fits their needs. Pay the first months rent and move in.
We have done the same for websites - your next website is already built just waiting for your logo, colour scheme and content.
