restoring

Hi, is anyone able to tell me if it is possible to make the front of this house brick please? If so, what would the process be called and if anyone has any budget range estimates that would also be great. Thank you

Bottom of front door has had varnish worn away. The wood seems hard enough but on the fixed threshold bit there are grooves. Can this be filled with filler before painting? Or would appropriate paint be enough after sandpapering? I'm not a DIYer but money is tight at the moment so I'm hoping...
