Front extension?!

Hi all🙋🏻‍♀️

I'm just wondering if anyone has ever heard of a front extension before? I don't want to lose out on garden space, as we have a relatively small garden as is, so wouldn't want a rear extension. We don't have any space either side either. Because our house has an unlevel front, I am questioning if it'd be possible to make if all straight at the front so that we gain space without eating into the garden??

Not sure if anyone could offer any advice?

This is what it looks like now (not our house and found on Google):

Extended at front to look like this so we gain living room space as it'd be level with garage:
