I typed this up for your other thread but it got locked, so here you go.
Gap years are meant to ready yourself for what you want from your future.
Try using it to research architecture and decide if that's what you want. Go get tours of buildings and see parks that are famous for their design. Take photos of everything to show you used your year well.
If you're staying in the same area, before you dump your life into a big 4 year college, maybe consider taking a community college course on architecture, get some hands on learning experience to figure out if that's the direction you want to go in, with very little cost.
You could even try something on coursera for free.

figure out if you really are interested in that as a field outside of it being one of the few options in your high school career that were available to you. Make sure you care enough about it before you dive in, you know?
If you decide you're dead set on college, you can go straight to it and take the SATs and all that and see how you do, see what your options are. Give yourself the opportunity, and then focus on getting credits in core classes your first year while you figure this out, so you aren't a year behind everyone else. You can always change your major or figure out what you want after you've started, if you're certain college is for you.
Basically, you have some choices to make. A school guidance counselor could help you but I imagine a lot of them are old fashioned and will push you towards college because that's kind of their job, but that doesn't mean they won't also have good insights for you aside from their agenda.
