Putting a map at the right of blog posts

Site URL: https://feelgoodsociety.fr/adresses

Hello

I have created a guide using a Blog page. As you will see on the URL, each "place" has its own blog post. I also added a map to localize the places, in the intro box (only place where i could add a map) and some filters at the top of the Blog box. Thus map and filters are "not in the same box."

However it's not great in terms of UX. Right now I have map at the top, filters below, and then blog posts at the bottom. I would like to have my filters at the top and blog posts aligned with the map below - posts on the left, map on the right (like classpass UX - cf screenshot). 

I have tried to take out filters from the blog post but it didn't work. I have tried to create a map outside the intro box. Didn't work either...

Does someone know how I can do that? 

Thanks a lot for your help. 🙏
