I would put the arch over the slimmest part of your pathway leaving a space between your door and the arch. Moving down then from 7ft wide to a more manageable width. If the archway is too short (bumping peoples heads), you can put planters there and put the archway in the planters to raise it up somewhat. Also makes it easier to grow climbers onto it. Although it may then need anchoring to the roof with slim cables to stop it blowing over.
Perhaps grow a dwarf maple tree to block the sunlight through that huge window. The pencil holly plant is doing nothing useful there in terms of cooling your home.
A few planters around might be nice, also.
Here is a little mock-up. Just for fun.
