Don't you want a place to eat? For me, it would have to start with a dining table & chairs. How large is large? Be sure to get furniture that fits the space. For a narrow area, consider alternating beds at opposite sides of the perimeter. It allows for a wider path and looks less mundane than two stripes of planting flanking a stripe of pathway down the center. My suggestion isn't speaking to whether it's paved, mulched, or even grass. Or how large the bed are. That's something you'd work out in a plan view. We don't have enough information to go beyond basic suggestion. Not to slam the tree, but it's close enough to the fence that is look like maybe it is a weed tree planted by a bird. If so, the chances of it being nice are not great. The lattice looks attached to the fence how one might put on a band-aid. It needs to be in a "picture frame" of wood before being attached. Some post extensions with finials would help the look, too.

Wall paint is your last choice. Do you like the brick? Would you whitewash it or paint it to brighten the room? A thicker mantle hung lower. Yes to paint the brass door. Solar shades on the window and slider. A sofa and 2 chairs to start. Floor lamp for reading some table lamps

Here are a few pictures from the front of our house, we face the west and have an amazing view. We plan on replacing the decking with a composite material in the next few years and then perhaps we can enlarge the deck or add a second level off to the side. We have just moved here from a large century farmhouse with a front porch (wicker and rockers etc), so hence the need for some style advice. Your input is greatly appreciated.

I’d probably do a white base deepish brown trim. Nothing too dark. With light blue accents ( front door. Maybe shutters...)
