What a nice sunroom. I like the cushion, but the whole thing still seems rather bland on my screen (no views to pick it up). And I've always been a white lover. My "vote" would be for you to choose a color scheme and then paint the wicker a glossy color of your choice. Maybe take a cue from that nice brick floor so that any choices make it look its best. I'm thinking a dark brown or very dark, slightly cool green, but glossy navy sounds wonderful. :) Red? You have so many options, depending on what you like. I think it might help to split up the furniture, though. Maybe put the chairs and ottoman on the end of the porch for a separate seating group, facing each other entirely or angled also back toward the main group, and then bring in chairs of another style to go with the loveseat, turning their backs, at least partly, on the garden (swivels?). All the wicker wouldn't have to be the same exact color. Maybe only the settee in a dark color and the chairs in a lighter version of the same color, or vice versa? The tables could remain to flank the settee, painted the same color, to add importance to that area. But maybe cover the tops with something a little different to add more interest without actually grabbing attention? It could be a different material than glass. Or something attached to the underside of the glass (collages from school papers, antique-style maps, fabric with a great pattern, seed packets relating to the garden, whatever furthered the look you like). Will you need a reading lamp? Floor lamp, or the coffee table could become a side table to hold one. Not right now, maybe, but how about upholstering the top of the coffee table to turn it into another piece to sit on, and in the process break up the expected? Or move it to another part of the porch altogether and set plants on it?

What a pretty room! Do you live there year 'round or is this your summer place? I am in Michigan (GR) and spend a lot of time at the big lake. How many people do you typically entertain, and what kind of entertaining? Dinner? Drinks only? Just hanging out? What is in the armoire? I like the idea to replace the armoire with a chair, or if you frequently have people over for beverages, maybe it could be the drink station. For large gatherings, you could place a table through the middle of the room with chairs on both sides. That is what we do in our sunroom for Thanksgiving and it works out really well. We don't have quite the same view, though!

Get a pro KD and contractor on your site. ASAP. and don't waste time seeking online opinion of which there will be a thousand. ..................and not all will even be feasible. The "layout that makes sense" is one you develop WITH the designer, not a cabinet seller. It is in consideration of all that is on your wish list, and also what is possible within the space. Possible is partly a budget function, load bearing wall function and other things as well. What makes the most sense, is to EXPLORE those possibilities with a pro, ON your site.

A bit confused…the first photo is of the two leather chairs with backs to the new sunroom. The second photo is of a sectional….where is that piece? Would you take a photo of the sunroom itself, and then standing in the opening with your back to the sunroom, take a photo of the family room. I understand the suggestion of transition and that is easy to do. I want to know/see why you have the two leather chairs in that position. Looks like barrier keeping rooms apart.
