Hi Kristen -- What a gorgeous space to have, you lucky thing! I can see why you want to make the most of it. Like you, I think the blue rug is...not the best choice. I'd focus on finding a solution that works well for you there, because that could really drive how you want the rest of the room to go. If you fall in love with a bright rug/carpet squares, you may want neutrals elsewhere. And if you stick with a jute/sisal rug (or neutral squares) you may find you crave some color elsewhere. The green is great for a sunroom, though! (IMO, anyway) I'm posting two possible sources of inspiration -- your room would work well as a mash-up of both. #1) Pale (green) rug; chairs I'd want to cushion-up but are great colors (spray painted)? Pretty sure if you did shelving full of plants I would be greener than they are. ;) #2) Dark ceiling; medium-dark natural fiber rug; large white mats around art; lots of white upholstery (I'd definitely avoid the heavy + dark-toned furniture since your room isn't a this big ole one) Whatever you end up with, I'd think about adding small touches of darker-colored items to help tie the wood to what you put in. Could be a print that has deep grey or darker green, could be thin legs of a lovely table like Roarah's....

I go with the sunroom, too, and here's why. You can build a shed for cheap at some point, and until then you'll probably keep one car inthe driveway, and all the bikes and basketballs in the garage along with the yard and snow tools. The sunroom will make a great playroom while the little ones are little. I've seen that sunroom with nothing in it but a low-pile play rug and Lego. Or balls. Or plastic hockey sticks. Or those big Little Tykes (slide, trikes, trains) Or Hot Wheels. Or dollhouses. Or art projects (easy-to-clean tile floor). Usually just one or two of those. But a great playspace, near you but not, outdoors but not. After they are done with those types of toys, it can be dining space and added living space. You don't need the shed until Boy #1 gets a car. Oops, didn't mean to scare ya lol! Upstairs, I wonder if you can steal some space from the game room to make a reach-in closet for Bedroom 2, and use its walk-in closet to expand the bathroom. 5 boys will need more counterspace, more drawer storage, and (I can't believe I'm saying this, I'm usually a 1-sink gal) 2 sinks. Downstairs, consider eliminating the study closet and adding a shower to the powder room.

A phony plant in a sun room makes no sense at all and if you are actually planning on using the space invest in some solar shades and since the space gets so much light I would choose another color instead of yellow.The reason you see so much wicker in sun rooms is that the sun ruins fabric and wood very quickly that is why I say solar shades to keep the view but block heat and UV rays.

Can you create a wide shelf atop/within ) the windowsill of the pass thru window behind the sofa for the fish tank -- extending into the sun room. If so, do -- better for the fish and for the use of the room. You could still put the chest beneath the tank. Would not put a rug in the dogs room unless it is a small washable one b the door intended for wiping feet and for the dog's use. You might consider a "bean bag" chair for your pooch so he doesn't want/need to sit in your people seats. If you do want a rug in your sun room, instead of one rug, consider two (or three counting the wipe your feet rug)-- one a smaller oval or round or square rug and the other rug (matching or similar) a different shape -- a rectangle for the larger part of the porch. Put a faux grass rug or runner on the primary exterior approach to the porch door and add a rug intended for exterior use OUTSIDE the door to catch some of the dirt. Put a small washable non-slip rug by the door from the left side of the door to the wall on the right side (the wall behind the dog house). If you then put the dogs water dish and food dish behind the dog house, the dog will need to walk over that washable entry rug to reach food/water and, hopefully, catch some more dirt/mud before tracking it across the rest of the porch. You might easily refill a water bowl and dry dog food bowl placed behind the dog house from that pass thru window behind the dog house could. Keeping those behind the dog house could prompt the dog to claim that end of the porch for its own and make it a bit less likely to track dirt elsewhere before checking those food/water bowls (and, by doing so, wiping its own feet on its own rug by walking over it).
