Thanks for all the great ideas everyone and sorry I didn't explain the polycarbonate a bit better :) This is along the lines of what we'll be using... http://www.psp.co.nz/building-brands/corrugated-sheeting/suntuf-polycarbonate The area is an absolute sun trap and we're hoping to use it as an extension to our living space, especially on rainy days! I've just sent my husband out to get a few pots of different stains for is to try - darkest brown (cedar) and a lighter brown (rustic oak) both by Cabots + the black we already have. Hopefully we can decide between one of those! I probably should have mentioned we will have black aluminium pool fencing running along the top of the second retaining wall - so the real question is do we keep everything black (pool fencing, horizontal fence, retaining walls and pergola) or do we go with a dark (or even light) brown for the pergola and retaining walls.... We just keep going around in circles at the moment. Decisions, decisions! Thanks again :)

Sorry I am so late coming to your site - you are an inspiration to all, homeowners and advisers alike. For your planting advice, I suggest you call Merrifield Garden Center to see if they will come out your way. They currently have wonderful garden centers in Merrifield and Fairfax (both in Fairfax County) and a new one in Gainesville, but they may come further south to wherever you reside. (www.MerrifieldGardenCenter.com) Even if they don't send designers to your area, they are worth a trip to see their huge selection for a day of pleasure and inspiration, or to pick up some plants. Most of my clients are in the Fairfax and greater Washington area, but I am currently living out west below Front Royal, VA on the Shenandoah mountainside - wonderful views. cascio.offsite@gmail.com

Also take a look at Room and Board....they have several tables with different wood finishes or wood/steel/metal bases and a good selection of various tabletop materials. Also if you prefer a wood table, an area rug underneath the table could also help to break up all of the wood too.

I agree that you should take down the trellis but be aware that you'll probably need to extend your decking rail along that side in order to enclose the deck for building code purposes. If that's more of an expense than you're willing to incur right now, consider at least taking it down to the same height as the rest of your deck and putting a top railing across it. You could then put in some foundation plantings that would climb up and cover the fact that it runs in a different direction than the front of your deck. If I'm looking at it correctly, your gate gives you access to your front door from your drive way. Am I right? In that case, I think your gate should stay where it is. I agree with flair lighting that a new light is in order over your entry. If you like the idea of a motion light, they make decorative outdoor fixtures with motion lights built in. Your fence would definitely look nice painted a lighter color. Right now, as flair said, it's a bit unwelcoming. If you're painting your metal roof, take your house and trim colors from there to coordinate. You could definitely paint your scalloped trim a different color than the house. Matching it to whatever trim color you choose would look great. Do you use the steps from your deck to access your yard? If not, I would consider removing them and closing in that portion of the deck as well. If you do use them, I would add a hand rail for safety purposes. Congratulations on your new house and good luck with your project!
