You have done a beautiful job of tucking plants into the crevices of your retaining walls. Your house trim color is perfect -- just slightly lighter in hue than the retaining wall blocks. First I would paint the big, flat gray wall slightly lighter than the blocks and slightly darker than the house trim. The concrete walk and stairs I would stain a mottled blend of the blocks and the house trim colors. Next would be to paint the railing black or the house body color. Now, think of the following as creating a light, airy trellise structure from the walk-level face of the (currently gray) wall to about 7' above the top of the wall (using 6x6" posts attached to the wall) with a corresponding line of posts sunk into the terrace level 2' in from the outside edge of the wall-attached posts. The inside posts would be about 6-8" higher than the outside posts. Put 4x4" wood to attach the outside line of posts to each other and do the same with the inside line of posts. Run wood pieces at the top of the two lines of posts from the inside line to the outside line at about a 45 degree angle. They would be cantilevered up at the terrace level. Across the top of the angled pieces create your top trellise boards which run parallel to the two lines of posts. OK. There you have your basic structure. You might want to extend the structure around to follow the street side of the terrace. You could then follow the suggestion of reom10 above about creating a bench-planter on the terrace side. Your spacing of the boards parallel to the gray wall and attached to the outside posts would determine how private you wanted your terrace to be. You might want to soften the terrace "floor" by using something irregular like flagstone with groundcover plantings between the stones. From the latticework on top of your structure you could hang seasonal flower baskets. Plant vines to go up the trellis and spill down the wall. How about planting a row of tall, narrow shrubs along the neighbor's fence above your terrace to help add to your privacy and make your yard feel less 'structured'? Or, how about patio table/s with umbrellas to block your neighbor's view? Anyway, you have a fun project ahead of you.

Thank you everyone for your comments. We live outside Christchurch, and the house was badly damaged in the quakes here. The post-quake rebuild process could safely be described as slightly chaotic, and the house company I am using are located some distance away (like on the North Island), which is why discussion with the architect has been - em - less than optimal. The architect threw something at me to get me out of my comfort zone I think and this is what's freaking me out! I think the windows on the east side are to come (no reason for them not being there), and probably a skylight in the kitchen roof. The section of land is narrow and steep, (this is a historic port town and with access from the south (where the view is); there is no parking other than on the street (south). Patricia - the laundry doesn't sit right with me either! Looks a bit like it's been glued on the side of the hosue. And it is too small as it is to store coats, shoes etc. This is the access to the back garden - thus the door (also means muddy boots can be dumped when we come in!). Entering a house through a living room is very common over here, especially where space is at a premium (small section, small house footprint).

Thanks Orangecamera. It's still a work in progress and mud everywhere Sorry we did look at having the steps' off set' but it didn't seem to go with only three steps and a small area. And about the zen well the cats are doing that for us much to our disappointment (it's still like a litter box to them). We went to the garden supply place still not knowing what kind of stones we were getting. We stood in front of all the bins (there where many). We even looked at mixing some. The grey stones had a bin more the size we wanted but we ended up getting the golden fleck. It was a little smaller, which was a shame, the bigger ones were so mixed in their grading it looked too messy. So this is what we finished up with. It was seagardens that got me thinking away from grey and nwduck mentioning the drainage. So this has really helped. Also everyone seem to think the wooden steps needed to go a lot lower. Next it's figuring out where the large river stones should go

So you dont think we need bench top on both sides?
