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.

A green roof pairs well with gray and white homes. For a subtler look, pair a green roof with a siding in a lighter shade of green. I think you are on the right track .You have chosen harmonious shades . New paint doesn't have to match existing colors, but it should harmonize. Some general tips are- Green roof - Gray, green, or white house colors. You could use a dash of yellow also.

Hi pjfee2...thanks for your ideas. Have to admit I have not given the reno in MT much thought this summer, here!! Actually been finishing our beach house re-build down here and a bit 'reno'd out' to be honest. BUT we head back in just over a month so it’s time I did give it some serious thought, so your comments very much appreciated. Already got builders organized so that’s a start LOL I love the idea of adding stone on the outside to the turret part – but guessing that is as far as the budget would stretch. The siding is in good shape so need to stain it to work. Love the idea of pulling a color from the turret stone to do this. Will get a stone that has some of the log house gingery color in it and then stain the newer part of house a tone of this?? So far I’m sure we will · Rebuild the deck to run across the front of the house and form the roof over the front door entryway · Make the entry way wider and mud room inside bigger · Replace the small window to the bathroom with a door off the deck, matching the French doors. · Replace the tiny window in the turret with a longer one. · Cover turret with schist or stone cladding Not sure about replacing the windows under the deck. Added a picture of them from the inside. This living space is the hardest to figure out how to furnish in this house. It has quite a lot of light from a large window on the left wall - out of this shot - and across the back of the room through a wide door way to the room at the back. Thinking of opening up this wall? And from the inside they seem pretty well balance? Big problem in that room is that there is not a lot of places that we can use to create a sitting area. Need to get a couple of sofas in there and push them around to see what will work. It has 4 doors leading off and as you can see large log posts dotted about!! ANDd a stairwell going down to lower level and garages. Not a lot of space to play with. OK time for another coffee...its 7.30am down here!!
