The CCTV solution is nice technological fix but why not avoid the inevitable issue of your box gutter failing and redesign the roof? Without having the plans, elevations and levels I would suggest that falling the roof away from the viewer in your image would allow you to collect the roof water on the (western??) side. There are ways to hide a gutter without hiding it inside your building and I personally think that one or two elegantly detailed downpipes can add to the quality of a building, why hide the obvious need to get water off a roof? Also, I would be very surprised if your architect doesn't already have a solution to this, it is a basic requirement of design.

A nice invasive running bamboo would be the ticket to isolation. Where are you worried about it invading - your neighbor? When it invades your gravel areas, you cut out the running root, big deal. If you built a wall, you would have to maintain that, would you not? I am renting a house that is less than ten feet(3 m) from the highway right-of-way, but about another 20'(about 6 m) from the actual roadway, which is about 5' (150cm) above my first floor. As the road curves, it passes both first and second floor bathroom fulll-size windows, yeh. Bamboo to the rescue! We are saved by the lovely self-sustaining bamboo. No fertilizing, no watering, just an occasional clipping of its toenails, each spring. It doesn't soften the sound of the Harley's though. To keep the bamboo from crawling out of its crib, install a galvanized or aluminum edging that goes down 6-12'(15-30 cm) to contain these babies from escape. And let the neighbor go back to Dungeons & Dragons or Sesame Street for their entertainment.

I think it would be a lot of work to achieve a good painted finish. If you can't bear it colour wise, could you sand it and give it a clear varnish or lighter coloured stain, rather than masking it, the grain and simplicity of its construction is quite interesting, especially if it's a cabin. Otherwise you could cover it with a VJ board but it depends what your end look is.

asked B&D and Gliderol .... they said, you can have any colour that you like, as long as its grey! ha! I was thinking maybe a roller door will just look poor when exposed in an outdoor setting (with other beautiful landscaping making it look shabby and out of place) ....looking for a photo to prove me wrong.
