Bring the window down to meet the cupboard. Really lefty47 was right about not drawing attention to it. It is a source of light ,,, so no need to clutter it up. But if you took the colour out and painted the top of the cupbard to match the wall it ceases to draw attention to itself. Just because it is a horizontal space does not meant it needs something put on it. Note- With the cupboard being white, it also draws attention to itself … perhaps take that to the wall colour too and lift the pendant a smidge. So your pendant is the feature there. The cupboard … do yo need it? One way to remove what you are calling dead space is to get rid of the cupboard.

My ex-husband and I had an issue with a large window that looked out over a sidewalk where people were constantly walking by and looking directly into our living room. We solved the problem by using window film that was one-way so we could see out but it was like a mirror if anyone tried to look in. There are other varieties as well. We still got all the sunshine and light but didn't need to worry about whether or not the neighbors could see me watching tv in my nightie on a sick day...It also meant the door to door salesmen couldn't look in and see that I was home when I didn't answer the door. http://www.gilafilms.com/en/privacy-window-film.aspx#.VOuUBS5vksQ

value to you or value when you put your house on the market? it depends on the project. yes, a well maintained driveway and tidy yard will *help* sell a property. elaborate/hard to maintain landscaping won't. many people actually will think 'wow that will take forever/cost a fortune to keep looking like that.' i think more people want easy care as their first priority, and wont pay any extra for an overdone yard. so these days, i'd go all minimalist for resale value. small grass area with automatic sprinklers in areas where expected rainfall will support it, more stone mulch and low water plants in areas that are dry. ticks are a problem and mosquitos as well, so a wildflower border needs to have a defined edge with grass/stone before sitting areas. the nice night lighting no one will ever see when you are selling your house unless its the sort that has its photos taken at night with all the lights on. we've just overhauled our pool area at our vacation home; our theory there is that we want the house to be at all times 100% ready to put up for sale when the day comes that its not fun to own any more. so that $25K won't improve the value of the home, it will keep the home saleable. and we'll get to enjoy it til then.

I think the most impact would come from a well placed, well sized Acer. You can get them grown fairly tall already, Tamata have them and I'm sure there are other places. I'd get one that grows to no more than 3 metres (although check this against your property as scale is hard to gauge from photo), and has changing colours of leaves/bark. I'd place it towards the left of the property, looking at it. That will give some balance to the windows, provide some privacy but not obscure light. It wouldn't be a cheap option but cheaper than painting the house, and would need almost no aftercare. Then some easy care phormiums in the border underneath the windows. Both phormiums and acers come in a range of colours- limes, bronze, purples, oranges, dark reds etc, so choose what you like. The acers are soft and provide movement and variety, the phormiums sharp and provide solid consistent structure. This echoes the plants that can be seen already behind and at the side of the house and should make the hour 'sit within' its environment instead of bing perched on top of it. Also, the edge of the driveway- I would dig a border to just beyond the seam of the gate, lay down a weed mat, and put some stones in there. The garden centre has a range of them, in several colours from white through green red greys and blacks. If you chose reddish (or reddish and lime/orange) tones for your acer/phormiums, I would prob buy a large specimen plant in a pot for the top of the driveway, at the eight hand side of the garage, to link the colours. And maybe paint the front door and have some pot plants there that tone in too, especially in the area near the path that can be seen from the street. For a cleaner line I'd consider painting the lower part of the decking (the vertical frontage) to tone in with your house.
