When you're looking to integrate a contemporary look within a period context, it's important to respect the integrity of the architecture - lighting pieces that marry old and new are the way to go. My favourite pendant in these settings would have to be the Jasper Morrison designed Glo Ball by FLOS. It is a classic piece that will stand the test of time and works well in both contemporary and period spaces. Here is one of my projects that includes the light in a contemporary home- Here is an image I've found (this is a project by NEXUS design), that displays the light in a more traditional setting-

Hi Lorna, it is a lovely space. A big challenge in these rooms is getting comfortable storage because the only walls offering height is the wall you need for the bed. The other walls are too low for you to be able to access storage on them even if you position it there(like under the window seat). So if you need storage/closet space, you might want to consider putting the wardrobe/closeton the far left side next to the bed so that it doesn't close in the room too much and then have a chest of drawers on the right side(1st image), or if that won't give you enough storage you might need to go either side of the bed, in which case, putting shelves behind the bed will project your bed forward out of the recess between the closets(2nd image). Also worth considering a bed without an and so that is one less thing to dodge around(and kick you toe on) in the tighter space. Happy renovating:)

Wow!! You have a great looking house, I would definitely get a landscape architect as Kate suggested, the original planting of conifers etc. is detracting from the look, a modern update using ornamental pears, structural plants would look fabulous, look at Peter Fudge, Jack Merlo, Dean Herald for inspiration, I love the look of your house, could look stunning with the right landscape.

It really does look like a display home, where are your windows? Get some long mirrors and stick those square holders to them so it can help bounce the light around. It also can give it some visual interest because just sticking those holders direct to the wall makes it look extra "display home". Get some good overhead lighting and not just a lightbulb in the ceiling. Add lighting around the room. Tall lamp in corner, table lamp on side table and chunky candles on coffee table.
