As chookchook said in her recommendation about painting, put a drop cloth on the floor. Get a very safe ladder. remove the lightbulbs, and cover the outlets. Turn off the electricity to the chandelier. Then spray it with a mild cleaner (I use one I found at Target that's basically water with vinegar, until it's dripping wet. Start at the bottom and work your way up, so you don't have dirty spray dripping on the bottom of the chandelier.Work your way up and down until the dripping spray is clean. The chandelier may be gorgeous and expensive, but it seems totally out of place in the architecture of the room--more at home in a chalet than a sunny room with a window wall. I would probably try to find a way to get it removed, and sell it to someone who appreciated it better than I.

There are some great comment here, but my take on this would be if you are going custom to take your time and look around. Many designers offer different takes on each person's preference. The colours you have are good but I'd personally would opt for a more warmer cream, with a self print pattern. I would also suggest pinch pleated curtains and not pencil pleat as you have currently, pinch pleated curtains will give you uniformed pleats from top to bottom. In addition to this I would suggest you use blackout linen to prevent light to enter the room, and possibly interlining so that you retain some thermal properties in your fixtures. Having custom made curtains are a lifetime choice for most customers, take your time and don't settle for the first company you come across. The space above your bed i would possibly add a sheer fabric roman blind which is slightly see through but enough to give you privacy if you bedroom is situated on the ground floor. You can also get the a roman blind to match your new curtains if you'd like a more repetitive theme in your bedroom. I would suggest if you do opt for a roman blind, and you are looking for a good qualities add blackout linen. If you would like a rough estimation on what you would be looking at we can assist you so you are aware of what most reputable curtain making specialist charge in this current market.

Well that is an interesting picture. I can assure you that hanging wall gardens are all the rage and that is a great idea but they can also be high maintenance if exposed to high winds / sunshine etc. I have seen some lovely fake ones that would do just as well. You could also have a few pots with additional greenery. As you say your view is not "great" maybe you can have a creeper in one of the pots that can weave its way through the railing. I probably wouldn't go for one big chair as it could dominate the entire space. I would consider a table with a couple of fold-able chairs .... something that is comfortable, inviting if you have friends over but can be placed in a corner if you just want to open up the space. I do not think you need a carpet and but maybe some fancy outdoor tiles will look just as nice. You want it to be easy care and weather proof. Do you need or wish to incorporate a washing line? A pull out one from a wall will be perfect that way you can retract it back when you are not using it. If you deck gets too much sun, you may want to consider some shade shutters. I have seen them called 'plantation' shutters. GOOD LUCK

I'm no architect, but I agree with yours. Instead of large windows in the loft above the garage, what about a high, short, but long window....non opening? Here's some examples
