Keep it light otherwise it makes the low ceilings feel even lower. I will share our story in the hope it may help you! Picture 1. We moved from a house with high ceilings to one with low bedroom ceilings and it felt claustrophobic for a while (2 years we put up with it). Our bedroom, when we moved in, had burgundy walls, dark wooden doors into the ensuite and wardrobe, b&w zigzag curtains and pink carpet (yes someone thought pink carpets and burgundy walls would be a good idea!). The one redeeming feature was large glass sliding doors that led out onto a covered deck which provided a view and let in some light (which pretty much got swallowed by all the dark features). We faced our bed towards the doors when we moved in to have a view - as who wants to look into the bathroom like the previous owners did in the picture! Transforming the space: We pulled up the carpet and laid medium coloured wood floors (dark floors were too much for this space and needed to work through entire house), we painted the whole room including the ensuite and bathroom slatted doors white - all of which transformed the space in a way that really surprised me. A tallish wooden bed head and antique dresser, along with tall (rather than wide) artwork help add height to the room as do the doors now that they are white. To keep a feeling of warmth in the room (sorry minimalists out there) I used linen bedding in greys and used blue accessories in rugs and cushions which compliment the artwork which we picked up from a painter on the streets of Paris (framed on our return). We used a muted rug on the floor to bring elements together and for warmth for our feet as we live in a very cool climate during winter months. I simply wanted colour that wouldn't overpower the space. Since pics were taken: We have since started revamping the outside deck and removed some of the lattice which has brought a beautiful flood of natural light flooding in and a view of the garden. Our next step: will be to add some white linen or silk curtains at the highest height possible to maintain an illusion of height. We will extend the curtains to land either side of the doors when open, as while we now need to have them for some added privacy, we still want the light and the view most of the time including when the deck is lit up at night. We will keep the curtains light as colour would encroach on the room size which isn't very big. Our dream addition is to replace the sliding doors with white French doors. Hope this is helpful.

our cavity sliders don't have a track on the floor although the wall needs to be reinforced if you want to mount a towel rail on a wall with a cavity slider inside.. in 35 years we had to replace the fittings on one door (out of five cavity sliders) but you need to make sure that the fittings are good quality but the door will probably be open most of the time and a simple floor mounted door stop installed close to the wall will stop the door hitting anything without being a trip hazzard

think about fencing some hard floored area with a simple baby gate (available on kmart, target, bigW and on line) ...if he has his favourite bed and toys in the temporary goal, combined with strict regular training and walks he will eventually get the message but you must always respond positively when he does and make a restricted space so accidents only happen in a restricted area...i know our dogs are special but they're quite happy in a small space all day as long as they know they can expect your attention and a walk when you arrive home or, weather permitting, a morning walk is even better and they can sleep all day...I was never happy to allow my dog to be left outside alone as they can have injuries (especially if you have tempting rodents to chase) and a special dog like Mace might be tempting to a thief..keep him inside unless you're outside with him

I would recommend a door that goes back into the sides of space. But sorry I can't think what they are called. Maybe retractable? This then allows for space to be completely open without doors or hinges in the way. The only negative is that they do take up extra space when retracted back into sides of cabinet. Having a study desk separate from the bedroom, in my experience is a good idea. The bedroom is for the children to relax and chill, but the study desk is for work and concentration. And when they have finished study for the day, the doors can be closed without having to pack books away.
