are they made of wood or mdf if so. they can be painted

Eric, is it the red colour you don't particularly like? Which timbers do you like most? Have you seen spotted gum? I mention it because the colour tones in spotted gum vary and it might possibly be worth consideration. I realise many consider having the same timber flooring throughout the house as ideal; however, as your bedrooms have doors, I believe it would be perfectly acceptable to have a different timber flooring in them (be consistent here though). If this were my Dilemna, I would match the timber width to the width of your red gum flooring, and use a top-notch installer, someone with whom you can discuss the best way to lay the planks given your other flooring.

Though I don't know for certain, I think the cotton/linen shades are removable. I wasn't able to determine this by my searches. This could easily be confirmed by making an enquiry to supplier before purchase. Alternatively, a handmade one could be made removable by making shade slightly larger than frame and making ties.

I've been playing around with a pantry location. Originally, I was going to move the pantry into the laundry with some custom shelving and cut the laundry space in half. Now, Im thinking of cutting into the study area and building a wall there, and converting the new space into a long and narrow walk in pantry. Either that or build half a wall and put built in shelving in the study. Building the extra wall will reduce the need to cover in the door way that is currently in place and instead utilising it. Thoughts? p.s. this isnt too scale.
