If you love the look, why not. Especially given wallpaper is non permanent. My concern would be the pattern could be distracting when you are watching tv... What type of brick look are you thinking of? The whitewashed look, distressed red brick? The wood wallpapers could bring in industrial look also. Something in the grey tones to tie in with your sheers perhaps? [This article[(https://www.houzz.com.au/magazine/5-ways-to-make-a-flat-screen-tv-blend-in-stsetivw-vs~27012107) may be of interest to you. My brother-in-law runs a online photo slide show on the tv when they aren't watching programs. Beautiful photography from around the world. Much more interesting to look at the the black rectangle.

In my last house, after adding a living room (the area you see this side of the arch) and also updating bathroom etc I couldn't afford to reline the ancient walls in my little lounge (when I removed the purple wallpaper I found a mixmax of boards, gib, pinex, plywood and holes!) so I plastered walls all over with layers and layers of newspaper and wallpaper paste (papier mache), then after applying primer/undercoat I painted with 2 similar colours (rich reds in this case), and stippled the surface with a plastic bag. This made it look just very slightly textured like leather and successfully disguised the uneven surfaces. Gallons of gap filler filled the gaps between the old T&G ceiling boards and evened out the mismatched skirting and scotia. Again white paint on all the trims. Amazing what can be done when you have to make do! This was a great cosy little room! (Before photo is the 3rd one)

Hi there, re the fence my choice would be the same colour as house with either same colour slats or your window surfmist both would look classic, definately NO timber here. Because you are on a corner block I'd be planting a hedge inside the fence with something like Murraya asap, Jim Henson could advise. I would consider Pleaching them up to where the slats start so that you could under plant with something pretty, I'd also consider adding garden lights as per attached photo. plus I would also consider putting "Eye lid" down lights on the exterior posts of the fence, this could add great street appeal for your wonderful very large house (is your whole family moving in. The garage, either same as wall colour or Monument is my choice. cheers,

Before replacing your curtains as this can be quite expensive for such a large window, if they are in good condition, add a band of extra fabric to the bottom in what ever suits you, your existing curtain track can then be moved up to the ceiling for good looking full length curtains without the large round eyelets, could save you a lot of money, I would look at replacing/removing the sheers cheers
