    The footstool just makes it more comfortable, I'm quite tall so the recliner part on my legs only comes up to the back of my calfs, the footsool take the weight of my feet. It also means I dont need to recline my chair to put my feet up.

    Screen size is 96", I know I could have gone slightly bigger, but I think this is perfect for my viewing distance and also allows for the girls to sit closer on the bean bags without too much discomfort.

    My screen is built exactly the same as this one http://www.seymourav.com/articles/DIYFixedFrame.pdf

    The only difference is that I have masking that attaches to both the top and bottom to hide the black bars giving me adjustable ratios of 1.81:1 and 2.37:1

    When the masking is attached you cannot tell its not permanently fixed to the main frame.

    The velvet surroundings and masking I still have from my last screen, it is just the main structure that needs building.

    So, 1 day closer to completion and today I managed to give the system a bit of a workout!! Sounding pretty darn good and still got another 8 panels to put in yet, can definitely notice the difference between the left and right walls where one wall has all panels in and one hasn't, slightly less harsh sounding and less tiring.

    Alexa is now controlling everything through harmony which appears to be working really well, although the oldest daughter is already annoying me/Alexa with her constant questions!!

    Screen is hopefully being built and going up tomorrow, if so, first movie will be rogue one as none of the family have seen it apart from me so there choice. Goodies all in already....sweets, popcorn, drinks....would have been cheaper to go to the showcase!!!

    Really pleased with how it is coming on, internally I just need to finish the porch (hopefully tomorrow), screen, panels and cover for the av unit, which will also include a hush box.

    My dad has been working pretty damn hard, he managed to drill through his finger earlier, this was following an accident with the nail gun which managed to go clean through one of his other fingers!! Did he stop? Of course not, just wiped the blood away, stuck some superglue on it and off he went again!!:facepalm:

    It all looks great! The Acoustic panels really set it off nicely. Where did you get the prints on the door?

    Yeah I'm looking poking forward to it all being finished, for three reasons:
    1) getting a bit tiring now, every weekend and most evenings after getting home from work
    2) cost!
    3) after watching 10 minutes of avatar earlier, on a picture projected onto a black wall with ribbed paper, I was 10x more engrossed than on my calibrated zt60 plasma, which although gives an amazing picture, can't give the feeling of a full setup home cinema!!

    Screen has now been assembled and put up, FINALLY got to watch a film and wow, just wow! Picture, sound and experience are all simply stunning. Really really pleased with the almost finished product! :thumbsup:

    Just thought I'd share the build of the screen for anyone interested, as it gives me adjustable ratios for 1.81:1 and 2.37:1 (these were my choices to try and accommodate all various formats)

    As mentioned earlier, we followed these instructions in building the velvet surrounds http://www.seymourav.com/articles/DIYFixedFrame.pdf these I still had from previous
    IMG_3629.JPG

    We now had to build the new frame itself, deciding on using two sheets of 12mm mdf that were biscuit jointed together

    IMG_3628.JPG

    Next magnets were inserted to correspond with the previous black bars that I had which also had magnets fitted
    IMG_3631.JPG
    IMG_3630.JPG

    When the black bars are fitted on the screen they now just magically stay in place
    IMG_3632.JPG

    We then gave it a good sand, stapled the material thoroughly with about 1000 staples, attached the velvet surrounds and hung it on the wall.

    The end result:

    1.81:1

    IMG_3638.JPG

    2.37:1

    IMG_3637.JPG

    Really difficult taking pictures in my room as it is so dark even with all of my lights on, but my screen is completely flawless and looks like a £3000 custom screen now it's on the wall.

    This is what the image is like

    IMG_3635.JPG

    Oh, also got most of the porch finished as well, just carpet tiles to lay and a couple more pictures to go up

    Congratulations! It looks really good! Are you pleased with the seats now that you've used them to watch a film on?

    Thanks mate.

    Yeah the seats are good, I actually had them and the screen from my previous room. Everything else is new.

    Hows the paint now it's been on a few days? People say black paint is difficult to use and marks really easily.

    Yeah it does mark really easily to be honest, but not really a problem in there as it's a dedicated room and won't see much traffic. Would be a nightmare anywhere else in the house though.

    Got a couple of panels up on the ceiling this evening, these ones are plain black, wrapped in a kind of non reflective spandex material. Really surprised how much darker and better for the reflections on the ceiling from the projector they are than just black paint alone.

    Another update, getting a Mitsubishi Zen air con unit fitted soon, my guy is coming over tomorrow to spec out the right one and get it ordered. Should be fully finished soon, once it is, happy to demo the room to anyone who has similar plans or are just generally interested.

    Does your projector produce a lot of heat? I'm planning to buy the same model. Is this why you are planning to install the Air Con?

    All Lamp based Projectors kick out heat, and have a fan - though MB looks to be installing a Hush Box to mitigate the noise.

    The AC will likely be used as much in Heat mode during Winter months, as AC in Summer. It's a an economical & flexible way to heat/cool an "occasionally" occupied outbuilding.

    If heat and noise (fan & AC) are likely to bother you (small room), you can consider mounting the projector in a separate equipment room if building a dedicated cinema room.

    Its not just the projector.

    Obviously we have high ambient temps at the moment anyway, but my room is air tight, meaning I have nowhere for the heat to escape to. If you think about all the items in an AV cabinet, they all produce a fair amount of heat, as done the human body when in an air tight room. My room is also sound proofed and has a number of acoustic panels installed, all of these transfer noise into heat.

    So at the moment, the room starts at a relatively decent ambient temperature and then just gradually rises and rises. An air con unit for me is an absolute necessity. I won't be watching any complete films until it is installed.

    I'm hoping to get by with one of these FRESHBOX 100 ERV (in black)but I know that I will probably end up having to install Air Con too.

    What would you say is the typical starting room temp (say if 20c outside), and what does it rise to after an hour of the kit being on with a few people in the room?

    A lot of Air conditioning units now heat and cool, they are also pretty efficient.

    Personally I wouldn't bother with a freshbox if you are also planning on air con, just go with the air con that can heat.

    They heat rooms really quickly too.....

    My room is cooler than the ambient temperature initially as it is so well insulated. But after 1 hour of viewing the other night, the room temp went up to 26.8 degrees.......that was with 5 in the room though.

    If you have some form of ventilation in your room it isn't such a problem, but as mentioned, mine is completely air tight, the heat has nowhere to escape to.

    An air con unit was always on the agenda for me, so isn't a major surprise. I also have one in my bedroom.....it has been a god send over the past few weeks!

    Well living up north we generally don't get enough warm days to justify the cost of an AC unit, but am a little concerned about my dedicated room. It will still have a window though, but its practically south facing so doesn't help on a warm sunny afternoon / evening!
