    So we are having an extension on the back of the house and at the same time conveying the garage to my man cave cinema room.

    Here is the garage as it is now just been cleared out of almost all junk ready for the to take off the garage door this afternoon and start the bricking up process.

    Bought a Denon X4400H last week but am currently unsure as to have 5.1.4 or 7.1.2 (with added bonus of adding a stereo amp for 7.1.4), as not sure if the room is big enough.
    We are shortening it a bit as building a small utility room at one end because the boiler is there and don’t want that in the cinema ruining the aesthetics!

    Thought so, it's incorrectly installed just wanted to let you know. you can't use foam to seal the gaps. Because the plastered not been cut tight you need to use a fire batt with graphite wrap.

    Is it a rented property of yours ? Pm me if preferred.

    I own a passive fire protection company and I didn't feel right not telling you that's all pal

    You have good eyes!
    It’s our home not rented, we bought it brand new 3 years ago

    Is it an issue then thats it’s been done like this?
    Should I ask my current builders to have a look at it?

    Was the collar installed when you bought the house?

    It is incorrectly fitted so in the event of a fire it's possible it will not do it's job.
    It does want to be rectified.
    Basically the red fire collar has graphite wrap in side of it, the graphite wrap expands under heat. If the Fire melts the plastic pipe away the graphite closes the hole when the pipe once was. So stops spread of flame and smoke etc.

    A fire collar has 4 lugs normal which are screw into the soffit, but the collars only good when the substrate you are fixing to is tight around the pipe etc. In your case it is not tight and someone has used foam to fill the gaps.

    Foams are only to be used in limited amount of places, but filling a gap around a fire collar is not once of them.

    Are you handy with tools etc?
    Where are you located ? If you close I will do it for you free of charge.
    If not I can send you a tested detail which shows you how to install fire batt and graphite and do it yourself

    If the house is only three years old, I'd be on to the builder or NHBC to sort it. It should have been picked up by their inspector.

    Technically the building shouldn't fit the collar unless there 3rd part accredited to do so like we are.

    But yes you are right it is down to them to rectify if it was fitted from new.

    You should start with a scaled plan of the room - once you have worked out the internal dimensions expected after completion, screen size, furniture placement etc, then you can decide on the speaker layout.

    I believe a minimum of 800mm from listening positions to each speaker is preferred, otherwise you will localise a speaker too easily. Recalling how small my garage conversion became for a playroom, means it may be best for 5.1.2.

    I think the rear speakers are the easiest to lose, and in a small room Top Middle for immersive audio will give you the effects you are looking for. The surrounds can then be just behind the MLP if possible, to help with losing the rears.

    A couple of suggestions.

    1. Put together a realistic budget itemizing the known and unknown costs. Its unlikely to be 100% accurate but it will serve as a guide as work progresses. You will also inevitably incur some extra cost for unforeseen costs as you go along.
    2. Don't be tempted to buy too much kit early on. It is very tempting to get caught up in the excitement but a lot of people who have done their own home cinema find that what they thought they wanted/needed at the beginning changed along the way.
