Hi, I have changed the plan as suggested by CharlieKLP which is a much better, slightly larger space. I guess this would be acceptable to do without BC input as there is a large window with two openings for escape and ventilation. The only thing i'm not sure about is that there is a window on the right wall which I would need to stud/dry wall over, are there any potential issues with this other than if it would need maintenance? Cheers. Update plan.pdf

Cheers, I did think about that when first planning it but before I knew about the issues with inner rooms I thought it would be better without any windows!! Plus the way I have it makes it really simple to build, if I split the room and use the far end for the cinema room it would involve moving some downlights and a radiator, I was a the top end of my budget but I might be able to stretch it. You have got me thinking now and i'll have a look at it again as it would be a better option and better space. Out of interest is it OK to build a stud wall over one of the windows at the far end of the room? Not sure if there would be any issues with this.

I did initially plan it that way but for the projector and screen size I was looking at it made the projector throw distance very tight. I know it is only slightly longer but the projector could go back nearly half a meter. Now i've learnt about the issues with inner rooms if rotated it would still have the same problem as the door to the cinema room would still go into the existing area.

Plan of the house attached, I have pasted the inner room onto it. Thanks for all the replies, seems to be getting a bit complicated and i'm struggling to get any reply from our local BC company. I'm thinking I might change it and make the two new walls half walls (pony walls?) around 1.5m high so its more open plan but I could still use in-wall speakers. Wont get the same level of sound proofing but to be honest I currently don't get too much sound leakage into the rest of the house anyway. I guess this would be OK as there wont be any issues with ventilation and fire regs?

Thanks, I mentioned to building control about installing one of these in the loft above - Vent Axia Positive Input Ventilation Unit along with a couple of small vents in the two of the corners.. Would that work?

Thanks, that is the best explanation i've seen. I might let him get on with the job but just make sure I comply, struggling to get any reply from our local building control.

Thats my concern, the builder who was supposed to start next week was certain it wouldn't need any regs but I bumped into an old friend who works in commercial construction and he thought as its an inner room with no window I may run into problems if we ever sold the house and we hadn't run it past building control. Quick question, i'm very naive to this but when does it become classed as a room, if I didn't put a door on the new area and it was left just as an opening would they still class it as a room?

The existing door is onto the landing, then downstairs to the front door. Cheers.

Hi, I’m looking for a bit of advice regarding a project i’m hoping to get completed, I have contacted our local building control guys to see if this is OK to do but i'm still awaiting their reply. It is a fairly straight forward job with no structural work involved and no change in usage, above our double garage we have a large 7.75 x 5.93m room that is used as a cinema room and a study. I have had a builder in to quote to partition the current cinema area of the room, this would involve building stud walls to create a 5 x 3.6m area so I can install in-wall speakers and a projector. The builder is pretty certain that I wouldn’t need building reg approval but I thought it would be worth checking as it would be an inner room. I have attached a plan I created which may explain the layout better. Does anybody know if this would be acceptable and if so would it need any regs approval? Thanks Karl
