PatStudio - Groundfloor extension - design stage

Nice one, thanks!

I've changed the layout again and feel like I'm getting pretty close, just need to sort the ceiling and figure out which "cloud" design to use. Can someone tell me if it's essential that I have an absorbent screen in front of the rear window to improve monitoring? It would have to be moveable, and again I'm thinking of the loss of space. I had an AC guy round last week for some advice on Hvac solutions but he couldn't offer anything suitable off-the-shelf, which is pretty much what I expected after reading the posts in here. So, I've got some more reading up to do I guess. Good news is we're almost watertight on the extension build. :D

most likely, yes you will need it. If not, you'd probably get reflections off the glass coming back at your head, and since your front wall is brick, you'd be setting up an ideal path for flutter echo. Maybe a large gobo on wheels with thick insulation would do the trick? You could just push it out the way when you need the light and don't have any critical listening to do. - Stuart -

.[/quote]OK, so that wall will basically more of a single-leaf than a double leaf, from what I understand.[/quote] Stuart, are you saying that because the walls are coupled that they behave like a single leaf? And if so, how come this is not the case with a standard stud wall with drywall on either side, coupled by the stud? And can someone please tell me how to do this multiple quote thing, its driving me mad!!

So the inside out wall at the front wouldn't have much effect on the flutter echo?

I was thinking of a curved diffuser that I could suspend over the window

Update: After a fair degree of hassle on the house extension build, we're almost finished. Once the building inspector signs the work off I can move ahead with the studio build in August, I've roped in a joiner mate to help and hopefully speed up the process. Pics below show the studio room after a second concrete screed (to correct mistakes on the first), and the adjoining hallway through to the kitchen. My main question at the moment relates to the studio door. My intention is to use the firedoor shown and create something along the lines of Rods superdoor, minus the lead sheet. However, I'm concerned about hanging it from the stud frame of the interior studio wall with all that weight, whereas using the existing frame shown will limit the swing of the door against the (inside-out) stud wall. Any suggestions? Also, I'm guessing I should seal around the base of the skirting boards in the bedroom above? Patrick

Could someone tell me if its worth adding a layer of gypsum board between the studs of an inside-out wall? Space is premium in my room and I had planned to attach only a single layer of 15mm gypsum on the frame, I'm wondering if this would add mass without increasing the wall depth.

Absolutely! It most certainly WILL help. That technique is sometimes referred to as "beefing up" here. Search the forum for "beef" and you'll find out how to do it correctly. There are many examples on several build threads here. - Stuart -

Thanks Stuart :D
