I have a thirty day trial of AutoCAD.
I`m going to draw you a picture and photograph it.
Nuff said about AutoCAD for the time being, but I will produce fully dimensioned drawings at some point.
As far as construction is concerned the area where the theatre is going is a 90ish extension to 1905 house.
Some of the walls are 9inch solid, and the morerecent ones are 11inch cavity construction.
Thr theatre is next to the kitchen/family/dining room, on the other side it joins the garage, the third side is next to a 6 foot corridor which joins the boot room to the garage and will have a loo and loads of storage, I will steal some. space for a rack, a rear sub, an a box for the projector.
The forrh side is an external wall. The nearest neighbour is fairly close, and I want to be able to play at near reference level and not heard outside or in the house.
The 4xtension. Is built on strip foundations, between the foundations is filled with hardcore and then concreted. The whole structure is solid, and I suspect ideal for reverberating along with the subs.
Picture to follow, hope this helps and is not too long-winded.
