ATTIC CONVERSION

My attic is built with 2x6 rafters (18" on center/#2-btr) and 2X4 joists. The area is 40' long and 28' wide and has a center height of 7'6". I would like to convert it to a simple "play room" for the kids. Am I crazy for even thinking about it? I'd be doing most of the work myself but would probably go to a structural professional to ensure the design doesn't mess up the house structure. What's the cheapest way to get a simple design -- what would be a reasonable amount to expect to pay for something like that?

 

The problem are the 2x4 joists. I strongly recommend you get some one with a working knowledge of load distribution. This is not a do it yourself job.

 

Hello
There are many thing to think about....fire exit, stairs, ventaltion, windows, insolation, electrical, heat, and structual.....but the code does not allow ceiling hight that low you need an average of 7' in a room.....after you up size the ceiling joist you will not have 7' at the highest point.....Good Luck.....

Greetings,

The previous info is right.

One other thing, as an insulation contractor I can assure you that you can wind up with a hot box up there if the right insualtion is not used. If you get that far let me know and I'll give you info on how to do it right.

Thank you for considering my opinion.

 

OK -- Upon closer inspection, I discovered the rafters to be 2X8s on 18" centers and the joists to be 2x6s on 18" centers -- does that make the project more "doable" -- that is, with less concerns on the structural impacts?

The minimum headspace issue concerns me -- is there a way around it by designating the room for something other than a routinely occupied space? What I really want out of this area is a place for my kids to have all their "stuff" out for playing without trashing the rest of the house. Lacking that, is there a waiver process for something like this? To maintain 7' average, I'd have to build a room that resembles a bowling lane.

Also, what's the best way to go about getting a design done? Should I go to an architect or is there someway less expensive? What I really need is just enough of a design to:

a) Make sure I don't mess up the house and
b) Get the design approved by the city for inspection.

I have heard about the importance of good ventilation/insulation work on this kind of project --- as things progress, I will definitely be looking for some advice.

Thanks for the responses.

 

What I would do, is take a sketch of your plan to your permit department, and explain to them your questions, and concerns and ask them what they want from you. They will tell you what they need. It may be that you will not be required to get an engineered drawing. It might save you a bunch of money.
