Attic

[decorators3]

HI  

 

Not sure how to go about this but here is the clients wish list..

 

- Build a garage 24 x 24 with 9ft ceiling

 

- Build an in-law suite  16' x 24' above the garage with 8' ceiling 

 

- Exterior entrance to in law suite

 

I'm pretty sure in order to do this I have to have the exterior walls of the 16' x 24' room extend through the roof on one side in order to have an exterior entrance.  but I'm thinking this will be off center

 

Attached is an exterior image example from google search ( only interested in the attic area )  of how I think it will look will work unless you have other suggestions which would be greatly appreciated..

 

I've never been asked to design this before 

 

Cheers

Levina

Build the in-law suite as another floor on top of your garage.

yes I can do that but 16 x 24 will not be same as the 24 x 24 floor below

Sounds like you are going to want knee walls to make the attic space smaller than the floor below.

Just design it any way you want it...then roof it.

yes I can do that but trying to figure out how to get the exterior walls to  protrude through the roof like the image I attached...

I don't think that image is what your client is asking for. I think they want an attic room contained entirely within the roof, with knee walls as someone else said:

 

 

 

It can easily be done with trusses called attic room trusses or bonus room trusses. The second story walls do not protrude through the roof. The 8' ceiling will be in the center of the room, with a sloping ceiling.

ok  Ill follow your information guide thanks - so will it be viable for a 16 x 24 ft room with kitchen bedroom bath etc

Chris is correct about attic trusses; I just finished this bonus room over Master Suite addition.

These are 4'10". The owner wanted to drop the ceiling enough to have 12" for extra insulation. Here is the section.

You may not need the attic/turned into living space concept. the image posted appears to me to just be a second storey as the second storey walls look to be bearing on the first storey walls. if they want 16x24 on top of a 24x24 garage, I would just put a first storey roof over the back 8' and align the three walls to the garage walls at the front, and if they want a vaulted ceiling starting at 5' on the sides(maybe to meet height restrictions?), then draw in ceiling planes to give you the roof trusses. The front gable does not look like a real gable, it looks like an eave drawn to look like a gable.

 

But if I were them, I would build 24x24 on top and if they want the back 8ft to be nothing then just make it storage. You  can dress upt the roofs how you would like

 

As you are in canada, beware the outside stairs, if conditioned, you will need to pipe heat in there,  or you can put a door at the top and leave unconditioned.

 

In alberta, the outside stairs are a "tall wall" and will require engineering.

 

Also, not sure how your jurisdiction treats limiting distance. Here I have to draw an imaginary property line between the garage suite and the house and then calculate unprotected openings and ensure the aggregate is less than the table in the NBC
