I am interested in converting a large, walk-in attic space into a regular room.

We live in a 100 year old house, AND I was wondering what the basics are to look for when starting on this.

What size should the floor joists be, and how far apart?

What should be over these floor joists for floor? right now it is wide "planks" that make up the floor.

How about insulation?

I heard that knee walls are a good way to add strength to the roof structure.

Any other BIG tips on strating such a project?

THANKS!!

 

Jeff Placzek,

Minnesota boy!? Me too!

What you are asking cannot be answered that easily. It appears that you are considering doing this yourself, right? The questions that you ask need to be answered by a professional that can "look at current site conditions." This means from the foundation up! What you are proposing will require planning to sustain the structural integrity for the new space and how it effects the lower floors. Load bearing walls, how far a span you may have now on main floor, sizes of existing ceiling joists, etc. all of this and more have a part to play in how to construct what you are proposing.

I would consider having some contractors look at this to determine what can or cannot be done. Maybe seek a designer or architect for your project. You should be obtaining a permit for this project and you will need drawings. I realize that this does mean some money but without doing this you will get yourself in trouble. Don't try and do this without a permit...not a good thing! If you plan on selling the home in the future, you will have to fill out a disclosure statement and if the Buyer or Buyers Lender requires a Home Inspection, you may be for a terrible surprise! They may even refuse to provide a loan for the home if permit was not obtained and/or if items are not done to code.

Hope this helps!
