Raise the floor level


One part of area is my room has a drop. It is almost 6" stepdown from the rest of the room. This is because, the earlier owner, joined part of car garage and breezway and made it a big room.

Car garge is 6" is higher than the breeze way.. Now I want level this floor. In order to do that, I need to to raise breezeway floor to 6".

How do I do that ? What is the general practise ?

Raise the floor level


What's underneath ? Concrete ?
Do you need (want to) insulate ?

If concrete you put down vapor barrier, frame it out & put a new sub-floor down

By code the car garage must be lower than the house. This is to minimize the chance that spilled fuel will move from the garage to the house. Even if you make the garage level with the house, I don't think this meets code. You need to check with your local code enforcement official before you go any further.

Underneath is concrete.

So step one is put a vapor barrier.. is it a liquid ?
Frame it - which is similar to drywall framing, right?

It is no longer the garage.. It is part of the house living space since 1972.

Surprisingly this lin line with the house concrete level. Only the breeze way was at lower level.

What kind of framing I should do.. It is close 6" drop. I need to raise that to 5.5 inch so that I can put 1/2" plywood on top it to make it in level with the other floor. How do I do it ?

Best to use 3/4" plywood, just carpet on top as finish ?

So 5.5" - .75 = 4.75" floor joists
You would need to cut down 2x6's to fit

Vapor barrier usually is plastic - 6 mil

Since I already have a concrete, I think I should be doing the following.

1. put vapor barrier
2.Create a rectunglar frame 2X6.. Fit this frame into the area which is 3 sides walls and one side drop.
2. insert 2X6 (actual is 5.5) into this frame.. are these called as floor joists ?
3. cover it with 3/4" or 1/2" plywood whatever is appropirate to make it level with othere are.

Am I in the right path ?

I do some questions but I will ask once I know I am in the right path.

Sorry for all these questions.. Never done any construction..

Appreciate your help.
