Garage conversion

speedyrazor

Hi, i'm also thinking of doing a garage conversion but my concrete garage floor is about 12 inches lower than the floor level in the rest of the house. What are my options for raising this up?

Kind regards.

Damp proof course and more concrete.

You need some insulation as well 4 inches of celotex should do it. But may be 6 of expanded polystyrene would be better to save on concreate

Concrete is an expensive way of doing it. Put is a suspended timber floor.

Put in a timber wall plate either side of the garage. Set it 22mm lower then the floor in the rest of the house. Suspend joists between the 2 wall plates at 600mm centres Put in ordinary mineral fibre insulation between the joists. Then secure 22mm chipboard flooring across the whole suspended floor and this will bring you to the same height as the rest of the house.

Hi, thanks for your reply, for a single standard size garage roughly what would be the cost to concrete as aposed to a suspended timber floor, I need it to come up about 12 inches.

Kind regards.

I have seen them do this a lot on home improvement television shows. Usually what they do is build some sort of platform to raise up the floor as necessary, but you would have to be careful to make sure it is properly engineered to support the weight. (See HGTV.com for some ideas - it seems anytime i turn on the channel that is what they are doing, lol)

Is there any reason as to why not just keep it as it is? Sunken rooms are common where I live. If you needed to for better accessibility reasons simply build a small ramp if you would prefer that over steps. It might be a much more cost efficient solution - though as one person suggested already insulation might be a good idea, especially if the room will be heated/cooled since garages are not always the most energy efficient rooms for heating and cooling.
