Hi,
Apologies if this is in the wrong section but it seems most relevant to me.
Firstly, this is a problem I'm encountering as part of a larger project, but I'll try to focus on the actual problem itself and not wander off onto the project.
My house has an outside toilet which is part of the main structure of the house with a bedroom above it. There's a rough diagram of the floor plan at the following URL:

I plan on having a builder block up the outside door and knock through a new door (labelled Door 2) and use the outside loo as a utility room.
At the weekend I removed the toilet and associated plumbing. In doing this I broke apart some of the concrete floor so I could remove the top of the soil pipe and cap it off. At the time I noticed (and since then the Building Regs bloke has commented on) the fact that there appears to be a cavity under the concrete floor. The concrete looks to be about 1 to 2 inches thick and broke apart quite easily when I removed the soil pipe. There also doesn't appear to be a damp proof course under the floor.
The Building Regs bloke suggested breaking up the concrete, using it as hard-core then laying a DPC over it and concreting over that. Does this seem like a good suggestion? Can anyone think of other options available to me?
I've little to no experience of laying concrete and while I don't mind tackling it myself I can't see how I'll get it flat as the room is about 8ft long and I'll be working from the outside doorway.
Can anyone offer any tips/advice/suggestions?
Cheers,
Ian
