Footing Question

[padstar]

I am pouring my footings on Friday and have a query. The ground level falls away from the house.

I had planned to pour the footings to a level 525mm below my internal floor level/DPC to allow for 2 blocks and a brick below DPC.

If i do this the top of the footing will be quite close to ground level at the rear of the extension. Is this an issue or do i need to pour it lower (i would rather not step it if i dont have to)?

Is 525mm from the floor level the correct allowance to work to when pouring.

So finish floor level to existing footing is more like 800mm do I just pour to the same level and gauge up with more courses below dpc?

Hasn't the building inspector approved the trench?

Yes he is happy with it. Just wondered if the top of the concrete needs to be a certain depth below ground level or it doesn't matter. I assume it doesn't matter

No it doesn't matter, you can full fill the trenches if you wish.

No, just crack on.

Thanks. Footings being poured today and blocks turning up tomorrow.

Works out to be 3 blocks and a brick from top of footing to DPC.
