Lowering a concrete floor

[rossmalone]

Hi guys,
I am working on a 3 bed victorian terrace house. The front benefits from high ceilings but the rear addition is low and makes the room feel pokey. I'd like to lower the existing concrete floor by 245mm to give the additional headroom.

Does anyone have any advise on how to do this? Is it likely that I will dig under the existing foundations?

Best wishes

Ross

How low is 'low'?

Or better still, what is the difference in height betixt the two ceiling heights?

There may be the scope to lower the floor level regards foundations but bear in mind that there may be other things under the floor that may not be so easily lowered or shifted.

The dpc will also be an issue meaning that you will have 3 courses or so of bricks giving you a damp headache.

Electric sockets, light switches and radiators may all need lowereing.

You may also need to nail on an extra foot onto the bottom of the door or at least lower the head.

I personally think your idea is a bit bonkers.

Your in for a whole world of hurt if you try this. Fair enough for digging out a basement etc that will be tanked and not have anything much under it but in a ground floor room it's asking for trouble.
