Garage Conversion - with 1.2m ground level difference

[james75]

We'd like to convert our garage and then extend into it. Other houses in the street have done similar - however ours seems to be the only house where the garage is at a much lower level than the house because it's on a hill. The difference in height is around 1.2m.

I've done a very crude illustration of what I'd like to do and was planning on getting an architect/struct.eng to have a look but thought I'd post here for thoughts beforehand.

Does this look feasible or stupid and any idea on rough costs?

So you'll end up having a 4 feet step?

Doesn't sound quite right for a small extension.

Feasible - possibly. Depends upon how favourably the LA will look at the height increase.

Practically speaking you will prolly need to go with a block and beam floor etc. the rest is standard building. Your LA may insist on a stepped cavity tray which will be a pain. Ho hum.

Costs in excess of 18k although you haven't given any sizes?

No, this is to bring the extension up to the level of the main house... Raising the garage in effect (garage roof would end up being 1.2m higher after)

Have you looked at the drawing Norcs?

I'll have to do that anyway I reckon - because as it stands, when we get sustained, heavy rain, water pours down the insides of the garage wall!

You'd have to be a fool to leave out a tray. But all fairly plausible, planning aside.

Brill, thanks chaps.
