Car port and bedroom on top

[Geo57]

Hi

Just trying to get in my head if the following is do-able, before I instruct plans/SE etc

Am wanting a two storey side extension (a carport on the ground, with a bedroom above it)

The dimensions would be 4.3m out from side of house and be 4.8m long down the side.

Could this be done via the following:
4.3m steel built 100mm into external leaf of existing gable end at the front and back (resting on padstones), to take the cavity brickwork for the bedroom above
Then three brick pillars (say 440mm x 440mm each) down the side to support the 4.8m steel and the other end of the 4.3m steels

My question is:
Subject to a SE confirming that the existing gable wall could take the weight of the 4.3m steels and the brickwork above it for the bedroom at the front and the back, on paper does this sound achievable, or is there anything else I should be thinking about?

Thank you

Achievable subject to the numbers (and planning of course). I'd personally go for a timber inner skin to reduce beam sizes or better yet a full timber construction with render.

Yes. I have built one similar off piers and HD lintels.

Cheers both for the replies

On the same subject, rather than having it as a carport, if I went for an actual enclosed garage with a bedroom over it

I.e: have a small cavity wall built out from the side of the existing gable, to support one end of say a HD catnic lintel and then the other end supported on similar on the other side (as part of a new 4.8m gable end, so in essence it would be more like a proper enclosed garage.

If so, is there a minimum brickwork return for the opening at the front at back? (I see 665mm mentioned in approved docs?), or could it potentially be smaller?

Sorry for the questions, just trying to understand options available for the limited space I have.

Many thanks

Yes probably, subject to an SE doing some number crunching but you'll have an SE onboard anyway.
