Removal/reconfiguration of an RSJ

[Hellohowareyou112]

Working on a tight completion deadline!

Received this in survey from Edwardian terraced house we plan to buy (this was in response to our request to comment on feasibility of making kitchen and dining room open plan):

The steel supports for the rear ground storey wall removals appear to sit on/in the piers/brickwork which forms part of the partition walling and we suspect that it will be problematic to fully remove the partition wall without extensive new structural steel work and if you do have plans to remove all of the partitioning between the kitchen and dining room you are advised to consult with structural engineer prior to purchase to ascertain feasibility and costs. We suspect it would be feasible to remove the section of lightweight partition walling, however we would advise that you engage a competent builder.

The rooms together measure 23 foot by 16 foot 5. Just how expensive can this work get? 10k? 20k?

A picture paints a thousand words.

Haha very true!

Should add that this is London!!

Where are the steels running? What's sitting on top of them - 2up-2-down or a three story townhouse?

(you need to engage a civil engineer, there are too many unknown variables - it'll be worth investing a couple of grand to understand whether it's even possible, or whether it's a £10k or £30k job)

Thanks! To be honest I’m not even sure regarding the steels.
I would have assumed that they would be across where the wall of the back of the house would have been prior to the extension but I’m not an expert!

So you want to remove the ‘thin’ wall behind the sofa and the doorway to open it up?
The closer thicker end of the wall, with the light switch on the end, is most likely load bearing and has the steels resting on it that hold up the rear upstairs external walls. I wouldn’t touch that.

Thanks! Just realised I forgot to say it is a two up two down. We would like to remove the whole thing ideally but realise it might not be possible!

To remove the lot, you would need a full width steel from the living room pillar (with the two pictures) across to the kitchen pillar (kitchen roll holder) then bolted to it another going backwards to the wall on the far side of the far doorway. The issue is are the two existing pillars big enough? And are they on good foundations? And it’s difficult to see if the pillars are even aligned?
I would not know how much it would cost, but it won’t be less than 20k.

Thanks - this is really helpful
Much appreciated!
