Cliff Hazard Posted February 18, 2015 Share Posted February 18, 2015 Does anybody know the rough price of knocking through an internal supporting wall, installing an RSJ and making good? I'm not sure yet if it's Manx stone or brick, I imagine it would cost a bit more on labour if it is Manx stone. many thanks Link to comment Share on other sites More sharing options...
wrighty Posted February 18, 2015 Share Posted February 18, 2015 Had something similar done a few years ago. You'll need a structural engineer to calculate the size of the RSJ required and the size of the padstones. Is it just a door you're putting through or opening up the whole wall between 2 rooms? If the latter, the neatest way will be to have the RSJ put in the ceiling space with joist hangers in it for the floor above, rather than having it as a visible beam across. Cost - don't know. Depends on size of the opening, how thick the wall is, what the side walls are like etc. I can recommend the builder that did mine a few years ago if you like via PM.

Cliff Hazard Posted February 18, 2015 Author Share Posted February 18, 2015 Thanks. Yes we want to open up the 2 rooms, I hadn't considered that the RSJ could be put into the ceiling, that would look better. We do have a builder in mind already but yes, if you could also recommend someone so I can get a comparative quote, that would be great? cheers Link to comment Share on other sites More sharing options...
Max Power Posted February 18, 2015 Share Posted February 18, 2015 Don't get O'Reilly to do it though... Link to comment Share on other sites More sharing options...
Katman Posted February 18, 2015 Share Posted February 18, 2015 If you go for the RSJ hidden in the ceiling (if you have enough depth) you will most likely be looking at double the labour cost of just having one below the ceiling and boxed in. It does look better though. Link to comment Share on other sites More sharing options...

topbox Posted February 18, 2015 Share Posted February 18, 2015 Get a structural engineer to calculate the lintel and pad stone requirements which you can then use for the relevant Building Regulation application. Link to comment Share on other sites More sharing options...
Terminal Posted February 18, 2015 Share Posted February 18, 2015 Ah just knock it down. It'll be right enough. Link to comment Share on other sites More sharing options...

Monkey boy Posted February 18, 2015 Share Posted February 18, 2015 What is the wall supporting? Speak to the builder before the structural engineer. Link to comment Share on other sites More sharing options...
Addie Posted February 18, 2015 Share Posted February 18, 2015 Make sure that any builder has public liability insurance before you let them touch a thing. Putting an RSJ under the ceiling level and leaving slightly protruding sections from the side walls will probably be the least expensive option.

AcousticallyChallenged Posted February 18, 2015 Share Posted February 18, 2015 Sledgehammer, and some gaffa tape would work, right? Link to comment Share on other sites More sharing options...
Cliff Hazard Posted February 18, 2015 Author Share Posted February 18, 2015 Thanks very much for the advice. I haven't moved in yet so am unsure of exactly what needs doing. The wall is supporting the joists above, I think. It's one of the 1st things we want to do with the place. will I need to get planning permission? I didn't consider a structural engineer, I hoped just a quote from a builder would do. Gaffer tape!? Probably overkill I think, I only want it to hold for a few minutes. It's not the Guggenheim.

paswt Posted February 18, 2015 Share Posted February 18, 2015 The wall will need support ("needles")when you break through as will the ceiling joists to each of the rooms (with "acro" props). If the construction is brick it's relatively straight forward if it's random stone/ lime mortar it could be " problematic ". I've had the odd nightmare with a flint /random rubble wall . It may be possible to 'lose' the wall protruding down into the room resulting in a flat ceiling throughout the two rooms but it is a tad more expensive , but I think it looks better If you have no experience with this type of work I would think it prudent to take on board the advice you have been given (above) and involve the local building control officer. Good luck and I wish you well Link to comment Share on other sites More sharing options...
topbox Posted February 18, 2015 Share Posted February 18, 2015 Building regulation approval will be required for structural works, planning permission not necessary unless the building is Registered. You will need plans and calculations and there is a fee see https://www.gov.im/categories/planning-and-building-control/building-control/making-a-building-control-application/ Link to comment Share on other sites More sharing options...
