Caversham Build

@Iceverge @CharlieKLP These comments are making me more stressed and less confident. So i'm going to bow out of this discussion and make the best decisions i can without any more assistance. Thank you to everyone who offered me constructive feedback.

Hi all, okay i have gone back to the drawing board and simplified. how does this look? I cant make the drain lower than the DPM unless i put insulation under the DPM rather than over as i have already poured foundations and hardcore

I think i am losing a sense of why i was trying to do this in the first place.🤯 I thought it was to try and stop water getting into the building in the first place in the event of very wet ground or flood - but that's tanking right? So with a DPM detail thats more standard - i'm, in general, obstructing the transference of moisture from the outside to the inside. BUT if the building gets very wet or there is a flood a more standard detail will allow me to dry things fix things out more easily? I'm so confused

thanks @saveasteading do you mean the water will more easily travel out of the soil and into the gravel channel around the outside of the building?

Thanks @tonyshouse yes my house is about 500m from the hydro, great little scheme. Self building is a steep and stressful learning curve.

@tonyshouse@Rob99 and anyone else - how about his detail below i've just drawn? Taking into account your feedback - my question is will this many bits of plastic (DPC/ DPM) in the outer leaf of bricks / blocks cause any structural issues? thanks for your help

@tonyshouse thanks for your response can i please ask: Can i use EPS for below ground level and rockwool above/ - my bricklayer who i have been trying to keep sweet as he is very good and they are in short supply told me to use Rockwool i think it makes his life easier. Floating floor - as in lose the wooden joists bridging the slab?

Hi all, me again, Thanks for all your help so far. I have another question I want to protect against ground water / rain water / holy water the lower 500mm of my outbuilding, as it is below GL in a quite wet area. My first detail was this : But i have come up wit this detail instead which, to me, will do a better job and much cheaper: pretty please please could you tell me if this can work / share your wisdom apart from the 'change your design so its above ground level' wisdom thank you

thanks please do point me int he direction of one, i cant seem to find any simple fixed glazing windows that have a simple thin frame like this

@saveasteading thanks. when you say my proposal looks solid, are you referring to my most recent 'internal frame' detail ? thank you

Thanks for the help / advice everyone here is my latest design, it means i would have a 25mm frame around the glass but i think the sightline on the glazing units are 12.5m anyway. Again please do tell me why this design is not possible if you can I'm still tempted to try the original design, you only live once and we'll be knee deep in world war three soon.

this is interesting. so in theory if i can attach glazing bars to the brickwork (flush pointed) and line them with the epdm foam on both sides inside and out as per the diagram. This will allow me to mount the glass in between the two returns. if i left my self 10 mm either side for an expansion then i could probably get away with a 20 - 300 mm profile. i would need metal glazing bars that i could screw into the wall and then finish with a strip. i guess this is essentially just thin framed glazing that i build myself right?

Thank you for your input Jilly Can anyone actually recommend a reasonably priced thin framed glazing unit / brand ? Everywhere i look the description is 'frameless' or 'minimal' frames or 'ultra thin frames' and the frames turn out to be minimum 60mm - i would be happy to put an internal frame on the brickwork if i could get the profile down to 30mm or less. thanks

Hi JohnMo thank you for taking the time to respond, Have you checked you have allowed enough room for the glass thermal expansion and any settling of building at sides, bottom and top of glazing. No i've not allowed for expansion or settling, could you give me a rough guide figure? All you sizing looks tight for easy assembly, the rubber glued to the glazing may cause hang ups when trying to insert in to block work. i was planning to glue in the 3mm rubber strip onto the brickwork channel/dpm, then once i have lowered the window in from above, push it up against the 3mm rubber strip and wedge the 10mm rubber behind it. - should i give it more space anyway? Do you need a weeping hole at bottom to prevent any water accumulation? I'm not sure. do i? do you mean in the sealed glazing unit (i'm guessing not) or somewhere else? - where would the water accumulate? squse all these amateur questions but i really am an amateur thank you
