Looking at the roof cassette designs from my timber frame company it appears as though there is no ridge beam. That makes sense with the panels joining flush but if there’s no ridge beam I’m wondering how to fix the roof dry ridge tiles which would ordinarily go into the ridge beam?

I’m trying to get advice on fixing counter battens to 18mm osb cassette roof. I’ve read some articles suggesting they should be screwed rather than nailed but others saying nails are ok. Any advice welcome? Thanks

Thanks @saveasteading the engineer specified a silt trap presumably to improve efficiency of the soakaway? Any thoughts on how much distance from top of crates to surface? Thanks

Looking at building the soakaway for new build timberframe. Our engineer has recommended 5.6 x 1.2 x 1.2m . Comments from builders are that this is excessive but we do have slow draining clayish soil so likely going to work close to this. I'm ok with digging the trench and the general construction but wondering how far below the surface of the lawn the top of the crates should be. We're also going to install a silt trap so not sure whether this will also affect the depth at all. Any advice greatly appreciated. Thanks

We’re having a timber frame with cassette roof erected soon. I’m going to be tackling the roofing myself and looking for information / advice / tips about layers, materials and details. My understanding is that I will need to add: 1. breather membrane 2. counter batten 3. Battens 4. Tiles (Wienerberger Rivius) Questions I have: - what’s the best way to secure membrane to osb? - do I need an extra breather membrane between batten and counter batten? - What kind of fixings should I use to attach counter battens to roof cassette (18mm osb top layer)? - what kind of fixings batten to counter batten? - tips on eaves/verge details - any sequencing tips particularly eaves lots of learning to do so any help greatly appreciated. Thank you in advance

Edit: 18mm osb

I’ve also seen some diagrams that show no soffit on cassette roof eaves detail as the cassette essentially is the soffit (I think)… an I missing something?

Thanks @Mr Punter I won’t be able to add cladding/render to the walls until much later so hoping I can allow for this when doing soffit? With cassette roof to cassette walls I’m assuming only ventilation is over fascia but struggling to find a diagram that shows what is needed clearly. Thank you

I'm building a new timber frame home. Walls will be osb on the outside so will need fishing with vapour barrier, battens, render boards, render. I'm considering installing the render boards myself (with help from family/friends). A local company that has also quoted for the render has advised against this so I'm wondering if this is something that's beyond the diy job or not? I realise boards will be heavy but from what I can tell installation isn't too difficult. I'm pretty happy researching and trying my hand at most things. Does anyone have any advice or experience of doing this yourself? Thanks

I’m about to embark on building our own house. Much of the work will be done ourselves but we have a contractor to lay foundations (raft slab) and another to build the timber frame. I’m wondering if I can split the project into these 2 distinct phases so that contractors are not on site at the same time and therefore easier to manage in terms of CDM? Presumably by only having one contractor on site each will assume principle contractor responsibility for their phase?

@Nick Sheppard just seen another of your posts…. Are you able to offer advice here? Thanks

I know this has been discussed lots and I’ve read many but would like direct advice on our project… We are about to demolish (ourselves) our existing bungalow and replace with a timber frame house. We will be using 1 company to do groundwork/foundations. Another company will supply/erect the frame to wind/watertight membrane. I’m going to do as much as possible myself, prepping site, roof, first fix etc. I had a meeting on site this week with architect, engineer, groundwork company and timber frame company. There were lots of questions/comments about CDM responsibilities; who is construction manager etc. I was more than a little daunted as haven’t really explored this. Slightly happier after reading up but would like to know where my responsibilities lie, tips on making this smooth and any useful resources. Thank you in advance for everyone’s help/advice.
