Thank you for the response. Not in a conservation area and the house is detached

Correction, a 300mm ladder overhangs the gable, plus 100mm tile over hanging the end of the ladder. Dormer is therefore set in 350mm from the outside of the external skin on the gable wall

I’m having a dormer loft extension at the moment and the existing roof structure includes a 400mm overhang with laddered rafters plus another 100mm tile overhang beyond this to the verge. The approved planning drawings indicate that the dormer cheek will sit 750mm from the verge, so taking into account the laddered rafter plus 100mm tile overhang, the dormer cheek was set to be 250mm in from the outside of the outer gable skin. The trimmers for the cheek have been formed, but my builder says that the 100mm tile overhang must be reduced to about 30-40mm once the roof is re-tiled, as we are having a continuous dry verge. Would this be an issue with planning? The cheek is still where it is meant to be, but the distance to the verge is reduced. I’ve asked if the 100mm overhang could be maintained and he says it can’t - any thoughts on whether this can be maintained once the roof is retiled? Thank you

Thank you Annker. Yes I appreciate perhaps I didn’t work my comments correctly. BCO is visiting on Monday and I’ve emailed the engineer. It really does not sound right to me so let’s see what they say. thank you again

I would appreciate some insight on this. We are building a single story rear extension with a block and beam floor. There is a ground beam spanning the rear of the extension which has been meshed and encased in concrete. There is no foundation under this ground beam, it rests on a trench on one end, and a pad on the other. The external blockwork is not running straight along the beam, and as a result, on one end we only have 100mm of concrete encased beam left for the 150mm cavity and thermalite internal skin. The blockwork has been built square however the beam must not have been laid the same. I spoke with the builder after noticing it and he says it’s fine and the internal skin and 150mm cavity will be built off the block and beam that rests on this 100mm. Does this sound correct? unfortunately my building control drawings do not detail this.

Thank you. I am concerned that with the render option, as this is a retaining wall (lawn), we would have problems down the line with water damage to the render

I require a new retaining wall in the garden, 0.6m above ground level and 18 metres in length including a few slight bends. The current plan is to build from blocks and then clad with some form of stone cladding. Whilst in London I came across this and wondered whether it could work as an alternative, avoiding the need to clad, and offering integrated seating into the design. I imagine it would be easy to power wash and I wouldn't need to worry about damaging any cladding adhesive with this option. I have called around a few pre-cast concrete suppliers and none seem to be able to offer this. Does anyone have any suggestions on where I could look into this further? Am I crazy to think this might work out cheaper than building with blocks, cladding, and then sorting an integrated seating option? Any ideas welcome Thanks Adam

Hello I have plans for a cold roof on a loft extension. I believe cold roofs can be problematic with heat retention in warmer months. The rafters that are currently spec’d are 200x47mm and total cold roof thickness 342mm. I am wondering whether a warm roof could be a better option, but I do not want to compromise on head space. If my engineer agrees to say a 125x75mm rafter instead of 200x47mm, what is the minimum thickness warm roof we could achieve here? any input greatly appreciated

Great, thanks. At least I’ll be better informed when negotiating with my builder with a comparable quote

Do fabricators quote to both supply and fit?

Here are the drawings Nod

Well 90kg per section so not sure whether a crane is required or not.

Thanks Nod, just to be clear, priced separately are all other works relating to the loft extension, this £5250 is just for supply and instal of the steel ridge

I would be most grateful for some advice here re some additional costings during a project. I am the homeowner and appreciate that additional work is required: - supply and fit of a 152x152x30 (9m span) steel ridge beam in a loft. It can be spliced in 3 sections if preferred. There is an existing loft extension but after strip out we discovered there was no ridge beam so this has been spec’d by the engineer. My existing quote from the builder includes scaffolding and all other works related to the dormer construction. Priced £5250 inc vat. - Marley duo concrete roof tiles for a 55m2 pitched roof including re-felt and battons. New lead flashing, UPVC fascia, softfits and dry verge, guttering to this area only. Priced £12840 inc vat. again scaffolding already in place
