@Adsibob thank you that make sense... Definitely something i need to consider as there is a step down to the patio which i had only considered raising. I think an actual step may not be too bad... Its the current small lip that bothers me 😁 much appreciated again 🙏

Thank you both so much for the replies, I have been googling all sorts to try and get it straight in my head....was getting nowhere fast! @Mr PunterI had completely overlooked if I raise the roof, the available pitch probably wont be sufficient for anything but a flat roof due to the low first floor windows, thanks so much for clarifying that a different roof height to neighbours is possible I just couldnt figure it out as the extension was obviously done on both properties simultaneously. Really appreciate this 🙏 @Adsibob very interesting, honestly I am not sure how that could work, as the other parts of the downstairs and the dining room actually already have fairly tall rooms (2.6m) and I would like the floor to be level. Did you lower the floor in the whole downstairs? I actually do need to lower the floor in the kitchen& dining room or raise the floor in the rest of the house as there is currently aprox 5cm difference and it drives me crazy. I definitely think I have bitten off more than I can chew with this 🫣

Hi all, I'm looking for some advice before approaching architects or structural engineers. I've recently bought a semi-detached house that needs quite a bit of work. There is an existing single-storey side extension off the original kitchen (which has a hipped roof), creating a dining room at the rear with a flat roof. Both the kitchen and the dining room roofs need replacing, as highlighted in the survey. The flat-roofed extension is joined to my neighbour’s identical extension. I’ve attached a photo of the house (with a rough yellow line marking the boundary between our properties) and the floor plan Here’s what I’m hoping to do: * Remove the wall between the kitchen and the dining room * Widen the opening on the rear wall * Raise the kitchen ceiling height to match the dining room ceiling. My concern is this: The current roofs don’t meet insulation regs. I’d like the RSJs hidden within the ceiling, but I don’t want to lose any ceiling height inside. This likely means raising the entire roof level, which would result in my roof being higher than my neighbour’s. I understand this would require planning permission, but from a practical construction standpoint, is it doable? Additionally: I would prefer a mono-pitched roof, is that possible given the fact the extension is joined to my neighbour’s. (If a mono-pitch isn’t feasible, I’d accept a flat roof.) Any thoughts or experiences with a similar setup would be greatly appreciated. Also, if anyone can offer a very rough cost estimate for this kind of work (I'm in the North West), that would be fantastic. Thanks in advance!
