I'm wondering if someone in the building trade or just experienced in these things can offer some general advice when it comes different house constructions, or whether it's all way too variable to be worth generalising about. To give a bit of background - for one reason or another, I have mostly lived in detached properties so haven't had to worry too much about direct noise transmission, party walls and so on. However, as a family we are now expecting to move in the next year or so to a more expensive area (school catchment issue) and most of the property in our price range is likely to be semi-detached or terraced. Unfortunately I am a light sleeper (and don't get on that well with ear plugs), so the first concern I have is over potential noise when sharing a wall with a neighbour. I appreciate each house is different, but wondered if there are any general rules of thumb, like beware houses built between X and Y dates or by certain builders because the sound insulation was usually poor. Our current Barratt house was built mid-nineties and internal soundproofing isn't great, but I suspect isn't as bad as some. I'd also appreciate any other relevant tips on adjoined properties vs detached, and more generally on any characteristics to be aware of when looking at homes of any particular era... whilst we'd love a property with bags of character, it's ultimately more important in our case to have something that is reasonably low-maintenance. Again, maybe there's too much variation out there for anyone to really be able to say, but I thought it worth asking the question (the area we're looking at is in Yorkshire, in case that makes any difference). Lastly, I'm also wondering if there are any common themes with new builds these days, again on the noise front but also any particular modern construction practices to be aware of - good or bad - which may influence our decision on whether to consider a new build (I remember how a friend bought a new home and drilled into the wall, unaware that the pipes are not only plastic and therefore not picked up by a pipe detector, but also run diagonally across the wall so unfortunately he was unlucky enough to drill just at the wrong point!). I tend to be wary of brand new housing given some of the quality and snagging nightmares I've heard about, but I don't think we could or should rule out the idea completely. Thanks in advance for any help you can offer.
