As per title, I'm considering a new build (yes, I know) and one of the ones I'm looking at is a semi. Most of the site is up now but handily there are some google earth shots from when some of the semis were being laid out.

As far as I can see this looks like a cavity wall between them, would this provide better sound proofing than usual or have semi-detached had a wall cavity for as long as anyone remembers and this is basically nothing new or remarkable?



I did previously live in a 2005 built semi and it was OK but possible to hear loud music through the wall, but I'm not sure if building regs have improved since then.

in theory it should be great,
it all depends on the site monkey, and whoever is supervising,
it only takes a couple of small voids to cock it up

you can ask for the sound test results,
only about 1 in 10 get tested,

No idea for construction but what's the layout, is the stairs shared in the middle etc? If the likely wall a TV and sound bar will be mounted on is against a shared wall then I don't think most sound proofing is going to save you from a loud music enjoyer...

Ah interesting, I'll ask about that.

There is a detached I'm also looking at but it is REALLY stretching the budget to the point that for at least the first few years of living there I will have no social life and no buffer, all of my money would be going on mortgage payments which leaves me a little uncomfortable even though the house is perfect.

I built a couple of pair of semis a few years ago, they were built to regs and the sound test was above and beyond a pass, the test guy actually commented it was one of the best he had done. You could still hear noise from next door, not bad but not perfect. I live in a 30 year old semi and it’s pretty awful, my last house was 20 years old and far better. In short, it’s hit and miss and really depends how loud your neighbour's are.

Ask the site agent if they apply a parge coat (sound coat plaster) at first fix stage, this goes on quite rough but seals the wall, usually before stud walls go up so they cover the complete party wall.

Sales staff probably wouldn t know so you d be best going into the site office when the site agent is there.

Or poke your head in a plot before it gets boarded, if the party wall looks like it s been rendered it has a sound coat on.

Interesting, but I guess proves why I've got some concerns, you just don't seem able to tell even from looking at the specification.

My G/f has a new build semi.
She has a yappie dog and nextdoor say they dont hear it, and they have a baby and she doesnt hear that, might help that both sets of stairs are on the joining wall.
When ever i stay there ive never heard next door at all.

In theory hall adjoining and hence stairs on the party wall are better for sound proofing ( or not noticing it ).

My experience was the opposite. Feet thumping up and down the stairs. I moved.

At the end of the day I think it is down to your neighbours with any semi. The next house I lived in was a semi and I never heard a thing. They were both similar age and construction.

We lived in a new-build (15 years ago), couldn’t hear the neighbours at all except when they slammed their front door, which was often.

The neighbour was a vile hag, living in such close proximity was a real issue for me.

What if the buyer of nextdoor decides to rent it out to a housing association etc

Tread carefully.

Go for it. You will find a way smile

You will be in a great position later and really will be happier.

When we lived in a new semi there were no noise issues but oddly kitchen smells seemed to drift in quite frequently.

We lived in a succession of Victorian/Edwardian terraces - you could hear the neighbours in all of them - especially the piano playing sound composer next door to our last house.

Son's GF lives in a modern semi and sound transmission is still there. I suppose it depends on your sensitivity/tolerance to other people's noise.

We moved to a detached.

I was busy googling last night to find out how much extra I'd take home after tax if I just got a second job for a little while lol. The answer is (predictably) not a lot!

This is the answer. You'll always be wishing you'd have opted for the detached.

But good luck whichever way you go.

yes

Before where we are now, we lived in a reasonably new (2019) semi and other than the occasional noise when our neighbours had their cleaners in, we heard almost nothing, and vice versa. The people who bought our house were/are evidently much noisier than us and our old neighbours have said they hear their new neighbour’s TV, music etc. every evening, all evening.

We would never buy a semi again.

First house was a 1980's estate built semi (stairs on party wall) but could still hear everything thro the walls - hated it

Second house was same size but detached - huge improvement

Third house (current one for 35 years) was a bit of a state when we got it but enabled us to get a slightly bigger detached - there is no way I would go back to a semi (I'd rather have a very old terraced with solid walls)

I live in a 2009 detached (worth the stretch) & one of my neighbours opposite (living in a semi) is selling up as they can hear the neighbours through their party wall (spoilt brat toddler screaming & shouting at all hours). Bedrooms two & three & the kitchen are on the party wall.

My advice would be to go for the detached house if you possibly can. I would suggest that no matter how good the soundproofing (and I recognise that it could be really good), if you get attached neighbours with the whole smash of barking dogs, screaming baby and a couple of other children, you will hear noise whenever at home.

The new house should be exciting and joyous, and a few years that are tight financially are, I think, a price worth paying.
