AIBU to be upset by my neighbours' huge extension?

We (family of 5) live in a 30 year old property built on a small site that was originally our neighbour's garden. We bought several years ago from them. At that time, they were doing a renovation on the old cottage as the grandmother had died so that the early 20s DGD and her partner could move in. At the time i was a bit 🤔about it if i'm honest just because my (wealthy as it happens) parents have never and would never give me a house, let alone spend weeks personally slaving over a full blown renovation for me. Since then we have lived perfectly peacefully next door to them.

Now they are doing a large extension. They have bulldozed their whole back garden and the final house will now stretch all the way along our boundary front to back, as well as adding an extra storey to overlook our whole bungalow. The builders literally have to work on our land all day to build it. They have even had to remove a small section of our drive to lay foundations. They have moved out for the duration, i assume back with mum and dad for free. We are stuck here.

I know i am not being unreasonable to worry that their huge new extension will be ugly, dominate our space, reduce our privacy and probably damage the value of our house.

BUT we love living here, love the area, school, public transport, other neighbours etc. Our house is worn and lived in as everyone's is that is 15 years into this parenting caper.

I am aware, as you will now be, that I am being bitter and twisted on the subject. How can i continue to like living in our home? How do i avoid turning into one of THOSE people that has a stupid one-sided vendetta with the neighbours? How do i avoid being resentful that they will have a massive, polished home for the two of them, while we slum it over here with 5 of us in a cottage with one bathroom and a kitchen made of MDF? How do i forgive them for choosing to use every centimetre of their land when they must know it is at our expense?

P.S. The development meets local planning regs to the milimetre so don't bother with planning arguments.

Presumably when they applied for planning you would have had time to object? The notices are always posted way in advance.

To be honest you come across as simply jealous. Jealous that someone's family have given them a big house, although you don't know if that's the case or what conditions are attached.

And jealous of that your parents haven't done it for you. After all there was no reason to mention your parents financial situation.

You will always always meet someone better off than you, someone who's got a bigger house, richer parents.

You say you love your house with the MDF kitchen, you say you are slumming it... but you actually own the house, read the threads on here about people who've got shit landlords or living in social housing which isn't up to standard or have kids who will never afford to move out.

@ElfinsMum What's your point? You rolled over at the meeting and now you don't mind anymore?

Mapleleaf114 · 17/03/2026 05:16

You seem to be bitter about that they are better off in a bigger home and have generous parents,unlike yours? YABU, whatever build they are doing it cant be that bad if its within planning regs, las dont mess around with it, they do consider neighbours and you dont need to even make a complaint their planning office will pick it up.

deal with the unreasonable juvenile envy

YANBU to be upset but I suspect the answer is just ‘get over it’. You yourself have benefitted from a plot that used to be someone’s garden. Now they’ve decided to use all their garden space too - nothing you can do as you say, it meets planning regs. If it makes you feel any better, our neighbours were planning building-wise a few years ago that really upset me - I thought it was massively going to infringe on us in terms of noise, light and privacy. I even went to a council meeting and spoke against it. It went ahead anyway and now doesn’t bother me at all.

They are being selfish. Are they trying to force you out?
