To think this house IS big enough

I have a slightly different perspective on this due to my experiences OP but I’d say go for it. For most of my life between age 7 and 17 I shared a room with my sister and it was fine. For a long period (13-17), we were in a literal shed sharing 2 bedrooms*, one bathroom and no proper cooking facilities with our parents, younger brother and two cats. My sister and I are fine. It’s not an experience I’d repeat for my kids, but it also wasn’t the defining experience of my young life, and you’re not even proposing to do anything nearly as extreme.

*for several months we were all in one large uninsulated space as the bedroom was built. Also, there was no ceiling insulation, so if it rained, you couldn’t watch TV

I think you can make anywhere work, it is a lot more than many people have. The idea that we all need to upsize isn't always realistic when houses are so expensive.

Bit rude.

People are answering your question, OP. You're wondering yourself if the house is too small to do everything you want and need it to do AND add another child into the mix. People are responding with their own thoughts, as they do on AIBU.
And many think YABU. Many don't.

IMO, you don't have a lot of space for 3 teenagers and working from home as your house currently stands. I say that as someone with 3 teenagers, who take up a lot of space and like to have their friends round, and you need to recognise that your 3 will eventually be teenagers. To make it work, you're going to have to do something extension-wise or garden shed wise, etc, and even then, you don't have a lot of space downstairs. It is something to think through.

My god, you really are coming across as very unpleasant.

We don't all have it. Many just keep the amount of stuff that fits.

You’ve asked people if your (small) house can be converted to fit the purposes you have outlined, many have said no and your response is to be super arsey. You are considering buying a house with no potential or storage, and will reap the rewards of your poor decision making or small budget, maybe a combination of the two.

Bloody hell, some if the responses on this thread. Some of you need to check yourselves. A 4 bed house with kitchen dinner, living room and several bathroom options is a lot more than many have. It feels like some people are just coming on to make the OP feel bad.

It's the amount of stuff we all have. Inter/post war 3 bed semis are usually about 950-1100 sq ft, they aren't huge. When they were built, people had less stuff and it was easier to manage. It's not always going to be possible to move when houses are ££££.

I'd ruthlessly declutter, you can get small desks that can fit into the lounge/bedroom and look at storage solutions.

If the garage is a double then there is loads of space to convert and keep storage, maybe even a shower room and use it as guest/office or let the eldest use it. Even a single garage would be big enough for a room and en-suite. You would just have to be ruthless with "stuff" keep a tiny shed for garden equipment. Not many people put their car in the garage so I don't think you will be devaluing the house.

Exactly, you don't require a purpose built space, just a quiet corner.

It does piss me off that employers and I know a few have dumped leases on offices or reduced space to save money but the WFH employee hasn't seen a bean of this cost saving exercise.

The kitchen is a kitchen/dining, it's plenty big enough for five!

Do you have room for a shed in the garden? We converted a small 8x10 ft shed into an office (much cheaper than buying a purpose built garden office), got the windows changed to double glazing, insulated and cladded the inside and got electric run to it. It’s worked really well for wfh and given a bit of extra room.

What’s the total sqf or sqm? The plan you’ve uploaded makes it hard for people to understand the space, especially as they’ve drafted furniture into the only positions it will fit. The bedrooms are small and inflexible - only one is a proper sized room. Apparently the garden is tiddly too. Are you hoping someone will say ‘amazing house go for it’? Sigh.

Meant to add, I WFH as do many of my colleagues and plenty work in their DC's room.

Sorry, my mistake 🙂

You haven't said what ages your DC are now.
Once they are at school, you will have the run of the house to WFH except for an hour or 2 at the end of the day.
Or, if you are both working, they will be in childcare anyway
so again you can work anywhere in the house.

If you/DH are on maternity leave/paternity leave, only one needs a WFH space and that could be upstairs in a bedroom, so the other parent and DC can go about their day as usual.

Is there a scenario I've missed whereby all 3 DC are at home and both parents WFH, other than at the end of the afternoon?

@Coconutsandpalmtree working from home, are you likely to get mega pay rises, how's the promotion tree in your place of work and your partners for that matter. Because one of you will need to pull a rabbit out of the hat to move to a larger property as your baby, small children, morph into tweens and teenagers.

I'd stick with 2 kids rather than cram a 3rd into a small house.

I'd definitely use the biggest room for two kids to share. I have two kids, 2 years apart. They have a bunk bed with underbed storage, plus loads of toy storage all in their bedroom and still lots of floor space. We have a three bed but didn't want one in the loft bedroom until they were older. They love sharing and would continue to for years... especially as we are now having a 3rd child so will need to use the spare bedroom when baby gets bigger.
We do plan to move in a few years. But in the meantime we like our house and it's easy enough to fit 3 small (ish) kids in it. Oh and we only have 1 bathroom 😱. That is less than ideal, particularly as they both seem to need it at the same time every evening. But again....we manage just fine. We'd rather wait and do one move to our forever home then move multiple times and climb the ladder slowly.
