I live in an area where houses are expensive to rent and wages are low in comparison. We are a family of four and live in a flat (about 850sq ft) by the sea and a lot of families live where I am (a lot of them are holiday lets and aren't even occupied a lot of the time, so that has driven up prices
). We have a small bit of private outside space and some great communal areas, but have a great view, beach and amenities close by which makes up for it. We do have some interfering idiots who aren't happy about kids living here (I think they were hoping for a retired community instead, but I say sell your second homes/rental properties and then you will get one - we need to live somewhere!). However other than that it's ok and we manage.
Space is tight as we obviously don't have an attic or shed for storage, so you will need to declutter - I'm forever doing it.
One thing you will notice is that flats are built as holiday homes or for young professionals, so kitchens might be small and you will have a second bathroom you wished was more space for another room. Sadly they don't build flats for family life here, more for investment properties, which isn't ideal as a lot of families live in flats.
Some of the tips I suggest are:
-Declutter monthly
-Bunks in rooms for kids or a trundle as this saves space
-Make use of storage on top of kitchen units and have designated boxes
-Ikea kallax is great for storage
-Get the best flat you can afford in an area near decent green/outdoor space and you won't miss garden as much
-Be mindful of being able to park if you need to as some flats will have limited parking.
-Wooden floors if lounge, kitchen, diner is open plan. I have a two year old and the carpet and sofa are never clean.
I do like apartment living as you always know where your kids are, which for me is a bonus. I think if I move to a house it will feel smaller as we would be on two floors and we would probably be paying an extra £200-300 quid a month for a small garden and attic as the houses are not that big round here.
I have had a few snobby comments from people that I need to move into a house and I would like to eventually, but the thought of living in a house in the middle of a built up area seems worse to me. Besides, bringing up kids in a flat is not child abuse, and many of these people had cheap social housing designed with families in mind pretty much handed to them, and aren't aware that in big cities this way of life is the norm for many families.
