I think that selling a house based solely on number of bedrooms is stupid. All it does is encourage developers to squeeze as many bedrooms into a house as possible, so you end up with a 3 metre X 3 metre master bedroom that has no built-in wardrobe, and no place to put one because there's one door for the 'en suite' and another for the entrance to the room, and a large window. And all the other bedrooms are even smaller.
Apartments, multi-family houses, and housing blocks are much more common in many other countries than the UK. IMO, among the reasons it is so difficult to get on the property ladder in the UK are:
-everyone believes they need to own a detached house
-few multi-unit houses and buildings are built with families in mind
So, a single person or a couple trying to get onto the property ladder can buy an apartment, but a family cannot, at least not easily outside of London. If they do find an apartment big enough, it is unlikely to include family amenities such as a playground. There may not be ground floor storage for buggies or prams, or a lift to take them to the 1st floor, etc.
In every other European country I have been in, apartment buildings and multi-family houses are built, at least in some part, with families in mind. In the Netherlands, Sweden, Norway and other countries, apartment buildings, multi-family houses, and even detached and semi-detached units are often built around a common play area, so that children can go out and play independently from a young age at varying levels of supervision. In Germany and Italy, most apartment complexes have a variety of units, ranging from 25 square metre studio apartments to a 250 square metre 4 bedroom apartments.
