I've been to Poland four times now (Krakow, Sanok, Poznan and Lublin) and you should see the houses there.
In the cities, it's all apartments. But they are spacious, modern, well appointed, with parking built under the apartment block, and with greenery and kids play areas built alongside the units. Honestly compared to our apartment blocks, it's night and day.
As soon as you move out of the city, it's houses. a lot follow the same style, detached, squarish footprint, on their own squarish plots with land around all sides. Basement at ground level or just below with garage, steps up to level 1 which has kitchen, and a couple of living rooms, stairs up to level 2 which houses bedrooms etc, and stairs up to loft space. Many houses have both gas fired and wood fired boilers, and you'll see stacks of drying wood piled in sheds and around the boundary of all the houses.
The houses are dotted around the landscape spaciously, there is no cramping together of houses into restrictive 'developments'.

In the UK how many back to back houses still exist? Pretty much none, they've been knocked down as they were unfit. Why don't we do the same with terraced runs with no parking, or un-insulatable solid wall housing? We should be modernising our housing stock and making it better, more comfortable, more spacious - we are doing the opposite.
