To make some generalisations about houses and internal space, one thing I've noticed is that older houses tend to have more rooms downstairs, which can be a bit jarring with modern living habits (the preference for fewer, larger, multifunctional rooms). I'd rather have a large kitchen/diner and a living room than a kitchen, a dining room, a pantry, a sitting room, a living room, and a long and wide hallway.
New build developers, on the other hand, seem to get a bit keen when it comes to bathrooms. Two-bed houses with a downstairs loo, family bathroom and en-suite to the master bedroom, and three-bed houses with a second en-suite aren't uncommon. The knock-on effect is an unnecessarily cramped upstairs layout where the bedrooms are too small for much more than a bed and basic furniture.
