The mismatch in floor heights is something I also find jarring. The changes in standards mean that floor heights are reducing, leading to this. It'd have cost them more to build matching floor heights and they might have had to have one storey less to get planning permission. Something similar happened near where I lived in London. Developers got permission to build an apartment block on condition that it looked the same as its older neighbour. The result was an odd looking mini version, about 2 metres shorter than the original.
