Also, if you're being serious about energy efficiency, you can exploit larger windows for some thermal gain from sunlight coming through them in the winter (and the ones on that block are facing roughly south are they not). Of course, you have to make some effort to get things right for this to work, which could mean more expense, say from creating summer shading, and I'd guess that's an expense they didn't want to think about here. So make a gesture at energy efficiency for your sales propaganda, at the expense of the quality of life of the people that are going to have to live in there. This stuff is quite damaging to the overall development of genuinely more energy-efficient building, because people say stuff like "oh yeah, so-and-so lives in an energy efficient flat but the windows are tiny and it's like a prison".
I should say that I don't know anything in detail about this particular development and most of the above is based on supposition. Happy to be corrected by anyone who knows more about it.
