It's a shame most new build apartments ins SF are so horribly designed. 900-sqft is enough for a comfortable 3 bedroom apartment. In an SF new build it probably means a deep, dark open plan space with windows on only one small wall.
My 1BR is around 900 sq ft, and I'm having trouble envisioning how you'd carve two more bedrooms out of it and still have a nice space. One more bedroom, sure, but two more feels like it would be a stretch.
Gives me kinda different perspective on the poverty of everyday Soviet living, eh. It's slowly changing for the better, though.
It seems the average house in the USA is over twice the size of the average house in the UK [1], and is significantly larger than many countries.
