The only first floor GV is the HA one in building 48. There are also 2 GVs in building 63 that will have elevator access, but one of those is also HA. I'm old now, but I don't ever recall being 7 months pregnant making me feel like I needed a handicapped accessible unit. I was able to walk up one floor easily well into my 9th month, and I had a 10 and a half pound baby the last time. I'm quite sure the inconvenience of the low counters, and handicapped showers and lack of a tub would be far worse than walking up one flight of stairs. Also, unless you plan to give the master suite to the pregnant one, they will still have to walk upstairs inside the unit to the other bedrooms.
