Baltimore is on a surge...the fact that it is relatively short train ride away from DC area jobs and housing is way cheaper is huge plus for folks.....the whole area around the Harbor and other waterside projects, and two urban science/research parks are making it popular...even though it seems like it's population still fluctuates...
You don't have to have folks living in complete shoeboxes.....Under 400 feet is
....I understand there is demand for housing but there are plenty of spots to develop in the city without thinking you got to essentially shyt across from where you eat at ..... check this link
Transportation Division - Department of City Planning, NYC has 1,000 acres (1.5 square miles) of potential land like this inside the city....this talks about air rights which is building platforms above sunken railyards, roads....put the platform down and you put buildings on top you have just "created" land, while the roads/rails can still function normally underneath.......Plus, this is where your favorite borough Staten Island comes into play, cause a subway connection to Brooklyn would open up that area for new development, holding down/keeping steady housing cost cause supplies would be expanded.......I would hate to be a young professional and living in a double wide cubicle and calling it a home I'm paying rent for....and I've lived in studio apartments....and I know 400 feet is just about all you can stand at that size......
Besides rezoning neighborhoods for taller buildings, some of their newest developments will be created like this. This is the newest NYC air right project on the table, basically taken the Hudson Yards here......
and building something like this above it.....
That's why they calling Philly the 6th Borough............get more for your money, can still commute easily to NYC, still get that urban feel.........this is where a Maglev/REAL HIGH SPEED trains come in real handy
@ living in a 275 sq ft apartment. Might as well live in a cage.
...probably me....but I try to avoid westheimer at all cause...had a bad accident on that road....
