It’s a positive outlook, but as @MajaHilton has pointed out, these units will be below minimum space standards and are therefore unlikely to be rented by the type of young professional couples that you wish to see thronging round the town centre.
Similarly I suspect that parking is hardly going to be the problem for these units. They are very close a transport hub, and single people living in rented accommodation are the least likely to have or need a car.
I can’t see anything to stop this being approved and getting some poor quality accommodation in the town centre. Don’t be surprised if the main use of these units is for temporary accommodation for single homeless people placed there by our council (or other London councils), rather than using more expensive B&B accommodation.
Rather than young couples commuting, I suspect the residents are more likely to spend their day in one of the designated spots for homeless and vulnerable people in the town centre; the underpass, outside Sainsburys, beside each cash point, and enjoying the al fresco drinking in the revamped town squares.
