It's another sad half-measure.
Cramming more matchstick shoeboxes into the backyard isn't going to make enough of a dent: instead of putting 4 more miniature townhouses back there, bulldoze the lot until it's contiguous and put up another tower.
Bungalows are ancient history; a fad from a by-gone picket-fence boomer era. We need the parkland back and we need the housing; and the only way we'll get both is by ensuring all housing is dense a-f so we can reserve for shared green-space.
Let's stop messing around.
