Multi-unit residential architecture has made some minor advances in the past few decades. Developers tend to focus on interior amenities like in-suite laundry closets and logical floor plans. Accessibility codes mandate well proportioned bathrooms and energy codes guarantee a comfortable indoor temperature.
Exterior treatments are another matter. Cheap windows and siding materials are the rule, and architects are asked to mitigate this obvious poverty with pointless massing and flashy colors. Monotonous grids are frowned upon except in luxury high-rises.
