In practice, these three labels often describe nearly the same floor-plan concept—something larger and more flexible than a studio, but smaller (and usually cheaper) than a true one-bedroom. Still, property managers and developers use them with subtle differences:
| Term |
Typical Layout & Features |
Why Owners Use the Label |
| Convertible (a.k.a. alcove / flex) |
Oversized studio with an L-shaped or recessed sleeping alcove that can be screened off (sliding panel, curtain, bookshelf wall). Often lacks a dedicated bedroom door or exterior window.
|
Emphasizes that renters can “convert” part of the living space into a semi-private bedroom while keeping an open-plan feel if preferred.
|
| Junior 1 Bedroom |
Same footprint as a convertible but the bedroom area is already partitioned (half-height or full sliding door). May not meet legal bedroom requirements for window/closet.
|
Lets landlords market a product that feels like a “true” 1-BR without the square-footage (and cost) of a standard one-bedroom.
|
| Urban 1 Bedroom |
Rebranded junior/convertible with space-saving built-ins and upscale finishes; pitched to dense downtown markets.
|
Positions the unit as intentionally compact and lifestyle-oriented, sidestepping any “small” or “studio” stigma and supporting rents above traditional studio pricing.
|
Summary
- Interchangeable in many listings: A “junior 1 BR” is almost always a type of convertible unit; “urban 1 BR” is just a trendier label for the same thing.
- Look for clues: If the bedroom has its own door and window, it’s edging into true one-bedroom territory. If it’s open or only partially enclosed, you’re in convertible/junior land—whatever the marketing copy says.
