The 3BR/2BA is the suburban-comfort apartment: enough bedrooms for a family, enough baths to avoid morning queues, and enough living area to host. It is the most-built family apartment in many North American and Australian markets, and is the configuration where 'master suite' logic starts to genuinely apply.
How this generator works
Six templates: corridor (linear), master-wing (master + ensuite separated from secondary bedrooms by the public zone), split (two clusters separated by living), lshape (L-shaped envelope), deep (deep rectangular envelope), and open (open kitchen layout). Master-wing is the highest-value template because it physically separates the master from secondary bedrooms, which improves acoustic and visual privacy in a way that a corridor adjacency cannot. The master bathroom is always implemented as ensuite — accessible only through the master bedroom — and the second bath is placed on the corridor between BR2 and BR3.
Design principles for 3BR/2BA
Master bedroom 12–18 m² (largest), secondary bedrooms 9–13 m². Master bath 4–7 m² (typically with shower-only at the low end, full tub at the high end), shared bath 4–6 m². Living room 18–32 m², kitchen 7–11 m². The total private area (3 bedrooms + 2 baths) sits at 38–60 m²; the public area at 25–45 m². The master-bath plumbing wall runs adjacent to the second-bath plumbing wall whenever possible to consolidate plumbing risers — this is generated automatically in the corridor and master-wing templates.
When 3BR/2BA works best
Mid-size families, couples with frequent guests, work-from-home households where one bedroom doubles as an office, and aging-in-place planning where the master is the wheelchair-accessible suite. It is an oversize for a single occupant or a couple without children; below ~85 m² it starts feeling like a 2BR with a converted study.
Configuration tips
Master-wing template at 90+ m² creates real privacy worth paying for. Open kitchen flips to default at 100+ m² because you have enough public-zone area to absorb the visual dominance of the kitchen. A balcony off the living room is standard; a master-bedroom balcony is the upmarket variant and is worth 5–7 m² off the master.
Frequently asked questions
What is a master suite in a 3BR/2BA layout?+
A master suite is the master bedroom plus its ensuite bathroom plus, optionally, a walk-in closet. In a 3BR/2BA, the master gets the ensuite and the second bath serves the two secondary bedrooms via the corridor. The master-wing template separates the suite from the secondary bedrooms by placing the public zone between them.
Why does the master-wing template improve privacy?+
Acoustic and visual privacy in apartments come from physical separation, not just doors. The master-wing template puts the public zone (living + kitchen) between the master and the secondary bedrooms, so the master is not adjacent to children's rooms or guest rooms across a corridor.
How big should the master bedroom be relative to secondary bedrooms?+
Master 12–18 m², secondary 9–13 m². The 3–5 m² delta lets the master accommodate a king bed plus an armchair or dressing area, while secondary bedrooms remain comfortable for single or double beds without becoming over-sized for their function.
Can I have a balcony off the master bedroom?+
The balcony toggle places a single balcony off the living room by default. A master-bedroom balcony is plausible at 100+ m² total area but trades 5–7 m² off the master's interior — a real trade-off that the generator does not model directly. The balcony location can be edited in the exported SVG.
