Interior Layout: Fitting a Bedroom, Balcony and Wet/Dry Bathroom into 13 m²

Thirteen square metres sounds like a limitation until you see how it is organised. In this format, internal area is allocated across three functional zones: a bedroom, a balcony, and a wet/dry separated bathroom. Occupancy is stated as one to two people.

The design question is not how much space exists but how the zones are separated, because separation is what makes a small space feel usable rather than merely small.

External dimensions set the internal geometry. Published dimensions are 5.8 m long, 2.25 m wide and 2.45 m high. The length is what allows three zones to sit in sequence, while the width constrains circulation: with roughly two metres of internal width, furniture has to be placed along the walls and the central path kept clear.

This is why the layout is longitudinal rather than centralised, and why specifying furniture dimensions matters more here than in a conventionally sized room.

The wet/dry bathroom split. Separating wet and dry areas in a compact bathroom is a functional decision, not a stylistic one. It keeps the shower's water and humidity away from the mirror, vanity and storage, which slows deterioration of the fit-out and reduces the cleaning burden between guests. In a unit used for short-stay accommodation, that directly affects turnaround time.

The bathroom module typically includes a toilet, sink, smart mirror and vanity cabinet.

The balcony, and why it changes the product. The balcony is the element that distinguishes this format from a compact room. Combined with the full-height glazing, it extends the usable experience beyond the internal area: the unit is not only a place to sleep but a place to sit and look outward.

For accommodation projects this is commercially significant, because it is what guests photograph and describe. Practically, it also means the glazing and the balcony structure need to be considered together in the structural and thermal design rather than treated as separate items.

What the base fit-out covers. The base specification typically covers wall, floor and ceiling finishing, plus the functional systems for heat insulation, waterproofing and windproofing. Access control is handled by a smart lock, and an integrated smart home control system manages lighting and core electrical functions.

Hydropower infrastructure includes indoor and outdoor lighting circuits, code-compliant wiring, and a sewerage system paired with a water treatment arrangement. In other words, the shell arrives habitable in a technical sense; what remains is the question of what it is habitable for.

Optional modules change the use case. Two modules materially change how the unit functions. A kitchen module adds an induction cooktop, upper and lower cabinetry, a sink and artificial stone countertops. A bathroom upgrade adds the fixtures described above.

A furniture package covering sofa, coffee table, television cabinet, double bed and appliances takes the unit to the point of functioning as a residence, a guest house or a rental unit immediately on delivery. For an operator, the decision to include a kitchen is the decision that determines whether the unit can support longer stays or only overnight bookings.

Planning implications worth noting early. Three. First, whether units will be used for overnight stays or multi-night self-catering determines the required module set, and retrofitting a kitchen later is more disruptive than ordering it. Second, the glazed wall drives both guest appeal and thermal load, so shading and curtain specification should be decided with the layout, not after it.

Third, the longitudinal layout makes the unit highly sensitive to orientation on site: which direction the glazing faces determines whether the balcony is usable at the times guests actually occupy it.
