Studio vs 1-bedroom: which fits your needs

A studio at 40 m² and a 1-bedroom at 45 m² look almost identical on a price-per-m² basis, but they live very differently. The 5 m² delta is the cost of one wall, one door, and a bedroom small enough that no human-sized bed fits comfortably. Whether that wall is worth the rent premium depends on a question that has nothing to do with area: how much you mind your sleep space being visible from your kitchen.

What the bedroom wall actually does

An enclosed bedroom does three things a studio cannot. First, it gives you a place where the bed is the room — somewhere to retreat without dragging a duvet across the kitchen counter. Second, it lets you keep the rest of the apartment visible to a guest without compromising your privacy: leaving the bedroom door closed lets the studio function as a small living room. Third, it provides a real acoustic barrier for sleep. A bedroom door, even a hollow-core one, attenuates kitchen and street noise by 20–25 dB; an open studio just doesn't.

Against those benefits is the cost: one full wall (2.4–3.0 m × ~2.7 m, plus a door), a swing zone for the door, and a bedroom that's typically 7–11 m² — the smallest room in the home. In a 45 m² 1BR, the bedroom is around 9 m² and the rest of the apartment (living, kitchen, bath, hall) shares 36 m². In a 45 m² studio, the bath is still around 4 m² but you have a full 41 m² of open living space.

When a studio is the better choice

Studios work well for single-occupant living without intensive work-from-home, short-stay rentals, and any situation where you would rather have one larger space than a small bedroom plus a small living. The acoustic and privacy compromises matter less when you live alone and host rarely. Studios are also the right call below 30 m²: a 1BR at 28 m² has a 6 m² bedroom that doesn't fit a queen bed with a nightstand, and the trade isn't worth it.

Studios also tend to feel larger than their plan suggests because the same area unbroken by a wall reads as a single envelope. A 35 m² studio feels like a small apartment; a 35 m² 1BR feels like two cramped rooms.

When a 1-bedroom is the better choice

Choose a 1BR when any of these apply: two people will live there with overlapping schedules, you work from home and need to leave the work area visually separate from the sleep area, you frequently host guests overnight, or you sleep at unusual hours and need acoustic isolation from a partner. Above 50 m², the 1BR's bedroom-wall cost is a smaller fraction of total area and the trade tilts toward 1BR.

Resale and rental value also typically favour 1BRs at the same area — the market generally pays a small premium for the wall. But the premium is small enough (5–10%) that it should not drive the choice if you genuinely prefer the studio's spatial logic.

The middle ground: studio with bed alcove

Above 40 m², studio plans on this site can produce a bed alcove — a half-wall or an L-shaped envelope that suggests separation without committing to it. This is genuinely useful: you keep most of the studio's open spatial logic, gain a bit of bedroom acoustic shelter, and avoid the small-bedroom-plus-small-living awkwardness of a 1BR at the same area. It is also not represented well on a 2D plan — the alcove looks like an open room, but in the built version it can have a partial wall, a curtain, or a half-height divider.

Quick rule of thumb

Below 30 m², always studio (the bedroom is too small to be useful). 30–45 m², depends on use case (single-occupant + low WFH = studio, two-occupant or heavy WFH = 1BR). 45–60 m², 1BR is usually the better envelope. Above 60 m², 1BR is almost always the right call — at that size the bedroom is comfortable and the rest of the apartment still has plenty of room. If you can't decide, generate both at the area you're considering and look at them side by side.
