In a small flat, the problem is rarely just the square metres. What makes the difference is how they are laid out. We’ve seen 45 m² flats that work with impeccable clarity and others of 70 m² that feel fragmented, dark or full of useless corridors. That’s why, when we talk about the best layouts for small flats, we’re not talking about a one-size-fits-all formula, but rather about precise decisions regarding circulation, light, storage and spatial hierarchy.
A good layout isn’t about cramming in more elements. It’s about making the home easier to navigate, more functional and a place where daily life flows more smoothly. In city flats, where every centimetre counts, this requires looking at the space from an architectural perspective, not just a decorative one.
What defines the best layouts for small flats
There is one misconception that needs to be dispelled from the outset: opening everything up is not always the best solution. An open-plan layout can provide visual spaciousness, yes, but it can also leave you without privacy, without storage and without truly comfortable areas. The best layout is one that responds to a specific way of living.
When undertaking a residential refurbishment, we usually start by considering three things: where the light comes in, how the flow of movement is organised, and which rooms need priority. From there, the layout begins to take shape. If the living room faces the best aspect, it makes sense to preserve that position. If the flat is deep and narrow, it might be best to open up the central axis. If the home is occupied by a single person, different functional areas can be merged; if shared by two or more people, the transitions between spaces become more important.
A sense of spaciousness doesn’t just depend on removing partition walls. It also depends on avoiding wasted corners, doors facing each other, oversized furniture and circulation routes that disrupt visual continuity. A small flat works best when each area has a clear purpose and a logical relationship with the others.
Layouts that tend to work best
Compact living area and cosy sleeping area
This is one of the most effective solutions for flats with limited floor space. Grouping the living room, dining room and kitchen into a single open-plan area frees up space and improves natural light. The sleeping area is more secluded, even if it is compact, and feels tidier.
This layout works particularly well when the flat has an attractive main façade and a darker interior. The key is not to turn the communal area into an ambiguous space. The kitchen, living room and dining area can coexist, but they need a clear structure: a small island, a table aligned with the kitchen or a long piece of furniture to organise the whole space.
Concentrated utility area
When the bathroom, kitchen, utility room and service installations are grouped together in a single strip, the rest of the flat feels more open and flexible. This approach reduces the length of service runs, simplifies the building work and allows the best locations to be reserved for the living spaces.
In older flats in Barcelona, a useful pattern often emerges: moving wet areas inwards and reclaiming the façade for the main living areas. This isn’t always possible, as it depends on drainage pipes, the building’s structure and regulations, but when it works, the difference is striking. The flat gains a sense of continuity and the light works to the benefit of the whole space.
Hybrid spaces with controlled separation
Not all bedrooms need to be completely enclosed, nor do all studies have to remain open at all times. In small flats, partial partitions – glass partitions, sliding panels, flush doors or room-dividing furniture – allow the degree of openness to be adjusted according to use.
It’s a useful solution for single-person households or couples who prioritise spaciousness during the day. The benefit is clear: the space feels larger and more flexible. There’s a downside, too: less sound insulation and a more exposed living environment. That’s why this type of layout only works well when it truly suits the user’s lifestyle.
The silent enemy: the hallway
In many small homes, the hallway takes up more space than it appears to. It doesn’t just take up floor space; it also blocks natural light, forces the installation of multiple doors and fragments the overall feel of the flat.
Reducing its size or integrating it is often one of the most worthwhile decisions in a renovation. Sometimes it is enough simply to incorporate it into the living area. At other times, it is transformed into continuous storage, a library, a utility cupboard or a bench. The aim is not to eliminate all transitions, but to prevent that transition from becoming a dead space.
When the hallway disappears, the flat not only gains usable space but also becomes more intuitive. It is easier to understand, easier to navigate and feels more spacious.
Open-plan, semi-open or closed kitchen
This point deserves a less automatic approach. The open-plan kitchen has become almost standard in small flats, and with good reason: it improves social interaction, lightens the floor plan and draws in natural light. But it is not always the best option.
If you cook a lot, if visual order is particularly important, or if the living room is very small, a semi-open kitchen usually works better. A light partition, a sliding door or a generous yet defined opening allow you to maintain a connection without exposing everything.
A closed-off kitchen, on the other hand, only makes sense when the flat has sufficient floor space or when the original layout fully justifies it. In a small flat, compartmentalising the space without a compelling reason tends to detract from the spatial experience.
Built-in storage: part of the layout, not the furniture
One of the most common mistakes in small flats is leaving storage until last. When it’s left until later, you end up with makeshift cupboards, freestanding units and items that obstruct the flow of movement. At that point, the problem is no longer a lack of space, but a lack of strategy.
The best layouts for small flats incorporate storage from the outset. A cupboard can define an entrance, separate a bedroom, conceal utilities or visually extend a wall. A bench can provide storage whilst also keeping the living area tidy. A bespoke headboard can replace bedside tables, chests of drawers and freestanding shelves.
When storage is integrated into the architecture, the flat appears tidier and more spacious. Not by magic, but because visual clutter disappears.
Light, structure and proportion
Not all desirable layouts are feasible. There are constraints that dictate the design: load-bearing walls, columns, courtyards, drainpipes, façade openings and headroom. Designing a small flat well requires accepting these rules and working with them, not against them.
The structure can serve as a guide. An isolated column can help to divide the space into zones. An existing wall can provide support for a storage unit. A small courtyard can justify a well-designed internal bathroom and free up the main living areas to let in light.
Proportion matters too. A small but well-proportioned space feels better than a larger, clumsy one. That is why it is advisable to adjust passage widths, avoid tiny rooms with no room for manoeuvre, and plan each room with actual furniture in mind, rather than abstract layouts.
A common scenario: renovating a compartmentalised flat
There is a situation we often encounter: flats with many small rooms, an isolated kitchen, a long corridor and a living room that lacks character. On paper, they appear to have several rooms. In practice, they feel cramped and dark.
The most effective approach is not usually to demolish indiscriminately, but to be selective. The living area is opened up, utility spaces are consolidated, the number of doors is reduced, and a clear visual axis from the entrance is emphasised. The master bedroom feels more peaceful. The bathroom integrates better with the rest of the flat. And the whole home takes on a more contemporary feel without losing its character.
That balance is important. A small flat doesn’t have to look generic to work well. It can retain original features, texture, rhythm or materials with character, provided the layout no longer gets in the way of everyday life.
What to decide before renovating
Before moving a partition wall, there are questions that can greatly refine the outcome. Do you work from home every day or only occasionally? Do you entertain guests frequently? Do you need plenty of hidden storage, or do you prefer a more open and visually uncluttered home? Is the priority to let the property, live there long-term or increase its value?
The answer shapes the layout. An investor doesn’t need the same things as a couple planning to stay for years. A professional working from home needs smooth transitions, good acoustics and functional support. A holiday let or a property for occasional use allows for more radical decisions; a main residence demands greater durability for everyday life.
This is where a bespoke design makes all the difference. It’s not about following a trend, but about tailoring the floor plan to a real way of living.
Designing a small flat well is an exercise in precision. Fewer square metres force you to make better decisions, not to compromise on quality. When the layout is well thought out, the home gains a sense of space, order and value without the need for excess. And that is, ultimately, the true luxury in a compact space.
