How to lay out a small flat to gain space: practical guide for Cádiz

Why layout matters more than square footage
A well-laid-out 55-square-metre flat can feel far more comfortable and functional than an 80-square-metre one with an endless corridor and poorly proportioned rooms. In Cádiz we see this all the time: flats in the old town with thick walls that eat into usable space, or properties in Puerta Tierra with 1960s layouts that waste metres on thoroughfares going nowhere. The key isn't having more space, it's making every single square metre work for you.
Knowing how to lay out a small flat is the difference between living cramped and living with room to breathe. When you reconfigure the rooms in a small flat, you don't just gain usable floor area, you also improve the natural flow, the amount of light coming in, and the overall sense of space. It's one of the highest-return renovations you can do, because it transforms your everyday experience without needing to upsize to a larger, more expensive property.
In our experience renovating flats across Cádiz city, Chiclana, San Fernando, and El Puerto de Santa María, we've found that a well-thought-out reconfiguration can give a small flat between 15% and 25% more usable space. It's not magic, it's careful planning, a solid understanding of local regulations, and design solutions tailored to the architecture of the Cádiz region.
Read your floor plan: the most common layout mistakes in Cádiz flats
Before you knock anything down, you need to understand what's actually wrong with your current layout. Get hold of your floor plan (or request it from the Catastro) and work out where the space is being lost. In typical Cádiz flats, certain patterns repeat themselves time and again, particularly in buildings put up between the 1950s and 1980s, when the priority was to partition everything to the maximum without a second thought for how people actually live.
- Long, narrow corridors taking up between 4 and 8 m² without serving any purpose beyond getting from A to B.
- Closed-off, poky kitchens (5–6 m²) separated from the living room by a wall that serves no real purpose.
- Long, thin living rooms with a single window at the far end, leaving half the room in near-darkness.
- Bedrooms with doors facing one another, creating dead corners that are impossible to furnish.
- Oversized entrance halls in flats where every metre counts.
- Bathrooms with full-size baths in flats under 60 m², where a shower tray would free up valuable space.
The layout of a small flat in Cádiz is also shaped by the load-bearing walls, which in older buildings in the historic centre are often made of ostionera stone and can be anywhere between 40 and 60 cm thick. Identifying them before you start planning is essential: a qualified surveyor will tell you which are structural and which are simple brick partition walls you can remove without any structural concerns. Skipping this step can cost you dearly.
Removing or moving walls: when it's worth it and what it costs
Knocking down a partition wall to gain space is probably the single action with the greatest visual and functional impact in a small flat renovation. But it isn't always feasible, or even necessary. The rule of thumb is straightforward: if the wall is a partition (single or double hollow brick, 7–10 cm thick), it can generally be removed without any structural complications. If it's a load-bearing wall, you'll need a structural assessment and, in most cases, a reinforcing steel beam (IPN or HEB), which pushes the cost up considerably.
| Type of work | Approximate cost (€) | Estimated timescale | Permits required |
|---|---|---|---|
| Removing a simple partition wall | €300–€600 | 1 day | Prior notification to the Ayuntamiento |
| Removing a wall to open the kitchen to the living room | €1,200–€2,500 | 3 – 5 days | Prior notification + electrical certificate |
| Removing a load-bearing wall with IPN beam | €2,500–€5,000 | 5 – 10 days | Minor works licence + technical project |
| Moving a partition wall to reconfigure rooms | €800–€1,800 | 2 – 4 days | Prior notification |
| Combining two small rooms into one | €1,000–€2,200 | 3 – 5 days | Prior notification |
In Cádiz, prior notification of works is processed at the Ayuntamiento and is typically resolved within 15 working days. For work that affects the structure, you'll need a minor works licence and a project signed off by a qualified architect, with an additional cost of between €400 and €900 for the project itself. We handle all of this paperwork on your behalf, so you don't have to deal with the bureaucracy.
Professional tip: before knocking down any wall, check whether any services run through it, water pipes, drainage, or electrical cabling. Relocating these can add between €200 and €800 to the budget. A plumber and an electrician should inspect the area before the sledgehammer comes out.
Open-plan vs. divided spaces: how to decide
Opening the kitchen onto the living room in Cádiz has become the go-to renovation for small flats, and with good reason: removing that wall between the kitchen and living room can add between 3 and 6 square metres of perceived space. But open-plan isn't the universal answer. If you cook regularly with plenty of frying, if you need privacy to work from home, or if you share the flat with people on different schedules, keeping certain areas divided still makes a great deal of sense.
The middle ground that works best in small flats is the semi-open concept: remove the wall entirely but install a breakfast bar or kitchen island that visually separates the kitchen from the living area, or use sliding glass doors that fold back completely when you want an open feel and close off when you need to contain cooking smells or noise. A pocket sliding door built into the wall takes up zero space and costs between €350 and €700 fitted.
When deciding how to make the most of your small flat's space, think about how you actually live, not how it looks in a magazine. An open-plan kitchen and living room looks stunning in photos, but if it doesn't suit your daily routine, you'll end up regretting it. We always do an initial visit to understand how you use your home before proposing a layout.
Bespoke furniture and storage solutions that multiply your space
In a small flat, every centimetre counts, and off-the-shelf furniture rarely makes the most of the space available. Bespoke fitted furniture for a small flat in Cádiz allows you to cover entire walls from floor to ceiling, make use of awkward corners, and create storage where previously there was nothing but dead air. A made-to-measure fitted wardrobe costs between €600 and €1,500 per linear metre, but delivers twice the value of a freestanding unit because it fits your home's exact dimensions and layout.
- Floor-to-ceiling fitted wardrobes with a personalised interior: make full use of the height typical in Cádiz flats (usually 2.50–2.70 m).
- Beds with Ottoman storage or under-bed drawers: create between 1.5 and 2 m³ of extra storage without taking up any additional floor space.
- Floating shelves and high-level wall storage: free up the floor and give the room a more open feel.
- Bespoke living room units combining TV space, shelving, and closed storage: one integrated piece in place of three separate bits of furniture.
- Mezzanines and raised sleeping areas in flats with high ceilings (common in Cádiz's historic centre, where ceiling heights of 3–3.5 m are not unusual).
- Pull-out shoe racks, under-stair drawers, and kitchen units fitted with organiser accessories.
Smart storage in a small flat isn't just about fitting more things in, it's about everything having a proper place and being easy to get to. A common mistake is accumulating storage furniture that ends up blocking the flow of movement. The golden rule is that storage should be vertical (use the walls) and concealed (doors, drawers, flush fronts) to maintain the visual calm that allows a small space to breathe.
Lighting and colour: how to make a small flat feel bigger
Natural light is the greatest ally when it comes to making the most of a flat in Cádiz, and the city treats us to more than 3,000 hours of sunshine a year. Make the most of it: don't block windows with tall furniture, swap heavy curtains for translucent roller blinds, and if possible, enlarge the window frames as part of the renovation. A trick we use regularly is to position mirrors opposite windows to effectively double the natural light flooding into the room.
When it comes to artificial lighting, ditch the single central pendant: it flattens the space and creates harsh shadows. What works in small flats is layered lighting, general illumination with recessed LED downlights (installation cost: €15–25 per point), ambient lighting with LED strip lights on shelving or under kitchen units, and task lighting with table lamps or wall-mounted fittings. This approach costs between €400 and €900 for an entire flat and completely transforms how the space feels.
Colour plays a fundamental role as well. Light tones (off-white, warm beige, pearl grey) open up any room visually. But that doesn't mean everything has to look like a hospital: you can paint one feature wall in a deeper shade to add depth without making the room feel smaller. In Cádiz, sandy tones, dusty blue, and sage green all connect beautifully with the local surroundings and bring warmth without closing the space in. A quality tin of paint costs between €30 and €60, and painting an entire 50–60 m² flat comes to around €800–1,200 including labour.
Smart layouts for each room: living room, kitchen, and bedroom
In the living room of a small flat, an L-shaped arrangement makes better use of corners than a sofa pushed straight against a wall. If the living room is under 15 m², opt for a two-seater sofa (no more than 180 cm) and a side table rather than a bulky coffee table. Consider a wall-mounted TV unit that frees up the floor, it adds to the sense of space. If you've opened the kitchen onto the living room, a breakfast bar or island doubles as an informal dining table and removes the need for a separate one that would only eat into your space.
For rethinking the kitchen in a small flat, an L-shaped or single-wall (galley) layout makes the best use of the available space. The key is to respect the work triangle: the sink, hob, and fridge should all be within easy reach of one another. If the kitchen is under 6 m², go for standard 60 cm-deep worktops, wall units that run all the way to the ceiling, and integrated appliances. A fully renovated bespoke kitchen in Cádiz starts at around €4,500 and can reach €8,000–10,000 for mid-to-high-end finishes.
The master bedroom in a small flat should prioritise the bed and storage, nothing else. If the room is under 9 m², consider a 135 cm bed rather than a 150 cm one: those 15 centimetres free up room for bedside tables or a small desk. Fitted wardrobes with sliding doors (rather than hinged) save the space needed to swing the doors open, in a small bedroom, that can be the difference between moving around comfortably and clipping the door every morning.
Indicative costs for reconfiguring a small flat in Cádiz
The cost of renovating a small flat in Cádiz to improve its layout varies depending on the scope of the work. Below is a table with realistic price ranges based on our recent projects, to give you a clear idea before requesting a quote.
| Scope of renovation | Typical size | Price range (€) | Estimated duration |
|---|---|---|---|
| Basic reconfiguration (remove 1–2 partition walls, paint, adjust electrics) | 45 – 60 m² | €3,000–€6,000 | 2 – 3 weeks |
| Mid-range reconfiguration (open kitchen, relocate bathroom, bespoke furniture) | 45 – 60 m² | €8,000–€15,000 | 4 – 6 weeks |
| Full renovation with complete reconfiguration | 45 – 60 m² | €18,000–€30,000 | 8 – 12 weeks |
| New open-plan kitchen into living room (furniture + building work) | 10 – 14 m² | €6,000–€12,000 | 3 – 5 weeks |
| Bespoke fitted wardrobes (2–3 units) | — | €2,000–€5,000 | 1 – 2 weeks |
These prices include materials, labour, and waste disposal, but do not cover council permits or technical fees (where applicable). In Cádiz, VAT on renovations to a main residence is charged at the reduced rate of 10%, which represents a significant saving compared to the standard 21%. We'd recommend getting at least two itemised quotes so you can make a proper comparison.
