Short answer
Plasterboard or a traditional masonry partition?
In a period Barcelona building, plasterboard, and the reason is weight. A masonry partition adds load to a Catalan vault floor that is over a century old; a stud wall weighs a fraction of it and needs no drying time, so the programme is days rather than weeks. Traditional partitions still win where you need mass for sound or want to fix heavy items anywhere without planning it. A partition forms part of a wider layout change, quoted in writing within 48 hours of the survey — from €42/m² for a basic stud wall, €85/m² for the acoustic build-up with mineral wool and a decoupling band.
Neither system is better in the abstract. They solve different problems, and the mistake is choosing out of habit.
| Criterion | Plasterboard | Masonry partition |
|---|---|---|
| Weight on the floor structure | Very low | Significant on old floors |
| Programme | Days, no drying time | Weeks, needs setting and drying |
| Dust and disruption | Dry work, much less | Wet trade, considerable |
| Sound at equal thickness | Good only if built correctly | Better, from sheer mass |
| Hanging heavy items | Needs noggins planned in advance | Anywhere, no planning |
| Running services | Inside the void, no chasing | Chasing out required |
What decides it in Barcelona
Load. Redistributing an Eixample flat with masonry partitions means adding several tonnes to a floor built with brick vaults and steel joists. That is why dry construction is the standard here, and why a structural check comes before any layout is agreed rather than after.
Acoustics
How much sound does a stud wall really stop?
This is the expensive misunderstanding. Plasterboard can perform well or badly depending entirely on how it is built, and the cost difference between the two is small.
What makes the difference
- Mineral wool in the cavity: without it the partition is a drum
- Two layers of board each side instead of one
- Resilient perimeter band against floor, ceiling and flanking walls
- Every junction and service penetration sealed
- Socket boxes offset, never back-to-back through the same cavity
The classic failure
Single board, no wool, sockets facing each other. You hear the conversation next door as if the wall were not there. Adding wool and a second layer costs a modest amount at construction stage and transforms the result — retrofitting it later means stripping the wall you just finished decorating.
Where it matters most
Between a bedroom and a living room, and around any bathroom where a soil stack runs in the void. A stack inside an unlined, unfilled partition carries the sound of every flush through the flat, and it is the complaint we are called about most often in recent refurbishments.
For owners abroad
Fixings, permits and the owners association
Two practical matters decide whether a layout change goes smoothly, and both are settled before anyone lifts a tool.
What you can hang, and how
- Light loads — pictures, small shelves: proprietary plasterboard anchors
- Medium loads — television, bookshelves: fixed into the metal studs
- Heavy loads — wall cabinets, wall-hung sanitaryware: timber or steel noggins inside the wall, installed before it is closed
The one decision to make early
Tell us before the wall is closed where the television, the kitchen wall units or a wall-hung basin will go. A noggin is fitted and the wall will then carry anything. After it is boarded and skimmed, every solution is worse and costs more.
Permits, comunidad and derrama
Removing or adding non-structural partitions inside your flat is covered by a prior notification to the city council. The moment structure, the façade or communal elements are involved, it becomes a minor works licence with a technical project. Partitions themselves are private, so the comunidad de propietarios has nothing to approve and no derrama arises — but the administrator does set working hours, waste removal routes and whether the lift can be used, and those govern the programme.
Managing it from another country
The layout is agreed on a drawing before demolition, with noggin positions marked on it. You get weekly photographs, including shots of the open wall showing the wool, the noggins and the services before it is closed — the stage nobody can inspect afterwards.
Frequently asked
What clients ask most
In period Barcelona buildings, plasterboard: it weighs a fraction as much and adds no load to a century-old Catalan vault floor. Masonry gives more acoustic mass, but a correctly built stud wall with wool and double board comes close.
It depends entirely on how they are built. With mineral wool in the cavity, two layers of board each side and a resilient perimeter band, they perform well. With single board, no wool and back-to-back sockets, they block almost nothing — which is where their reputation comes from.
Yes, fixed into the metal studs. For wall units or wall-hung sanitaryware you need timber or steel noggins inside the wall, and those have to be installed before the wall is boarded.
Yes, using water-resistant board and proper waterproofing in the shower zone. It is the standard approach in current bathroom refits, including for recessed niches.
A prior notification covers non-structural partitions inside your own flat. If structure, the façade or communal elements are affected it becomes a minor works licence with a technical project. Working hours and lift use are agreed with the building administrator.

What we learn on site
Real housing problems in Barcelona, explained by the people who fix them.
VAT on renovations
Two invoices for the same kitchen can differ by eleven percentage points of tax without a single thing about the work having changed. What decides the rate is the building, the buyer and the proportion of materials — never the contractor.
Children and pets
Most of a renovation is compatible with family life. A handful of days are not, and they are known weeks in advance — which is exactly what makes them manageable.
Permits
Not every renovation needs a licence. Barcelona has an immediate filing for minor works, and picking the right one is the difference between starting next week and starting in two months.
