How much does it cost to build a drywall wall?

I've already put up drywall at home and the cost really depends on the size, whether it's basic or with insulation, and local labor rates - but figure roughly 15 to 25 euros per square meter, maybe a bit less if you do it yourself.

Do you mean an entire wall or a small partition? The price varies quite a bit depending on the size, whether you need special finishes, and what region you're in, but generally it's around 30 to 50 euros per square meter for labor, not including materials. If it's complete professional work (boards, framing, cutouts, painting), it can go up to 80-100 euros/m² or more, whereas if you do the board installation yourself and just hire basic labor, it comes out much cheaper. Best thing is to get quotes from local companies, since they'll calculate costs based on your specific project.

The price varies too much to give you a fixed number, but yeah, that's really it - material plus labor add up quite a bit. Here in Brazil you're looking at something between 80 to 150 reais per square meter if it's just the plate and basic structure, but it goes up to 200+ if you include acoustic or thermal insulation. People don't mention that it changes a lot depending on the region and the worker you hire.

What nobody talks about is that if you have a bit of patience and help with the installation (or do it yourself if it's not a structural wall), you can save a lot. Like, taking responsibility for bringing the plates, marking the outlet points and holes reduces the professional's quote. It's also worth buying material directly from a construction supply store instead of hiring someone who already includes everything in the price - it works out cheaper.

Another thing: if the wall is temporary or you want to change it later, drywall is perfect for that exact reason, but the upfront investment might seem high if you're comparing it to regular brickwork. If it's a small partition wall, the fixed cost of the professional's travel and setup ends up weighing more on the per-square-meter cost.

When I built a drywall partition here at home, the quote came in at somewhere between 90 and 120 reais per square meter, but that was without soundproofing - if you want something more reinforced the price goes up quite a bit. It really does vary a lot depending on the region, whether the wall is single or double-sided, and especially whether you hire a professional or do it yourself on a budget 😅 My tip is to get quotes from at least two local suppliers, because people who work with this stuff tend to have pretty different pricing.
