Updated budget for 2025 shows that a 4 x 4 meter room, with 16 m², slab, built-in roof, painted door and window, can reach R$ 20,000 including materials and labor.
Building a 4 x 4 meter room, with 16 m², can cost R$ 20,000 including materials and labor, according to the updated budget for 2026. The amount considers a project with a slab, built-in roof, already painted door and window, as well as a structure prepared with 5/16 iron.
In the survey presented by the channel Do André Filipe, the cost of materials was R$ 12,000. The labor for the bricklayer was estimated at R$ 8,000, with the room delivered finished. The budget aims to provide a close reference for those planning to build.
How much does it cost to build a 4 x 4 room
The room considered in the calculation is 4 meters wide by 4 meters long. The proposal does not follow an economical model, as it includes a slab and a more reinforced structure to support this type of construction.

The planned window measures 2 meters by 1 meter and is already painted. The door was also considered in a finished version, already with paint. These items are part of the standard used in the presented budget.
Materials and bricklayer weigh on the budget
To build a room to this standard, materials represent the largest part of the expense, reaching R$ 12,000. The bricklayer would charge around R$ 8,000 to perform the service and deliver the room ready.
The total of R$ 20,000 may vary slightly up or down, as it is a summarized budget. The reference considers updated values and possible increases in construction materials.
Model with slab is not the cheapest
The mentioned room was designed with a built-in roof and slab, which makes the structure more complete. It was also mentioned that a more economical version, without a slab, could have a lower cost.
Even so, for those who wish to build a 16 m² room to this standard, the final estimate between materials and bricklayer was R$ 20,000.
