The two rehearsal rooms of this Brazilian music school are covered with chalkboards on the outside and oriented strand board on the inside.

Designed by architects 0E1, the Eclética Centro De Música centres around an informal foyer where students and teachers are able to make notes on the walls.

This space separates the two practice rooms and leads into a recital room beyond.

OSB was also used to make stools and tables for every room plus some bookshelves slotted into one corner.

Here's some more information from 0E1:

The design for this music school is based upon the creation of two hermetic chambers to house rehearsals inside a large space in a historic building located in Nova Prata, Brasil. The configuration of such boxes turns the residual space into two ambients that, even though are continuous, configure different spaces for different activities.

The proposal aims to enrich the user’s experience while using the as little compositive elements as possible.

When entering the school, one arrives at a foyer located between two chambers, where the administration and reception are; going further inside the school, a new space emerges, where students can practice before and after class, interacting and sharing knowledge.

The interior of the chambers was designed in order to optimize the acoustics and the comfort of the users. The lighting solution maintains the 3,4-meter-high ceiling and creates a lower light surface, increasing the comfort without losing the acoustic properties of the original building.

A series of furniture were designed to meet the overall resource economy of the project. The material used in the furnishing is the same OSB that covers the interior of the chambers, assuring unity to the design. The different models satisfy the different users’ needs, from instrument practice to administrative functions.
