In 2018 Rotor was contacted by the municipality of Dilbeek to intervene in the festival "De Blik van Breugel" celebrating the 450th anniversary of the death of the famous painter Pierre Breugel, in Itterbeek, on the outskirts of Brussels. This festival took place from the beginning of April to the end of October 2019.
Rotor was contacted to design the pavilion for the festival (more information about the pavilion). This project was the perfect opportunity for the commune to highlight the use of reused materials.
It turned out that the municipality of Dilbeek was planning to build, at the same time, a new sanitary block for the members of the Chiro d'Itterbeek (youth organization), their premises being located in an old L-shaped farmhouse in the center of Itterbeek, right in front of the small church of Sint-Anna-Pede. This project could be perfectly combined with the need to provide sanitary facilities for the visitors of the festival 'De Blik van Breugel'. So a second assignment - the construction of a sanitary block next to the old farmhouse - came to Rotor. During the design phase, we proposed to the municipality of Dilbeek that we develop an exemplary project in which we would use a maximum of reusable building materials. In terms of tendering, this resulted in a design and construction contract for Rotor as designer-contractor, in association with the company CC Autrement. Little is known about the history of the farm where the toilet block was built. The building itself is the property of the Itterbeek church administration, which makes it available to the Chiro of Itterbeek. The sanitary block is the property of the municipality of Dilbeek.
This small building project is therefore an extension of the existing farmhouse, which, although completely new, consists of less than a third of new materials (in % mass). The majority of the materials are, on the one hand, materials recovered from various Belgian operators and, on the other hand, surplus from construction sites.
The facade, for example, is entirely made of bricks and joinery of reuse. The interior of the sanitary block is mainly made of reused materials sold by RotorDC. For example, the floor covering is made of ceramic tiles from a former Everheide elementary school (Brussels region) dating from the 1930s. The sanitary appliances (urinals, toilets and suspended washbasins), the lighting and the mirrors were also recovered, before finding their new destination in this project. The load-bearing structure, both the concrete blocks and the framework and associated thermal insulation, came from site surplus or surplus production. The tiles are surplus from the renovation of a villa in Brussels.
The scale of this project is modest but all the phases of a classic new construction project were carried out (foundations, sewers, shell, plumbing, electricity and interior design). The ambition to work as much as possible with reused materials was therefore explored at all levels. The objective of this small project was to show what is possible to implement and, at the same time, to identify the main logistical and organizational obstacles that can hinder material reuse projects. In this sense, the project was also an important learning experience for all involved.
If you had to do it again?
The construction site went well because the communication between the participants was fluid and easy. The question of materials was carefully thought out beforehand in order to try to use as many reused materials as possible while avoiding the need for the construction company to go and find materials in many different places. A few very specific dealers were therefore chosen. It is important to keep this point in mind for actors who also want to use a lot of reused materials. Site logistics is an important point of attention when working with reused elements.
A few points for improvement in the future:
Pay more attention to the finishing of the pipes that are to remain visible.
Concerning the implementation of the bricks we will try in the future to use a mortar bastard rather than a cement-based mortar. The same applies to the installation of tiles.

The project addresses the need for new sanitary facilities for the Chiro, which occupies the existing building. The building was designed in brick to best fit into the existing building environment, which is also constructed of brick. As mentioned earlier, two types of reused bricks were used: a yellow industrial brick and a rougher country kiln brick, including a classic version and a finer version. These bricks were laid in successive layers that repeat. The old red brick ensures the integration of the new building on the existing gable of the old farmhouse, while retaining its individuality through an atypical masonry pattern. The layered construction is an allusion to the masonry (sand-lime stone and brick in successive layers) of the Sint-Anna-Pede Chapel on the neighboring site.

Reasons for participating in the competition(s)
This project, through its humble program, is intended to be exemplary in terms of its materiality and the lessons it has generated. It was a question of testing through this project the implementation of a maximum of materials of reuse while keeping reasonable the budgetary and logistic considerations.
The construction was thus carried out with materials coming from 3 different channels:
- the reuse sector ;
- surplus from construction sites ;
- new construction.
Less than a third of the materials are new (in % kg).
In today's construction industry, reused materials and construction surplus are still very rarely used for new constructions and transformations; the materials are usually reduced to aggregates with little value. This modest construction project wants to show that things can be done differently and that the process to do so is not complicated.
