HARQUITECTES - Organizing matter: Social housing in Palma de Mallorca

Introduction to the Lecture Series

Welcome and Overview

  • The lecture series resumes with a special guest, Roger Tudor, founder of H Architectus.
  • Tudor discusses the art of construction aimed at creating good spaces, starting from a project initiated four years ago.

The Competition for Social Housing

Initial Challenges

  • The competition involved an existing building (an old school) that was in poor condition internally but structurally sound externally.
  • There was a contradiction between the need to demolish the building for new construction versus its potential for reuse.

Discovery of Building Materials

Material Insights

  • The building was primarily constructed with local sandstone from Mallorca, which is common in older constructions.
  • Initially expected materials included bricks or other structural systems; however, it turned out to be vertical walls made of stone and concrete slabs.

Previous Project Experience

Learning from Past Projects

  • Tudor reflects on a previous project where they faced similar demolition challenges due to urban regulations affecting an existing wall surrounding a plot.
  • They aimed to create a contemporary structure while reusing original stones from the demolished wall, connecting modern design with historical context.

Innovative Construction Techniques

  • Notes the aesthetic appeal of the structure, likening it to Moroccan architecture while integrating traditional systems with contemporary design.

Traditional Techniques in Modern Construction

Use of Marz System

  • Describes the decision to utilize a traditional building system involving smaller blocks (Marz), which enhances structural balance through wooden pieces.
  • Explains how filling surfaces with liquid mortar creates a solid mass within walls, contributing to overall stability.

Aesthetic Qualities of Materials

  • Mentions the unique textures produced by varying cement and lime quantities across different levels, enhancing visual appeal.

Balancing Lightness and Stability

Structural Design Choices

  • Details how lighter materials like timber and glass were used strategically where walls were absent, creating an airy feel.
  • Discusses thinner walls that contribute both to stability and spatial definition within the building layout.

Functional Layout Considerations

Common Spaces and Room Distribution

  • Outlines how all units face a central patio, promoting community interaction while maintaining privacy through strategic room placement.

The Power of Structure

Visual Impact During Construction

  • Reflecting on a moment when only structural elements were visible, creating a powerful impression before finishing touches were added.

Historical Context in Architectural Design

Addressing Practicality vs. Aesthetics

  • Discusses balancing historical architectural styles with modern needs; acknowledges imperfections as part of practical solutions.

School lecture series at EPFL Architecture Tuesday, March 18, 2025 EPFL, Auditorium SG This lecture is part of the lecture series "Housing and Reuse: Six Exemplary Projects" The main strategy of the project is to reuse the materials of the old school demolition to construct the new building, with an ‘urban mining’ approach where the resources come mainly from the existing urban plot. The spatial organization and climatic behavior answers to the structural system as a new organization of the existing matter. Roger Tudó is a principal and founding partner of the architectural firm H ARQUITECTES based in Sabadell (BARCELONA) and founded in 2000 together with David Lorente, Josep Ricart and Xavier Ros. He had been combining his professional activity teaching in the ETSAV-UPC, Harvard GSD and ETH Zurich. Their work has been published in several magazines such as El Croquis, 2G, AV, A+U, Domus, Detail, Casabella, etc. and exhibited at Venice Biennial 2016 in the Spanish Pavilion, awarded with the golden Lion, at Lisbon Architecture Triennale 2019 and at Utzon Center in Aalborg 2021, etc. 00:00:00 Introduction by Pier Vittorio Aureli 00:00:22 Lecture by Roger Tudó 00:50:42 Q&A _ Housing Vol.2. "Housing and Reuse: Six Exemplary Projects" For the Spring 2025 Lecture Series, the School of Architecture at EPFL has invited six architecture offices to discuss housing and reuse through six exemplary projects. The lecture series will be complemented by the launch of Professor Charlotte Malterre-Barthes’s “A Moratorium on New Construction”. Reuse of existing buildings is increasingly becoming a good practice. Yet, reuse is easier said than done. Within a capitalist society, buildings are produced as commodities and, as such, they are not meant to last. Moreover, what is at stake within reuse is not simply the reuse of buildings per se, but the whole process of building production behind each architectural project. This lecture series explores projects of reuse in which former offices, factories, or houses are transformed or expanded as residential spaces. Each lecture focuses on one building in order to shed light not only on the advantages of reuse but also on its limits and challenges.
