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
New Wall Design
- The new wall design incorporates thermal mass and insulation through innovative layering techniques using local earth and recycled materials.
- Three types of walls were developed: dense stone-filled walls, contextual facing walls, and insulated walls without stones based on specific needs.
Structural Considerations
Layering and Material Use
- A stratification system was implemented in the wall design transitioning from concrete foundations to lime finishes at the top for reduced resistance.
- This approach enhances thermal stability while maintaining aesthetic connections with surrounding architecture.
Redefining Project Briefing
Sustainability Focus
- The competition brief emphasized sustainability through decarbonization using timber; however, Tudor proposed reusing mineral materials as an alternative strategy.
- Their final design featured self-standing stabilized walls that utilized existing site materials effectively while ensuring structural integrity through compression rather than bending elements like timber slabs.
Construction Process Reimagined
Shifting Traditional Methods
- Tudor advocates for shifting traditional construction processes by prioritizing material reuse before demolition to inform new designs better.
- This method allows simultaneous research into material properties while designing structures tailored around them.
Efficient Material Management
Block Creation Strategy
- A strategy emerged involving creating larger blocks from salvaged materials that could be easily stored and transported.
- This approach streamlined construction efforts by allowing prefabrication of components before assembly on-site.
Foundation Innovations
Basement Construction
- Due to poor geotechnical conditions, deep foundations were necessary; thus, they incorporated recycled concrete into basement construction.
- Above ground levels utilized prefabricated blocks combining lime and cement for enhanced stability.
Defining Space Through Structure
Architectural Philosophy
- Emphasizes how structure can define space rather than relying solely on non-load-bearing elements.
- Explores how different projects have successfully integrated this philosophy into their designs over time.
Thermal Comfort Strategies
Utilizing Thermal Mass
- Discusses how compressive mineral walls provide excellent thermal comfort by storing energy efficiently in Mediterranean climates.
- Highlights strategies such as nighttime ventilation that leverage thermal mass benefits during hot days.
Verticality in Design
Gravitational Organization
- Advocates for vertical organization of matter as more natural compared to horizontal layouts often seen in modern architecture.
