Vivienda Unifamiliar y Colectiva

Main Ideas, Concepts, and Lessons

• Housing evolves historically, not by chance

  • Today’s ways of living are framed as the result of a long historical “distillation” of building processes:
    • cave → cabin → house → grouped houses → cities.

• Single-family homes require a strong fit between form and program

  • Single-family houses are often described as isolated, and therefore expected to respond to their own spatial/program needs.
  • Municipal regulations increasingly constrain design, including details such as color and visibility (e.g., being prohibited from painting a house white because it was considered too conspicuous).

• Terrain strongly shapes the architecture of single-family homes

  • Land characteristics determine how a house integrates with its site (e.g., “shape coefficient” / fit).
  • Two contrasting strategies are highlighted:
    • Hide/disguise parts of the house by burying volume and using terraces.
    • Expose and reference the house as a more autonomous landmark when the goal is not to dominate or disrupt the landscape visually.

• Architectural education and communication with clients matter

  • For single-family work, the speaker emphasizes “customer education” so architect and client “speak the same language.”

• Designing single-family homes is also about shaping dreams

  • The house is portrayed as a personal, emotional “big decision,” similar to a life milestone (e.g., after partnering/marriage).
  • The architect must therefore understand that it is effectively the client’s dream.

• Consistency over time in an architect’s production

  • The speaker claims a ~30-year continuity in approach:
    • Most projects share a coherent architectural sensibility.
    • Only one or two would be done differently today.
    • Projects are described as “sisters” (from the same “hand”), evolving as the world evolves.

• Geometric / space-expanding strategies

  • Diagonal geometry is presented as a key lesson for increasing perceived spatial dimension:
    • Same rectangle area, but splitting it increases diagonal length, which increases the sense of spaciousness.
  • Examples include:
    • A Comarrugas house described as almost a Möbius strip, where floors become walls and walls become ceilings in a continuous loop.
    • Triangular plots used to create “lookout/periscope” views toward the sea (Pineda).
    • Arange houses (15 different homes) intentionally avoid repetition to prevent boredom for both clients and builder.

• Collective housing defines cities

  • The talk contrasts:
    • Isolated single-family homes (beach, mountains, rivers).
    • Cities built around collective living as a shared project.
  • The speaker emphasizes experience constructing multi-family/collective housing in multiple locations.

• Project opportunities are hard to predict

  • The “source of orders” is described as uncontrollable—compared to weather—so opportunities arrive unpredictably.

Methodology / Instruction-Like Points (as Presented)

1) Approach to Single-Family Design

• Acknowledge constraints

  • Expect municipal regulations to affect color, visibility, massing, and related decisions.

• Choose how the house relates to the site

  • If you want discretion:
    • bury parts of the volume,
    • use terraces to step/mediate the terrain,
    • mask/disguise the structure.
  • If you want prominence:
    • allow the house to be seen,
    • treat it as an autonomous landmark/reference point.

• Use terrain to determine form

  • Let site conditions drive integration decisions (shape coefficient/massing).

• Plan for practical underground/hidden functions

  • Excavated areas are described as useful beyond garages (e.g., storage, cellars, hobby rooms).

• Educate the client

  • Build shared understanding so priorities and design logic align.

• Treat the project as dream-shaping

  • Recognize the emotional/personal weight of the house as the client’s life milestone.

• Maintain internal design continuity

  • Ensure new projects stay consistent with the architect’s evolving authorship.

2) Spatial / Geometry Tools Highlighted

• Exploit diagonals to enlarge perceived space

  • Use geometry where increasing diagonal length enhances spatial sensation.

• Employ transformational forms

  • Create continuous or metamorphic relationships between floors, walls, and ceilings for spatial fluidity.

• Use plot geometry for framing views

  • Triangular plots can concentrate viewpoints (e.g., toward a wide sea view).

• Avoid model repetition in repeated housing

  • When delivering many units, vary models so clients aren’t repeatedly paying for the same house concept and the architect isn’t trapped by boredom.

---

3) Approach to Collective (Multi-Family) Housing

• Make common spaces truly common

  • Design shared circulation and amenities so residents actively experience shared life.

• Integrate practical shared functions without visual clutter

  • Example: laundry drying in patio areas not visually exposed from key viewpoints, while still near stairs/elevators for convenience.

• Use transparent or panoramic systems to strengthen “sharedness”

  • Example: a panoramic elevator through a glass courtyard to make the common core feel communal.

• Adaptive reuse with careful counting / surface-area constraints

  • Example: converting an old bank into student housing:
    • create glass walkways that don’t count as built surface area,
    • access apartments from behind,
    • expose/install routes for infrastructure surveys and registration.

• If surroundings are poor, “turn inward”

  • Redesign collective housing to close off unattractive exteriors and focus on:
    • inner courtyards,
    • internal variety (e.g., different colors by floor/courtyard to counter external monotony).

Main Examples / Projects Mentioned (by Location)

Single-Family

• Tamarío (municipal constraint example: prohibition on painting the house white)
• San Feliu de Codines (1989): “subtracted” house concept; top built on a wall to look back to the city
• Valdorecha: studying diagonal geometry
• Comarrugas: geometrical, Möbius-like transformation house
• Pineda: triangular plot creating near-periscope focus toward the sea
• Arange houses: 15 different homes, avoiding repetition of models (partners mentioned)

Collective / Multi-Family

• Tulu, France: early social housing project; won an award (1993) referenced by the speaker
• Barcelona (multiple operations):
  • Homero Street
  • San Ramón Non
  • Osi area
• Tarras: renovation of an old bank into housing using a transparent walkway strategy; student installations and courtyard wall approach using a product/system (“prodema” mentioned)
• Zabadella (Ensanche district): reworking a completed project; black-box exterior; internal courtyards and internal color differentiation to improve living experience
