It is a hand-sized piece of molded clay, sun-dried or kiln-fired, joined with mortar to form walls, floors and vaults.

What it solves

It gives durable, fire-resistant walls with a small unit one person can lay alone. In seismic zones it needs tie columns and beams.

Today

Use locally produced brick and take advantage of its exposed face without plaster. Keep it away from damp ground and protect the top of the wall from rain.

Common mistake

Building brick walls without tie columns or beams in a seismic zone.

Tomorrow

Brick laid with lime mortar can be cleaned and reused. Unfired earth block saves the kiln’s energy and can be made with hand presses in the neighborhood itself.

Fact In the cities of the Indus, bricks followed a ratio of 1, 2 and 4 between thickness, width and length.

Masters

  • Eladio Dieste Church of Christ the Worker, Atlántida, Uruguay, 1960
    He created reinforced ceramics and with it built undulating walls and very thin brick vaults. He took a humble material to forms and spans that seemed impossible.
  • Marina Tabassum Bait ur Rouf Mosque, Dhaka, Bangladesh, 2012
    She used load-bearing brick walls with light courts open to the sky that ventilate and fill the prayer hall with light. It shows how much local brick can give on a very small budget.
