The method, popularised by world-renowned architect Laurie Baker, deploys kiln-fired bricks, supporting Trivandrum's dwindling brick kiln industry by employing local artisans.
Under the Rat Trap masonry construction method, the bricks are placed vertically rather than horizontally. This creates a cavity in the walls.
The cavity helps cut down the number of bricks and mortar used, further reducing carbon footprints and costs. It also provides insulation.
Vinu and his team further included an interesting twist by designing a series of slanting walls that look like they are dancing left and right. The design further elevates cross ventilation.
Vinu has also reused waste in the construction process. This includes discarded scaffolding pipes to form the central staircase and for the grillwork.
