After his graduation in 2005, Vinu worked with Auroville Earth Institute for the UNDP (United Nations Development Programme) Post-Tsunami construction.

On returning from Pondicherry in 2007, he started ‘Wallmakers’ which was christened thus by others, as the first project was just a compound wall built utilising mud bricks and beer bottles, which was lying waste.

By 2008 he had received an award for a low cost, eco-friendly house from the ‘Save Periyar’ Pollution Control Committee for the house which was constructed for a cancer patient.

Thus far, Wallmakers have mostly constructed residential structures, while also working on different religious edifices, commercial buildings and even pavilions. The cottage predominantly uses compressed stabilised earth blocks (CSEB) which are essentially mud blocks. It is “construction material made using damp soil under a high amount of pressure to form blocks. CSEBs are composed of dry inorganic subsoil, non-expansive clay, aggregates and Portland cement, are an environmentally friendly alternative to clay bricks.

With climate change wreaking havoc on how we live our everyday lives and the emergence of an eco-friendly consciousness among many Indians, sustainable architecture has gone from a model once ignored to one which everyone wants to adopt.
