Wall House by Anupama Kundoo

Wall House in Auroville is an experimental house designed by sustainability champion Anupama Kundoo. The architecture employs a play in proportions to create comfortable yet dramatic spatial envelopes. The house is built entirely with locally sourced materials in new, innovative ways to create soothing, earthy spaces that respond to the warm, humid climate.

Wall House is predominantly constructed with the vernacular ‘Achukkal’ brick, once ubiquitous to the building landscape in Tamil Nadu. Known for their unique flat, thin profiles and their distinctive red colour, Achukkal bricks are typically made out of left-over silt that is collected from farmlands around. They are then shaped by hand and fired in clay ovens for strength and stability. The bricks are deemed to be extremely sustainable, given their long life, low cost of production, and the sparing amounts of energy use for manufacturing.

The earthy palette and warm finishes move beyond the brick walls and are found throughout the house. The august clay pot vault above the double-height living space and the innovative filler slab roof above the dining area are particularly worthy of mention.

Each facade of Wall House sports unique fenestrations that bring in fresh air and ample daylight. On one side, a series of louvered windows built out of local mango wood and completed with unpolished granite stone come into sight. On the other side, a series of pivoting ferrocement screens open the house to the verdant landscape around when open, and bring beautiful light and shadow patterns indoors when closed.

Sustainable Architecture - Building With Rammed Earth - Part I
 
 
 
 

In this IG Live, I speak to Donald Sequeira. Donald is an architect, natural builder, and the Director of Gia Mantra Global Village in Tiruvannamalai, Tamil Nadu, India. In this first part of our conversation on 'Building with Rammed Earth', we understand the fundamentals. We understand the potential and constraints of rammed earth as a material and learn about preparing the material for construction. We speak about the material's strength and stability and understand construction concerns such as building height and services. We also discuss the durability and maintenance of rammed earth over its lifetime.

Here are some common myths about rammed earth debunked:

  • A rammed earth structure can be built in all climatic regions.

    Rammed earth can be used for construction anywhere. It is a breathable but dense material that offers great heat exchange in tropical areas and thermal insulation in extremely hot or cold regions.

  • A rammed earth building is durable and has a lifespan greater than concrete.

    Rammed earth structures also possess strength that is at least equal to the strength of concrete. They are extremely sustainable in the long run and require minimum maintenance.

  • Rammed earth walls do not have to be very thick and there is no limit to room sizes.

    For a ground floor structure, only a 9" rammed earth wall is required which is equal to the thickness of a brick wall. As long as this criteria is met, it is possible to create spacious rooms of various sizes with rammed earth.

  • There is no threat of insects or pests entering the house through the rammed earth walls.

    Once compressed, the rammed earth wall becomes extremely hard and dense. While the material is breathable, it is not not porous. The density does not allow for passages to be made by pests.

The feeling of being inside a rammed earth structure is indescribable. The structure changes with the weather to protect you. It has a quiet, special, womb-like quality - one instantly feels cocooned.
