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.

Utsav House by Studio Mumbai is a sanctuary of serenity. This elemental yet contemporary house in Alibag by architect Bijoy Jain sensitively makes room for intimate interactions with the surrounding greenery as it effortlessly bridges the indoor with the outdoor. The picturesque scenes and the connections to the tropical context resonate deeply with our values, the natural roots we turn to while designing and building houses in Goa. Built with locally available material and around numerous indigenous trees, Utsav House achieves poetic spaces that have a rustic simplicity without compromising on any of our modern creature comforts. Throughout, the focus is on intentional building and living, through architecture that takes cues respectfully from the terrain and landscapes around.

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.

Celebrating Navovado, our design-build vacation house in the Goan countryside through a gallery of photographs of the courtyard house. Earlier this year, Navovado won the prestigious Platinum Certification from the Indian Green Building Council. Navovado harvests all of its roof rainwater and recharges the water well on site. The use of low-flow water fixtures further improves water efficiency. Focus on use of insulation on the roof, double-glazed glass, low­energy use appliances, LED lighting and 100% hot water from Solar power makes this home extremely energy efficient. The structure is constructed using locally manufactured materials and materials with a high recycled content such as Laterite stone, Matti wood, Fly-ash brick and Slag cement. The garden is planted using native local species to reduce water use for ir­rigation. Finally, large openings allow for maximum daylighting and cross-ventilation, reducing the energy use for lighting and cooling.

The heart of the home lies in the large central courtyard that is an extension of the kitchen, living and dining space. The courtyard houses the swimming pool and provides a green private space to be enjoyed by all the residents of the house. The courtyard morphs in its use depending on the time of day and occasion. The guest bedrooms on the ground floor are designed as pavilions on either side of the courtyard, while the first-floor bedrooms have a large terrace overlooking the courtyard that connects the two levels.

In this IG Live, I speak to Malvika Mehta, Founder of MLIME. Malvika's team in Rajasthan has done some lovely work with lime plasters bringing the use of lime to modern buildings while also using it to conserve historic structures. Over our conversation we discuss the romance and practicalities of lime. We compare the use of IPS with lime and oxide, often found in old houses in Goa. We discuss the heritage of lime as well the potential it has to become a contemporary natural material. We get into details about lime's breathability, moisture management, and its effectiveness in indoor-outdoor spaces that are exposed to harsh heat and rain. We also speak about the process of making lime, its maintenance and cost efficiencies. Finally, we discuss the various finishes, colours and textures that a lime plaster comes in.

In this IG Live, we discuss the natural material wood and answer some important questions about our experiences while using wood in construction for our houses in Goa. Over the course of the Live session, I speak about crucial aspects that are often overlooked - such as sourcing and treating wood for the best performance. I have also presented the potential and limitations of reclaimed wood. Finally, I discuss whether wood can be considered a sustainable material.

I recently conducted a Q&A session on the use of stone as a building material to answer questions from students, architects, home owners and design enthusiasts. Over the live session, I have presented the different varieties of stone as well as the diverse finishes that are available. I have discussed the types of stone best suited for specific areas of a house based on factors such as utility, landscape and exposure to heat. I also speak about how different types of stone can be maintained, weighing the benefits of each type. Finally, I speak about the climatic impact and tolerance that stone has.
