The House with Three Pavilions is a sustainable house in Goa, designed and developed by GROUNDED.

The house explores the intimate relationship between the land, its people, water, and the biodiversity that exists in Goa in India. It is designed as a cluster of three pavilions that gently weave around existing trees in an attempt to coexist with nature and to minimize the impact of new construction on virgin land.  

The architecture of the house takes inspiration from the surrounding Goan village houses. Mostly constructed as ground-floor structures, each pavilion attempts to match the volumetrics of its village peers. Throughout, a simple sweeping roof form is used in red terracotta tile that is ubiquitous to the Goan village built-landscape. Proportions are borrowed from doors, windows, and plaster bands of vernacular Goan structures even as a distinct contemporary style is articulated in the design.

With a focus on connection with nature, the materials used in the house are kept subtle and natural. All floors are finished with a natural Indian ‘kota’ stone in a blue-green color that merges with the landscape. Pigmented cement and exposed local ‘laterite’ are used extensively to mirror the rustic countryside character. ‘Teak’ is used for doors and windows to add warmth and rich texture to the interiors. Antique wood columns and stone pedestals are also incorporated to bring a sense of luxury and timelessness throughout.  

The project also prioritises the enhancement of the site’s resources and biodiversity through a comprehensive water-management system which includes a natural seasonal pond connected to a newly planned system of bioswales. This on-site wetland feature harvests rainwater, recharges depleted underground aquifers, and offsets the load on the public drain system. Furthermore, it preserves the pre-existing site habitat. It is a win to see that insects, birds, and animals continue to find the site a safe space even as they come in close contact with the human life around, making this truly a space for all seasons and species.

I recently conducted an IG Live on taking A Site Positive Approach. As a follow up to that, I conducted another video session to get into details and answer pertinent questions about Rainwater Harvesting. I discuss the elements that make up a RWH system, compare the differences between rural and urban water management systems, and introduce some of the various options available for harvesting water. I also speak about the Goan monsoon patterns and the site specific methods that are useful in tropical areas. As an example, I explain the simple but effective well system created at Navovado, our completed vacation house in Goa. I also explore natural water systems such as ponds and bioswales which we have physically implemented at our project The House with Three Pavilions in Goa.

In this IG Live, I delve into the factors involved in taking A Site Positive Approach. I speak about how design can contribute to the land it stands on as well as simple measures that can be taken to ensure the site is preserved and that resources are managed well during and after construction. Over the Live, I explain the importance of the water management systems at our houses in Goa, and the natural systems we have implemented such as a pond and bioswales. I also answer questions about site positivity in the rural and urban contexts, speak about the opportunities offered by certain materials and the feasibility of creating a positive impact. Tune in to watch the entire session.

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.

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.

I was invited by Architecture + Design magazine to discuss Green Architecture, its nuances, realities and myths.

It is pertinent now more than ever to create buildings with minimal architectural intrusion and the conservation of natural resources. In this session, I speak about conscious architecture based in context and the little steps that we can take in our pursuit for ecological balance and sustainability.

To the jaded, the mention of green buildings implies a marketing gimmick, and to an idealist, it conjures images of buildings built with mud and bamboo with compostable toilets. Invoking a strong response either ways, we recently concluded a Q&A session on Green Buildings on Instagram. The session had over 300-people join over the course of a 30-minute session. 

The first question that we tackled was, ‘What is a Green Building’? My answer, ‘A green building is one where you’re trying to reduce the impact of the building on the environment.’ It is about making the right choices at every stage of the project, with the ultimate goal to minimise one’s footprint on the environment. To make a building green, the architect must treat the environment as a key design criteria from the first step of the design process right until the occupancy stage. 

It is our commitment to build sustainably and we green certify all our houses in Goa. Our first home, Nivim was the first green certified residence in Goa. It received a gold-level certification and our project Navovado has recently been awarded the platinum-level certification by the Indian Green Building Council. Platinum being the highest level available in the ranking system.

While a building can absolutely be green without a certificate, a green certification is a great way to stay accountable to oneself throughout the design and construction process. It provides the involved professionals with a detailed list of checks and balances with specifications and design criteria that need to be considered and incorporated at every stage of the design and construction process.

In India, TERI (home-grown) and IGBC (offshoot of USGBC) are the primary agencies that issue green certifications. Both these organisations use a credit based system for the evaluation of green building design and performance. The credits fall under the following categories: Site Planning, Water Efficiency, Energy Efficiency, Indoor Air Quality, and Materials among others. Throughout the process, extensive documentation with detailed calculations are required which is then reviewed and tested by the certification body on site. While the system is elaborate, it proves effective as a way to stay true to one’s goals of sustainability. However, it is important for architects to avoid incorporating design elements or features, just for the sake of securing points and focus instead on strategies that are feasible for that specific project life cycle and use.

Demystifying Green Building

I would like to cut through the clutter on this topic. Specially as I would like to demystify the concept and express that green building design is not necessarily a specialized science, nor is it forbiddingly technical where only certain qualified professionals can build green buildings. On the contrary, it is my strong belief that a building built with the basic principles of good architecture would do very well on the green scorecard. The process of green building design starts with a deep understanding of the site, local climate, wind patterns, local materials and resources. Once a building is sited to take advantage of the sun and wind to maximize daylight and cross ventilation, is designed to be responsive to the weather patterns and is built using local materials, then that in itself is a great start towards making the building green.

In the predominantly hot and humid climate in India, one can further think of reducing the heat gain through an informed design of the building envelope. This will have a tremendous impact on the thermal comfort within a building and hence reduce the energy use in the building. Water is another key natural resource that is dwindling with increased human activity on our planet. Rainwater harvesting provides a simple (sometimes ‘no-brainer’) solution to this problem. The idea is simple, instead of allowing rainwater to drain away from your site, one can design systems to either collect it and reuse on the site itself, or feed it back to the earth to recharge the underground aquifers. In addition, a simple introduction of dual flushes can reduce water use by 50-60% and aerators to taps, which can reduce the water use by upto 70% percent. Aerators mix the water from the taps with air, and as a result the water pressure feels the same even when the amount of water flowing through the taps are reduced.

When it comes to building materials, it is wise to use local materials. In most cases, the vernacular building techniques and the local labor would be well versed with the local material. The green quotient of buildings can be further increased by choosing materials with a higher recycled content, higher recyclability, reusing salvaged materials and materials that are rapidly renewable such as bamboo.

The choices to go green are not always straightforward. Cement for example presents a big conundrum in the building industry. The production of cement produces large quantities of CO2, a greenhouse gas with a lasting impact on global warming and climate change. In fact, the production of every kilogram of Portland cement produces an equal amount (one kilogram) of CO2. This presents a huge challenge for our industry where the widely accepted structural material is cement. Wood is another material that presents a difficult choice with sustainability. On one hand, it is a naturally renewable resource and is biodegradable, and wood can be used and reused multiple times. But at the same time, we are cutting irreplaceable virgin rainforests at an alarming pace with long lasting disastrous impact.

Finally, a green building doesn’t have to cost a lot more. Majority of green building strategies are common sense and based on sound architectural principles, which do not come with an additional cost. In addition, there are simple systems that are available at extremely reasonable prices. The aerators mentioned earlier are a free addition offered by most companies that sell sanitary fittings. The difference is for the architect, client and the vendor to be aware of these systems and integrate them into the building design in a timely manner. 

We must as a community of architects pledge to make green building design as important as aesthetics in our projects. A simple change in the thought process can have a long lasting impact on the quality of life for our future generations, which is a cause worth fighting for.
