At Studio L’ght, we firmly believe that the spaces we inhabit wield profound influence over our well-being and the environment. In much the same way we scrutinize the ingredients in our meals, we meticulously consider the components that constitute our architectural projects. We recognize that many mainstream construction materials and finishes harbor toxic chemicals, jeopardizing indoor air quality or bearing the weight of unethical production processes with colossal carbon footprints.
In this blog, we wish to introduce you to better alternatives – materials that not only enhance the health and comfort of your home but also honor our planet’s well-being. These natural materials, rooted in sustainability and natural composition, are a testament to our responsibility in choosing non-toxic, eco-friendly building materials for renovations and self-build projects. Not only are these choices mindful of the environment, but they also offer cost-effective solutions that draw from time-tested techniques.
So, join us on this enlightening journey as we uncover the alternative materials to creating a healthy home through mindful choices of internal wall plasters and finishes that will completely elevate your spaces.
Your space can be more than just walls; it can be a sanctuary of well-being, and we're here to show you how.
The Invisible presence of Volatile Organic Compounds (VOCs)
The impact of our choices extends beyond aesthetics; it touches our mental and physical health. Take, for instance, the phenomenon of ‘sick building syndrome,’ a condition linked to a gamut of discomforts, from skin irritations and congestion to headaches and difficulty concentrating. This ailment often arises from subpar ventilation, inadequate lighting, and the presence of airborne pollutants.
Volatile Organic Compounds (VOCs) are substances that can easily transform into gases, infiltrating the air we breathe. Some of these compounds have a distinct smell, while others remain stealthy and odorless. They can originate from construction materials or even biological sources like mold.
Among the troupe of VOCs, benzene and methylene chloride often take the stage in interior finishes, while formaldehyde silently lurks in engineered wood products like MDF or plywood. When we breathe in these particles or vapors, it can lead to a host of health issues, ranging from kidney damage to cancer. So, what can we do to create a healthier home environment?

Opt for a Sustainable Makeover
We always advocate for a more sustainable approach to home renovations and redecorations whenever we can. As sustainable construction methods gain traction, earthen and mineral plasters are experiencing a renaissance, delivering healthier and more resilient interior and exterior finishes compared to traditional plasterboard. This way, we not only prioritize your health but also contribute to a more sustainable planet.
Today, many people opt for a fresh coat of paint when rejuvenating their interiors or exteriors. However, most commercial paints come with downsides for both your health and the environment. The volatile organic compounds (VOCs) in these paints can adversely affect indoor air quality. In contrast, our approach favors zero-VOC paints such as limewash and clay paints, ensuring that your home exudes a sense of well-being.
Furthermore, the choices we make in terms of interior and exterior cladding materials significantly impact the number of natural resources required for home construction. For example, some homes clad in concrete blocks are further concealed by purely aesthetic exteriors like brick, rock, or vinyl siding. This reliance on additional materials notably increases the environmental footprint of the house.
As you embark on your journey to create a healthier home, consider using untreated timber, avoiding PU foams commonly used in window and door installations, and prioritizing the use of natural, sustainable materials wherever possible. Even taking small steps to reduce chemical usage can make a significant difference in fostering a healthier, more sustainable living space.
Think of it like choosing ingredients for a nourishing meal. Just as you wouldn't fill your plate with unhealthy, processed foods, you shouldn't fill your living space with toxic building materials.
The Ingredient Analogy
Imagine you’re preparing a wholesome meal for your family or friends. You carefully select fresh, organic ingredients, avoiding processed and chemically-laden foods. You know that the quality of these ingredients will not only influence the taste but also the health of those who enjoy your meal.
Similarly, when crafting your living environment, you should be just as discerning. Your home is more than just walls and floors; it’s the very air you breathe, the place where you rest, and the backdrop of your life. The materials you choose are the “ingredients” of your living space. Opting for sustainable, natural, and non-toxic materials is akin to choosing the best ingredients for your body’s nourishment.
A Ripple Effect
Every choice you make regarding your living space has a ripple effect. When you opt for toxic building materials, you’re not just affecting your immediate surroundings; you’re impacting the planet’s health and future generations too.
The interconnectedness of our choices is profound. Toxic materials release harmful substances into the air, compromising indoor air quality. This can lead to ‘sick building syndrome,’ where occupants experience a range of health issues. But it doesn’t stop there. These materials often involve unethical or unsustainable production methods, contributing to a large carbon footprint.
When you choose sustainable, non-toxic materials, you’re taking a step towards personal well-being and a healthier planet. It’s a responsibility we all share, much like our responsibility to care for our bodies by choosing nutritious foods.

1. Clay Plaster
Clay plaster is a natural and environmentally friendly alternative to traditional plaster finishes. It is made by mixing clay, sand, and fiber (such as straw) with water to create a workable paste. Clay plaster offers several advantages, including excellent vapor permeability, which allows moisture to pass through the walls and helps regulate indoor humidity levels.
One of the unique qualities of clay plaster is its ability to absorb and release moisture, which can contribute to a healthier indoor environment. It has a high hygric mass, meaning it can help balance indoor humidity and improve air quality. Additionally, clay plaster has anti-static properties, repelling dirt and dust.
In terms of aesthetics, clay plaster provides a warm and natural look to interior walls. It can be applied to various substrates, including brick, stone, and even drywall. Clay plaster is also versatile when it comes to finishes, as it can be left natural or painted with clay or lime-based paints.
While clay plaster offers many benefits, it is important to note its limitations. It is not as hard or impact-resistant as some other finishes, and it can erode if exposed to excessive moisture. However, repairs are relatively easy to make. Clay plaster is also a sustainable choice, as it has a low carbon footprint and can be sourced locally in many areas.
Overall, clay plaster is a healthy and environmentally friendly option for interior wall finishes, providing a natural and breathable surface that contributes to a comfortable and aesthetically pleasing living environment.
