A Guide To Sustainable Interior Design In 2024

What is Sustainable Interior Design?

Sustainability in interior design means achieving a balance between old and new materials. Recycling, upcycling and reusing are key directives. They help reduce the amount of waste produced by renovation and building projects. Sustainability also ensures that the use of new materials is kept to a minimum. Interior designers are helping us realise how sustainability works.

Sustainability gives a new lease of life to unwanted components and spares sending materials such as old tiles and kitchen cupboards to landfill sites. Instead, they are reused and upcycled.

Tips for sustainable interior design

1. Design for energy efficiency.

Energy consumption is one of the major contributors to climate change, so improving a building’s energy efficiency is key. To do that, we can design with the intention of reducing the amount of heating and lighting required, and by providing renewable energy to the building. For example, since most heat comes in and escapes through windows, it’s important that windows and window coverings provide good insulation.

2. Design for low environmental impact.

It’s important to choose materials and products with a low environmental impact. Organic materials, such as wood, wool and stone, are a good choice – as long as they are responsibly sourced. Consider the environmental impact of throughout their entire life cycle, from extraction, production, transportation and processing, all the way through to how they are discarded after use.

3. Design for waste reduction.

To reduce the amount of waste, designers can look towards recycling, upcycling and repurposing in their designs. Using synthetic materials that have been made from recycled waste, or that can be recycled again at the end of their lives, is an easy way to engage in the circular loop of design.

4. Design for longevity and flexibility.

The goal of designing for longevity is to create durable and timeless spaces that will stand the test of time. The best way to achieve this is to choose quality over quantity and classics over trends. The flipside of longevity is flexibility. As people’s tastes and lifestyles change, they want their spaces to grow with them and reflect those changes. In anticipation of that, you should design flexible spaces that change and adapt to new needs, removing the need to demolish and start from scratch.

5. Design for healthy environments.

It’s important to protect the health of the people who will be living in or using your building, by considering things like the quality of the air, heating, ventilation, lighting and acoustics.

Here are two business examples where sustainability is at the core of their business: nina+co and Breathe.

What are examples of sustainable materials for interior design?

Sustainable interior design has a neutral or positive effect in the environment. Good materials include bamboo, rattan, terrazzo, polished plaster, reclaimed wood, glass, and natural stone. They are all environmentally friendly and have a low carbon footprint.

Bamboo

Bamboo is considered a sustainable material, as it is fast-growing (it is actually a grass, not a tree), quickly renewable and it takes less energy to produce than wood. This makes it an A+ material in terms of energy efficiency, production process and use of natural resources.

Incredibly versatile and beautiful, bamboo is a very strong material which can be used structurally and is also very flexible. Bamboo can be used in many ways such as in window treatments, flooring, walling and in decorative ways. When we think Bamboo we think relaxing spaces in Ibiza, Mykonos and Asia. To no surprise Soho House has created this natural material into something very chic and trendy in their new Mykonos Soho Roc House. Also, depending on the design, bamboo can be statement piece for residential spaces.

Rattan

Perhaps one of the trendiest materials at the moment also happens to be environmentally friendly. Rattan is quite similar to bamboo in terms of its sustainable benefits. It is fast growing, is produced in a low energy and low waste way (meaning it doesn’t have to be treated and processed that much),and since it is a natural material, it is recyclable and biodegradable. This versatile material can be produced in unique patterns, giving a rustic feel to any residential living room or home office. Because rattan is light and relatively flexible it is most commonly used in furniture, chair covers, wall cladding, joinery and screening.

Terrazzo

If you like stone you might also consider Terrazzo; a great way to give a new life to stone and produce significantly less waste. Terrazzo has been used in Italy since the 18th century to create enticing, textured floors. By utilizing mixed marble scraps, recycled glass chips and cement – terrazzo is crafted from the waste materials of other projects. These small particles are combined to create the unique terrazzo designs we see – leaving virtually nothing to waste. As environmentally-friendly architecture becomes more and more imperative, terrazzo’s durability and long-lastingness continue to be a huge advantage in today’s world. Today it can be found on tables, walls, floors and bathroom sinks, amongst other interior items.

Polished Plaster

Interior rendering is growing in popularity. Achieving a concrete look that doesn’t have the environmental impacts a concrete wall does is truly amazing. The 4 finishes to look out for include Lime Wash, Tadelakt, Micro Cement and Clay Plaster. These amazing finishes can really enhance a space, bringing a softness and warmth unlike any other material. They are particularly impactful in a bathroom replacing the cold feel of tiles. These finishes are naturally made and non-allergenic. They contain no toxins or gases (no VOC’s) so are a great option to replace paint.

Reclaimed wood

An obvious one and definitely one of the most popular options available. Reclaimed wood creates a sense of warmth and familiarity in a space. By using reclaimed wood, you not only reduce your footprint, you are also adding sustainability to your home. A lot of these repurposed pieces of wood have a real history to them such as railway sleepers and old warehouses. Rich in history and texture, reclaimed wood is one of our favourites.

Glass

Beautifully crafted, undeniably fragile and effortlessly delicate, glass also happens to be endlessly recyclable. For centuries glass has been used in interiors to create decorative form and texture as seen in places of worship.Through recent years, glass has seen great development with endless types being used in interiors including frosted, etched, tinted, laminated and our personal favourite reeded. When trying to open up a space, glass is always a great option and is perfect for cabinets, walls, splash backs and furniture.

The Importance of Sustainability in Interior Design

Sustainability is not just a buzzword; it is crucial for the future of our planet. Interior design has a significant impact on the environment, from the extraction of raw materials to the energy consumption during manufacturing and the eventual disposal of products. By adopting sustainable materials, interior designers can minimize their ecological footprint and promote a healthier living environment for both present and future generations.

Additionally, sustainable design can contribute to enhancing the well-being of occupants. Studies have shown that incorporating sustainable elements in interior spaces, such as using natural light and non-toxic materials, can improve air quality, reduce stress levels, and increase productivity. Natural light, for example, not only reduces the need for artificial lighting but also provides a connection to the outdoors, creating a sense of harmony and well-being.

Use of Sustainable Materials 

Designers are taking into account life-cycle and the long-term environmental impact of the materials.  The impact is well thought throughout all phases of production and later disposal of used sustainable construction materials.

• Hempcrete or Hemplime - combines hemp shiv, lime and water to create a concrete-like material that is strong, durable, flexible, breathable, mould-proof and fire resistant. Hempcrete homes are carbon-negative, they take more CO2 out of the atmosphere than put in during both construction and the lifetime of the building.

• Cork - the cork tree is not cut down to obtain cork, only the bark is stripped to harvest the cork and the tree continues to grow.

• Straw bales - take little energy to manufacture and it is a renewable material. Straw is used often as bedding.

• Organic Cotton - it is grown without the use of pesticides, herbicides or other chemical fertilisers. It has a huge benefit to your health as well as the environment.

• Felt - is a textile material that is produced by matting, condensing and pressing fibres together. It is a low-impact and completely biodegradable material. It has its use in  making drapes and furniture.

• Jute - it grows quickly, between 4-6 months. It is an efficient source of renewable material similarly to bamboo - jute absorbs carbon dioxide and releases oxygen much faster than trees (used often for rugs).

Furthermore, sustainable materials often have a lower carbon footprint compared to their conventional counterparts. For instance, using reclaimed wood instead of newly harvested timber reduces deforestation and carbon emissions associated with logging and transportation. By choosing sustainable materials, interior designers can contribute to mitigating climate change and preserving natural resources.

In conclusion, sustainable materials in interior design offer numerous benefits, from reducing environmental impact to promoting well-being. By incorporating these materials into their projects, interior designers can create spaces that are not only aesthetically pleasing but also contribute to a more sustainable and harmonious future.
