Materiality in Modern Architecture

‘Materiality’ is an essential design informant in the world of modern architecture. It directly influences every aspect of architectural design , and is important in every architectural project. 

Since the start of the 20th Century, architects have selected materials for their inherent qualities and how these impact design. These qualities can be purely function — such as material strength, weight, and acoustic properties. Or can relate to the material’s natural aesthetic — such as its colour and texture. Today, architects place great emphasis on the story   of materials. The choice and juxtaposition of materials can tell you all you need to know about a building’s design. For example, locally sourced materials can tie a building to its surroundings and blend it seamlessly into its environment, and the contrast of concrete and timber can subconsciously make a space warmer (or colder). 

When a building’s materials are inherent in its design, rather than an afterthought, it makes all the difference to the result. The materials that every client should be acquainted with include concrete, timber, steel, glass, and masonry.

1. Concrete in Modern Architecture

Le Corbusier – Tower of Shadows, 1952

Concrete is the most prominent building material used around the world. It is a mixture of cement, sand, aggregate, and water which crystallises into the architectural wonder-material. It has an incredibly high compressive strength (making it ideal for any foundation), it is inexpensive, it is waterproof, and it is a highly desirable aesthetic in Architecture today. Its only significant downfall is its tensile strength, but this is easily rectified by the casting of steel ‘rebar’ into the material to form ‘reinforced concrete’.

In the design of a building, concrete can be used for everything from the aesthetic complexities of residential projects, to the great structural challenges of skyscraper design. Concrete can be made in a variety of colours and textures — making it a valuable material to consider when designing any building. It can be dark and polished for a more ornate aesthetic, or lighter with a board-formed texture to serve as a feature wall in a household. It is available in a variety of forms, grades and compositions. These affect the weight and strength of the result. Concrete is malleable and can solve just about any structural problem that may present itself during the design process.

2. Steel as More Than a Frame

Richard Rogers – NE0 Bankside, 2006 -2012

Steel has highly desirable structural properties. It has an unprecedented tensile strength and performs considerably well under compression as well. Concrete and steel together reinforce the structure of a building. This makes steel an optimal material for the construction of more significant buildings, and drastically improving the steel’s fire resistance in the process. Steel has exceptional aesthetic properties — its materiality is uniquely distinct, making it an ideal choice for any design that needs to represent simplicity, sophistication, and affluence.

Architects have been using steel for its aesthetic value since the modern movement. Today, steel adds more than structural integrity. Steel has since represented strength, elegance, and human innovation — leading Frank Gehry to design his most notable project, The Guggenheim Bilbao Museum, clad in reflective steel panels that spoke of the industrial era.

3. Glass Building Design 

Mies van der Rohe – Farnsworth House, 1945 – 1951

Glass is a unique material, as it has no structural value whatsoever, yet it serves as one the most important design devices in architecture. Apart from its elegant aesthetic, glass accomplishes more imperative functions in architecture — such as the drawing of light into a building, the creation of views to the outside world, the breaking of the enclosure, and the suggestion of space. Using glass can achieve a great variety of attractive aesthetics. However, glass best suits designs that require a lot of light considerably well. Glass panels can form series of walls that result in overall polished geometric forms. For residential projects, glass can be used to create views and admit light in a way that is aesthetically advantageous. It is ideal for contemporary-styled residential projects that require a clean, minimal appearance.

4. Masonry, Brick and Modern Architecture

Louis Khan – National Assembly Building, 1982

Masonry-construction is the most common method of construction in architecture. Bricks are extremely effective as a building material. Masonry buildings use modulating. This allows for ease of construction as it is inexpensive and can take the form of a variety of patterns. However, the term “masonry” does not only refer to brickwork. Instead, it encompasses several building methods that involve stacking form a wall or other architectural component. Another one of these methods is stonemasonry — which creates one of the most sought-after design aesthetics used in architecture today. The juxtaposition of masonry’s texture with the texture of another material allows architects to create narratives. These narratives can be about anything from the building’s construction, to the history of the architecture in the surrounding area. Masonry is one of the oldest methods of construction found in almost all vernacular architecture around the world – giving masonry-forward buildings a traditional and timeless feel .

5. And Finally, Timber

Robert Briccola –Weekend House in Vallemagia, 2009

Timber is one of the most aesthetically pleasing materials in Architecture. The lightweight material has been used in some of the most sophisticated architectural designs throughout history, most notably Japanese Architecture. This period prioritised the harmonious relationship between a building its natural environment.

Its strength-to-weight ratio makes it exceptionally versatile, along with its flexibility – which allows designs to accommodate for deflection and bending. Timber is traditionally a structural material for beams, columns and flooring. This is because of its lightness, insulation from heat, acoustic absorbance, oxidation resistance, and environmental compatibility. However, its aesthetic value gives timber its greatest quality. Timber-to-timber connections like the dovetail joint between a wooden beam and column, represent the simple beauty of modern architecture. These wooden components can also adopt a variety of colours and textures, depending on the final treatment of the timber.

Biophilic design is taking root in South Africa, changing how we think about our offices. It's a design approach that brings nature closer to people in buildings. Commercial architects using biophilic principles in workspaces know that nature has a massive impact on how we feel and work. Leading commercial architecture firms like Design Scape Architects are showing that this isn't just a fad. It's a smart, effective way to make offices healthier and more productive. These spaces, designed with nature in mind, are seeing a big jump in environmental value – a 200% increase in fact. Let's take a closer look. The Force Driving Biophilic Design Why the growing interest in biophilic design? Because our connection to nature is hardwired. In South African offices, biophilic design means: 1. Less stress, better mood: Natural light, views of plants and water features create a calming atmosphere. Simply adding plants to an office can cut stress and absenteeism by a hefty 50%! 2. Sharper focus, higher productivity: Nature helps us concentrate better and sparks creativity. With biophilic design, employees find it easier to focus, leading to better work. Providing employees with access to natural views could potentially save your business over R30,000 per employee per year in office costs. 3. A sustainability boost: Biophilic design often walks hand-in-hand with eco-friendly practices. Think of natural ventilation, water-wise landscaping with indigenous plants, and using locally sourced, natural materials. Biophilic Principles in Action Here’s how commercial architects use biophilic design to transform your workspace: Light and space: Skylights and expansive, high-performance glazing flood interiors with natural light. Open layouts and atriums create a sense of spaciousness, minimising the need for artificial lighting. Environmental features: Carefully chosen plants are integrated into the design, including those used on green walls and vertical gardens. Indoor water features add a calming element. These features purify the air and create a sense of tranquility. Natural materials: Priority is given to locally sourced, sustainable timber and natural stone. These materials create a tactile connection to the earth and improve acoustics. Natural patterns and processes: Subtle integration of natural patterns – a Fibonacci- inspired staircase detail and fractal-patterned screens – creates a sense of harmony. The design also accounts for the dynamic interplay of light and shadow throughout the day. Place-based relationships: Buildings are designed to fit their South African context. Indigenous landscaping and regionally-inspired design elements Let's Bring Biophilic Design to Your Office Design Scape Architects puts biophilic design into action. For example, we turned a barren concrete courtyard at FNB Bank City into a green oasis, complete with indigenous plants and natural materials, giving employees a natural escape in the city. Our Ecology Park project in False Bay exhibits how buildings can blend seamlessly with nature, using sustainable methods and highlighting the surrounding environment.

South Africa has a rich and diverse architectural heritage that spans centuries, showcasing influences from indigenous cultures, colonial powers, and contemporary design. The country's architecture reflects its complex history, cultural diversity, and evolving identity. From ancient structures to modern landmarks, South Africa’s architectural heritage offers a fascinating journey through time via its built environment. Here's an overview of the key architectural styles and important sites: 1. Indigenous Architecture Indigenous architecture in South Africa dates back thousands of years and is defined by the materials and techniques available in the environment. Various communities have distinct architectural traditions: ● Zulu: Traditional Zulu homes are amakhaya (circular huts) made of thatch, with walls constructed from mud, clay, and reeds. ● Khoi-San: The Khoi-San people lived in temporary shelters, often consisting of woven reed huts that were designed to be mobile. ● Xhosa: Traditional Xhosa homes are round, with thatched roofs and walls made from mud or clay. These structures were designed for functionality, reflecting a close relationship with nature and the surrounding landscape. 2. Colonial Architecture South Africa's colonial history, shaped by the Dutch, British, and French, left a deep imprint on its architectural landscape. Key styles include: ● Cape Dutch Architecture: Emerging during the 17th and 18th centuries, this iconic style features whitewashed walls, curved gables, thatched roofs, and timber windows. Notable examples include the Iziko South African Museum in Cape Town and Vergelegen Wine Estate in Stellenbosch. ● Georgian Architecture: Introduced during the British colonial period in the early 19th century, Georgian architecture is characterised by symmetry, brick facades, and sash windows. An example is the Old Government Building in Cape Town. ● Victorian Architecture: Victorian structures, popular in the late 19th century, often included ornate detailing, high ceilings, and decorative elements such as wrought-iron verandas. St. George's Cathedral in Cape Town is a fine example. 3. 20th Century Modernism and International Styles The 20th century brought modernist influences to South African architecture, especially during the interwar period. These designs embraced new materials and technologies, such as concrete and steel: ● Art Deco: This style is visible in some early 20th-century buildings, characterised by bold geometric patterns, sleek lines, and decorative motifs. ● Modernism: Post-World War II, modernist architecture prioritised simplicity and functionality. Concrete was used extensively, and building forms became more abstract. An example is the University of Cape Town’s architecture, with designs by architects like Sir Herbert Baker. ● Brutalism: This mid-20th-century style focused on raw concrete and geometric forms. A notable example is the Breezeblock Building in Johannesburg. 4. Apartheid and Post-Apartheid Architecture During the apartheid era, architecture played a significant role in social engineering, especially with the forced removals and segregated spaces for black and white populations. Post-apartheid architecture focuses on healing, inclusivity, and social justice. ● Apartheid Architecture: The urban design and architecture of the apartheid period included racially segregated cities, townships, and the construction of sprawling housing complexes for non-white populations. District Six in Cape Town is an example of an area where residents were forcibly removed under apartheid policies. ● Post-Apartheid Architecture: After 1994, architecture began promoting healing and inclusivity. Projects like Constitution Hill in Johannesburg, a former prison turned into a museum, reflect this shift toward national unity. 5. Notable Heritage Sites and Buildings South Africa is home to numerous buildings and sites of architectural significance, many of which are recognized as national heritage sites. Some of the most important include: ● Robben Island: A symbol of South Africa’s struggle against apartheid, Robben Island, where Nelson Mandela was imprisoned, is an essential landmark of both history and architecture. ● The Union Buildings (Pretoria): Designed by Sir Herbert Baker, the Union Buildings house the offices of the President of South Africa and are a cornerstone of the country's political and architectural heritage. ● Castle of Good Hope (Cape Town): Built by the Dutch in the 17th century, the Castle is the oldest surviving colonial building in South Africa and serves as a military museum. ● Stellenbosch Village: Known for its well-preserved Dutch colonial buildings, Stellenbosch is often regarded as the best-preserved village in South Africa in terms of architectural heritage. ● The Apartheid Museum (Johannesburg): This museum is housed in a striking contemporary building designed to represent the harsh and brutal reality of apartheid, using concrete and steel to evoke the time period's emotional weight. ● Soweto: Home to some of the most significant events in South Africa's history, Soweto is an area where traditional African housing is juxtaposed with modernist and late 20th-century designs. 6. Conservation Efforts South Africa has made significant efforts to conserve its architectural heritage. The National Heritage Resources Act (No. 25 of 1999) was established to protect the country’s built heritage, including both historical buildings and cultural landscapes. Many historic sites and buildings are protected as national heritage sites, and a number of organizations work to maintain and restore these structures. ● Heritage Protection: The South African Heritage Resources Agency (SAHRA) is the government body tasked with safeguarding the country's cultural and architectural heritage. ● Adaptive Reuse: Many old buildings have been repurposed for new uses while maintaining their historical integrity. For instance, the V&A Waterfront in Cape Town has transformed from a working harbour to a vibrant retail and tourist destination while preserving many of its historic buildings. 7. Key Architects and Influences ● Sir Herbert Baker: An English architect, Baker had a significant influence on South African architecture, particularly in designing government buildings, including the Union Buildings. ● Norman Eaton: A South African architect known for his modernist designs and contributions to post-apartheid architectural thinking. ● Hans Hallen: Known for his work on the apartheid-era buildings that reflect the policies and social dynamics of that time. Conclusion South Africa's architectural heritage is a powerful narrative of the country's history, from the indigenous people who built with local materials to the European settlers who left their mark through colonial designs. Today, the blend of old and new, alongside efforts to conserve and reinterpret the past, shapes South Africa's contemporary identity. Whether through the grandeur of colonial architecture or the profound symbols of resistance, South Africa’s buildings continue to tell the story of a nation evolving and embracing its multifaceted heritage.
