Alero Olympio (1959-2005) was an architect and builder known for an intimately ecological approach to architecture. Born in Ghana, she divided her practice between Ghana and Scotland. She focused on work that prioritized people and was sincerely committed to social and environmental sustainability, prioritizing using locally sourced materials.
The Victoria & Albert Museum is set to present an expansive exhibition focused on Tropical Modernism, an architectural movement that emerged in the late 1940s. British architects Jane Drew and Maxwell Fry were instrumental in developing this approach, combining modernism’s functional goals with local climate adaptations in warm and humid weather. This movement, which embodies Britain's unique contribution to international modernism, evolved against a backdrop of anti-colonial resistance, blending colonial architectural principles with local needs.
On the 3rd of February, this year's Lagos Biennial opened at the Tafawa Balewa Square, Lagos, an emblematic venue that was once the site of Nigerian independence celebrations in 1960. As the 4th edition of the art fair, it continues with its objective of using art to activate historic landmarks that have lost significance either through functional use or symbolic meaning to the residents of the former capital city.
The home is a fundamental expression of architectural movements within the fabric of a city. As one of the smallest typologies, it is the simplest canvas to exhibit the design ethos of any particular era. African cities have continuously negotiated the meaning of their residential dwellings, from traditional architecture to colonial architecture, and the influx of post-colonial modern architecture. Vernacular architecture explored homes with spatial patterns rooted in cultural dexterity, envelopes built with indigenous materials and forms, endowed with traditional motifs. These were in stark contrast to colonial homes that featured a range of imported architectural styles across the continent, neglecting their climatic and cultural contexts while amplifying social class.
Buildings that are designed to layer stories and memories, evoke a sense of aspiration, define cultural narratives, and build a national identity will always be important in all societies. When buildings have this power to shape communities, make an impact on a city’s image, and change the course of socio-economic growth, then they can be identified as iconic. Though the term “iconic” is subjective, it is one that pushes the boundaries of architecture in any context. It calls for spatial originality, proposes innovative material technology, and necessitates a radical socio-economic investment to be realized.
Rammed earth is one of the oldest methods of constructing walls and still holds great potential for modern earth construction. One aspect of this potential is the gift of its colors and layers, which become visible as the formworks are removed, revealing a layered character. As a process that involves the layer-by-layer compression of gravel, sand, silt, and clay, its resulting appearance is a horizontal stratification of earth tones, material content, and curing procedures. This colorful appearance of rammed earth walls can be controlled and explored through patterns, texture, pigmentation, and natural clay colors, offering an opportunity to push its boundaries within architecture.
Tropical Africa boasts vast forests that cover 3.6 million square kilometers of land in West, East, and Central Africa. These forests provide valuable timber resources that significantly impact sectors, such as the furniture, fuel, and paper industries. However, interestingly, timber is seemingly absent in the contemporary architecture of the countries in this region. While architectural taste plays a role, the main reasons for this absence can be attributed to the wood industries' inability to meet the requirements of availability, affordability, aesthetic appeal, durability, and climatic and structural performance of timber. The wood industry in tropical Africa is mainly composed of informal and small-scale operations, focused primarily on sawing logs rather than refining wood for architectural or structural purposes. Despite this, the large number of informal enterprises in the region presents an opportunity to reshape the wood industry and utilize the local forestry resources to construct timber buildings.
African societies' cultures are intrinsically linked to color. From fabrics to clothing, products, sculptures, and architecture, various societies explore rich and vibrant colors that are vivid, expressive, and joyful. Through different shades, hues, contrasts, motifs, and ornamentations, colors are embraced as an unspoken language, a palette for storytelling, and a sense of cultural identity. Although the use of color in African societies may seem decorative on the surface, it is extremely symbolic, with a deep sense of history behind it. Traditional African architecture is a prime example. Ethnic societies have endowed their homes with color through ornaments and motifs, expressed it with religious and cultural patterns, employed it on facades to tell familial stories, and created labyrinths of communal architecture that not only celebrate color but explore its ethnic meaning.
Willow Technologies is a material research and building technology practice that has been selected as part of ArchDaily's 2023 Best New Practices. Founded by Ghanaian-Filipino designer and architectural scientist Mae-Ling Lokko, it operates in the gap between research, development, and diffusion of bio-based building materials. Working with agro-waste and bio-based materials usually incurs technical questions regarding scalability, industrial production, standardization, fireproofing, and mechanical strength. Exploring this data is where Willow Technologies situates itself, but peculiarly through the lens of developing regions in West Africa. Through comprehensive works with coconuts, moringa, rice, and other indigenous crops, Lokko’s practice has been able to investigate and catalog the material character of various crops, their possible by-products, local transformation techniques, and the prospect and challenges of scalability as building materials.
In the south of Burkina Faso, sharing borders with the northern environs of Ghana is Tiébélé; a small village exhibiting fractal patterns of circular and rectangular buildings, housing one of the oldest ethnic groups in West Africa; the Kassena tribe. With vernacular houses dating back to the 15th century, the village’s buildings strike a distinctive character through its symbol-laden painted walls. It is an architecture of wall decoration where the community uses their building envelope as a canvas for geometric shapes and symbols of local folklore, expressing the culture’s history and unique heritage. This architecture is the product of a unique form of communal collaboration, where all men and women in the community are tasked with contributing to the construction and finishing of any new house. This practice serves as a transmission point for Kassena culture across generations.
