When I was scanning the images for the Kingsway Stores exhibition and recent article, I came across the Takoradi Kingsway in a colour slide. It wasn’t a building I was familiar with and hadn’t seen any other references to it within the wider UAC archive. The design is also different to the other branches – it doesn’t seem to fit with the earlier Millers (old Accra) or F&A Swanzy (Kumasi) stores – nor with the James Lomax-Simpson designs found at neighbouring Sekondi and Cape Coast. The branch at Sekondi complicates things further – why would there be a Kingsway at both Sekondi and Takoradi when they’re so physically close together? The Takoradi branch is also a substantial structure – far larger than might be expected for a town of this scale. Perhaps it was used as a warehouse or depot for the wider enterprise, receiving the imported goods from the neighbouring port that had opened in the 1920s, or was it used as a regional office and retail outlet for the UAC (or one of its predecessors) when the new town and port was set out? The archives include some replanning and refurbishment plans from the 1960s but nothing on the structure’s history and design. The neo-classical facade with ionic columns in antis is also unusual – contrasting with the more moderne 1930s turrets and cantilevered canopies.

I began to look at the maps of Takoradi to try to locate the structure, but couldn’t find anything on this scale – it was only when I reviewed my photos of the town that I found a contemporary image. The building is still standing and largely unaltered. It’s located amongst the other large European trading properties that were built around the customs house, train station and post office. There’s also shipping offices for Palm Line and Elder Dempster, along with a Barclays bank within this commercial cluster.
The latest edition of e-flux contains an interview with Joe Osae-Addo by Kwabena Appeaning Addo where they discuss Joe’s passively cooled house in Accra, Ghana.

Kwabena Appeaning Addo: What inspired your design for the Inno-native House in Accra, Ghana?
Joe Osae-Addo: My first thought was “How do I create a building that responds to the weather better than most,” so that I don’t have to use air conditioning? That was my primary focus. I then began thinking about the landscape, about how trees can be used as the first line of defense against heat, and also about how to position a building so that there is no direct solar gain. I was working in Los Angeles at the time, and I learned that the worst heat comes not from the sun, but through conduction from the earth, through the floor slab. So I thought to raise the building by about a meter, removing all direct contact between the floors and the earth, and insulating the building with a pocket of air. Those were my design parameters.
KAA: What happened when you took those principles onto the building site?
JOA: The site and the climate drove the initial layout of the building. After pouring the raised foundation, the first thing I did was to plant mature trees. I didn’t want to plant seedlings, because I wanted the trees to cover the roof by the time construction was done. So, I took a drive out of Accra to the area between Tema and Shai Hills, where there is a natural forest of trees. I went on a rainy day when the soil was wet, with a truck and laborers, and dug out mature—but not fully grown—trees, approximately three meters tall. We brought them back and planted them immediately. A year later, when the house was done, the trees had fully grown in. The ground also had a high water table, so I planted papyrus plants, knowing that they would suck up water. But even so, the site is very wet. On a rainy day, the concrete walkway in front of the house gets wet both from above and below. For the driveway, I used gravel, not concrete, to allow water to flow through and absorb into the ground when it rains. The landscape was integral to the design from the beginning. It is what allowed me to create a cool building.
KAA: What about in the design of the building itself?
JOA: Glass louvres are typically undervalued in contemporary Ghanaian architecture, but they are fantastic at creating cross-ventilation. Many of the exterior walls include glass louvers, at times from floor to ceiling. The rest are made either of laterite blocks or of timber frame walls joined with a tongue and groove system. The interiors of these wood walls are covered with stucco plaster, which makes it feels like a typical cement block wall, but on the outside it is clearly wood. This construction technique, known as Type V construction, is how most buildings in California are built: a 2×4 timber stud frame, 24 inches on center. In my case, however, since there is no air conditioning, there is no need for insulation. The third type of wall in the house, which I am very proud of, is made of wooden slats with a mosquito net attached. The wooden slats have a half-inch gap between them so that air can come through, but because of the net, insects can’t. The interiors are therefore always aerated.
KAA: So does it work?
JOA: Yes, it works! If we had air conditioning, the timber studs would let out so much cold. But because the diurnal temperature variation in Ghana is not significant, designing for cross ventilation works so much better.
KAA: Can you further explain how the walls were designed?
JOA: At the entrance, for example, there is a wall that looks like it is painted concrete block, but it’s actually just plastered. To do this, we placed half-inch plywood against the timber studs, and then placed chicken-wire mesh over the plywood as the support for the plaster.
KAA: So on the inside, it looks like a normal wall, but on the outside, it has a wooden finish. What is it like to maintain the house?
JOA: Well, I haven’t touched it in twenty years.
KAA: Really?
JOA: Well, there was some damage to the surface of the wood deck in the back, but that was because of poor detailing—I shouldn’t have used galvanized nails, which can rust and rot the wood. I haven’t had to repair any of the vertical surfaces.
KAA: That means that it must have been really well constructed.
JOA: Yes, it was. I built it myself, so I made sure everything was right.
KAA: It also means that the wood was treated very well.
JOA: At that time in Ghana, kiln-dried wood wasn’t available. All of the wood we used had to be air dried, so I picked the hardest wood available, which was called “Odanta,” or iron wood. It’s expensive, but I knew that maintenance would be a big issue if we did not use quality wood.
KAA: Does the fact that it doesn’t touch the ground also help?
JOA: Yes! Termites are often an issue if you use wood in Ghana, but this was solved by elevating the building off the ground.
KAA: At the Presbyterian Boys’ Secondary School I went to, some of the teachers’ bungalows were made of wood and they sat on the ground, so I can attest to this! Can you speak further about the laterite walls?
JOA: The laterite walls are composed of compressed earth blocks. I made the blocks myself with the standard cement block formwork. They are stacked and kept together using cement mortar joints, and then finished with stucco. To make the render, we filtered laterite through a sieve to get the finest particles, and added a bit of cement and water. After it dried, we applied clear masonry sealer to protect it from the rain. This generally works, but direct rain can still create damage. So I placed some vertical and horizontal wooden fins on the balcony, so that water does not hit the building directly.
KAA: Is there any benefit to using laterite blocks over sandcrete, which is more typical in Ghana?
JOA: I don’t know the physics of it, but sandcrete seems to conduct more heat than laterite.
KAA: In the middle of the living and dining space, the roof material changes to a translucent acrylic panel. Why is that?
JOA: I wanted to bring in some light. Most of the roof is made of long span corrugated metal, so it serves as a kind of skylight. I didn’t use Perspex because over time it would melt. This is about twenty-years old, and it’s still in perfect shape. Though it occasionally needs cleaning from above to make sure the light doesn’t get too blocked.
KAA: What about the floors?
JOA: The house has polished concrete floors. But the flooring is actually timber, because the house is raised. At the bottom is the timber frame, then, on top of that, plywood, then roofing felt, then chicken wire, and finally concrete, which is primarily made of quarry dust to get as smooth of a finish as possible.
KAA: I also noticed that the kitchen and dining room are lower than the rest of the spaces.
JOA: Yes, they are lower because I was following the topography of the site, which slopes downward. If they were kept at the same level, it would have been very inefficient. Besides, it makes for a nice transition from living room to dining area.
KAA: What about the spatial organization of the rooms?
JOA: Well, the house has no corridors. So you either move from room to room, or use the wraparound deck to avoid disturbing people in adjacent rooms. The reason for this is that when you have an interior corridor, it is difficult to maximize cross ventilation.
KAA: What were some of the challenges with the project?
JOA: Well, one challenge was finding the right carpenters. In Ghana, we don’t often use wood to construct buildings, so getting workers to understand the details and the drawings was difficult.
KAA: How did you address this?
JOA: I wanted to complete everything in twelve months. Since the laborers and artisans were getting paid a daily rate, the longer the process lasted, the more I would have to pay. But since I was the contractor, I could set up systems to speed construction. After we built two bays of columns, for instance, the carpenters I hired to build the timber frames started prefabricating columns, so that we could erect them whenever we needed them. After a certain point, the process of construction became one of assembly.
KAA: Based on your experience, what advice would you give someone who wanted to create a similar design?
JOA: Designers need to make sure that they’re not putting materials in places where they’re going to be compromised very quickly. And, in general, the use of metal should be avoided. Rust is a big issue, particularly in coastal zones. The marine air is corrosive. I used louvres with plastic frames because the metal would have rusted by now. And if you use wood, after it rains, it should be cleaned. No matter how high quality the wood you use is, keeping it dry is best.
Venice architecture biennale: how pioneering Ghanaian architects reckoned with tropical modernism by Kuukuwa Manful

But as well as looking at the future of architecture on the continent, visitors will also be able to explore its history, through an exhibition at the Arsenale, entitled Tropical Modernism: Architecture and Power in West Africa.
Early 20th-century modernism in Europe saw architects using large expanses of unshaded glass and flat roofs. Practitioners in warmer, humid climates, such as in Africa and Asia, meanwhile, had to adapt their designs to withstand heavier rainfall and warmer temperatures. In late colonial Africa and during the independence era, this style became known as “tropical modernism” or “tropical architecture”.
In the African context, this is possibly the best researched and well-documented architectural movement. When people discuss it further afield, however, it is mostly through a white lens. The focus is on what European architects practising in these regions were doing – African architects of the same era are largely overlooked.
Putting Europe at the centre of African stories is a choice that echoes the very colonial histories it seeks to elucidate, where European architects operated as though the continent were a blank slate, devoid of pre-existing architecture worthy of note.
My research shows how architects in Ghana in particular aligned with, adapted, or rejected Western colonial ideas. They created modernist buildings that reflected their visions for their nation, their experiences and their global outlook.
Ghanaian expertise
John Owusu Addo, the first black head of department of Ghana’s first architecture school, and Samuel Opare Larbi, another prominent educator and architect, embodied what I term the dominant Ghanaian tropical modernism. Their practice was most similar to, and aligned with, the practice of the white British tropical modernists.
The former Department of Tropical Architecture was established at the Architectural Association (AA) in London in 1954 by the British wife and husband duo Jane Drew and Maxwell Fry, and James Cubbitt. Although Fry described the city of Kano, in present day Nigeria, as a “complete realisation of urban harmony”, he and Drew nonetheless declared having “invented” architecture in West Africa. Their work was coloured by the imperial, racist and sexist notions of the time.
Owusu Addo and Larbi both trained at the AA. They counted among their contemporaries the German architect Otto Koenisberger and the Australian-born British architect Kenneth Mackensie Scott. Although they faced racial discrimination in Europe and back home, their UK education put them in a position of relative privilege in Ghana.
From the outside, many of the institutional and corporate buildings they designed, including Cedi House in Accra (a high-rise tower that now houses the Ghana Stock Exchange) featured elements of tropical modernism: solar shading devices, rhythmic facades, breeze blocks, cross ventilation and east-west orientation.
But it is in the interiors of their domestic architecture that their keen understanding of the people for whom they were designing becomes most apparent. When I interviewed Owusu Addo and Larbi in 2015, they recounted how they took Ghanaian societies into account. And they spoke of the pride they felt at being African architects.
For the Unity Hall student accommodation at the Kwame Nkrumah University of Science and Technology, Owusu Addo created shaded outdoor space, with courtyards and verandas. As he put it: “Rarely do we stay in our rooms in the daytime. If in the daytime anyone was in the room, then he was sick.”

Creative dissent
Other architects sought to establish an aesthetic that was visually distinct from European-driven tropical modernism. They accepted the climatic control and other technological and material aspects of the style. However, in the aesthetics they pursued, they were decidedly expressive.
Anyako-born architect Daniel Sydney Kpodo-Tay’s confidence was grounded in his centuries-long family history of building design and construction. Together with his anti-colonial politics and a desire for recognition, this informed an approach that the Ghana Institute of Architects termed “revolutionary”, upon his death in 2018.
Kpodo-Tay was fascinated by symbolism. His designs rejected ornamentation. Instead, he sought to make the buildings themselves sculptural. His projects that were built were often not as bold as his proposals – a compromise he put down to the limited finances and conservatism of clients in Ghana.
When a competition was held, in the late 1980s and early 1990s, to design the headquarters for the Economic Community of West African States organisation, Kpodo-Tay’s proposal drew on the form of a bowl as symbolic of communality and unity. His design for the complex, which was to house offices, a bank and a conference venue, featured bold inverted conical forms with internal spaces arrayed radially.

Owusu Addo, Kpodo-Tay, and Larbi are not the only Ghanaian architects of their generations whose practice was informed by tropical modernism. Many stories are yet to be brought to light, especially those of the women.
Only a few women were trained at the Kwame Nkrumah University of Science’s architecture school. Sexism in the industry saw some leave. But others, including the late Alero Olympio who designed Accra’s Kokrobitey Institute, struck out in bold new ways. These visionaries challenged the Euro-centric assumptions of what tropical modernism was, in particular through their use of materials.
As scholars, practitioners and visitors from around the world turn to architecture on the African continent, they must be careful not to treat it as a blank slate in the way previous generations did. Africans have been creating, studying, teaching, and documenting architecture in Africa since time immemorial. Their work matters.
The Transnational Architecture Group is 10 year’s old this year. Thank you for supporting the blog and to all of our excellent contributors over the years for enriching the content and generously sharing their work. We’d also like to thank the communities in the places in which we work, the archivists and librarians for making material available to us and sharing their expertise, our respective institutions for supporting our research, and to the research funders who make travel, time, and resources available to us.
The blog started as a means to share our work-in-progress ideas and to promote events – and that is still at the core of what we do. We continue to add updates from our ventures into the archives, travel reports, and to share interesting events and innovative papers. These small reports and updates have compounded into something of a large resource and repository, and we’re delighted so many people have been able to make good use of (and to correct and expand upon) our work and attempts at writing these histories.
To celebrate the 10 year anniversary we held a small gathering at the Liverpool School of Architecture on Wednesday 8th March, curated and organised by Dr Alistair Cartwright. Our speakers were all PhD students, post-doctoral researchers, and research associates at the school. You may watch the proceedings here:

The 1951 victory for Kwame Nkrumah’s Convention People’sParty resulted in some major shifts in the procurement of new infrastructure and housing. For the electorate, housing was one of the most important issues and Nkrumah’s government was quick to recognize this potency.
His plan, announced in 1952, was to build a new port city, complete with innovative and improved housing at the highest standards. Located only 18 miles from the centre of Accra, the new city of Tema would demonstrate Nkrumah’s commitment to industrial development and that Ghana was at the centre of a pan-African vision.
Tema under construction: female labour force transporting blocks and cement
Tema was part of a wider industrialization project that included a new aluminum smelting plant and hydroelectric power station on the Volta River. It was a major project involving international financial backing and set out the major ambition Nkrumah had for the nation during the advent of independence. For such a major project, very little is known about the first team of architects and planners responsible for the execution and delivery.

Maxwell Fry, the architect and planner of Ibadan University, considered the campus to be the highlight of his career, although he confessed that he found the Kenneth Dike library elevation too ‘lace-like’.
It is an extraordinary structure and we’ve covered it on the TAG blog previously, as well as printing a 3D sectional model of the structure. Taking a more retro step, I’ve now produced a hand-drawn (rotring, ink wash) front elevational drawing of the building (minus the small reading room on the RHS and smaller structure on the LHS, for clarity).

The drawing stretches over 2 x A1 sheets and has been scanned, pieced together, and the blue ‘sky’ added in Photoshop. I’m going to follow drawing with some additional studies into various libraries in Ghana – especially the Children’s Library in Accra (Nickson and Borys); Sekondi Regional Library (James Cubitt); Koforidua Library (also by Cubitt); KNUST Library (?) and the iconic Bolgatanga library by Max Bond.
Ghana’s housing – an historical retrospective.
Ola Uduku writes:
Visiting Ghana gives one the chance to step back through time – there is an abundance of housing which has survived the vicissitudes of the temporal, physical and socio economic life of more than fifty years; and in certain cases an entire century of existence in the unforgiving tropical climate which comprises much of Southern Ghana’s landscape. In two weeks we came across these special gems.
Timber housing: Colonial Ghana, then called the Gold Coast along with Nigeria had significant swathes of forests which were sources of tropical hardwood. The Colonial government established significant agro-forestry concerns in both countries, which resulted in timber research stations. The two houses in this post are examples of experimental worker housing that these research stations were responsible for developing. We think that the Kibi house, near the market town of Koforidua, is over one hundred years old. The other lapped wood house was found at the Aburi botanic gardens, which had previously been the site of a sanatorium. Interestingly both buildings have substantial elements preserved including; walls, casement windows, wooden flooring and roofing elements. Generally only the non ‘wood’ roofing sheets have had to be replaced.

Forestry Housing in Kibi
Brick Housing: At Kibi also across the road from the ‘forestry’ house we found an example of a demonstration brick building. This was a semi detached pair of worker quarters set out as a single depth bungalow with a wide verandah and walls one brick thick. The first building retained the balcony format whilst the second had its balcony appropriated to create more space for the larger families who now occupied these buildings.
Experimental Brick Housing in Kibi
Impregilo Prefabricated Housing Going to Akosombo Community One – which was where the elite staff and also the contractor Impregilo had its staff quarters revealed a further rare find. Built on a higher part of the Community One hill ridge are the original staff quarters for Imregilo staff, we assume these would have been for the Italian foremen and remain in near pristine condition. The original prefabricated lightweight wall-panels can be seen clearly in the neat avenue of houses which looked in some ways like a re-created Italian village scene. A number of the houses had the individually built ‘sit out’ verandah areas with views to the Akosombo landscape and the staff club below.

View of the Akosombo Dam from Community 1
Today’s domestic architecture in Ghana as in much of West Africa unfortunately seems to have not incorporated much of the ‘environmental design rules’ that these and other residences of this early post independence era were able to employ. The site orientation, use of lightweight materials, utilisation of large areas of operable fenestration, and shading, have all contributed to make these now historic houses exemplars of how domestic buildings could be built to ensure thermal comfort without reliance on today’s ubiquitous air conditioning systems. Surely it is now time to re-evaluate the principles so aptly demonstrated in these houses and use them as a basis for developing a more sustainable response to tropical housing in Africa today.
As part of our British Academy Internationalisation and Mobility grant Iain Jackson and Ola Uduku visited Rexford Opong at KNUST in March (we included some brief updates here: Notes from Kumasi and Notes from Kumasi: part 2 and also Notes from Kumasi Part 3). We were fortunate enough to visit the Estate Planning Department and drawing offices and photographed some of the original drawings made of the university estate and buildings. Whilst every effort is being made to carefully preserve these drawings they have been subject to the ravages of time, humidity and vermin attack and many are in a poor state of repair. They are unlikely to survive for much longer.
Drawing of the First Floor Senior Staff Club House, KNUST
In an attempt to remedy and counter this we are putting together an ‘Archives in Danger’ grant that, if successful, will enable these important artefacts to be digitally scanned/carefully photographed and then carefully preserved and archived for future scholarship.
In the meantime we’ve used the photographed drawings to produce a series of new CAD files. Pedro Bittencourt, a student based at Liverpool School of Architecture, has worked dilligently on translating the imperial scales into a metric format and has produced all of the new drawings. He has then used these drawings to construct a beautiful scale model of the Club House, utilising a laser cutter as to form the delicate components.

We’re hoping to produce additional models of other buildings on campus that can be used in exhibitions and as part of our lecture series.
The Architecture of Edwin Maxwell Fry and Jane Drew:
We’re delighted to announce that our Fry and Drew book is to be published in paperback format in a few days time. This should make it a little more affordable and hopefully accessible to a broader audience in West Africa and India…
