Uncovering the story

WhereisLesotho?

Lesotho is in southern Africa. Maseru, Lesotho’s capital city, lies in the western region of the country. Despite being completely surrounded by South Africa, Lesotho remains an independent nation, however it onlygaineditsindependencefromtheBrisihin1966.

WhyLesotho?

I’vechosenMaseruinLesothoduetomykeeninterest in its culture and way of life. I also have a personal connections to the country, as my family has visited Lesothoandmyprimaryschool,Model,inCarmarthen, has links with the country, and I remember some teachers visiting the school when I also remember looking at my mum’s photographs and hearing about her degree research she did there; all this has had a lastingaffectonme.

WhoamIdesigningfor?

My idea is to create a building for the people of Lesotho, partly becasue it has one of the highest rates of crime in the world, and in 2023 was consdiered the most dangerous in Africa – measured by a country’s murder statistics. Therefore the people need to be given hope for the future and a place where they can celebrate and promote their culture, encourage the development of their skills and to have access to learningopportunties.

Understanding the people

Maseru is Lesotho’s capital and

city. Despite its small size, it has a rich cultural heritage and is known as the “Kingdom in the Sky” due to its high-altitude geography. The country is known for its traditional Basotho culture, distinctive architecture, and picturesque scenery, making it a distinct and captivating African destination (Sexton, 2023).

Understanding the surrounding context

The chosen site stands out notably for its expansiveness, particularly when contrasted with renowned sites as depicted below. Its substantial scale becomes evident, offering an intriguingcomparisonwithspecificlandmarks.

Sun radiation analysis study

Winter in Lesotho spans from June to August, when it is cold, and dry conditions, with temperatures dropping below 0°C (32°F) and frequentsnowfallinmountainousareas.

Conversely,summerfromDecembertoFebruary brings warmer temperatures ranging from 15°C (59°F) to 30°C (86°F). Despite being the rainy season, rainfall often occurs as afternoon thunderstorms, leaving mornings ideal for outdooractivities.

Responding to the environment

The site’s considerable size and altitude not only pose design challenges but also offer an opportunity to craft solutions tailored to the community and climate. Embracing these unique characteristics creates a platform for innovative, sustainable design that responds effectively to the environment and its inhabitants.

The history

Lesotho, once Basutoland, gained independence in 1966. Known for its stunning landscapes and rich culture, its history reflects resilience and unity amidst challenges.

Lets go back to the beginning....

MoshoeshoeI(Thepeoplesleadersince1831) invitedFrenchmissionariesfromtheParis EvangelicalFraternity toMorijain1842, and they establishedastationthere.

The aftermath

TheOrangeFreeStateBoersclaimedland fromMoshoeshoe, shapingLesotho’s borders.They tookcontrolinthe1840s-’50s, especially thefertileregionwestof the CaledonRiver, initiatingcolonial administration(DuvalSmith, 2010).

What happened after the war?

Desire to evolve

Lesothograppleswithunemployment, poverty, and infrastructuredeficiencies, promptingmigration. Challengesincludeskillsshortage, diseaseburden, andeconomicrelianceonSouthAfrica.

Responding to the surrounding context and the culture of the people is vital for this project, as numerous elements must be considered throughout the design process. Understanding the local context, including cultural traditions, architectural styles, and environmental factors, is crucial. By designing with the community in mind, we ensure that the project meets their needs and enhances their quality of life. From the layout of open spaces to the choice of materials and amenities, every aspect is carefully crafted to resonate with the local culture and contribute positively to the community'sidentityandwell-being.

Analysing the project on site

The new Lesotho government complex, particularlytheparliamentbuildingsitedontop ofMaseru’sMpiloHill,wasfunded,andbuiltby China.ChinaNortheastArchitecturalDesignand Research Institute designed the 43,273-squaremeter complex, which was built by China Yanjian Group. It houses the offices of the National Assembly, the debate chamber, the reception checkpoint, the accessory buildings, the parking lot, the open grounds, and the retainingwall.Thechamber’sroof wasinspired by the “mokorotlo style” design, a traditional Lesotho hat and national symbol that the Chinese have attempted to imitate. The 2012 building represents political functionality in Lesotho and has sparked debate about the politics and impact of Chinese-funded construction(InnocentBatsani-Ncube,2022).

Asthenewparlimentbuildinghasbeensitedon a mountain, it could be argued that this creates ideas of grandeur, authority and power. It is almost highlighting a division with its people, despite efforts for inclusivity. Although mainly modern, the building includes local influences. Financed by China, concerns about its sustainability and the politics of having the Chinesefundthishavearisen.Despiteisolation, the site encourages gatherings, suitable for proposedprojects.

Developing iterations

To make the site more lively and engaging, we need to create an atmosphere that encourages communication, teamwork, and intellectual exchange. This involves more than just changing the physical space. We need to thoughtfullydesignanenvironmentthatfosters exploration and engagement. However, the current design needs to be refined as it doesn't matchthescaleorformofthesiteeffectively.

The large-scale roofs did not serve any significant sheltering purpose for people. Although using thatched roofs was justifiable due to its association with vernacular African architecture, reusing this material was only symbolic of local building methods. Thus, it is essential to explore new materials to achieve sustainability and enhance building performance.

Ventilation strategy

In light of Lesotho's predominantly hot climate, the ventilation strategy stands as a pivotal aspect of this project. It is imperative to integrate a design that effectively optimises airflow to maintain comfortable indoor temperatures while fostering energy efficiency. Throughstrategicplacementofwindows,vents, and other ventilation features, the aim is to establish a passive cooling system that minimizes reliance on mechanical cooling, thereby reducing energy consumption and environmental impact. This approach not only ensures a comfortable indoor environment but alsoalignswithoursustainabilityobjectivesby promoting energy efficiency and mitigating greenhouse gas emissions, contributing positivelytoenvironmentalconservationefforts.

Responding to the environment

The window glazing system has been meticulously designed and incorporated with adaptable glazing to suit the environmental conditions. When temperatures rise, select windows automatically open, aiding ventilation. Furthermore, extensive insulation throughout the building design not only retains warmth but also prevents excessive heat penetration, ensuringcomfortableindoortemperatureseveninhotweather. Thisdual-functionalitypromotesenergyefficiencyandcomfort, aligningwithourcommitmenttosustainabledesignpractices.

Additionally,strategicplantingaroundthebuildingwillfurther enhanceitsthermalperformance.Treesandshrubswillprovide shade and block warm air, reducing the heat absorbed by the building and its surroundings. This natural cooling effect complements the window glazing system and insulation, contributing to a more comfortable indoor environment and reducing the need for mechanical cooling.

Interior views

Vibrant open spaces are vital for community well-being, offering places to relax, socialise, and enjoy nature. They encourage physical activity, support local economies, and host cultural events. Green spaces also provide environmental benefits, contributing to cleaner air, wildlife habitats, and urban resilience. They're essential for vibrant, healthy communities.
