Community Centre for the experience and exchange of Congolese culture in Yeoville

2020

PROJECT DESCRIPTION

“It is important that we know where we come from, because if you do not know where you come from, then you don’t know where you are, and if you don’t know where you are, you don’t know where you’re going. And if you don’t know where you’re going, you’re probably going wrong.” - Terry Pratchett. This research is rooted in my experience of being a migrant in a foreign land and it is birthed from a desire to maintain my cultural identity. Four words drive this research, each dealing with specific themes: Congolese: • Migration Community: • Cultural diversity and inclusivity • Self-sufficiency

Culture: • Sustainable development • Cultural Identity Cuisine: • Food • Urban Agriculture • African Leafy Vegetables

This led to a research project based on the question: How can a migrant community still experience and exchange its culture in a home away from their own? The project aims to deconstruct a xenophobic mentality and create a sense of belonging for certain migrant communities through cultural awareness and inclusivity. Food is used as a platform in promoting culture for sustainable development, with African leafy vegetables forming the base due to its inclusive nature in being eaten across all African nations and its ability to be farmed in small spaces using diverse farming systems. The community centre serves as a medium through which the Congolese culture can be experienced and exchanged and is a catalyst for strengthening diverse multi-cultural communities in Yeoville.

CONCEPTUAL THEMATIC

The community centre is a built interpretation of a traditional African mask. The building form resembles that of a crown and the building’s sharp-pitched and folded roofscape is its crown. The traditional African masks connect to rituals and ceremonies around harvesting as they ensure a good harvest. This connects to the building’s farming and planting programme. Furthermore, the anatomy of African leafy vegetables consists of the roots, the stem, and the green crown of leaves on top. This green colour is reflected within the building and on its facade. The traditional African masks are mainly carved from wood, however, terracotta, pottery, copper, brass or leather are among secondary materials used. These materials are reflected in the building’s architectural language through its terracotta satin facebrick facade, timber screens and planters, and its timber roof structure. The colours of these materials are also reflected on the building through the copper-coloured roof sheeting, the warm, terracotta-coloured facebrick and black steel plant trellis screens. The geometrical and symmetrical patterns on the building’s elevation reflect the use of bold patterns incorporated in the design of traditional African masks, which identify female and male masks or serve as a form of coded information. However, in the context of the building’s design, these powerful and expressive patterns function to draw positive attention to migrant communities, allowing these communities to be visible, celebrated and deeply rooted within their local contexts. The building is intended to draw attention to itself through its architecture and is an icon and symbol which gives a new mask or identity to migrant communities, with the aim of deconstructing past and present negative conceptions of migrants or “others” within Johannesburg, and deconstructing a xenophobic mentality by firstly being a space where migrant communities can feel at home away from their homes, and secondly by sharing diverse cultures with its local context.

SUSTAINABILITY

Passive design techniques implemented throughout the building for optimal plant growth. The building responds to its orientation by having plant and timber screens on its west façade and deep-set windows and roof overhangs on its north façade. The plant screens grow on steel trellises which are supported by the facebrick building façade. It makes use of passive cooling techniques through roof gardens and the courtyard towards which most spaces open. Air can move through, making the spaces cool and well-ventilated. The peaks in the roof structure allow for stack ventilation in big spaces like the cooking workshop and multipurpose hall.
