East Africa features a range of diverse climatic, geographical, social and cultural conditions. In the absence of a definitive site, providing a model that can be easily adapted to local topographical and morphological conditions implies the development of a simple and flexible system.

The social and economic impact of the proposal is intentionally labour intensive: local communities can be actively involved in design and construction, reinforcing levels of self sufficiency and autonomy. Capacity building and the development of construction skills are added values made possible by this approach.

Sustainability and respect for the environment are an integral part of the design strategy: the use of recycled materials; sanitary ventilated pit latrines; the integration of vegetation; maximisation of natural ventilation and illumination; water and energy self-sufficiency are achieved by controlling the consumption of resources and, when possible, by adopting renewable energy sources.

The specific features of the proposed system are: a potential for and ease of expansion; an uncomplicated and rational aggregation that ensures basic principles of sanitation [separation between clean/dirty environments, sector segregation].

ADAPTABILITY

The buildings relative position will be adapted to the site VERTICAL and HORIZONTAL morphology

MULTIPLICATION

Buildings and walkways can be repeated following the grid, generating a new structure where before there was nothing.

STRETCHING

Buildings and walkways can be enlarged by stretching the modules to the new length. Stretching is permitted only when the size of a building allows for movement from one external space to another.

MODULES AGGREGATION

Geometry of the system is intended for easy replication and aggregation.

Typical arrangement is based on one walkway connecting two units.

The width of the walkways can be increased to meet shading/lighting requirements specific to local orientation and latitude.

The strategic sliding of modules can be used to create patios, increase natural illumination and provide views of the garden from the interior spaces.

BUILDING TECHNOLOGY AND MATERIALS

Besides rethoric, use what is available

Main building components [walls, roof, basement] can be built using a variety of materials, depending on local availability, climatic constraints, costs, etc.
The construction is not based on any one specific technology: the scale and typology of the proposed building module ensure make it possible to realize using a range of locally available building materials.
There will always be the issue to properly select adequate and appropriate solutions. Real flexibility has to do with the inherent possibility to pursue a specific architectural objective without depending on a specific material.
