This is a tradition of several centuries which goes back to the Turkish period in the 16th century, and is found both in housing, including several palaces, and in constructions in the suburbs. These constructions are found in groups in the medina (Tunis) or detached in the suburbs. They correspond to the type known as courty ard houses. The original inhabitants have practically abandoned the medina, which is now occupied by newly arrived immigrants, generally on a temporary basis.

Framework Bearing walls. Timber door sills and earth and lime floors. It also includes v aults and arches. Roof The roofs are generally horizontal, and there are very few sloping roofs. The roofs may be made of timber or vaults. In both cases, the exterior textural finish is identical due to the application of lime to make it waterproof. Rendering Generally a rendering of aerated lime mortar. By way of decoration: earthenware on the walls combined with marble, and plaster in bas-relief. In the courtyard house, the facades are on the inside. The outer walls are whitewashed. Openings and proj ections in the f acad e Very few openings in the facade. Appearance of compact walls with just doors opening in them, though the free facades of large residences do have other openings. In any case, this ty pology is designed and laid out so that all of the openings give onto the inner courtyard or patio where much of domestic life goes on. Traditional syst ems of air-conditioning Due to its location in a climatic area where the heat/sunshine hours/light vectors impose greater restrictions than the cold, this ty pology is geared to these conditions. The morphological density of the medina, the regulating role of the patio (a well for light, ventilation and passage) and the materials (earth, lime) used for roofs and for finishing (lime/whitewashing) contribute to the microclimate of the medinas and their houses. Drinking water supply systems Simultaneous use of the well (next to a wall in the patio) and the water tank . (beneath the centre of the courtyard to collect rainwater; it is still used despite the lay ing on of running water).

Beside houses which hav e always been maintained and occupied by dynamic family life, we find residences with squatters or which are simply abandoned in a dilapidated state. The ASM (Association de sauvegarde de la Médina de Tunis) has been working hard for years to revitalise the Medina of Tunis. TRANSFOR MATION PR OCESS Effect / Cause Since it attained independence, Tunisia has undergone a socio-economic and cultural evolution, intensified in recent decades. Economic development has led to an improvement of living conditions and a major population increase. Social evolution has been marked by the destructuring of f orms of community life as a result of the individualisation of economic production. This process has basically led to a change from the traditional patrilocal dwelling to the individual, so-called modern dwelling. Traditional architecture, characterised by the fixity of its forms, no longer offers satisf actory responses to new emerging housing needs. This has prompted designers to an ongoing search for a new, more adapted form of architecture. Typological transformations: . - Modif ication of the urban landscape in terms both of volume and of structure and spatial organisation. The causes are varied and not necessarily linked to the abandonment of certain traditional materials and techniques. The adoption of a new code of urbanism which edges out “introverted” architecture (courtyard house with no external facades) to introduce an extroverted type of architecture is one such. - Definition of new spatial organisations. Allocation of new spaces (bedrooms, living rooms, dining rooms, ...) and the break-up of the traditional patriarchal family (which grouped together the father and his married sons). - Improvement of sanitary installations and transf ormations affecting the kitchen and other rooms.Spontaneous superposition of two social uses of space (one traditional, the other “modern”. - Division of the traditional house and its transformation (after a fashion) into several smaller houses, generally rather disfigured.Break-up of the family and consequences of the laws of inheritance. Change in use: The f ormer owners leave the house which is then turned into an oukala1 or a craft workshop. Change of owner of the house or in owner’s social status. Abandonment of the Makhzen (store, warehouse). Change of owner of the house or in owner’s social status. Change in use of construction materials and techniques: — In use, living: lime (primarily used in limewash and to waterproof terraces, even in modern dwellings). - Little used, in decline: dressed stone (now used occasionally for strictly decorative purposes. Reinforced concrete and industrially produced brick and other baked clay products are being introduced. — No longer in use: dressed stone for structural purposes. - Recent incorpor ations: cement, reinforced concrete, steel and industrially . produced baked clay products. The reasons for this are economic (availability on the market) and psychological, even cultural (they are associated with modernity ).
