incremental house

Next to the half Chowkinuma house, amidst a large galgal tree, one sees a house under construction.  Three houses in its vicinity are completely rebuilt while one of them is in the process of being reconstructed with only a RCC skeleton and a plinth currently in place.  Parts of the old half chowki house abuts it with a kitchen below and a room with a verandah above. The Sharma family owns all four spaces. The idea of incrementality is evident here as the family builds a new house as it grows. This allows the new members of the family to have their own spaces in close proximity to the extended family. This building activity also happens in parts, as and when the family has the adequate funds and material for completing a certain part of the construction. This never takes place at one go. The current state of the building, with the RCC skeleton and a plinth has made the space into an open pavilion in the midst of the rest of the family spaces. People from the Sharma family spend time doing multiple activities here. The space also becomes a centre for recreation for  the entire cluster. Women from the neighbouring houses spend their afternoons together while the children use this space for either playing or studying. The porosity of the incomplete house creates multiple affordances as the space is used as an outdoor living room shaded from the harsh summer sun. Perhaps when this house is complete ideas of privacy, permanence and completeness will take over as opposed to the porosity, impermanence and incompleteness of the present space, which makes it a dynamic social space. How can contemporary architecture create conditions for such a space to operate?
