The development organizes the project using the site topography as best as possible and avoiding as far as possible impacts on the site's geo-morphological structural elements. In fact, the project is divided into three "lines" (the PSLA dwellings in the upper part of the site, and the LLS dwellings downstream), positioned as well as possible on the curves of the topography in order to limit the cuttings/fills, and distributed by paths with gentle or horizontal slopes. In addition, the slope is also used to create parking lots under piles that are substantially buried, facilitating the capacity and distributive simplicity of the plot by vehicles.
The architecture developed is of the "small townhouse" type, thus making it possible to envisage a constructive dry solution that will be very favourable to thermal comfort, avoiding problematic emissive materials such as concrete.
The design of the dwellings is also based on a bioclimatic approach taking into account the coolness of the climate of the windward coast, in terms of through ventilation, solar protection adapted according to the orientation of the façades, insulation of the exposed walls, and winter and mid-season heat gains.
In addition to the work on the relationship with public space and housing design, another important feature of the project is the work on the gardens. The interpenetration and dimension of the garden are essential to the quality of life and climate of the operation. The strategy for choosing the plantings must also be carefully thought out, in line with the local microclimate and the need for easy maintenance. The strengthening of private gardens aims to promote the domestic lifestyle of the vernacular district, while the collective gardens positioned at the centre of the LLS operation will be treated in such a way as to delay rainwater.
