The Grand Large district has been designed to take into consideration a special urban context: inserted between the city and the sea, between seaside resort aesthetic and port aesthetic, and between typological variation and collective space. It extends the overall strategy of the Neptune project, launched in 1991, which aims to reorient the city towards the docks. This transformation of the urban centre has already been broadly achieved. The Grand Large district marks the start of the second phase of Operation Neptune, which focuses on sustainable development.
The 216 homes which make up the first phase exemplify the ecological dimension that has been adopted for a district that will eventually consist of 800 to 1000 homes. The district’s strategic urban plan is based on the principles inspired by Agenda 21, notably in terms of its social (diverse social mix), environmental (rainwater management, renewable energies) and economic aspects (flexible product use and operational phasing).
The Grand Large district brings together different building types and includes public spaces on diverse scales: a semicircular park with individual houses; the quay with gabled buildings; the apartment buildings with green roof terracing and finally the crescent gardens at the heart of the individual lots
This diversity of building types and the social mix which this encourages generates a lively neighbourhood which creates original perspectives: the view of the Grand Large Hotel from rue Degans, the green aperture looking towards the planted ramparts, and the views of the gabled buildings from the quayside.
The Grand Large district has an environmentally sustainable design and features wind breaks as well as rainwater management systems through a system of roof valleys and park water catchment. The buildings are designed to be energy-efficient. Priority is given to pedestrians, with motor traffic limited to access roads. Only the Avenue des Bordes is treated as an urban boulevard.
