Nantes, France
2005-10
Atelier d'architechture Christian de Portzamparc



Works to start in March and finish in the second trimester of 2010. Commissioned.



The project is incorporated within the urban plan of Alexandre Chemetoff. The construction layout of this large plot has been created to provide a public thoroughfare. It is composed of distinct buildings that are free standing, each one presenting a flat façade that is carefully aligned with the street, allowing views and light to pass between them. A large, raised garden overhangs the retail ground level.



This ‘Open Block’ layout – a concept developed and put in place in the 80’s by Christian de Portzamparc – aims to ensure that :

- This is a free-standing building volume, with its own identity and approach for each program : a hotel, a two star tourist residence, a four star tourist residence, three office buildings, local shops, averaged surface area commercial outlets, social housing that is dedicated to eventually becoming the property of its tenant. These residences are located along the Chemetov canal and have views over the Loire.
- A legibility of the block’s volume and boundaries along the avenue or canal, through the alignment of a portion of its facades.
- Alternating close and far off views from the buildings.
- Bright and sunny block interiors that maximise the brightness of the residences and luminosity in the street and canal by means of garden spaces and low rise constructions.
- Views from the streets and the canal towards the interior gardens and planted zones.
