Ilot 13B, designed by KAAN Architecten, is located on the south-eastern edge of the first completed sector of the Rives de la Haute Deule development zone, overlooking the canal and bordered by four public roads. The project comprises four buildings and functions according to mixed-use principles, assembling offices and housing within one project.

The two residential buildings are to the south of the site, with 47 social housing units for rent and 23 units for sale on the open market . They stand out with their curving facades, which follow the sinuous line of the canal. The project dialogues harmoniously with the existing environment through the careful selection of contemporary materials, such as pale beige bricks, coloured grouting, natural anodised aluminium and glass. Protruding volumes, known as 'spines', are a modern reinterpretation of industrial bay windows and provide each apartment with direct views over the Deûle.

To the north of the site, the two office buildings buildings C and D provide extensive floor plans 800m2 and 420m2 respectively. Both buildings have been awarded 'good' BREEAM environmental certification for their energy performance. Characterised by pale grey glazed concrete facades with windows in bronze anodised aluminium, the offices reflect the beige tones of the neighbouring brick buildings.

The surrounding vegetation, consisting of a variety of ground cover plants, perennials and grasses, is typical of the Haute Deûle district and extends into the middle of the block. The green space on the ground level incorporates paved paths for easy pedestrian circulation.

The new neighbourhood of Rives de la Haute Deûle sets out to promote active circulation through carefully planned public space, both on foot or by bicycle. In keeping with this urban policy,Ilot 13B project encourages shared parking. Office parking is located in the neighbouring multi-storey car park, while residents' parking is within the block itself, in a private, covered car park on the ground level.
