The underground car park supports a shared courtyard garden that has a light feel because the building is raised slightly above ground level. Due to the density of development in the district, providing sufficient daylight at street level was a key design objective. Setbacks on the upper floors ensure good daylight conditions on the lower floors. Spacious outdoor spaces read as continuous verandas whose expressively designed ceilings make them feel like extensions of the interior space. From their private verandas, behind the veil that wraps the building like an orthogonal cobweb, residents enjoy views of the water just in front of them and of the centre of Amsterdam.

Outdoor spaces are vertically connected by a delicate grid that wraps the main volume like a veil. The grid is composed of 6-cm-thin balcony railings and 880 slender concrete columns. The latter are made of high-strength concrete (USHB) that can be shaped into very slim components, lending the building a stone-like appearance. The skin that wraps the apartments is articulated with vertical aluminium profiles that are anodized a light shade of gold. All apartments are reached from three vertical points of circulation, accessed via spacious entrances halls finished to a high standard with oak panelling.

The building contains a wide variety of apartments, depending on their position within the building. Equally notable is the sustainable range of materials used for The Line, ensuring it will enjoy a long life-span. Many facade components can be removed and recycled if and when required. The apartments are connected to a shared thermal storage installation, which provides cooling in the summer and heating in the winter. In addition, the shared garden contributes to biodiversity and the wellbeing of the residents.
