这是由Coldefy & Associés Architectes Urbanistes设计的植物园。场地区位重要，位于里尔的经济中心区，提供居住、商业、办公等混合功能，其项目将提升该区的生活质量。

项目包括两部分，沿着保罗林荫大道的、建筑面积达2800平方米的办公室，以及毗邻住宅区的、可提供68个单元的住宅。建筑底层层高5.6米，可提供900平方米的零售商业空间。这些零售商业空间 （内部分隔为150-300平方米的小空间），可直接从街道进入。此外，局部空间设有夹层，辅以服务设施。

公寓能享有两面或三面开窗，主要生活空间设有宽敞的户外空间。建筑外立面呈现多样性的生活方式和多户型的公寓单元特征。较小的公寓单元集中在一起，并可通过一个楼梯连接到花园。而较大的公寓对着户外，阳台种满了植物。有些窗台为两层高，有助通风散热。

建筑外墙采用了简单的材料：砖。其矩形形状排列形成建筑外墙的几何分解，而白色的色调塑造棉线编织的形象。外墙为绝缘材料，并设有太阳能电池板，可为居住单位提供50%的供热能源。建筑使用的生物气候设计，有助降低建筑物的能源消耗。

Symbol of rebirth of a neighborhood, the Arboretum project is a continuation of the development along Hoover Boulevard and the very metropolitan Euralille 2, articulating of the future Porte de Valenciennes neighborhood.

This strategic position induces a sense of transition from the economic heart Euralille to the mixed-use neighborhoods of housing, commercial, and amenity programs, in which the quality of life takes precedent over monumentality. The project marks a step, an initiation, a hyphen between two neighborhoods.

The ground floor serves as a base of 5.60 m that unites the composition into a coherent whole while providing 900 m2 of retail space. These retail spaces (divided into cells of 150 to 300 m2) are all directly accessible from the major boulevard with the most pedestrian traffic. Additionally, certain spaces contain mezzanines that allow for specific layouts of service programs, for example.

Grid and Module

The facade on the boulevard takes the form of a grid of an infinitely extensible module. Applied as a “plug-in”, it responds to the function within, expanding to form loggias or expanding to develop a double height – exposing the duplex apartments that form the “skyline” of the block. Sometimes taut, sometimes porous, the module allows all functions to coexist harmoniously, revealing only the texture of its material.

The front wall inflects when it encounters the opening that becomes a vegetal void. This void creates an open space at the heart of the programs, a link between the two towers, demonstrating an attention paid to nature in a global effort of neighborhood densification.

Composition and Organization

The breakdown of the program allows one to consider the articulation of the different entities around four rational, identical volumes whose base dimension of 18 m x 18 m strengthens the cohesion of the elements and the identity of place. This supports the concept sought after of gathering. The plot is in fact seen as singular entity with a unit of treatment. There are no secondary facades, but a variation of the base unit in reaction to a specific exposure or a particular situation.

Offices, shops and activities are divided between the pedestal of the whole project and the tower positioned at the corner of Boulevard and the new street. For their part, the housing benefits from a square layout with a central circulation core. Almost all apartments benefit from double or triple orientation. The main living spaces are provided with large exterior spaces, whose specific articulation is defined by the character of its exposure.

In their diversity and implementation, these exterior extensions highlight a multiplicity of life styles characteristic of multi-family housing. The smaller units are grouped in threes with a common staircase connecting them directly to the garden.

The larger apartments have a generous exterior loggia on the principal façade and balconies in the vegetal void. Sometimes a double height loggia is complemented by a bay window allowing ventilation towards the void and passive heating on the facades with optimal exposure.

Materiality

The general envelope of the assembly is made of a material of simple construction: brick. Its rectangular shape continues the geometric decomposition of façade module. White in color, it evokes the weaving of cotton thread. Its implementation shows that the simple basic module can generate freer forms than those which had been initiated in the postwar industrialization of building systems, whose image is still associated with the area.

The compact and efficient massing of the project, a comprehensive bioclimatic design – particularly, the insulating envelope and ventilation – and specific interventions – solar panels intended to provide 50% of the hot water for the housing units, and air chimney in offices – helped qualify the building as low energy consumption (BBC), as desired by the client Nacarat.
