The Hanami project consists of the construction of a three-storey office building located at 11 Boulevard de Ratalens in Saint-Jean, on the north-eastern outskirts of Toulouse. The building provides flexible office floor plates that can be subdivided and adapted over time to accommodate a variety of professional uses. With a total floor area of approximately 2,700 sqm, the project was conceived with durability and adaptability in mind, allowing it to respond to evolving working methods and user needs.
The site is located within a heterogeneous urban environment typical of peri-urban business districts. To the east and south, low-rise craft and industrial buildings form the dominant urban fabric, while the nearby Union Clinic stands out as a major landmark in the landscape due to its larger scale.
The site is also characterized by a strong natural presence. A protected wooded area borders the northern and western edges of the plot, while a planted embankment to the south forms a landscape buffer between the site and the A68 motorway. This landscape configuration, combined with the site’s gentle slope descending toward the south and west, forms a key structuring element of the project.
Rather than opposing these conditions, the building’s layout seeks to engage with both the natural and regulatory constraints of the site. The building is therefore positioned toward the northern part of the plot, respecting the required setback from the motorway while preserving the existing green continuity.
The Hanami office building departs from conventional tertiary building references due to the geometry of the plot. The building’s massing is directly derived from the parcel configuration and the presence of the protected woodland. The structure develops according to a series of slightly offset parallel bands that follow the shape of the site while generating a dynamic architectural composition.
This layered organization offers several advantages. First, it maximizes natural daylight within the workspaces by multiplying glazed façades. It also allows the offices to open widely onto the surrounding landscape, particularly toward the wooded areas and planted spaces on the site. Finally, this volumetric principle creates variations in depth and relief that animate the façades.
On the eastern façade, facing Boulevard de Ratalens, projecting balconies extend this offset composition. These elements introduce a more domestic scale to the building while providing outdoor loggia spaces for users and contributing to the overall architectural expression.
The architectural language of the building is deliberately simple and legible, structured around a regular vertical rhythm. The façades are composed of alternating panels of natural-finish aluminium and glazed surfaces arranged on a 1.35-metre module.
This vertical grid gives the building a sober yet elegant expression while emphasizing the height of the façades. The generous glazed surfaces provide abundant natural light to the interior spaces and frame views of the surrounding landscaped areas.
The base of the building is expressed in concrete, while the façades combine aluminium and glass within a coherent chromatic palette. This continuity of tone reinforces the unity of the building and contributes to its integration within the surrounding environment.
On the roof, technical equipment is concealed behind galvanized expanded-steel screens. This system preserves the clarity of the architectural silhouette while ensuring the proper technical functioning of the building. The parapet, which also functions as a guardrail, forms the crowning element of the building and contributes to the balanced proportions of the façade.
Landscape design plays a central role in the project. More than 30% of the site area is maintained as planted open ground. The protected wooded area constitutes an important ecological reservoir that the project aims to preserve and extend.
Parking areas, located to the south of the building within the non-buildable zone, are accompanied by planted bands featuring local species. These landscaped strips help create ecological continuity between the existing woodland and the other planted areas across the site.
The project also preserves the existing trees while introducing additional planting. This landscape strategy strengthens the site’s green framework while improving the comfort and quality of the outdoor spaces. The overall landscape treatment subtly echoes Japanese gardens, which inspired the name chosen by the developer for the project.
Access to the site is provided from Boulevard de Ratalens. Pedestrians use an existing pathway through the protected wooded area, while vehicle access is ensured via a right-of-way across the neighboring parcel. The project provides 63 car parking spaces as well as dedicated bicycle facilities designed to meet current regulatory requirements and encourage soft mobility.
