257_LOT 0 Lens, Lens, 2019-24.


The project, a series of three distinct volumes characterized by different heights and set back from each other, stands as a direct reaction to its surroundings.
On the south-east of the plot, the first volume lines up with the neighbouring building, a former medical office at Lens station, and sets in motion that subtle play of cusps towards rue Jean Létienne that culminates on the north-west side, in alignment with the adjacent mixed-use development.
On a programmatic level, the project proposes a horizontal partition into four layers: the basement is intended for parking; the ground floor houses the reception halls of the training centre, offices, the shop for the transport company as well as a café / restaurant; the upper floors accommodate the premises of the training centre and offices.
By virtue of its programming and location, the ground floor enables the bordering public spaces to be activated through both a fifteen meter wide urban breakthrough connecting rue Jean Létienne with the bus station, and a covered gallery offering shelter to public transport users.
Lastly, the project's stepped volumetry and the integration of techniques into the building envelope free up large sunny outdoor areas for the occupants to enjoy, while the wooden structure and aluminium cladding give shape to an elegant and light ensemble.

We're glad to share our proposal for the recently concluded Tirana Faith Park competition!

Thank you to our great team and to the organisers and , with the support of the Miral Group.


The creation of the Faith Park is the opportunity to add a piece to the already astonishing landscape of the Erzen River. A place dedicated to coexistence, dialogue, integration and exchange where faith, nature and heritage intertwine in complexity and harmony.
Faith Park is about multiplicity: contemplation and celebration, intimacy and exposedness, dedicated and common spaces, heritage and present-day artefacts, spontaneous nature and formalized gardens, unbuilt and built, existing topography as well as infrastructural interventions. These apparent opposites coexist and find correspondence in this layered (land)scape.
The creation of the new public park becomes the opportunity to start a needed process of care: the landscape will not only be consolidated and preserved but also enhanced by the infusion of public program.
In this framework, our proposal is based on a series of layers, composed both from qualities and challenges of the existing condition and the numerous new interventions.
The layers of this ‘multiplicity’ are structured on a common framework: a grid virtually and physically projected onto the site. The resulting checkerboard celebrates encounter and coexistence by generating conditions that allow maximum exchange and flexibility between objects, surfaces and trajectories. The initially orthogonal grid reacts to the slope partially abandoning its orthogonality. In one direction (North-South), straight lines climb up the slope in the form of stairs, paths and ramps; on the opposite direction (East-West), the curvy topography lines take over. This deformation of the grid not only settles accessibility issues but also allows for a subtle integration or natural and artificial.

352_Marseille Olives, Competition, 1st Prize, 2025.

XDGA and are happy to announce that we have won the competition for the design of a primary school and sports facilities in Marseille!



Les Olives, formerly a village, is now a residential neighbourhood in north-east Marseille. Here, a new school is being planned as part of the city’s “School Plan” to modernize facilities, accommodate growing student numbers, and support urban renewal. The site currently hosts a gym, a refectory, a caretaker’s lodge and a 1960s prefabricated school building. Rather than demolishing the latter, the proposal aims at reusing it as a large covered hall and playground, offering both shelter and privacy for the nursery area. The outdated gym will furthermore not be refurbished, but will serve as an open air playground for primary school students.
The new project is designed to optimise outdoor spaces, mark the entrance to the site and allow for construction phasing without modular installations on site.
The layout consists of three volumes, each dedicated to a specific use (1. Gym, administration and extracurricular activities areas; 2. Classrooms; 3. Dining and caretaker accommodation) and connected by covered, external circulation routes.
The architecture ultimately features load-bearing facades in cut stone and a mixed structure combining stone, wood, metal and concrete, following the principle of ‘the right material in the right place’.

Sharing some material from our first competition in Oman!

-

This project began with the discovery of an unfamiliar site that nevertheless resonated deeply with our past work in peripheral, transitional landscapes. The brief was concise yet ambitious: to create meaningful architecture in a fragmented urban context between a highway and a commercial complex in the outskirts of Muscat.
The proposal articulates the dual program hotel-office through a cluster of three interlocking cubic volumes wrapped by a shimmering stainless steel curtain and anchored to the ground by a continuous, rammed earth plinth.
Climatic and cultural references rooted in Omani vernacular permeate the project: a shaded courtyard (Sahn), a covered gallery (Liwan), an atrium (Adin) and a covered entrance (Riwaq) assure passive cooling and comfort.
Ultimately, the Oman Diamond stands as a landmark: iconic, contextual, and climate-responsive.

Happy to share some pictures of our recently completed project 'Citydox' in Brussels.



The project superposes a programme of productive activities and housing; in between, on the first floor, an intermediate layer of parking acts as a "buffer zone" between the two.
Not only does this respond to a high groundwater table, yet it protects residents from possible nuisances caused by the productive activities on the ground floor and provides both functions with a potential flexible space for future expansion.
The project furthermore sets out a set of urban principles aimed at creating coherence between the three plots present on the site on the “macro” scale, while preserving their diversity on the “micro” scale. The respect of the building envelopes and the position of the volumes on the plinth ensures, in fact, harmony between the three towers facing the canal, while the individual expression of the facades allows for readability of each element.
This very principle is ultimately applied to neighbouring plots as well.

The client for this building is a car import and dealer company that is fully aware of the deep change and uncertainty the automotive sector will be facing. To put it mildly, electric cars need less maintenance, showrooms are being replaced by websites and the sharing economy is taking over ownership in favour of mobility as a service. Despite this, a very large car workshop and showrooms for different brands are still part of the program, as are a series of productive spaces that will complement the nature of this dynamic neighbourhood situated along the Brussels Canal. What is needed here is not so much a building that can be endlessly adapted to new uses, but a structure that can accommodate any activity; a building type in which landscape, urban density, logistics and architecture merge into one is therefore proposed. On the inside is a rational, high-load bearing concrete structure with 16.2 meters floor spans and a height of 7 meters to which, if needed, intermediate steel floors can be hung. On the outside, on the other hand, the sturdiness of the structure is balanced out by the curvy, transparent façades (glass on the south-east side, steel cables and mesh on the north-west side) resulting from the movements of cars and trucks on site, the bending of the main road and the amorphous boundary of the plot. A series of patios and atriums ultimately pierce the large volume providing the space and quiet that are lacking on the outside.
