Rewilding in a nature escape in Portugal

15 July, 2021 at 11:13

JDSA’s masterplan and design of a living in nature community in the heart of Alentejo got approved by the local authorities.


Combining Wild and Productive landscape in Alentejo.
How to turn 40 hectares of hilly land into a naturally diverse, rich and resilient community?
Constructing a series of buildings, laying out a few kilometers of paths and letting yearly hundreds of people visit and enjoy a precious piece of authentic Portuguese nature is an action that needs care. At Jardim, this will only be done with respect to nature.
Architectural interventions will be minimized, while outdoor living and taking care of the current vegetation and enriching the land’s fertility and diversity will be privileged. Jardim is a place to get in touch with nature, rewild, learn, discover and disconnect from urbanity.
Jardim will be an example of a future-proof, durable and socially sustainable community. The project has now received building permit and seeks like-minded partners.

The Bat Mansion is set in place

15 May, 2021 at 13:24

JDS Architects designed a birdhouse for bats in Parc Des Gayeulles in Rennes, France.

Near the lakes and forest areas of the park, a home for Bats was an obvious choice, as they are an important part of a functioning ecosystem. Making a bat-friendly place supports the ecologically essential role bats have in the environment, including pest-control, pollination and seed dispersal.
The Muz Yer project in Rennes made different architects design different birdhouses on various locations throughout the city. Each birdhouse is a specific architectural response to an urban context and a refuge specific to the species identified by the Ligue Protectrice des Oiseaux (RSPB in France), the project’s scientific partner.

The Golden House in Aarhus Completed

15 March, 2021 at 10:59


This spring, the first residents moved in our newly completed Golden House on the intersection of Vesterbro Torv and Vester Alle in Aarhus, Denmark. Having only one third of its façade length on the inner courtyard, we decided to reorient the project outwards, offering all apartments generous light intake and outdoor balcony spaces towards the city.

Belle-Île receives Building permit

15 January, 2021 at 10:55

The Belle-Ile project is an extension and renovation of a shopping center located between 2 waterways in the city of Liège, Belgium. 


The extension we propose turns the shopping center inside out. Rather than introversion, we suggest opening the mall to its surroundings, making the public space around the complex the heart of the project. The project cascades towards the Canal de l’Ourthe in a succession of landscaped and programmed open terraces. The program of the extension breaks with the monofunctional commercial space to offer a series of mixed functions such as co-working, catering and sports.

We’re happy to announce that we won the competition to design and execute a residential tower in Rennes.
Beyond the execution of this project JDSA will coordinate an ensemble of new buildings on the Blériot-Féval site to generate a mix-use and inclusive neighborhood within the Eurorennes development.


The development is located next to and comprises of the new station inaugurated last week. The city’s new express train connections have cut travel times to its neighbours and the capital by nearly half, enthusing many to develop business with or relocate to Brittany’s epicentre.

Within this Game Of Urban Thrones, Samsic, the region’s success story employing 90000, has set to relocate its headquarters to the Blériot-Féval site and steer its development, in collaboration with the developers from Bati-Armor and Rennes Municipality’s agencies.

The site is divided in 4 plots and coordinated by JDSA in collaboration with local architects Maurer & Gilbert and Paris offices SMAC and Think Tank.


The Féval Tower acts as the masterplan’s geographic and gravity centrepiece, offering 188 new apartments to the city. Our project promotes densification as a response to urban sprawl.

Our tower proposal manipulates the masterplan’s density to propose on ground level a stepped public space that invites the pedestrian to climb its base. Various commercial addresses will compose this base, on which the residential program grows from level 3, where the tower is most slender. Resonating Rennes’ colombage heritage, the tower thickens as it climbs upwards, to finally reach its maximum girth on level 10.


This is where a lush community park sets a pause to the rise and welcomes the building’s residents to a panoramic view of the city’s skyline under the shade of trees.

The building then resumes its ascension and profile all the way to its 27th floor, offering 184 new homes to Rennes’ residents.
