ALTSTADT


... is the collaboration between Jan de Moffarts and Steven Bosmans, and as such the new name of JDMA. JDMA was founded by Jan de Moffarts in 2016, with the project for the restoration of the Gare Maritime at Tour & Taxis. Since 2018, he was joined by Steven Bosmans, one of the former principals at OFFICE KGDVS, as a conclusion of a period of occasional collaborations. Based at Gare du Nord they are working on diverse projects ranging from heritage reconversion to new construction.

As a collaboration and a studio, ALTSTADT seeks to combine a specific know-how in the restoration, reconversion and re-activation of historical buildings, with a skill, or perhaps obsession, for methodical and conceptually precise design. Heritage, as a built presence of the collective memory and therefore essentially public space, is a central theme but not a focus. The main ambition is making spatially precise, clear, and sensible projects, independent of the origins and scope of the project, with radicality and subtlety as alternating and mutually reinforcing intentions.

Within this framework ALTSTADT is working on projects and studies of all sizes and origins in Brussels and beyond, notably the restoration and extension of a historical rectory in Brussegem, a mixed-use industrial complex in Merchtem, the reorganisation of accesses to the Tour & Taxis park, the restoration of a castle near Namur,  the reconversion of the Vynckiersite in Gent and the competitions for several cultural centres in Brussels. Collaborations with other practices, such as OUEST, 51N4E, NU architectuuratelier, ORG PER MOD, OFFICE KGDVS … as well as with academic institutions such as KUL and VUB, are an essential part in the web of activities. In these, ALTSTADT alternates between the roles of designer and advisor.
