Together with colleague Luke Deering, Joni is currently co-leading the architectural design studio A347 – named after its London location: the North Arch on Beck Road – which showcased their first spatial project as part of London Design Festival 2024.

The project is a radical approach to the spatial typology of the community centre. Taking the neighbourhood's rich history in its contribution towards the arts, the North Arch acts on the agency of artistic practices, both in the production of and interaction with its outputs, in bringing people together, enabling and enhancing the vernacular culture of a community. 

The design facilitates the growth of individual artistic practices whilst supporting shared experience within a multipurpose courtyard, multiplying the value of creative culture through exhibitions, workshops, talks or other events.
