The House of One

This paper explores the potential of the client-architect relationship to be part of a design methodology conducive to conceiving sacred space as collaborative, dialogical practice. The case study for this investigation is the multi-confessional project ‘House of One’ by Kuehn Malvezzi, currently on site in Berlin, Germany. The client for this project is not one cleric or religious community but a foundation initiated by a local Protestant, Jewish and Muslim congregation. The fact that the client is not one homogenous entity has shaped the conception of the project and consequently the building’s final appearance: all design decisions have been taken conjointly by the three clerics. In this project, the correlation between theological considerations and material realisation has been recognised as a reciprocal two-way process: theological doctrines are materialised through constructed space – equally, architectural questions can act as a catalyst for theological debate between the three clerics and their respective communities.
