Since 2013, we have worked with our client Holy Trinity Development to transform Hull Minster. We were awarded the project through a national design competition and have supported the client to deliver three phases of development over a 10-year period. Holy Trinity is a 700-year old, Grade I-Listed church – the largest parish church in the country. Serious concerns over the financial sustainability of the church led to the inception of a Development Board and an aspiration to deliver a transformational project to safeguard the long-term future of the church within its community. The final phase of development was completed in late 2022 and concluded the 12-year project for the Minster. This scheme involved three phases including a reimagined public square to the west elevation of the Minster, a comprehensive internal re-ordering to create a flexible internal Nave to allow not only for modern services but concerts and other cultural events, and a new extension to the south elevation - The Trinity Room - which primarily accommodates a new cafe, servery and WCs, facing onto the square and can also be easily rearranged for use for events, worship and outreach. The new glazed Trinity Room, together with the transparent narthex, enables activity within the church to spill out onto the square as well as encouraging the community to enter the Church.
