Holy Trinity Church, Sloane Square

Glass Meeting Rooms, Glass Doors


Holy Trinity Church is located just off Sloane Square in the heart of fashionable Chelsea.


Internal glass doors; external glass doors; glass screens to create two structural glass meeting rooms


Built at the end of the 19th Century Holy Trinity is a testament to the Arts and Crafts Movement, containing treasures by some of the leaders of the movement, including William Morris and Edward Burne-Jones.

The church commissioned sound-proofed rooms to enable private meetings and to provide space for children during the Sunday service combined with new entrance doors to retain heat, exclude draughts and to provide an acoustic barrier against external traffic noise.

It was important that the project should reflect the Arts and Crafts heritage and that the new glass meeting rooms should provide privacy whilst at the same time allowing an unhindered view of the nave.

Technical Information

The new double glass doors are hinged from fixed side panels with a single glass transom panel above, stabilised internally with minimal glass fins. Each set of glass doors is designed to work in sync with each other to ensure that one set is closed before the other set opens and that left and right doors close together. Constructed from 12mm clear float toughened glass the frameless glass doors were supplied together with a full width arched overhead fixed glass panel, manufactured to fit perfectly into the original stonework.

Two meeting rooms are entirely constructed from structural glass, allowing an unhindered view of the nave. The glass screens are set into the original stonework with lateral bracing provided by partial glass fins. Frameless glass pivot doors provide access to each meeting room. The space was created from 12mm acoustic glass to provide a wholly quiet and private environment.

Due to the undulating floor levels and varying ceiling surfaces within the spaces, it was not possible to establish a datum for laser measurement, so much of the glass was manufactured from template. Shapes were taken of the stone corbels using a templating comb to ensure a precise fit. Ion also successfully pioneered a complex manufacturing technique on this project: offsetting the individual laminated panes by 10mm where the glass met the stone columns at an oblique angle.

Moving an original metal screen from the rear of the church to the front of the new meeting rooms retained the style of the Arts and Crafts movement, complemented by a decorative applied glass manifestation that echoes the motif in the screen.

  • The finished result meets all the requirements:  it makes excellent use of a previously under-utilised area of the church to provide sound-proofed, multi-functional glass meeting rooms retaining the Arts & Crafts ethos of the building without impact to the view of the nave. The glass doors work flawlessly providing a welcoming view of the interior of the building for visitors whilst retaining heat and excluding traffic noise and fumes.
