4 and 5 Crucifix Lane London, UK

Originally designed by Charles Henry Driver (1864-1866), the arch was part of Jacks nightclub, where the Chemical Brothers debuted in 1994.

SGP’s design brought a light, bright and fresh feeling to the two floors, creating efficient office space, flexible training rooms and streamlined support amenities.

The project preserved the original polychromatic brickwork, stone carvings, and window openings while integrating modern security shutters internally.

Works included re-lining arch spaces, installing insulated floor slabs, and adapting the drainage system to incorporate Victorian buttress structures.

The project is a key part of The Arch Company’s £200m Project 1000, aimed at repurposing 1,000 disused spaces across England and Wales.

“When we took over the portfolio in 2019, we sought to invest in bringing 1,000 spaces just like this arch into use, as part of our £200m plan Project 1000. As a restoration project, Crucifix Lane is a particularly exciting as it is such a striking space, set in an excellent location. We look forward to welcoming a new business into the local area.”
