Listed Buildings
Preserving history and building for the future.
For over 20 years, we’ve helped upgrade and preserve historic buildings and structures.
Behind every restored façade or reimagined interior is a team balancing tradition with technology, protecting the story while preparing the space for generations to enjoy.
At Delatim, we bring over 20 years of experience restoring, refurbishing, and upgrading listed and heritage properties, from King’s College London to Westfield Stratford, Shepherd’s Bush Station, and Bloomberg Place at Bank.
Heritage work is about more than compliance; it’s about respect for the architecture, for the people who visit it, and for the legacy it leaves behind.
When preservation meets progress, buildings gain new life and the communities around them thrive.
