St James Square is a residential development adjacent to and within a Grade II* listed office building which was originally built in the 1700s for William Wentworth, 2nd Earl of Strafford. With developing adjacent to and within a building with statutory protection comes many complexities which require careful consideration, especially at the interfaces between the existing grade II building and the new main façade.

The project consists of 6 floors as a mix-use building with 13 high end apartments. The façade surface area was 1,000m2 of vertical hung Dural Limestone supported using the RJ Facades U-brackets and box sections with a horizontal profile and clasp system connected to the Limestone using FZP undercut anchors.
