Heritage Refurbishment of Grade I Listed Terrace

External refurbishment works to Grade I listed London terrace carried out by Armour Hart Group
  • Work: External Repairs and Decorations

  • Duration: 24 weeks

  • Value: c. £920k

Description

We were proud to deliver the external refurbishment to one of London’s most iconic Grade I listed Georgian terraces. Built in the late 18th century by architect Michael Searles, the crescent is regarded as a masterpiece of classical design and is recognised as one of the finest surviving examples of its kind in the country.

The terrace is home to leaseholder blocks and has long been celebrated for its unique architectural character and historic value, making this refurbishment both a privilege and a responsibility. The works demanded care, coordination, and craftsmanship at every stage.

Our scope included renewal and repair of large bespoke curved timber and traditional sash windows, full re-roofing of slate-tiled pitches, application of liquid waterproofing systems to parapet gutters, and renewal of all lead flashings; masonry repairs from intricate stonework restoration to lime mortar repointing, followed by careful redecoration using heritage-approved paints.

Once scaffolding was erected, it became clear the external fabric required more intervention than initially scoped, particularly the timber windows. We responded flexibly, working closely with the client team to manage the programme and costs transparently. Resident liaison was central to the project. Our RLOs worked hand-in-hand with households throughout, providing clear schedules, responding to individual needs, and minimising disruption wherever possible.

This was particularly important given the programme duration and the scale of scaffold. This project demonstrates our capability in complex heritage refurbishment and reflects our values: combining technical skill and historic sensitivity with integrity, transparency, and respect for the communities we serve.
