Project: 23 – 24 Henrietta, London

Principle Contractor: Knight Harwood

23-24 Henrietta Street is a Grade II Listed Victorian red brick building located close to the Piazza in the centre of Covent Garden. It was designed by Spencer Chadwick in 1885-86. This four storey office building has been redeveloped into a mixed use retail and residential units. The development contains five new luxury apartments.

Barwin were appointed to carry out external refurbishment and cleaning of the building facade. DOFF steam cleaning system was used to clean the brickwork at the front and rear façades to remove moss algae and general surface dirt. All the openings, airbricks and ventilators in the external walls were tape sealed to prevent water entry into the interior of the property or into any appliances connected to the exterior walls. The defective brickwork was cut out by means of hand tools and replaced with new brickwork to match existing. The defective pointing was removed, repointed and finished in style to match existing profile and colour.

Scope of works:

• DOFF system cleaning
• Removal and replacement of defective brickwork, brick matching
• Brickwork repointing
• Stone repairs using reconstituted mortar
