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.

Project: Loxford House, Higbury Park, London

Client: Mount Anvil

Duration: 4 Weeks

Loxford House, a mansion built in the mid-19th century, was once the residence of the Dent family, renowned as glove makers. It is an excellent example of Regency style architecture with an elegant white stuccoed facade.

Loxford House was recently restored to its original glory and converted into luxury refurbished homes. The focal point of Loxford House is a delightful clock tower.

Barwin cleaned and then overcoated the original stonework which was defective and aesthetically unpleasant, using a reconstituted stone mortar. This was skilfully applied and finished by hand to replicate the detail and profile of the original stone.

Bentley Priory includes a Grade II listed 18th Century Mansion House, adjoining historic buildings and Italian Gardens. Originally built in 1766, Bentley Priory was extended in 1788 by Sir John Soane for John Hamilton, 1st Marquess of Abercorn. The priory was the final home of the Dowager Queen Adelaide, queen consort of William IV, before her death there in 1849. It subsequently served as a hotel and girls’ school before being acquired by the Royal Air Force in 1926. Bentley Priory was a working RAF base until 2008. The site has been developed by City & Country into the new homes and museum.
