Arundel House

London, WC2R 3DX – June 2025

Styles Façade Solutions (formerly Thomann-Hanry®) was initially appointed to undertake a detailed commercial building façade survey, identifying key areas of concern and providing a fully illustrated report to support ongoing maintenance and asset management. Following the survey’s recommendations, our expert facade cleaning services delivered a clear strategy for preserving the building’s appearance, condition, and long-term structural integrity.

Following the assessment, our specialist façade cleaning services were commissioned to restore the red-brick and Bath stone exterior. Using the Façade Gommage cleaning process, we completed the commercial façade cleaning project in just six days without intrusive scaffolding. This low-pressure, water-free, chemical-free process safely removed years of dirt and pollution while protecting delicate Tudor-style carvings and masonry details.

Our external façade cleaning approach revealed the building’s original Victorian character, from basement level to the attic quarters, without risking damage to historic materials. To provide lasting protection, we applied AquaFEND® F, a specialist treatment that reduces surface soiling, inhibits algae and moss growth, and helps keep the façade cleaner for longer.

Façade Cleaning Façade Surveys

Styles Façade Solutions (formerly Thomann-Hanry®) was commissioned to clean the full façade of Arundel House, London using the scaffold-free Façade Gommage cleaning process.

A CLEAN STUDY OF ARUNDEL HOUSE

Originally on the site of Bath Inn, which was built in the Middle Ages and originally home to the Bishops of Bath & Wells, the first Arundel House was purchased in 1550 for just £40 by Henry Fitz Alan, 12th Earl of Arundel.

During the late 19th Century, the current structure was built in the popular Tudor Revival style as a reaction to the highly ornate Victorian Gothic trends of the era. Today, this striking building serves as a conference centre and the global headquarters for the International Institute for Strategic Studies (IISS), a leading defence and security think-tank.

Styles Façade Solutions® brings expert care to heritage brickwork with its façade gommage cleaning process, gently lifting grime from intricate gothic stone dressings and red brick without abrasive damage. This precise, dust-controlled technique preserves historic character while revealing the true colour and craftsmanship beneath decades of pollution.

FAÇADE INSPECTION AND SURVEY

Styles Façade Solutions (formerly Thomann-Hanry®) was first instructed to carry out a detailed façade survey. Our objective was to better understand the key areas of concern to inform the ongoing façade maintenance and management programmes. We provided the client with a fully detailed and illustrated report offering a clear roadmap for preserving the building’s structural integrity.

The red-brick and Bath stone façade had not been cleaned for many years and needed a thorough yet sensitive clean. Using the Façade Gommage cleaning process, the project was completed in just six days and all without the need for intrusive, expensive and unsightly scaffolding. This speed and lack of disruption are why multi-award-winning Styles Façade Solutions has gained the reputation of being the trusted expert for high-profile historic and commercial properties.

After — Styles Façade Solutions (formerly Thomann-Hanry®) transformed the appearance of Arundel House, London, using the specialist Façade Gommage cleaning process. The Portland stone dressings are dramatically brightened to a crisp cream, beautifully contrasting with the rich red brickwork and revealing the full splendour of the Victorian Gothic detailing.

SENSITIVE CLEANING: REVEALING THE DETAIL

Our low-pressure, water-free, chemical-free, aggregate-free expert facade cleaning process offers both historical and commercial buildings a way to revive and refresh a building’s façade without the worry of structural or material damage. The gentle cleaning process was the perfect solution for cleaning Arundel House’s flat surfaces and the intricate Tudor-style carving details without risking damage to the different substrate types.

From the basement to the former servants’ quarters in the attic, our team meticulously peeled back the years to reveal the original façade as envisioned by its Victorian architects. To ensure the long-term protection of the building’s façade, we applied AquaFEND® F to the masonry. This specialist treatment reduces surface soiling and inhibits biofilm growth (algae and moss), keeping the building cleaner for longer.

“We are always privileged to restore and renew historically important buildings like Arundel House. The high-quality results we delivered during this project are a testament to the meticulous service Styles Façade Solutions has become known for. We will always strive to provide a level of care and efficiency that exceeds our clients’ expectations.”
