Thomann-Hanry® revitalise Clarence Terrace.

Clarence Terrace, an architectural gem nestled in the picturesque surroundings of Regent’s Park, recently underwent a transformative makeover courtesy of Thomann-Hanry®, specialists in the restoration and rejuvenation of historic buildings.

One of Nash’s gems

Overlooking the verdant expanse of Regent’s Park in Marylebone, Clarence Terrace stands as a testament to Georgian grandeur, boasting a grade I Listed status and a rich heritage dating back to its construction in 1823.

The terrace, designed by the eminent architect Decimus Burton under the supervision of John Nash, forms part of Nash’s Regent’s Park Crown Estate development and was constructed by James Burton. Despite its illustrious past, Clarence Terrace required external redecoration to maintain its architectural integrity and aesthetic appeal.

Our works as part of Regent’s Park quinquennial redecoration programme

Thomann-Hanry®’s involvement in the project encompassed a comprehensive redecoration of the front and rear elevations of 1-43 Clarence Terrace, including all previously painted masonry, windows — about 150 of them — and frames, doors, and metalwork.

The redecoration works commenced with a thorough assessment of the building’s exterior, followed by a tap-test survey which was conducted to ensure the substrate’s soundness before proceeding with the removal of loose and defective render. The team then applied two coats of Dulux Weathershield in the estate colour — Regent’s Park Cream — to achieve a flawless and durable finish.

For doors, windows, window frames, and sills, surfaces were prepared with minor filling and repairs before the application of spot primer, undercoat, and finish coats. Ground and first-floor railings, along with downpipes, underwent a similar process, including rust removal and the application of a Metalshield paint system to protect against corrosion. To adhere to safety regulations concerning lead paint, a common feature in older buildings like Clarence Terrace, measures outlined in the Control of Lead at Work Regulations 2002 were implemented to prioritise the safety of our employees, residents, and visitors during the redecoration process.

Maximising efficient, minimising disruption

A distinctive aspect of the project was our modus operandi, employing hydraulic Mobile Elevated Work Platforms, thereby eliminating the need for costly scaffolding, offering unparalleled speed, convenience, and security. One advantage of utilising our platforms is their mobility, allowing us to relocate them to the side of the building when not in operation. As a result, there is minimal visual impact on the building during evenings and weekends, ensuring uninterrupted enjoyment for tenants throughout the project duration.

The project spanned over 20 weeks, and involved a team of skilled painters and decorators working diligently to breathe new life into Clarence Terrace. This successful redecoration project stands as a testament to our expertise in heritage restoration and our dedication to preserving London’s architectural legacy.
