A newly designed Central London apartment underwent full redecoration, both internally and externally throughout. With the combination of bespoke finishes, heritage restoration and premium materials, every detail was carefully crafted to enhance the property's refined elegance. The results seamlessly integrating classic architecture with modern sophistication.

A high-specification apartment in Knightsbridge suffered water damage affecting three primary areas: the main reception, media room and an additional living space. The scope of works involved comprehensive protection measures, restoration of timber flooring, ceiling and wall decorations, electrical testing and final reinstatement of furnishings. The objective was to restore the apartment to its original high-end condition while minimising disruption to the client.

To prevent damage and contain airborne dust, extensive protection measures were implemented: 

• Cordec corrugated plastic sheeting, polythene sheeting, carpet roll and stroll and dust sheets were used to safeguard all walls  and floors. 
• A protected walkway was installed from the entrance to the working areas. 
• Adjacent areas were screened off using polythene sheeting to restrict dust transfer. 
• Curtains, pelmets and furniture were carefully removed, wrapped in polythene and stored safely. 
• Photographic records were taken to ensure the precise repositioning of items post-restoration.

The timber flooring, covering approximately 40sqm across the main reception and media room, was refinished due to water exposure. Close monitoring of the wood condition was conducted to assess potential shrinkage or cupping of boards. The floors underwent a professional repolishing process to restore their original high-gloss appearance in keeping with the apartment’s luxury aesthetic.

Ceilings and affected walls required redecoration to rectify water damage and restore a pristine finish. 

• All ceiling fixtures, including speakers and down lights, were lowered and reinstated after decoration. 
• Hairline cracks were raked out and repaired using professional taped joint systems. 
• Stain-block treatment was applied to prevent discoloration in water-damaged areas. 
• Ceilings and walls were repainted in two coats of premium matt emulsion, matched to the original colour and specification.

To maintain the apartment’s high-spec lighting system, electrical testing and replacements were carried out. 

• Two new ceiling speakers were installed in the media room  
• A full NICEIC was conducted on the lighting circuits and down lights in all affected rooms. 
• Any down lights displaying corrosion were replaced with new units to ensure reliability and performance.

Post-restoration, a structured clean-up and reinstatement process ensured the apartment was returned to its original condition. 

• All protection materials were removed and disposed of responsibly using a licensed waste disposal service. 
• Curtains, pelmets, furniture and personal effects, including artworks, were reinstalled to their original positions based  on photographic records.

Following all works, a professional deep clean of all affected areas was conducted to remove dust, debris and any residual contaminants,  ensuring a flawless finish in keeping with the apartment’s luxury standards.

The restoration was successfully completed with minimal disruption to the client, ensuring a seamless return to the apartment’s original  high-spec condition. The careful planning, premium materials and professional execution upheld the exclusivity and prestige expected  in a Knightsbridge residence.

"I have worked with Simon and his team at JRSL on numerous high-end building projects over the years, and the results have always exceeded expectations. Their attention to detail and quality of finish are truly exceptional—far beyond the industry standard. They pursue perfection, achieving levels of craftsmanship that many wouldn’t even consider possible. 

If you provide JRSL with the time and space they need, they will deliver the finest finish available on the market. However, what truly sets Simon apart is his integrity. He is a man of his word—someone you can trust implicitly. This level of trust cannot be assigned a price, but once you experience it, you will never want to undertake another project without it"
