Building Consultancy
SHW’s Building Consultancy Team successfully delivered a programme of external repairs, maintenance, and redecoration works at 3 Cadogan Square, Chelsea, London, on behalf of Cadogan Estates Ltd.


Project Overview
Appointed as both Contract Administrator and Project Manager, SHW oversaw the delivery of works to this fully occupied six-storey residential building, located within a prominent Chelsea conservation area.
The project was procured under a JCT Minor Works Building Contract, with Rama Property Refurbishment Ltd. acting as Principal Contractor. The works were completed within a 14–16 week programme, with a contract value of £145,026.10 plus VAT.
Project Challenges
Delivering external refurbishment works to a live residential building in a high-profile conservation area presented a number of challenges:
-
Maintaining resident comfort and safety throughout the works
-
Minimising disruption in a fully occupied property
-
Adhering to strict requirements associated with a conservation area location
-
Ensuring consistent quality across a varied and detailed scope of works
SHW addressed these challenges through proactive planning, clear communication, and careful on-site management.
Scope of Works
The project encompassed a comprehensive package of works across the building’s external envelope, including:
-
Roof works: Replacement of defective slates, application of liquid waterproofing to box gutters, leadwork treatment, and asphalt repairs
-
Façade repairs: Repointing, specialist masonry cleaning using a DOFF nebulous water system, and detailed stonework and cornice repairs
-
Joinery upgrades: Overhaul of timber windows and doors, including resin repairs, putty replacement, and sash easing
-
Drainage and rainwater goods: Cleaning, sealing, and a full CCTV drainage inspection
-
External redecoration: Application of Dulux Trade Weathershield systems to all timber, metal, and masonry surfaces
A pilot window sample was prepared and approved by the Contract Administrator prior to full rollout, ensuring quality standards and finishes were clearly established from the outset.
Delivery Approach
SHW maintained a hands-on role throughout the project, ensuring:
-
Close coordination between contractor, client, and residents
-
Strict quality control procedures, including staged inspections
-
Effective programme management to maintain timelines
-
Sensitivity to the building’s architectural and heritage context
Particular emphasis was placed on maintaining consistency in workmanship and finishes across all elements of the façade.

The project was successfully completed within programme, achieving an exceptionally high standard of workmanship throughout.
Key outcomes included:
-
A refreshed and well-maintained external appearance
-
Enhanced durability and long-term protection of the building fabric
-
Minimal disruption to residents during a complex, live project
-
High client satisfaction, supported by SHW’s proactive and collaborative management approach
Conclusion
