Building Consultancy, Residential, SHW News
SHW’s London Building Consultancy Department was engaged as Contract Administrator and Principal Designer to manage the refurbishment of a period residential property in South Lambeth, London.
Project Overview
The building, consisting of multiple flats, required significant external fabric repairs due to ongoing weathering, deteriorated render, and general surface wear. Additionally, concerns regarding the integrity of the main roof called for a comprehensive strategy focused on effective restoration and long-term preservation.
Key Challenges
-
Deficiencies in render and cracking were noted across the façade and require detailed assessment.
-
Specific risks of water ingress were identified at the main roof, which could compromise the integrity of the structure.
-
Preserving the character and intricate details of the traditional period elevation is essential while enhancing the performance of the building envelope.
Project Delivery
SHW managed and oversaw a comprehensive program of external refurbishment works comprising key elements as outlined below:
-
Liquid Waterproofing to Main Roof
-
A high-performance, liquid-applied waterproofing system was installed on the main roof, providing a seamless and robust protective layer. This approach ensured that all substrates and junctions were thoroughly encapsulated, enhancing long-term durability and reducing the risk of future water ingress.

Render Repairs
-
Damaged sections of render were removed, stabilised, and repaired with breathable, compatible mortars. Special attention was paid to restoring original mouldings and architectural profiles, thereby preserving the building’s historic character and visual integrity.

-
External Redecoration
-
Following thorough surface preparation, façades were redecorated with premium masonry coatings to improve both aesthetic value and weather resistance. Architectural features including balustrades and window surrounds were carefully restored, resulting in a consistent and refined appearance throughout the property.
