The Wandsworth basement project, completed in 2018, showcases O’Sullivan Civil Engineering’s capability to create valuable additional living space through expert underpinning and basement construction in residential South West London properties. This carefully executed project transformed an existing private house by adding substantial basement accommodation beneath.
Our comprehensive scope encompassed systematic underpinning works protecting the property’s structural integrity throughout construction, precision installation of permanent structural steelwork providing essential support, construction of a light well enhancing basement livability with natural daylight, and professional metal deck flooring installation completing the structural floor system. This project demonstrates our expertise delivering residential basement extensions that add significant value while maintaining existing property safety.
