We are structural engineers for this residential project in west London. It involves a deep basement under the whole footprint of an existing townhouse, and extensive remodelling using steelwork for the above ground floors. The basement was constructed in two-lift segments, underpinning the party walls on each side. Temporary steelwork was inserted under the ground floor to allow work on the superstructure to proceed while excavations continued below.
Watch this space for more details after completion.
