West London’s outstanding property values — from riverside Richmond and Barnes to fashionable Chiswick and Fulham — make loft conversion one of the most rewarding investments available to homeowners in the area.
West London is characterised by diversity of property type and exceptional values. Richmond, Barnes, Kew and Twickenham have predominantly Edwardian and Victorian housing stock at some of London’s highest price points. Chiswick and Fulham occupy the sweet spot between outstanding housing stock and outstanding demand. Ealing, Acton and Hounslow offer strong ROI on 1930s semi-detached properties.
