What Type of Loft Conversion Is Best for a Semi-Detached House?
The best type of loft conversion for a semi-detached house in London is typically a hip to gable conversion combined with a rear dormer. This combination maximises the available space by extending the sloped hip roof into a flat vertical wall on one side, while a dormer at the rear creates additional headroom and floor area.
