Before and after: A typical hip to gable conversion by Oxford Loft Conversion What is a Hip to Gable Loft Conversion? A hip to gable loft conversion involves changing the sloping side of your roof (the hip) into a vertical wall (the gable). This structural modification extends the existing ridge line to meet the new gable end, effectively squaring off your loft space and creating significantly more usable floor area with full head height. This type of conversion is particularly suitable for semi-detached, end-of-terrace houses and detached properties that have a hipped roof. By replacing the sloping roof with a vertical wall, you gain valuable additional space that would otherwise be lost to the roof’s slope.
