A loft conversion is usually the cheapest square metre you will ever add, because the roof, walls and foundations already exist. Whether it works comes down to head height, roof pitch and where a compliant staircase can land.
We survey the roof space first and tell you honestly whether it converts. Where the head height is marginal, the options are usually a dormer, a hip-to-gable extension, or lowering the ceilings below — each with different cost and planning consequences.
Escape routes, fire separation and stair geometry are what building control will look at hardest. Designing those in from the start avoids expensive changes later.
