Can my loft be converted?
Almost all lofts can be converted, however, it does depend on the height of the apex (top of part of roof). A required minimum head height of 2.500 metres from ceiling to the apex is needed for a modern truss roof, and 2.400 metres for a traditional cut and pitch style roof. If your roof is not high enough then a dropped landing to the top staircase or lowering the ceilings to the 1st floor may be required. If your property is detached then raising the roof should be considered. Further information is available on our Types of Roof page.
How long will my conversion take?
It usually takes 5 to 9 weeks to complete depending on the size of the project. An approximate time will be given when our surveyor carries out your free feasibility survey. When we have designed your loft conversion we will provide start and completion dates with the quotation.
