When considering having a loft conversion to your home, the first thing to establish is if the existing height within your roof is tall enough. The general rule of thumb measurement is 2.2m from the top of the existing joists to the underside of the ridge (the point in the middle).
If your roof is lower than 2.2m it generally means a legal loft conversion is not possible as the finished height within the loft would be under 2m. However, as an alternative, to create the necessary height required to achieve a liveable loft space, your existing ceilings to your upstairs rooms can be removed and the new structural floor can be constructed at a lower level than the original ceiling. This operation, although slightly eats into the original height of your upstairs rooms, creates the height required for a loft room. The downside to this process is that you will have to vacate your home while this element of the work is carried out. The duration of this operation is normally 2 weeks and comes at the very beginning of the build.
