Increasing risk? ... time for a call to Kevin
Compared to a traditionally built houses we have made great progress over the last 4+ months but over the last couple of weeks we have experienced a few hic-cups.  The most testing issue (in true Grand Designs style 🙂) is the installation of the windows. The bespoke, triple-glazed windows for our rear glazed gable end are lovely, and just what we wanted, but are very heavy.  Even manually off-loading the glass takes a five man team. The next step is to find a way of lifting the glass into position 3+m above the ground (NB the frames are already).  The most likely solution is to use a spider crane - unfortunately this wasn't budgeted for, nor were the costs of operators (apparently you need three people to guard against the risk of something going wrong).
