The air vents, which are handmade using a mould, are going in to give both ventilation and additional light.
The vents also help to keep down the costs
The steps, paths and floors all made from the local stone, galana, are also being laid.

Francis update
Francis, 13, who is being treated for a serious bone infection, osteomeylitis, was in Malindi yesterday at Tawfiq Hospital, we will bring you an update with video tomorrow - internet connection permitting.
We have a special JustGiving page where you can contribute towards the cost of his treatment.
There is no National Health Service in Kenya and we will have to fund all the care he needs.
