Some teachers who live in the Mussafah section of Abu Dhabi had their car garage collapse recently:
The two reasons suggested by The National (U.A.E. newspaper) so far include: "Building in the UAE is often complicated due to the sandy soil, according to engineers" and "The weight of the garden is an equally important consideration. Mr Saadi stressed gardens 'must be included in the design stage' as soil was 'very heavy'."
Thankfully, we haven't heard of anyone being harmed, and insurance should cover the damaged cars.
