¿Broma para el primero de abril?

Sadly this isn't a joke for April Fool's day. The construction on the road 30 feet below us is now level and exceeding the height of our single storey house. Work is continuing apace complete with shouting and loud music, and some comedian has erected a Spanish flag on top. It's at least twice the height of the houses either side on the same road. The mesh fence at the bottom is the boundary of our garden. Also the view from my bedroom window in the morning is just a concrete wall. The songbirds which used to announce the dawn have all disappeared.
