This project allowed us to construct a janitorial house on the roof of a hotel in Eastleigh, Sixth Street, Nairobi. The challenge of this project was to operate the construction site without interfering with the busy hotel operations. That means no dirt/dust and no noise during construction. After a good 7 days, the janitor's house could be occupied.
We also construct perimeter walls as illustrated below by this wall that we built in Mlolongo, Machakos County.
