Rear extension of row house over 3 levels

This is an extension to a row house on several floors. The biggest challenges were

1) having to work without a work machine. No crane could get at the rear of the building.

2) fixing two metal beams throughout the length of the house to assire stability

3) Very deep foundations to meet the requirements of the different technical experts.
