Kitchen Extension with Retaining Wall

We have had architect designs to extend our kitchen, where the back wall is a retainer wall for a tiered garden. We would like to move an existing buttress to allow for a better flow of the kitchen, as well as new steel work to allow for the extension.

Ideal Skills and Experience:
- Experience in building with tiered gardens
- Knowledge of retaining wall construction
