This project involves extensive structural and architectural work on a classic San Francisco painted lady single-family Victorian home.  As is often the case, the front and back walls of this building consist mostly of windows and doors, so initially the building had very little lateral load resisting capacity.   Our challenge was to strengthen the building while minimizing disruption of the elaborate finishes.  We were able to add plywood shear walls on the interior short direction walls, but the very limited wall space on the front and rear lines called for the use of steel frames.  To keep drift to within code limits we bolted  the frames to new concrete walls in the basement.
