Sunnyvale Bungalow Renovation

These clients requested an extention to their existing 2-bedroom, 1 bathroom home and a repair of their foundation, which was cracked and rotating. Despite our best efforts to save much of the original structure, the only part we could salvage was the garage slab and footings.  The rest of the house replaced the existing footprint, with a small expansion to the rear yard.  The size of the house was increased from 1,100 sf to 1,500 sf, and a careful reconfiguration allowed the addition of another bedroom and small bathroom. New framing allowed us to vault the main living space to make the house feel expansive and the addition of a large, glass sliding door opened up the family room to a big new deck at the rear of the property.  At 1.43 ACH n50, this project did not quite meet Passive House air-tightness levels for a renovation, but the project was modelled in the PHPP and is performing in line with the predicted model.  A full solar array has been added to the rear, south-facing roof slope and is expected to produce sufficient energy to cover both house and vehicle-charging needs.
