A 420 sq ft bump-out and a new roof line
A rear addition on a new stem-wall foundation, tied into a 1971 hip roof with a framed valley and a re-detailed rear elevation.
How it went
The family needed one more bedroom and a larger gathering space, and they were not moving out. That constraint shaped the whole schedule: the tie-in wall stayed closed until the addition shell was weathertight, which meant the house had a full envelope at all times.
Zoning came first. The lot had already used most of its coverage on a 1990s patio, so the addition footprint was set by the impervious-surface limit before a single interior wall was drawn. The patio was reduced by 180 square feet to make room.
Roof geometry was the hardest part. A flat-roofed box would have been cheap and would have looked like a flat-roofed box. We framed a hip that reads as original from the street, which needed a crickets-and-valley detail and a full re-roof of the rear slope.
The family stayed through all fourteen months. The phasing plan on our living-through-it page came out of this project.

Fourteen months with two kids in the house. The zip walls and the temporary kitchen were the difference between manageable and unbearable.
