Noise is the first thing a new Altadena bedroom has to solve, with sleepers on one side of a wall and a television or dishwasher on the other. We place the door swing, the closet and the bathroom so the room backs onto quiet space, and keep it clear of the busiest part of the living area. Light, storage and an outlet by the bed come next, once the sleeping arrangement works.

County review and fire hazard maps

Altadena is unincorporated, which sends the plans to Los Angeles County for review. Mapped fire hazard zones cover portions of Altadena, so a lot inside one may need ember-resistant vents, roofing and glazing, drawn into the set from the start because adding them after a correction notice means redrawing sheets. Clearances to the lot edges, built area and the height cap get tested against county zoning before the first sketch, and each reviewer comment is answered in writing until the permit is ready.

Keeping the new wing comfortable

A new wing needs its own plan for heating and cooling. The existing system may stretch to cover it, or the room may call for a ductless unit or a larger furnace and coil, and we run the load calculation during design. Insulation in the new walls and roof, windows rated for the sun they face and a roof overhang above the glass all cut the load. A ceiling fan rough-in and a few spare outlets are easy to add while the walls are open and awkward to add afterward.
