Arcadia is a suburban, inland part of the San Gabriel Valley, so we plan an addition there around hard sun, gusty dry air and a rare downpour. Those conditions point at three places: the roof over the new room, the walls that take the afternoon sun and the ground around the new footings. Get those right, and a bedroom or family room stays pleasant to use all year and sheds water cleanly when rain arrives.

Holding back the heat

A new room loses or gains most of its heat through the ceiling, so the attic above it gets deep insulation and a vented space that lets hot air escape. A light colored roof covering reflects more sun than a dark one. Exterior walls framed with deeper studs leave room for thicker batts, and windows on the sunniest wall take low-e glass and, where it fits the look of the house, an overhang that shades them. The aim is a room the family can sleep in without running the air conditioning from dinner until bedtime.

Carrying water off the lot

An inland lot can go months without rain and then take a hard storm, and an addition has to handle both. Gutters along the new eaves feed downspouts that empty onto splash blocks or into pipes carrying water well past the foundation. The soil next to the new walls is graded to fall away from them, and the gap between the old and new footings is sealed. Where the new roof ties into the existing one, the flashing is stepped and lapped so the first heavy rain finds no opening.
