Secretariat Dr
Residence

A master bedroom and bath addition in Tempe — the back of the home opened up, a new suite built off the existing structure, and the roofline carried across so it reads as one house.

01 — The Project

More home, same house.

A ground-up master suite — bedroom and full bath — added onto the back of an existing Tempe home, engineered to disappear into the original architecture.

Additions live or die at the seam. Phillips Group cut into the original block wall, poured a new slab against the existing foundation, and framed the suite so the new gable picks up the exact pitch of the original roof. Fresh sheathing and matching shingles run across old and new — so when the finishes go on, there is no "old house" and "new house." Just one home, with the master suite it always needed.

02 — The Process

Block wall to new suite.

One team took the home from first drawing through demolition, foundation, framing, and roof tie-in.

Design

Design & Engineering

The suite was planned off the rear of the home, with structural engineering for the block-to-frame tie-in and a gable matched to the original roof.

Approvals

Permits

Permitting handled in-house, so demolition could start on schedule and inspections tracked with the build.

Build

Demolition & Shell

The block wall opened up, a new slab poured against the original foundation, and the suite framed and sheathed by our own crews.

Tie-In

Roofline & Envelope

Roof sheathing and shingles carried across both structures, windows set and wrapped — sealed in and ready for finishes.

Thinking about adding on?

Master suites, second stories, and room additions across California and Arizona — designed, permitted, and built by one team, with the seams engineered away.
