From Site Work to Certificate of Occupancy: The Custom Home Build Process Behind This St. Marlo Estate

Atlantic Construction & Remodeling · Duluth, GA · Custom Home Design & Build

A finished custom home looks effortless. The materials flow together, the proportions feel inevitable, the spaces work exactly as they should. What is not visible is the sequence of decisions, trade coordination, and quality checkpoints that produced that result — and that sequence is exactly what differentiates a design-build firm from a general contractor.

Building a custom home in St. Marlo Country Club at this level is not a straightforward construction project. It is a design and construction program that begins months before the first permit is submitted and continues through a comprehensive homeowner orientation after the certificate of occupancy is issued. Every phase has dependencies on every other phase — decisions made in the design phase determine what is possible in the framing phase, which determines what the finish phase can accomplish, which determines what the homeowner experiences every day for the next forty years.

The build process for this home followed the design-build model that Atlantic Construction & Remodeling uses on every custom project: a single team responsible for architectural design, structural engineering coordination, permit acquisition, construction management, and finish installation. No handoff between a design firm and a construction firm. No gap between what was drawn and what was built. One accountable team, from the first site visit to the final walkthrough.

Phase by Phase: How This St. Marlo Home Was Built

1
Site Analysis & Design Development (3–5 months) Full architectural drawing set developed through multiple revision cycles with homeowner input. Every ceiling height, window location, and floor plan decision made on paper before a permit is filed. HOA architectural review submission managed as part of this phase.
2
Permitting & Pre-Construction (1–3 months) Building permits submitted to Gwinnett County. All long-lead materials ordered during this phase — custom cabinetry, specialty windows, statement fixtures — so they arrive on schedule rather than becoming schedule risks after framing is complete.
3
Site Work & Foundation (4–8 weeks) Site clearing, grading, utility connections, and foundation work. Foundation inspections completed before framing begins. Drainage and site grading reviewed against the civil engineering plan to prevent drainage issues that surface years after move-in.
4
Framing & Rough-In Trades (3–5 months) Framing, rough-in plumbing, electrical, HVAC, and low-voltage wiring installed under a coordinated trade sequence managed by our project managers. Framing inspections completed at each phase before walls are closed.
5
Finish Phase (5–10 months) Drywall, paint, tile, cabinetry, millwork, stone, fixtures, and hardware installed in a sequenced finish schedule that minimizes trade interference. Weekly homeowner walkthroughs throughout. Punch list completion before certificate of occupancy is requested.

“The homes that finish on schedule and on budget are the ones that made every design decision before framing started. The homes that run late and over budget are the ones that left decisions for the field.”

Why Single-Firm Design-Build Outperforms Separated Teams

The most common source of cost overruns and schedule slippage in custom home construction is the coordination gap between the design team and the construction team. When an architect draws a home and a separate general contractor builds it, information is lost in the handoff. The contractor makes field decisions that were not contemplated by the architect. The architect’s design intent is not translated into the construction documents in ways the trades can execute. These gaps cost money and time on every project where they exist.

When the design team and the construction team are the same organization, the information gap does not exist. The people who drew the coffered ceiling understand exactly how it needs to be framed to achieve the proportions in the drawings. The people who specified the marble shower layout understand exactly where the plumbing rough-in needs to be to hit the niche location. Design intent is preserved through every phase of construction because the same team is responsible for all of it.

How long does a complete custom home build in St. Marlo take?

From initial design consultation to certificate of occupancy, a home at this finish level typically takes 18 to 26 months. Design and permitting account for 4 to 8 months. Construction runs 14 to 18 months from groundbreaking. Homes that complete fastest are homes where design was finished before framing started and where all long-lead materials were ordered during the permitting phase.

How often do homeowners receive project updates during construction?

We provide weekly progress photos and a monthly written schedule update throughout the construction phase. Homeowners have direct contact with the project manager and are welcome to visit the site at any point during construction. Major milestone walkthroughs — post-framing, post-rough-in, and pre-drywall — are scheduled as structured site visits with the project manager present.
