What to Expect When You Build a Custom Home with RDG: A Phase-by-Phase Guide
One of the most common things we hear from people considering their first custom home build is some version of this: I just don't really know what the process looks like.
That's completely fair. Building a custom home is one of the most significant things a family can do, and the process is genuinely complex. There are a lot of moving parts, a lot of decisions, and a timeline that spans more than a year from first conversation to final walkthrough.
We believe that the best antidote to anxiety in this process is information. So here's an honest, phase-by-phase look at what building with RDG actually involves — from the first consultation all the way to the day we hand you the keys.
Before construction begins: the foundation of a great build
A custom home build with RDG typically spans 16–18 months from start to finish. But the work that determines how well everything goes starts long before a single piece of ground is moved.
The first few months are devoted to pre-construction: surveying the land, soil testing, septic feasibility, architectural design, engineering, budgeting, and permit package preparation. This phase takes roughly one to three months, and it's where the relationship between our team and yours gets established. We'll have your first consultation, walk through design and planning together, and begin the personalized selections process that shapes everything about how your finished home will look and feel.
We use JobTread for estimating and project management, which means you'll have real visibility into your project throughout the entire build — not just updates when you ask for them.
Permitting and selections (months 3–4)
Once the design is locked in, we move into permitting and selections. Building permits are submitted, exterior selections are finalized, ARB submittals are completed (for communities like Jasper Highlands and River Gorge Ranch that have architectural review requirements), and long lead-time items — windows being the most common — are ordered early so they're on-site when they're needed.
This phase is often underestimated by first-time builders. Getting ahead of long lead items is one of the single most effective things we do to protect your timeline.
Site work and foundation (months 4–6)
This is when the land transforms. Erosion controls go in, the lot is cleared, footings are poured, and the foundation is set. For mountain lots in communities like Jasper Highlands or River Gorge Ranch, this phase requires particular expertise — the terrain demands it. Our team and our trusted site contractors know how to read these lots and build foundations that will perform for generations.
Framing and dry-in (months 6–8)
Framing is often the moment clients feel it for the first time. The house goes vertical. You're walking through rooms that exist as structure and space, standing where your kitchen will be, looking out the opening where a window will frame the view. It's one of the most exciting site visits of the whole process.
Once framing is complete, roofing, windows, exterior doors, and weather barrier follow — getting the structure closed in and protected from the elements.
Rough-ins (months 8–10)
Inside the walls, before anything is finished, everything that makes a home function gets installed: HVAC, plumbing, electrical, smart home wiring, security, EV charger prep, generator prep, fireplace, and insulation. This phase is invisible in the finished product, but it's where the long-term performance of your home is determined.
We don't cut corners here. The decisions made inside the walls are the ones nobody sees — and the ones a home remembers for fifty years.
Exterior and interior finishes (months 9–12)
This is when the vision starts becoming tangible. Exterior: siding, brick, stone, painting, gutters, porches, garage doors. Interior: drywall, doors, millwork, stairs, paint, flooring, tiled showers, cabinets, countertops, shelving, fireplace surrounds. This stretch of the build is the most visually dramatic — and the most detail-intensive.
It's also when all those selections you made early in the process come to life. There's something genuinely satisfying about watching a tile choice or a millwork profile show up in real life and look exactly the way you hoped.
Trim-out and landscaping (months 12–13)
Plumbing fixtures, electrical fixtures, hardware, appliances — these are the finishing touches that make a house feel like a home. Exterior concrete is poured, final grading is completed, and landscaping is installed. This is when a home goes from impressive to finished.
Final inspections and punch list (months 13–14)
Final electrical, plumbing, and mechanical inspections. Certificate of Occupancy. Deep clean. And the punch list — a thorough walkthrough where our team documents and addresses every detail before we hand over the keys. We take this seriously. The punch list isn't a formality; it's our final commitment to delivering what we promised.
And then — the final walkthrough
We walk the home with you together. Every system, every finish, every detail. We explain how everything works, answer every question, and make sure you feel completely at home in your home. Your one-year warranty begins at closing, and our team remains available and reachable well beyond it.
A few things worth knowing
RDG is licensed in both Tennessee and Alabama. We build on your lot. We welcome clients who bring their own plans. We offer full design-build services. And we don't have a formal change order process — if something changes mid-build, you communicate it and our team delivers. We believe building a home should feel like a partnership, not a contract negotiation.
Investment ranges from $250 to $300 per square foot for a custom home, $300–$400 for premium custom, and $400+ for luxury estate builds. We're transparent about costs from day one — because surprises in a budget are exactly the kind of thing we're working to prevent.
If you're beginning to think about what building could look like, we'd love to walk you through it in person.
