The Step-by-Step Process of a Full Home Renovation with The O’Dell Group
What actually happens from your first call to The O’Dell Group to the day you move back in, and why understanding the process makes everything easier.
A full home renovation is one of the biggest investments you’ll make, and one of the most personal. You’re not just updating finishes or rearranging rooms. You’re reshaping the place where your family lives, gathers, and grows. That’s why the process matters as much as the result.
For homeowners across Fairfield County, from Westport to Weston, Easton to New Canaan, the question we hear most isn’t “what will it look like?” It’s “How does this actually work? How long will it take? And what should I expect along the way?”
Fair questions. The honest answer is, it depends on scope. A focused renovation that touches a few key rooms, say, a kitchen, mudroom, and powder bath, typically runs four to six months of active construction once design is locked. A larger full-home renovation, especially one that’s phased over time to follow the way a family actually lives in the house, can span a year or several. The shape of the project drives the timeline, not the other way around.
What stays constant is the process. When you work with a design-build firm like The O’Dell Group, every phase is mapped out before a single wall comes down. Here’s what that process looks like, step by step.
Phase 1: Discovery and Design
Timeline: 2–4 weeks
Every renovation at The O’Dell Group starts the same way: a conversation. Before we talk about materials or timelines, we want to understand how you live in your home and what isn’t working. Maybe the kitchen feels disconnected from the family room. Maybe you’ve outgrown the layout. Maybe you love the neighborhood but the house just doesn’t reflect who you are anymore.
During this phase, we conduct an initial site visit to assess the existing structure, talk through your goals and ‘non-negotiables’, and begin sketching the broad strokes of what’s possible. We don’t sell you on a scope here, it’s more about listening carefully so the design actually solves the right problems.
For Westport homeowners especially, this discovery phase often reveals opportunities that weren’t obvious at first, a way to open up sight lines, capture natural light, or reimagine an underused space. The best renovations come from this kind of thoughtful exploration.
Phase 2: Architectural Planning and Engineering
Timeline: 3–6 weeks
Once we’ve aligned on the vision, our in-house design team, led by Architect Mary O’Dell and Principal Designer Anita Avakian, will translate ideas into detailed outlines. Floor plans, elevations, cabinetry layouts, lighting plans, and, where necessary, structural engineering. It’s the phase where “I want the kitchen to feel bigger” becomes a specific, buildable design with dimensions, materials, and flow.
A current example is our project at #ODGxSturgesHighway in Westport. The homeowners wanted a renovation that touched the rooms a family actually lives in every day, kitchen, mudroom, and powder room, with a custom island as the centerpiece. Architectural planning produced a redesign with new millwork, a reimagined kitchen island, and a flow between mudroom, kitchen, and main living areas that suits how they actually move through the house. That level of detail in planning is what prevents costly changes during construction.
This is also when we coordinate with engineers and consultants as needed, structural, mechanical, low-voltage. If walls are moving or loads are shifting, we handle it now, not as a surprise later. And because our integrations team (Corbin, Fahad, and Victor) is in-house at ODG, smart-home wiring, lighting control, audio, and shading are designed into the project from the start, not bolted on after drywall.
Phase 3: Budget Alignment and Scope Lock
Timeline: 2–3 weeks
Let’s be honest: this is the phase that makes most homeowners nervous. But it shouldn’t be. Budget alignment is where transparency matters most, and it’s something we take seriously at The O’Dell Group.
Once the design is developed, we produce detailed pricing that breaks down every element, labor, materials, fixtures, contingencies. No vague allowances, no buried costs. We walk through the numbers together, line by line, so you can see exactly where the investment is going.
Sometimes this phase involves prioritization. Maybe the original scope needs to shift to stay within budget, or maybe there’s room to add something you’d considered a stretch. Either way, we work through it collaboratively, not as a negotiation, but as a conversation about what matters most to you.
We also lock the construction sequence during this phase. For full home renovations in Fairfield County, sequencing is critical, it determines how long you’ll be out of the house, which trades come when, and how the project flows from demo to completion.
Phase 4: Selections and Specifications
Timeline: 3–5 weeks
This is the part homeowners either love or dread: picking everything. Tile, countertops, hardware, plumbing fixtures, lighting, cabinetry finishes, paint colors, the list is long, and without guidance, decision fatigue sets in fast.
That’s why The O’Dell Group treats the selections process as a guided experience, not a scavenger hunt. We curate options based on the design direction, your aesthetic preferences, and the project budget. Instead of sending you to five showrooms with an open-ended list, we present focused choices that all work within the design framework.
We’ve found that homeowners in Westport and across Fairfield County want quality and cohesion, they don’t want to pick a faucet in isolation and hope it matches the tile they chose three weeks ago. By managing this process holistically, we make sure every material, finish, and fixture tells a consistent story throughout the home.
Typical selections include:
Countertop material and edge profiles (quartz, marble, quartzite)
Tile for bathrooms, mudrooms, and kitchen backsplash
Cabinet door style, finish, and hardware
Plumbing fixtures and fittings
Lighting fixtures and controls
Flooring, paint, and millwork details
Phase 5: Construction
Timeline: 3–9 months for most full-home projects; longer for phased, multi-room transformations
This is when the vision becomes physical. Construction on a full home renovation follows a well-defined sequence: demolition, structural work, framing, rough-in (plumbing, electrical, HVAC), insulation, drywall, and then the finish work that brings the design to life, cabinetry, tile, trim, paint, and fixtures.
A focused kitchen-plus-key-rooms renovation, like #ODGxSturgesHighway, runs roughly four to six months of active construction. Larger renovations, those involving additions, significant structural changes, or whole-house gut work, like #ODGcMelwoodLane extend longer. Our project management team provides weekly updates and maintains a detailed schedule so you always know where things stand.
One of our projects in Westport, #ODGxOverRockLane is a great example of how disciplined construction management keeps a complex, multi-room renovation on track. What began in January 2024 with painting, demolition, and millwork in the laundry and mudroom has expanded over time, through a full custom kitchen and pantry rebuild in fall 2024, into primary and kids’ closet systems through 2025, a meditation room buildout in late 2025, and a home gym this year. Three years in, the same crew is still on site, working through each new phase exactly the way the family wants to grow into their dream home. That kind of long-term partnership only works when the schedule, the trades, and the trust are all kept tight from day one.
Throughout construction, we manage permits, inspections, and subcontractor coordination so you don’t have to. Design-build means one team owns everything from blueprint to final coat of paint, no finger-pointing between architect, designer, and contractor.
Phase 6: Final Walkthrough and Handoff
Timeline: 1–2 weeks
The last phase is one of the most important, and one that separates a good renovation experience from a great one. Before you move back in, we conduct a comprehensive walkthrough of every room, every detail, every finish. This is the punch list: the final quality check where we identify anything that needs attention, adjustment, or correction.
At The O’Dell Group, we don’t rush this step. We created the design, we built it, and we stand behind it. The walkthrough isn’t a formality, it’s our opportunity to make sure every element meets the standard we set together at the beginning of the project.
We also provide a full orientation for any new systems: smart-home controls, HVAC, appliances, etc. So, you’re comfortable operating everything in your renovated home from day one, and our commitment doesn’t end at handoff. We follow up after you’ve settled in to make sure everything is performing the way it should. For the clients who want it, we offer ongoing house management from the same team that built the home.
Why Design-Build Simplifies Everything
Here’s what it comes down to: a full home renovation doesn’t have to feel overwhelming. When the process is clear, communicated well, and managed by a single team from start to finish, every phase builds naturally on the one before it. No gaps between architect and builder. No miscommunication between designer and contractor. No surprises.
That’s the design-build difference, and it’s why homeowners across Fairfield County, from a one-time kitchen-and-mudroom refresh in Westport to a multi-year, room-by-room transformation in Fairfield, choose The O’Dell Group for their most important renovation projects. We don’t just build beautiful homes; we make the process of getting there feel manageable, collaborative, and even enjoyable. Ready to start the conversation?
