Tour a luxury waterfront home in Tampa Bay before drywall. These 6 build-stage details add lasting value — and cost far more to add after the walls close up.
In this guide, we’ll break down what each phase looks like, so you know exactly what to expect as your home comes together.
6 Things to Get Right Before Drywall in a Luxury Waterfront Home
When you tour a finished home, you see the floors, the glass, the kitchen. What you don't see are the decisions made weeks earlier — while the walls were still open — that quietly determine how the home lives, how much it's worth, and how much you'll spend "fixing" it later.
In our latest Behind the Build walkthrough, we stepped inside one of our Tampa Bay waterfront homes during the framing stage: block walls up, wiring run, plumbing in, nothing hidden yet. This is the most important window in the entire build, because almost everything below is easy and affordable to do now — and expensive, messy, or impossible to add once the drywall goes up.
Here are six details we get right before the walls close, and why each one matters.
1. Floor Outlets in the Main Living Area and Study
We place electrical outlets in the floor of the great room and study — right where furniture actually sits.
Why it matters: In a large open-plan living room, your sofa and chairs float in the middle of the space, far from any wall. A floor outlet means lamps, phone chargers, and a laptop in the study all plug in cleanly — no cords stretched across walkways, no rugs taped down over extension cords. It's the difference between a room that photographs beautifully and one that actually functions.
Costly after the fact: Adding a floor outlet later means cutting into finished flooring and the slab or subfloor, fishing new wire, and patching — often hundreds to a few thousand dollars per location, and you may never perfectly match the floor again. During construction, it's a minor line item.
2. Prewire for Sliders and Windows
We run low-voltage wiring to the large sliding doors and key windows before they're closed in.
Why it matters: Waterfront homes are built around the view, which means walls of glass. Prewiring lets you add motorized shades and automated window treatments on those big sliders and high windows — controlled by app, schedule, or voice — without battery packs or visible cords. It also future-proofs for security sensors and smart-home integration on the openings that matter most.
Costly after the fact: Retrofitting motorized treatments later usually means surface-mounted wiring, visible conduit, or battery units that need recharging — and on a 12-foot slider or a high transom window, that's both unsightly and pricey. Wiring during framing is hidden, clean, and cheap.
3. Additional Backing for Bathroom Accessories
We add solid wood blocking inside the walls wherever bathroom hardware will hang.
Why it matters: Towel bars, robe hooks, grab bars, floating vanities, and heavy framed mirrors all need something solid to anchor into. With backing already in the wall, every accessory mounts securely, exactly where you want it — including grab bars for safe aging-in-place, even if you don't need them yet.
Costly after the fact: Without backing, hardware either pulls out of the drywall over time or forces you to open up a finished, tiled wall to add support — which can mean re-tiling an entire section. Blocking added now costs almost nothing and saves a renovation later.
4. Uponor PEX Plumbing Lines
Our water lines are run with Uponor PEX plumbing rather than traditional rigid pipe.
Why it matters: Uponor PEX is flexible, corrosion-resistant, and run in continuous lengths with fewer joints — which means fewer potential leak points hidden inside your walls. It handles Florida's water well, resists the mineral buildup that narrows older pipes, and even delivers hot water a little faster. For a home you intend to keep for decades, it's a quieter, more reliable system behind the walls.
Costly after the fact: Re-piping a finished home is one of the most disruptive projects there is — opening walls and ceilings throughout the house, then repairing and repainting. Doing it right during construction avoids that entirely.
5. Bedrooms Wired for Ceiling Fans AND Can Lights
Every bedroom is wired for both a ceiling fan and recessed can lights — on separate switching.
Why it matters: In the Florida climate, a ceiling fan isn't optional — it keeps bedrooms comfortable and cuts cooling costs. But fans alone cast poor light. By wiring for fans and recessed lighting from the start, each bedroom gets proper ceiling support for a fan plus bright, even, controllable light, so the room works for sleeping, reading, or getting ready — no lamps required.
Costly after the fact: Adding recessed lights or a fan-rated ceiling box later means cutting into finished ceilings, running new wire through insulation, adding switches, and patching and repainting. Roughed in now, it's simply part of the electrical plan.
6. An Automatic Transfer Switch for the Generator
This is the one we tell every client not to skip: we install the automatic transfer switch for the whole-home generator during construction — not after.
Why it matters: In Tampa Bay, storm-season outages are a question of when, not if. An automatic transfer switch is the brain of a standby generator — it detects an outage and switches your home to generator power on its own, within seconds, with no cords and no one home required. Your AC, refrigeration, sump and pool equipment, and security keep running while the block goes dark.
Costly — and disruptive — after the fact: Integrating the transfer switch and generator circuits into the electrical system is dramatically simpler while the panel and walls are accessible. Adding it to a finished home often means reworking the main panel, running new conduit across finished surfaces, and significantly higher labor — sometimes thousands more than doing it during the build. Wiring for it now, even if the generator comes later, is the smart move.
Why This Stage Is Everything
None of these six details show up in a listing photo. But together they're what separates a true custom home from one that merely looks finished. They make the home more comfortable, more resilient, and more valuable — and every one of them is far cheaper and cleaner to do while the walls are open than to retrofit later.
That's exactly why we invite our clients behind the build. When you can see it before it's covered up, you know it was done right.

Frequently Asked Questions
What should I add to a custom home before the drywall goes up?
The highest-value pre-drywall upgrades are the ones that are costly to retrofit: floor outlets in open living areas, prewiring for motorized shades on large sliders and windows, in-wall backing for bathroom and accessibility hardware, quality PEX plumbing, ceiling-fan-and-recessed-light wiring in bedrooms, and an automatic transfer switch for a standby generator.
Why is an automatic transfer switch better installed during construction?
Because it ties directly into your main electrical panel and generator circuits. While the panel and walls are open, integration is straightforward and far less expensive. Adding it to a finished home can require panel rework, new conduit across finished surfaces, and much higher labor costs.
Is Uponor PEX plumbing better for a Florida home?
PEX is flexible, corrosion-resistant, and run with fewer joints, which means fewer hidden leak points and better resistance to mineral buildup — a durable, low-maintenance choice for a home you plan to keep for decades.
How much does it cost to add these features after a home is built?
It varies, but retrofits routinely cost several times the original install — and involve cutting into finished floors, walls, and ceilings, then patching and repainting. Done during construction, most are minor line items.
