Building a Custom Home? 12 Things You Need to Decide Before Drywall

You’ve spent months designing your dream home. The foundation is poured. Framing is complete. Electrical

and plumbing rough-ins are underway. Everything is finally starting to feel real. But there’s one critical phase

of construction that homeowners should never overlook. The period before insulation and drywall is one of

your last opportunities to make relatively inexpensive changes to what’s inside your walls.

During Episode 18 of the Dallas Builders Club Podcast, Dennis from Builder Brigade joined us to discuss the

importance of homeowner education and construction planning. One recurring theme was that homeowners

often focus on finishes while overlooking the features that make a home truly functional. Here are 12 decisions

you should carefully review before drywall begins.

1. Electrical Outlet Locations

Walk through your home and imagine how every room will be furnished. Where will the nightstands go?

Where will you charge your phone? Do you need floor outlets in a large living room? Consider additional

outlets in closets, pantry areas, garages, outdoor living spaces, and behind televisions. An outlet that costs

relatively little during rough-in can become a frustrating retrofit after move-in.

2. Light Switch Placement

Light switches should follow the way people naturally move through a home. Walk through every doorway and

think about how you’ll enter and exit each room. Consider three-way switching in hallways, staircases, large

bedrooms, and open-concept living spaces. Don’t wait until the drywall is installed to discover a switch is on

the wrong side of the room.

3. Low-Voltage Wiring and Technology

Today’s luxury homes often require extensive low-voltage planning. Consider networking, security cameras,

Wi-Fi access points, automated shades, televisions, speakers, and smart home controls. Even if you don’t

plan to install every feature immediately, rough-in provisions can make future upgrades easier. Technology

changes quickly. Accessible pathways and thoughtful infrastructure provide flexibility.

DALLAS BUILDERS CLUB | EPISODE 18 14. Soundproofing Between Rooms

Soundproofing is one of the most underrated custom home upgrades. Interior wall insulation can help reduce

sound transmission between bedrooms, bathrooms, home offices, and entertainment areas. During the

podcast, we discussed using mineral wool insulation in a media room and the noticeable improvement in

acoustic comfort. Also consider sound transmission from plumbing stacks, mechanical equipment, and

upstairs bathrooms.

5. Additional Storage Opportunities

Walk through the framing and look for unused spaces. Could an oversized wall cavity accommodate recessed

shelving? Could a hallway include a linen cabinet? Could an otherwise unused space become additional

storage? One of our clients identified opportunities for built-in shelving during construction that weren’t

originally part of the design. These are exactly the kinds of improvements that become obvious when you

physically walk the home.

6. Plumbing Fixture Placement

Confirm the location of every sink, shower fixture, tub filler, and hose bib. For showers, consider niche

placement, handheld shower locations, and whether the controls can be reached conveniently. Outside, think

about water access near patios, pools, gardens, and outdoor kitchens. Dennis shared how homeowners often

realize too late that they should have installed another hose bib.

7. Kitchen Functionality

Beautiful kitchens should also be practical. Think about appliance placement, cabinet organization, countertop

outlets, undercabinet lighting, and pantry functionality. Where will you store small appliances? Would

additional outlets inside a pantry improve convenience? Consider how you cook and entertain rather than

designing solely around photographs.

8. Backup Generator Infrastructure

Texas homeowners understand the importance of preparing for power outages. During our conversation,

Dennis identified generator infrastructure as one of the upgrades he’d prioritize with additional budget. Even if

a whole-home generator isn’t part of your immediate plan, ask your electrician about the feasibility and cost of

preparing for future backup power. Any generator connection must be properly designed and installed with

appropriate transfer equipment and electrical protection.

9. HVAC Comfort and Access

Before drywall, review the locations of supply registers, return-air pathways, thermostats, and equipment

access points. Think about furniture placement and whether large windows could affect comfort. Ask your

builder and HVAC contractor how the system is designed to serve different areas of the house. Proper design

matters more than simply choosing expensive equipment.

DALLAS BUILDERS CLUB | EPISODE 18 210. Blocking for Future Fixtures

Wall-mounted televisions, floating vanities, heavy mirrors, handrails, and certain cabinetry installations may

benefit from additional blocking. Identify these locations while framing is exposed. Adding support during

construction is usually easier than opening finished walls later.

11. Waterproofing and Window Installation Details

One of the most technical discussions in Episode 18 involved window flashing and moisture management. We

shared a real construction example where a homeowner questioned why certain window areas weren’t

sealed. After consulting the product representatives, it was confirmed that the specific window installation

needed to preserve its designed drainage path. Sealing the wrong location could have trapped moisture and

affected the manufacturer’s warranty. The lesson isn’t that homeowners should direct waterproofing

installations themselves. It’s that they should ask questions and ensure installation details follow the approved

design and manufacturer requirements.

12. Photograph Everything Behind the Walls

Before insulation and drywall, document the construction. Take clear photographs of walls, ceilings, electrical

runs, plumbing locations, blocking, and other concealed features, with your builder’s approval and appropriate

site safety precautions. These photographs can become extremely useful when mounting televisions, making

renovations, or locating concealed components years later. Dennis strongly recommends documenting what’s

behind the walls because it’s an opportunity homeowners won’t have once construction is complete.

Your Pre-Drywall Walkthrough Matters

Before drywall begins, schedule a dedicated walkthrough with your builder. Bring your floor plans, electrical

drawings, selections, and a list of questions. Don’t rush through the house. Imagine an ordinary day living

there – from waking up and making coffee to entertaining guests and getting ready for bed. The goal isn’t to

find fault with your builder. It’s to identify opportunities while changes are still practical.
