When building or renovating a home, most people assume they know the right sequence for every step. But the truth is, some construction choices aren't as obvious as they seem. Getting the order wrong can cost time, money, and even lead to frustrating rework. Here are "What Comes First?" questions that could spark curiosity and conversation among homeowners and builders alike.

It might seem like either could go first, but planning the sequence is crucial. In most cases, plumbing rough-ins are installed before electrical wiring, but in some complex layouts, electricians need to know pipe routes to avoid conflicts. The lesson? Coordination between trades matters more than intuition.

Many homeowners think windows should go in first for security. Surprisingly, roofing usually takes priority. A roof protects the interior works, including window installation, from weather damage. Installing windows before a roof could expose your home to leaks or dust during construction.

It's tempting to finish walls completely before fitting windows. Yet, some builders install windows first to ensure plastering aligns perfectly with the frames. This avoids gaps, uneven edges, and future cracking. Small details like this make a big difference in finish quality.

You might assume ceiling installation comes first to avoid plaster spills, but in many projects, walls are plastered before the ceiling. This sequence allows for seamless wall-to-ceiling joints, giving the room a cleaner, more polished look.

This classic kitchen and bathroom debate is more than personal preference. Installing tiles first usually ensures a flush, level surface for cabinets. Otherwise, cabinet installation might leave gaps or uneven flooring around the edges, creating headaches later.

It's tempting to install sinks, taps, and showers immediately, but tiling often comes first. Wall tiles protect the structure from water damage, and installing fixtures on top of tiles ensures everything sits correctly. Doing it the other way around can mean cutting tiles awkwardly and creating leaks.

Many assume skirting boards are purely decorative and go first. But installing them after flooring allows for a neat finish and prevents boards from floating above the floor or leaving awkward gaps. The right sequence ensures a polished, professional look.

Doors and flooring interact closely, and the order affects clearance, movement, and final appearance. Installing floors first allows doors to be trimmed to the exact height, preventing sticking or scraping later.

It seems logical to hang doors first, but painting ceilings and walls before doors can reduce the risk of paint splatters on expensive woodwork. Some professionals also leave doors off temporarily to allow easier movement of materials in and out of rooms.

Homeowners often rush to install ceiling lights, but painting first ensures no drips or uneven edges around fixtures. Once paint is dry, electricians can safely and neatly install lighting without worrying about mess.

Many think counters go first, but installing the backsplash first can prevent gaps and misalignment. Proper sequencing also makes sealing against water and stains easier, keeping your kitchen functional and beautiful.

It's tempting to landscape first so the yard looks finished, but painting exterior walls comes first. Heavy equipment or paint splatter can ruin newly planted gardens. Proper sequencing protects both your home and your landscaping investment.

Homeowners often want gardens in place before paving, but driveways involve heavy machinery that can damage plants. Paving first ensures your garden can be designed around the finished driveway, avoiding frustration and extra costs.

Construction isn't always intuitive. Small sequencing choices can save headaches, time, and money, and even improve your home's finish. Next time you embark on a building or renovation project, ask yourself: "What comes first?"

These questions aren't just trivia; they're conversation starters for homeowners, builders, and designers, and could completely change the way you approach your next project.
