Windows and exterior doors are a substantial part of a modern custom-home budget.
Large sliders, retractable glass walls, corner windows, impact-rated openings, and oversized doors look wonderful. They can also cost astonishing amounts of money.
It is easy to spend tens of thousands of dollars on one large opening once engineering, structural support, installation, and waterproofing are included.
So understand your window and door budget early.
Glass is architecture. It controls light, frames views, creates privacy, connects inside and outside, and shapes exterior elevations.
Spend the best glass where the best views are.
If the family room faces water or a beautiful pool, that is probably where the major glass investment belongs.
Treat each important window as a picture frame. What picture are you putting inside it?
Stand where the sofa, kitchen island, desk, and bed will actually be and ask what you see.
More glass is not automatically better. Glass creates heat gain, glare, privacy problems, furniture-placement problems, and maintenance.
Think about the sun. A west-facing glass wall in a hot climate is a different problem from shaded glass facing another direction.
Think about nighttime privacy too. A transparent wall becomes an illuminated display case after dark.
Use standard sizes where they make sense and spend custom-window money where it creates real impact.
Your goal is not the maximum amount of glass. It is the maximum value from the glass you buy.
