If your home feels darker and stuffier than it should, there is a $400 to $1,000 architectural detail that fixes both of those problems at the same time, and builders figured it out over a hundred years ago.
Transom windows are the horizontal windows you see above interior doors in older homes, and they solved two real problems at once.
First, natural light into interior rooms. Hallways and inner bedrooms in older homes had limited window access, so transoms above the doors allowed light to pass through from one space to another even when the door was closed.
Second, ventilation. Hot air rises, so an operable transom above a door created a natural cross-flow that pulled cooler air through the house without any mechanical system running at all.
Two problems, one architectural detail, no ongoing energy cost.
The cost to add a transom window in an interior renovation runs anywhere from $400 to $1,000 depending on the door, whether the glass is fixed or operable, and the framing required to support it.
The visual return alone justifies that number. Transom windows make ceilings feel taller, rooms feel more open, and the light that comes through changes how the entire space feels during the day.
The ventilation benefit is a bonus that most homeowners do not even think about until they realize their hallway is no longer the hottest spot in the house.
These are the kinds of details that need to be planned during the design phase of a renovation because adding them after the walls are closed is significantly more expensive and disruptive.
The free renovation playbook covers exactly what to plan for and when, so none of this gets missed before construction starts.

P.S. Some of the best renovation decisions you can make are not new ideas at all. They are old ones that got removed for no good reason and are now coming back into serious builds because the problems they solved never went away.
Most renovation mistakes happen before a single wall comes down. Blake Becker figured that out across 500+ luxury projects in Naples. This playbook tells you exactly what to decide first.
