This coffee table started as a salvaged six-lite window sash, the kind of chippy-white, multi-pane unit you’d normally see hung in a wall opening, not sitting in a driveway. Instead of building a box and hinging the window on top as a lid (the more common version of this project), this build cuts the sash apart and uses its own panels for the table’s sides and legs, with a second matching sash inset as the fixed glass top. The glass grid that used to divide a window into panes now divides a tabletop.
Starting Material: A Salvaged Window Sash
The earliest photos in this build show the sash exactly as it was before any work began, a weathered, chippy white six-lite unit lying flat on a shop workbench outdoors, its old glazing and paint layers still intact, with a second nearly identical sash leaning against the house nearby. Pliers, a screwdriver, and a hammer are already staged on top, which is the first clue this piece was going to be disassembled and rebuilt rather than refinished as-is.
A close-up from the same early stage shows the sash’s original glass panes and wood muntins (the thin dividers between panes) with wood shavings scattered across the glass, evidence of the muntins being trimmed and reworked before assembly.
Building the Box: Sash Panels as Sides and Legs
The build photos jump next to the sash cut down and tipped up into a box shape directly on the driveway, still unpainted, showing raw and painted wood side by side where cuts were made. What’s easy to miss on a first look is that the “legs” and “sides” of the table aren’t separate lumber at all; they’re sections of the same window sash, glass panes and all, standing on edge. That’s the core trick of this build: instead of framing a new box and adding the window as decoration, the window’s own structure becomes the table’s structure.
A later shop photo shows the same assembly further along, now in white primer with bare wood still showing through in patches, sitting under an LED work light on the shop bench. At this stage the four-pane glass top and paneled sides are both clearly in place, what’s left is paint and final cleanup.
A Detail That Gives Away Its Past Life
One of the more interesting details only shows up once the table is finished: a close look at the top rail reveals a pair of round holes left over from the original hardware, almost certainly a door lockset or sash pull from whatever door or window this piece was salvaged from. Rather than filling and hiding them, they’re left visible, which is a small but honest touch on a piece built entirely from reused material.
The Finished Table
The finished piece is painted a soft gray over what was originally white primer (the gray reads warmer and less stark than the raw primer stage), with all four glass panes, top and sides, intact and clean. It photographs as a genuine glass-top coffee table: low, four-legged, with the original window’s mullion grid doing double duty as both structure and pattern. The glass sides mean you can see straight through the base from any angle, which is the most distinctive visual trait carried over from its window origins.
Why Build a Table From a Window Instead of a Box
Most published versions of this idea use the window as a hinged lid on top of a separately built storage box, a shadow-box coffee table. This build takes a different approach by cutting the sash itself into structural sections, which means less new lumber overall and a more visually consistent piece (every surface, top and sides, carries the same glass-and-muntin look, instead of just the top). The tradeoff is that it demands more from the salvaged material itself, the sash has to be sound enough, and square enough, to serve as actual structure rather than just a decorative panel, which likely explains why the raw-material photos show two nearly identical sashes on hand rather than just one.

This table joins two other coffee tables already in the portfolio, a mitered chevron-pattern reclaimed-wood coffee table and a minimal modern coffee table, forming a natural coffee-table sub-cluster. It also shares its raw material with the backyard bar project, which used two reclaimed window sashes as its own structural centerpiece, a natural material-based connection distinct from the coffee-table cluster.
