★★★★★

Absolutely stunning door. The craftsmanship is incredible — you can feel the weight and quality the moment it arrives. Installed it in our master bedroom and it completely transformed the space.

★★★★★

Worth every penny. We were nervous ordering a custom door online but the team walked us through measuring and the door fit perfectly. Hardware included was a huge bonus.

James K.Nashville, TN✓ Verified

★★★★☆

Beautiful door, great quality wood. Delivery took about 3 weeks which was within the estimate. Only wish they had more stain color samples available to ship.

The X, Reduced

Strip a barn door of its planks, its distress, its clavos and its warm stain, and what remains is a rectangle with an X in it. The Modern X is that door. A flat matte black face, a crisp perimeter frame, and one X spanning corner to corner with nothing else on the slab.

In matte black the brace does not read as wood. It reads as a line. Depending on where you stand, the X is either a dark graphic on a dark field or a set of shadow edges catching the room light, and it changes as you move past it.

It is the least rustic door we make that still has a brace on it, which turns out to be exactly what a lot of modern houses want.

Design Details

Single Full Span X

One X, corner to corner, at full scale. Nothing smaller, nothing doubled, no secondary framing inside it.

Flat Matte Black

A dead flat finish kills reflection and turns the face into a plane. The only highlight in the door is the edge of the brace.

No Plank Lines

The field between the braces is smooth. Without seams, the geometry has nothing to compete with.

Square Perimeter Frame

A clean stile and rail border squares the composition and gives the X somewhere definite to land.

Black Shows Everything

A dark flat finish is the most punishing surface in a workshop. Every ripple, every proud joint and every bit of movement in the panel shows up under a raking light. We build these solid and flat in Pipersville, Pennsylvania, and we finish them to be looked at closely. If the panel ever moves on you, the lifetime warranty covers it.

How to Measure Your Opening

A few quick measurements and we build your door to fit perfectly.

Measure the Width

Measure across the opening with the trim included. If there is no trim, measure just the width of the opening itself.

Measure the Height

Measure the total height of the opening including the trim. If there is no trim, measure just the height of the opening.

Leave Room for Hardware

Allow at least 6″ of clearance above the opening (or above the trim) for the track hardware. Bypass doors need a minimum of 9″.

We Handle the Coverage

No trim? We add 4″ to the width (2″ each side) and 1″ to the height for proper coverage. With trim, we build the door to extend slightly past it.
