Yes, absolutely. At our planter box factory, we specialize in creating custom-sized planters that fit virtually any space — including those tight, awkward gaps between a window and a door. Many homeowners face this exact challenge: they want greenery in a specific spot, but standard off-the-shelf planters are either too wide, too deep, or just awkwardly proportioned. That’s where our custom manufacturing process steps in.

We start by asking for your exact measurements. Whether the gap is 8 inches, 6 inches, or even narrower, our design team can engineer a planter that slides perfectly into place. We use high-grade aluminum, which allows for slender walls while maintaining structural integrity — meaning we can build a planter that is just 4 inches wide without sacrificing durability or drainage. The material also resists rust, UV damage, and warping, making it ideal for both indoor and outdoor placement near windows and doors.

Moreover, we offer options in depth and height. If your window sill is low or the door frame is tall, we can adjust the dimensions precisely. Color matching is also available, so your planter can blend seamlessly with your window trim or door frame, or stand out as a deliberate design accent. Every planter is fabricated in our factory, laser-cut and welded to your exact specifications, then powder-coated for a finish that lasts years.

In short, there is no “one size fits all” when it comes to unique architectural spaces. Our factory’s entire operation is built around custom fabrication. We welcome your specific requirements — just measure the gap and let us take it from there. Your window-door gap can finally become a living, breathing vertical garden.
