A Display Built for the Grand Staircase

The LEGO® Ideas 21373 Downton Abbey is a build of two halves: the great house outside, and the famous grand staircase inside — the staircase is the scene everyone wants to show. The KGBOX display for LEGO 21373 Downton Abbey was designed specifically for it, in four formats: an LED wall frame that hangs the staircase scene on your wall, two sealed 5 mm cases, and a collector case that sets the house on its own grass estate at sunset.

LEGO® set not included. This product is the KGBOX display only — we sell display cases and frames. The LEGO® set shown in the photos is not included.

Every staircase format gives your minifigures three levels to stand on, so the household can take their places on the stairs and gallery. Still planning the setup? Our Downton Abbey wall display guide walks through all four formats in real rooms, and this display is one of the set-specific designs featured in our complete guide to LEGO display cases.

Product Features — Four Ways to Display Downton

3D Staircase Minifigure Stand
The staircase formats recreate the grand staircase as a layered 3D scene with three levels of minifigure positions — the household assembled on the stairs, as it should be.

Two Adjustable Top Spotlights
On the LED Wall Frame, two spotlights aim down the staircase, modelling every figure and balustrade in warm light.

Lit Window Panels
The leaded windows in the UV-printed backdrop glow from inside, so the hall looks occupied after dark — the Downton effect in miniature.

UV-Printed Backdrops
Castle interior, grand staircase and Highclere crest on the staircase formats; a sunset estate landscape on the Basic and Collector cases. (UV-printed is the artwork printing method, not a UV-protective coating.)

Sealed, Dust-Proof Cases
The three display-case formats are sealed 5 mm (or 3 mm Collector) acrylic with magnetic front doors — dust-proof on a tabletop, and the thickened cases can also wall-mount. The open wall frame is wall-mounted only and is not dust-proof.

Designed by Collectors
KGBOX displays are designed by collectors and made in our own factory — and every one is covered by a lifetime warranty, with 90-day returns and free US shipping.

Product Details

Most display cases show a building from the outside. Downton deserves the inside: the staircase formats put your minifigures on three levels of the great stairs under spotlights, with the windows lit behind them, while the estate formats present the house itself at dusk — sunset backdrop, grass lawn, the castle's name lit at the front. Whichever format you choose, assembly takes one person about 30 minutes, lit editions run on USB with the cable included, and the wall frame ships with hangers (wall anchors and screws are not included).

🏰 Downton Abbey, four ways to display it. This KGBOX line is made for the LEGO® 21373 Downton Abbey set. Choose the LED Wall Frame to hang the grand staircase on your wall, the 5mm Thickened Light Case for a sealed staircase box with warm edge backlight, the 5mm Thickened Basic Case for a simple UV-printed display, or the Collector Display Case for a premium sunset estate box with grass base and lit details.

🪜 LED Wall Frame – hang the hall on your wall. The upper half recreates the castle's famous grand staircase as a layered scene with three levels of minifigure positions. Two adjustable spotlights on top aim down, and the leaded windows in the UV-printed backdrop glow from inside. Wall-mounted only – cannot sit on a tabletop, and open design means not dust-proof.

🔲 5mm Thickened Light Case – sealed, sturdy, glowing. Same grand-staircase layout as the wall frame, built as a sealed 5mm thick acrylic box. Warm LED backlight runs around the inner edges, illuminating the UV-printed castle interior. Magnetic front door, dust-proof, tabletop display, can also be wall-mounted. USB-powered, cable included.

🌅 5mm Thickened Basic Case – clean and simple. A 5mm thick acrylic display box with UV-printed sunset estate backdrop on the back and bottom. Magnetic front door, dust-proof, tabletop or wall-mount. No lighting.

✨ Collector Display Case – the estate at dusk. A 3mm clear acrylic cube with a UV-printed sunset Highclere estate backdrop, a raised base with artificial grass, illuminated front lettering, and a small lit castle nameplate at the front-left. Tabletop display.

🔌 USB-powered, cable included. All lit editions run on USB – a USB cable ships with the case.

🔩 Fast 1-person assembly. Every version assembles in about 30 minutes using the included instructions.

⚠️ Mounting notes. The wall frame comes with hangers, but wall anchors and screws are not included. The wall frame is open (not dust-proof) and wall-mount only. The three display-case versions are sealed with magnetic doors and are dust-proof.

📌 Please note:  Peel all protective film before use. LEGO set NOT included.

Frequently asked questions

Does the LEGO set come with the display?

No. LEGO set 21373 is not included — you are buying the KGBOX display format you select (wall frame or case), each sold separately. KGBOX sells display cases and frames only.

Which of the four formats should I choose?

Choose the LED Wall Frame to hang the grand-staircase scene on a wall; the 5 mm Thickened Light Case for the same staircase scene sealed and backlit; the 5 mm Basic Case for a simple sunset-backdrop box (backlight version available); or the Collector Display Case for the house on a grass estate base with lit lettering.

Is the wall frame dust-proof?

No — the wall frame is an open design and is wall-mounted only; it cannot sit on a tabletop. The three case formats are sealed with magnetic front doors and are dust-proof.

How is the lighting powered?

USB powered, with a USB cable included, on every lit edition (wall frame, light case, backlit basic case, collector case).

What do I need to hang the wall frame?

Hangers are included; wall anchors and screws are not included. Every version assembles in about 30 minutes for one person.
