The Forge House is a 4-5 hour build across 8 numbered bags and 368 assembly steps, which works out to roughly 4.3 pieces per step - a higher density than most Lumibricks sets, meaning each step adds visible progress. The build begins with the ground-floor forge workshop, and this is where the set immediately earns your attention. You assemble the working forge with its tool racks, sharpening stations, and weapon displays, then route the first LED strings into position - three breathing red lights that will simulate glowing embers in the forge. The moment those first LED elements go in behind the transparent flame pieces, you get a preview of what this model is going to look like fully assembled, and it is compelling.
The towering chimney is the architectural centerpiece, and building it is satisfying. It rises through all three floors and dominates the roofline, giving the model a vertical focal point that anchors the entire design. Unlike sets where the chimney is a small decorative afterthought, the Forge House chimney is a structural element that you build around - it shapes the interior spaces and determines where rooms can go. The second floor - the forger's living and dining quarters - provides a change of pace from the workshop, with medieval furniture and warm interior details that remind you there is a person who lives above this fiery workspace.
The third floor splits into two bedrooms: the master forger's room (complete with an ancestral sword mounted on the wall) and the apprentice's quarters (with weapon-forging scrolls on display). Sixteen printed elements and zero stickers throughout the entire build. This is how it should be done. The build has a therapeutic quality that many builders will appreciate - the rhythmic progression from hot, industrial ground floor to warm, domestic upper floors mirrors a journey from work to rest, and the pacing feels natural and unhurried.
The breathing LED technique is the star of this set and the best single lighting effect in the Lumibricks medieval lineup. Three red LED modules are wired to a slow pulse cycle that dims and brightens in a pattern that genuinely simulates forge embers. Placed behind transparent orange and red flame elements within the forge opening, the effect is convincing enough to stop people mid-conversation. This is not a static glow - it breathes, and that animation transforms a static model into something that feels alive. The technique teaches a fundamental lesson about LED lighting: movement and variation create atmosphere that static light cannot match.
The chimney construction technique is equally instructive. Building a structural element that rises through three floors while maintaining stability and accommodating removable floor sections requires careful planning at the foundation level. Lumibricks uses a combination of interlocking brick columns with Technic pin reinforcement at each floor boundary to create a chimney that feels solid without being permanently bonded to the floors around it. This technique scales directly to any MOC with a central vertical element - clock towers, lighthouse cores, or elevator shafts.
The tool rack and weapon display construction on the ground floor demonstrates efficient small-space detailing. Clip-and-bar mounts hold axes, swords, and hammers on wall panels without occupying floor space, and the sharpening station uses a round tile on a modified bracket to suggest a grinding wheel. The quick-disassemble floor system uses the same modular approach seen across the Lumibricks medieval range, allowing each level to lift off for interior access.

At 1,595 pieces, the Forge House parts inventory is solid and practical. The color palette centers on dark grey, dark brown, and reddish brown - the essential medieval building colors that every castle and village MOC builder needs in bulk. The transparent orange and red flame elements are a genuine bonus. These are always useful and often hard to find in quantity from official LEGO sets. The weapon accessories - swords, axes, hammers, and a mounted ancestral blade - add flavor to any medieval display.
The 16 printed elements include forge insignia, scroll details, and decorative tiles that add authenticity without stickers. The structural bricks for the chimney column provide a useful supply of interlocking elements in dark grey tones. The wall elements and modified bricks for the stone-and-timber facade are deeply practical for any builder working on historical architecture. All pieces are fully compatible with LEGO and other major brands, integrating seamlessly into existing collections.
The LED kit is more sophisticated than most Lumibricks sets at this price point. The breathing red forge lights are a step above the standard warm-white modules, and the 11 glow positions across 5 strings give you more lighting coverage per dollar than sets costing $20-30 more. The community rating of 8.8/10 across 19 reviews on Merlin's Bricks confirms that this set consistently delivers for builders. The 8-bag numbered build keeps the process organized without making you dig through mountains of unsorted pieces.

The Forge House arrives with 8 numbered bags containing 1,595 pieces, a complete LED lighting kit with 5 light strings and 11 customized glow positions (including 3 breathing red forge LEDs) plus USB power cable, 4 minifigures (master forger, apprentice, and two additional characters), 16 printed decorative elements (zero stickers), weapon accessories including swords, axes, and a mounted ancestral blade, transparent orange and red flame elements for the forge, and a detailed instruction booklet with 368 steps. The build produces a three-story medieval forge with towering chimney, ground-floor workshop, living quarters, and split bedrooms with quick-disassemble modular floors for interior access.
The Forge House has the best lighting system in the Lumibricks medieval lineup. Five light strings with 11 customized glow positions create a layered atmosphere that changes as your eye moves up the building. The ground floor is the showstopper - three breathing red LEDs simulate forge embers behind the transparent orange and red flame elements, creating a flickering glow that genuinely looks like an active fire. Two warm yellow torches frame the entrance, drawing you into the workshop. The effect is mesmerizing in low light, and it makes this set one of the strongest night-display pieces in the entire Lumibricks catalog.
The upper floors shift to warm yellow oil lamps and candles, creating a lived-in warmth that contrasts beautifully with the industrial heat below. The towering chimney gives the model a distinctive vertical profile - at roughly 13 inches tall, it has more height than footprint, which makes it visually striking on a shelf. The pitched roofs, stone-and-brick facades, wooden beams, and columns are all executed in traditional medieval architectural style. The 4 minifigures bring the workshop to life, and the modular quick-disassemble design means you can pull floors apart to admire the interiors without any frustration.
Placed alongside other medieval Lumibricks sets - the Tailor Shop, the Apothecary, the Market - the Forge House becomes the industrial heart of the village. Its breathing red glow anchors one end of the street while the softer candlelight of the shops creates a visual gradient of warmth and activity. It photographs beautifully, especially in dim lighting where the forge glow really commands attention.
At 1,595 pieces for $89.99, the Forge House hits a sweet spot for price-per-piece with LED lighting and 16 printed elements included. An equivalent official LEGO blacksmith set at this piece count - like the retired LEGO Ideas Blacksmith - would run $150+ and include no lighting. Add a $30-40 aftermarket LED kit and you are at $180-190 for a comparable display result. The Lumibricks Forge House delivers the same atmospheric storytelling for roughly half the price, which continues to be the brand's strongest competitive advantage.
The breathing red forge LEDs alone add premium value that standard warm-white lighting cannot match. The 11 glow positions across 5 strings provide more lighting coverage than many sets at higher price points. The parts palette is deeply practical for medieval builders, the printed elements eliminate sticker frustration, and the build experience is engaging from start to finish. For anyone building a medieval collection, the Forge House is one of the best value propositions available - essential for the display effect, competitive on price, and satisfying as a build.

At $89.99 with 1,595 pieces and 11 LED glow positions, the value is outstanding. This is a set that looks good during the day and spectacular after dark.
