Forbidden City MOC: Axis Layout and Double-Eave Roof
Bottom line first: the hard part of a Forbidden City MOC is the sense of order. Get the central axis layout, the double-eave hip roof of the Hall of Supreme Harmony, and the red walls with yellow tiles right, and the whole thing stands up.
The Forbidden City is a textbook of Chinese architecture. The biggest challenge in a brick build is not any single hall but that sense of order: a central axis, strict symmetry, and levels that step upward. Miss one and it stops reading as the Forbidden City. This guide covers the three cores: the axis layout, the double-eave hip roof, and the red-and-yellow palette.
Start with the axis. A three-part layout works best: an entrance and plaza at the southern end, the main hall in the middle, and a rear hall at the back. The main hall must sit on the center line, with side halls mirroring each other exactly. If your baseplate is large enough, suggest a covered walkway with two rows of columns or palace lanterns receding into the distance. With limited space, build a plaza in front of the hall instead — negative space matters more than filling every stud. Add a Golden Water Bridge across it, using curved plates to form three arched openings, and the scene instantly gains presence.
The double-eave hip roof of the Hall of Supreme Harmony is the centerpiece. A double eave means two roof layers, with the lower eave projecting one ring wider than the upper. The method: first frame the upper eave as a gabled slope, then use SNOT to cantilever a ring of plates outward on all four sides for the lower eave, and tilt the eave edge slightly upward with hinge pieces to mimic the curve of a hip roof. Keep the pitch gentle — Chinese roofs are meant to look broad and relaxed. Use 33-degree slope bricks on the upper eave and 45-degree on the lower, and hold the height difference between the two eaves to 4 to 6 bricks; that proportion looks best.
The color scheme is straightforward. Walls are mostly dark red with bright red accents; columns and doors are red with gold detailing. Roof surfaces use golden-yellow slope bricks throughout, capped by a row of dark grey ridge tiles at the eave. Build the base as a three-tier Sumeru pedestal, stepping inward with dark grey and light grey plates, each tier one stud wider than the one above, and add steps at the front. The main hall immediately looks lifted off the ground.
Bracket sets are where you simplify hardest. At real scale they are far too complex; in a MOC, stack two horizontal layers of 1x2 bricks with side studs, then cap them with a row of 1x1 round plates as column heads. From a distance you get the rhythm of brackets, saving parts while keeping the effect.
Details decide the result. Place a chiwen ridge ornament at each end of the main hall's ridge (an inverted 1x1 gold wedge brick or curved piece works), and line the eave corners with ridge beasts made from 1x1 round plates, increasing in number by odd counts — three, five, seven. The imperial hierarchy shows up right away. Stand a huabiao column on each side of the plaza (a brown bar topped with a 1x1 round plate), and make palace lanterns from transparent yellow pieces on black bases — decorative by day, atmosphere once lit. At miniature scale, simplify all of these into a single round-plate-plus-slope-brick combination; two or three parts carry the meaning.
Common pitfalls: first, an unbalanced roof-to-wall ratio — a large roof taking one third to one half of the building's total height is entirely normal, so don't skimp on height. Second, mismatched yellow part shades — stick to bright yellow or gold, because mixing them looks muddy. Third, axis buildings need to rise step by step from front to back, otherwise the hierarchy collapses. For reference builds, search BrickPlan for Forbidden City MOC instructions and study how others handle the eave height difference and the empty space of the plaza; it is genuinely instructive.
FAQ
Q: What is the hardest part of a Forbidden City MOC? A: The sense of order — central axis, symmetry and stepped levels are all required. Use a three-part layout: entrance plaza at the south end, main hall in the middle, rear hall at the back, with the main hall on the axis and side halls strictly symmetrical.
Q: How do you build the double-eave hip roof of the Hall of Supreme Harmony? A: Frame the upper eave as a gabled slope first, then SNOT a ring of plates outward on all four sides for the lower eave, tilting the eave edge up slightly with hinge pieces. Use 33-degree slopes on the upper eave and 45-degree on the lower, and keep the gap between the two eaves at 4 to 6 bricks.
Q: How do you judge roof-to-wall proportions? A: A large roof occupying one third to one half of the total building height is normal, so don't build it short. Axis buildings should rise from front to back, or the hierarchy is lost, and keep your yellow parts to a single shade — mixing looks dirty.
Q: How do you simplify complex details like brackets? A: Stack two horizontal layers of 1x2 bricks with side studs, then cap them with a row of 1x1 round plates as column heads — from a distance the rhythm of brackets reads clearly while saving parts. At miniature scale, simplify to a round plate plus slope brick combination.
