Igloo MOC Guide: Curved Snow Dome in About 1,800 Pieces
The short version first: this igloo MOC uses roughly 1,800 pieces, measures 26 cm across and 22 cm tall, takes about 5 hours if you build 2 hours a day, and costs around 330 CNY in parts. The dome is built layer by layer from white curved pieces that pull inward as they rise, and it sits on a snow base with a half-sunken entrance tunnel. Minifigures and arctic animals both fit comfortably. The instructions come from the brickplan platform, with the parts list split by section, so it works well for beginners and for building with kids.
Step 1: Lay the snow base
Start with a 20x20 stud baseplate and build it out into a round snow field, covering the surface with white plates. Keep the rim uneven — raise some edges and drop others so it reads as snowdrifts rather than a flat disc. Leave a 16x16 stud footprint free in the middle for the igloo itself. Around the outside, add a few small icicles and a snowman. This step uses about 400 pieces.
Step 2: Build the curved dome
The dome is the heart of the model. Begin with a bottom ring of white curved pieces, then bring each new layer slightly inward, stacking the way real snow blocks lean toward the centre, until a round cap piece closes the top. Lock every layer with clips so nothing drifts out of round, and fill the gaps between curved pieces with small parts. Leave an arched doorway on one side of the dome. This step uses about 700 pieces.
Step 3: Entrance tunnel and interior
The entrance is a semi-sunken structure: a white corridor runs outward from the doorway, covered on top with plates and kept low enough that a minifigure has to stoop — which is exactly the feel of a real igloo entrance. Inside, place an ice bed and a fur cushion, and set an oil lamp against the wall so the light comes through the white pieces softly. This module uses about 400 pieces.
Step 4: Arctic scene and finishing
Finish by setting a sledge, a harpoon and a few polar bear or seal figures on the base, and scatter a handful of glitter pieces across the snow to suggest reflected light. Fit a warm-light brick inside the dome — once it is powered, the whole igloo reads as a snow house lit up at night. When everything is placed, check your parts against the section lists on the brickplan instructions page.
FAQ
Q: Where do I download the igloo MOC instructions?
A: Search for "igloo" on the brickplan site and you will find this set of instructions. It provides high-resolution step-by-step views and a parts list split by section. The PDF is free after registering, and you can zoom in on your phone to see exactly how the curved pieces are placed.
Q: Will the curved dome end up lopsided as I build?
A: No. The key is keeping the number of curved pieces identical on every layer. The instructions mark the inward count for each level — just build layer by layer and align the clips on each ring, and the dome stays round.
Q: Is this MOC suitable for beginners?
A: Very. The part count is small and the structure is simple, so it comes together in about 5 hours. The inward-curving technique also gives newer builders a genuinely interesting skill to practise, which makes it a good first scene MOC.
Q: How much does it cost to gather all the parts?
A: About 330 CNY. The white curved pieces and the cap piece are the biggest share at roughly 120 CNY. The parts list on the brickplan page lets you count the white parts you already own before ordering the rest, which saves a fair amount.
Q: Can it be combined with arctic animal MOCs?
A: Yes. The base and the animals are both at standard stud scale, so brickplan polar bear, seal and similar animal MOCs can go straight onto the igloo's snow field to form a complete arctic scene.
