Compare Horizon Grid MK.I and MK.II sci-fi terrain sets on size, compatibility, and tabletop role. See which modular terrain grid fits your 28mm battlefield.
Quick answer
Start with the Horizon Grid MK.I if you need a standalone single-story building for 28mm sci-fi games; add the MK.II only when you want to stack a second story with a balcony on the MK.I base. The MK.II is an expansion, not a substitute.
The dependency that decides your first purchase
The MK.II kit is explicitly designed to work with the Horizon Grid MK.I (SFT001) and requires that base building. That makes this less a choice between two equal kits and more a choice between one complete building and a two-story upgrade path.
If you buy only the MK.II, you will not have the ground floor it needs. The practical sequence is MK.I first, then MK.II when you want verticality.
Table footprint and vertical presence
Both kits share the same 7.75" x 6.5" footprint, so they occupy the same table area. The MK.I is a single-story building with a roof; the MK.II is a second story with a balcony that stacks on top.
That means the MK.II does not add more ground-level coverage—it adds height and a balcony level. If your board already feels crowded, stacking is a way to gain vertical play space without spreading out.
Doors, assembly, and painting
The MK.I includes functioning doors, which matter for line-of-sight and entry rules in many 28mm wargames. The MK.II also lists functioning doors, so the stacked building keeps that interactivity on the upper level.
Both are laser-cut 3mm MDF kits that come unpainted and require assembly. Neither is a pre-painted terrain piece, so budget time for building and finishing before your first game.
Trade-offs to weigh before you buy
- Buy MK.I alone: Choose this if you want one complete building with a roof and functioning doors for a 28mm sci-fi table. You get a standalone kit with no dependency, but no second story or balcony. Best first purchase if you are building a new battlefield from scratch.
- Buy MK.I + MK.II together: Choose this if you want a two-story building with a balcony. You must own the MK.I base; the MK.II cannot be used alone. The trade-off is more assembly and painting time for vertical play. Plan to build and paint both kits before your first game.
- Buy MK.II as an add-on later: Choose this if you already own the MK.I and want to expand upward without changing your table footprint. The trade-off is that the MK.II adds height, not extra ground coverage. Check that you have the MK.I (SFT001) before ordering the MK.II.
