Low Poly Dungeon Keep - Modular Stone Castle Kit

Build dungeons, keeps and castle interiors in minutes.

Low Poly Dungeon Keep is a complete modular stone castle and dungeon kit. 179 ready-to-use prefabs snap together on a single 4 m grid: stone and timber walls, floors, pillars, stairs, platforms, doors, gates, ceilings and a full set of props. Every surface is coloured from one tiny palette texture, so the whole kit shares one material and can be re-coloured in a click.

WHAT IS INSIDE

- Architecture, 68 prefabs: 20 walls (plain, arched door and window, slit window, niche, buttress, crenellated, cracked, mossy, broken, timber frame), 15 floors (stone, cobble, checker, wood, grate, hole, rune), 14 pillars and columns, 6 stairs, 4 platforms and fences, 6 doors, gates and grilles, 3 ceilings (flat, barrel vault, timber beams).

- Props, 111 prefabs: furniture, containers, lighting, decor (banners, rugs, weapons, paintings), statues, fountain, well, altar, crypt and dungeon dressing, magic items (crystals, portal arch, cauldron, potions), nature and small treasure.

- Two demo scenes: a walled keep with courtyard, throne hall, library, armory, dungeon and crypt built only from kit pieces (camera "Go to" list, day / dusk switch, ceiling toggle, palette picker), and a gallery with every prefab on a labelled board.

- PDF documentation: grid and pivot rules, URP and Built-in setup, palette system, script reference and a catalogue of every prefab.

FEATURES

- Modular grid: 4 m cells, 3.6 m walls, pivots on a 2 m grid, seamless tiling, corner posts to hide junctions, and a "Snap Selection To Grid" menu command.

- One material, four palettes: Classic, Frostbound, Overgrown and Cinder. Swap them in one click or at runtime with PaletteSwitcher.

- Working doors: hinged doors, double gate, cell door, trapdoor and sliding portcullis (Open / Close / Toggle from code, UnityEvents or a trigger).

- Living light: flickering torches, braziers, candles and lanterns; glowing crystals and runes.

- Light on the GPU: 342 triangles per mesh on average, colliders, static flags and lightmap UVs on every prefab.

- Clean project: namespaced scripts with assembly definitions, safe with Domain Reload disabled, no extra packages.
