Isometric Interiors

A pixel art isometric interior kit: 278 pieces on one exact 32x16 diamond grid: walls in 6 finishes (full and cut-away), floors in 10 materials, doors that open, and 25 pieces of furniture drawn in all 4 rotations, each with its own shadow sprite. The same grid as Gridwright Isometric Tiles, so your houses get insides. For life sims, RPGs, tactics, management and cozy games.

Build rooms with this pack: every piece of it is in the Gridwright Isometric Builder, an isometric map maker that runs in your browser, with all seven Gridwright isometric packs inside and Godot, Tiled and PNG export.

Licence in one line: use it in your commercial games; do not resell the files. No credit required.

What you get

• Walls (96): plaster, striped wallpaper with wainscot, wood planks, brick, castle stone and white tiles, 16 pieces each: both back walls, an inner corner, an end post for a wall that stops in the middle of a floor, a doorway and a window on each side, the same set as low cut-away walls to look into rooms, and two mixed corners where a low wall meets a full one.
• Floors (30): oak and walnut boards, parquet, chequered marble, terracotta, slate flags, white marble, red and blue carpet, bathroom tiles; 3 variants each, all repeating every tile.
• Doors (16): a plank door and a panel door for each wall side, 4 frames from closed to open.
• Furniture in 4 rotations (25 pieces): single and double bed, nightstand, wardrobe, dresser; sofa, armchair, bookshelf, TV stand, upright piano; kitchen counter, counter with sink, stove, fridge, dining chair; bathtub, toilet, wash basin; computer desk, office chair, filing cabinet; shop counter with a cash box, goods shelf, display table, tavern table with benches.
• And more: an animated fireplace for each wall side, a dining table, a round table, side table, stool, floor lamp, plants, barrel, crate, waste bin, rugs, and wall decor for both wall sides (painting, mirror, wall shelf, clock, kitchen wall cabinet, curtains).
• 105 shadow sprites: no shadow is baked into the art; draw them at the opacity you like, or not at all.

Made to drop in

• One exact grid: the floor diamond is 32x16 and every file is a multiple of 16 px. Floors tile with no gap and no overlap, walls share one canvas and anchor, and every wall pattern runs on from cell to cell; the build checks it.
• Every rotation drawn on its own, not mirrored, so the light stays on the same side.
• One JSON for everything (isometric.json): every sprite's footprint, anchor, facing, height, wall side, frames and shadow, plus the placement formula and the draw order in the README. Works in Tiled or any engine.
• Clear names: wall_brick_ne_window.png, wall_plaster_post_low.png, sofa_se.png, door_panel_nw_f3.png.
• Single PNGs and sheets at 1x, 2x and 3x, and the palette (.hex, .gpl).
• The rooms in the screenshots were put together from these same sprites, with the shadow sprites on.

Try before you buy

The free sample has 42 sprites: oak, chequered and carpet floors, the plaster wall set (full and cut-away walls, corner, post, doorway, window), the panel door with its 4 frames, a single bed, a nightstand, a sofa, an armchair, a bookshelf, a kitchen counter, a plant, a rug, a painting and a clock, with their shadows.

What it does not include

No characters, no stairs or upper floors, no roofs or outside walls (Gridwright Isometric Tiles has buildings and terrain), no RPG Maker sheets and no engine project files (the README gives the placement formula and the draw order). Windows come in full-height walls only. The art is drawn at 1x; the 2x and 3x files are scaled copies.

Licence

Use and modify in personal and commercial projects. Shipping the sprites inside your game is fine. No resale or redistribution of the assets, modified or not. Credit is appreciated, not required. Not for AI training or NFTs.

How it was made

Every piece is drawn by code: a small ray caster draws each wall, floor and piece of furniture from simple solids on the exact 2:1 grid, turns it to all four sides, lights it from the left and bands it onto 6-tone colour ramps. The code was written with AI-assisted tools. No image generator was used, and no third-party art is included.
