Basement side wall

A component from the London terraced houses pack, with named material slots for stone. It measures about 0.22 m × 2.55 m × 6.76 m (W × H × D) and is already minimal, so all three detail files share one geometry. Place it on its own, or load one of the 1 included assembly that use it.

The picture is a studio render. View in 3D loads the GLB files themselves in three.js; switch between high, medium and low to compare.

Included in London terraced houses (£24), which contains 42 component models and 10 assemblies.

Detail levels	One geometry at every level: 12 triangles is already the minimum for this piece. All three files are included so your loading code can treat it like any other model.
Size (W × H × D)	0.22 m × 2.55 m × 6.76 m
Format	GLB (glTF 2.0 binary)
Compression	Meshopt (EXT_meshopt_compression) + quantised; uncompressed copy in the pack
Textures	3 embedded in the GLB
Material slots	stone
Sockets	stack-bottom, stack-top
Era	victorian, contemporary
On mobile	Start with the low level (12 triangles). What a phone can draw depends on your whole scene; no device benchmark is published yet.
Instancing	Safe to instance (InstancedMesh)

Load it in three.js

import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';

const loader = new GLTFLoader().setMeshoptDecoder(MeshoptDecoder);
const { scene: model } = await loader.loadAsync('models/london-residential-basement-side/high-london-residential-basement-side.glb');
scene.add(model); // 1 unit = 1 metre, origin at the base
