Direct answer: how to turn a neighborhood/block into a world

You can do it, and you don’t have to build it block by block yourself. In TopoBlocks, search the address of your neighborhood or block, box-select the area you want recreated on the map, and the app reads the public building footprints, roads, and water from OpenStreetMap, then layers on open elevation data (AWS Terrain) to recreate the terrain too, and finally uses an open-source tool to generate an importable .mcworld.

But set your expectations correctly first: this is an approximate recreation based on public data, not a block-by-block copy of what your real neighborhood looks like. Building footprints, street layout, and elevation will come through, but the specific exterior and interior of a building won’t be reproduced as the actual building in reality. So before generating, the app gives this area a quality score for free and provides a low-resolution 3D preview — the quality score is an estimate of data coverage (not a guarantee of accuracy), so you can first see “does this area have enough data, does it look close enough,” and pay to generate only if it’s worth it.

Step-by-step

  1. Search your neighborhood/block — search by neighborhood name, street address, landmark, or just your current location, and move the map to your area.
  2. Box-select the area — drag to box out the area you want generated. The bigger the box, the bigger the world, the higher the price tier, and the longer it takes; the smallest tiers are usually enough for a single neighborhood or street.
  3. View the quality score + 3D preview for free — first confirm this area’s data coverage and recreation quality, then decide.
  4. Pick a template and generate — choose from four gameplay templates (Faithful Recreation / Survival-Friendly / City Exploration / Treasure Hunt), confirm the price, and generate an importable .mcworld.

Pricing, coverage, and a few honest notes

  • Fixed price by area. Generation is split into 6 tiers by selected area (roughly 0.2-500 km², ¥19-¥239), and the price is shown fixed the moment you box-select — it isn’t metered. A neighborhood/block generally falls in the smallest tiers. The price shown in the app is authoritative; if a generation job fails, you’re refunded automatically.
  • Sparsely-mapped places come out empty. If your home is in an area with sparse mapping, with little building and road data, the result will come out fairly empty — this is exactly what the free quality score warns you about ahead of time. To compare against dense urban results, see Turn a city into a Minecraft real map.
  • It never overwrites your existing worlds. Every generation is a new file and never overwrites any save you already have on your device; the source data stays traceable.
